Description

Data acquisition method and device

Technical Field

The embodiment of the invention relates to the technical field of Internet, in particular to a data acquisition method and device.

Background

With the rapid development of internet technology, a large number of users can issue a large amount of dynamic information (feeds) on the internet, so that other users can also obtain a large amount of information stream (feeds stream) data such as dynamic news, friend dynamics and the like from the internet. For example, when a user refreshes the feeds stream data through clients such as social applications and information applications, the clients can acquire the feeds stream data from the server for display, and when the feeds stream data contains a plurality of records in the process of data acquisition, the server can perform paging processing on the feeds stream data, and then return corresponding paging data to the clients according to the request of the clients for browsing by the user.

Currently, the feeds stream paging process can be broadly divided into two types: the page number paging mode and the displacement paging mode, however, the page number paging mode requires that the client explicitly knows the page number, then the page number of the current page is sent to the server to obtain the paging data of the current page when data is obtained each time, the displacement paging mode requires that the client explicitly knows the ordering field, then the client determines the displacement value according to the ordering field and the last record of the previous page when data is obtained each time, and sends the displacement value to the server to obtain the paging data of the current page. It can be seen that the client and the server are strongly coupled in these two paging modes, so that the server cannot flexibly control the paging mechanism, for example, the server cannot flexibly switch from one paging mode to the other paging mode.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The embodiment of the invention provides a data acquisition method which can be applied to a system comprising a server and a client. The client and the server can communicate data through a network.

Here, the server may be implemented by an electronic device having functions of data acquisition, transmission, processing, storage, and the like, for providing service support related to data acquisition to the client. For example, the server may be a social platform, an information platform, and the like. Here, the type of the server is not specifically limited in the embodiment of the present invention.

In practical applications, the client may be implemented by an Application (APP) on various forms of electronic devices. For example, the client may be an APP that has a feeds stream scene, such as a social application, a news information application, etc. on the electronic device. Here, the type of the client is not specifically limited in the embodiment of the present invention, and all clients that can access the server are within the scope of the embodiment of the present invention.

Specifically, the electronic device described in the embodiments of the present invention may be a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a personal digital assistant (PersonalDigital Assistant, PDA), a navigation device, a wearable device, a portable computer, or a fixed terminal such as a smart tv, a desktop computer, or the like. Here, the embodiment of the present invention is not particularly limited.

In practical application, the data acquisition method can be applied to various occasions where paging processing is required to be performed on a large amount of data in the data acquisition process, for example, a client needs to acquire a large amount of feeds stream data such as dynamic news, friend dynamics and the like from a server.

The data acquisition method provided by the embodiment of the invention is described below with reference to the above system.

Fig. 1 is a schematic flow chart of a data acquisition method in an embodiment of the present invention, and referring to fig. 1, the data acquisition method may include:

s101: the client sends a data acquisition request to the server, wherein the data acquisition request carries an original field value corresponding to the paging field.

The data acquisition request is used for requesting the server to issue paging data of the current page and a new field value corresponding to the paging field.

As an example, when a user refreshes feed stream data through a client such as a social application or an information application, the client sends a data acquisition request for requesting to issue paging data to the server, so as to request the server to issue the paging data of the current page and a new field value corresponding to the paging field to the client according to an original field value corresponding to the paging field.

Here, the paging field is set according to a general paging protocol agreed in advance.

In practical applications, in order to implement flexible paging processing, for example, switching the paging mode in the pre-stored paging configuration information from the page number paging mode to the displacement paging mode, switching the ordering field in the pre-stored paging configuration information from the ordering field 1 to the ordering field 2, switching the number of the paging records in the pre-stored paging configuration information from the first value to the second value, etc., a general paging protocol in which the server and the client perform the paging data interaction may be agreed, and specifically, the content of the general paging protocol may include: the paging field may be a preset first character for representing the first page data, a preset second character for representing the last page data, which is different from the preset first character, or a preset third character for representing other page data except the first page data and the last page data, according to the difference of the types of the paging data.

Then, based on the general paging protocol, when the client requests that the paging data of the current page issued by the server is the first page data, the original field value of the paging field sent to the server by the client is a default filled preset first character for representing the first page data; when the client requests that the paging data of the current page issued by the server is other page data except the first page data, the original field value of the paging field sent to the server by the client is the field value which is simultaneously returned to the client by the server in the process of issuing the previous page data to the client, namely, a preset third character used for representing other page data except the first page data and the last page data. It can be seen that the meaning of the paging field is almost transparent to the client, except that when the first page data is acquired, the field value of the paging field sent to the server by the client can be filled in the request parameter of the data acquisition request by default by the client, and in other cases, the field value of the paging field sent to the server by the client is sent to the client in advance by the server in the previous interaction process.

As an example, where the paging field is implemented by an offset field, the preset first character is implemented by character 0, and the preset second character is implemented by character-1, then the generic paging protocol content may include: an offset field, 0 represents the first page data, -1 represents the last page data. Wherein when the client requests the first page of data, the offset defaults to fill 0.

In addition, when the general paging protocol is designed, the paging field can be of a character string type, the field value of the paging field can be of a numerical value type or of a character string type, and the fact that the paging field can represent different meanings at the server side is ensured, so that the server side is convenient to flexibly control the paging mechanism, such as switching the paging mode and the like.

As an example, in a specific implementation process, S101 may include: the client obtains an initial data acquisition request; if the paging data of the current page is the first page data, adding a preset first character serving as an original field value corresponding to the paging field into the initial data acquisition request to obtain the data acquisition request, wherein the preset first character is a character which is preset with the server side and is used for representing the first page data.

S102: the server determines the paging data of the current page and a new field value corresponding to the paging field based on the original field value and preset paging configuration information;

Specifically, after receiving a data acquisition request of paging data, which is sent by a client and carries an original field value corresponding to a paging field, the server knows that the client requests to issue the paging data of the current page, and then, the server responds to the data acquisition request to acquire preset paging configuration information, and then determines the paging data of the current page requested by the client according to the original field value of the paging field sent by the client and the acquired paging configuration information, and determines a new field value corresponding to the paging field required to be returned to the client so as to indicate whether the paging book of the current page has the paging data of the next page to the client.

As an example, the above-described paging configuration information may include: ordering field, number of page records, and paging mode.

In practical applications, the paging control of the server is configurable, and page configuration information such as a sorting field, a paging record number, a paging mode and the like can be recorded in a certain storage mode. When a data acquisition request from a client is received, the paging configuration information is read from the storage space, where the sorting field refers to a field capable of sorting a plurality of records in the pre-stored information stream data. For example, when the information stream data is a merchandise display list including a plurality of merchandise records, the sorting field may be set to the creation time of the merchandise or the modification time of the merchandise, and of course, may be other fields capable of sorting the plurality of records in the information stream data, such as the merchandise name, etc. The embodiments of the present invention are not specifically limited herein for the type of the ordering field, and may be set by those skilled in the art according to the service requirements.

Here, the number of page records refers to the maximum number of records that can be displayed per page. For example, the number of page records may be set to 5, 10, and so on.

Here, the paging method refers to a method used by the server to perform paging processing on the information stream data. For example, the paging mode may be a page number paging mode or a displacement paging mode, and of course, may be other types of paging processing modes, where the type of paging mode configured by the server side in the embodiments of the present invention is not specifically limited.

S103: the server sends a request response to the client, wherein the request response comprises: paging data of the current page and a new field value corresponding to the paging field;

in practical application, based on the general paging protocol, when the client requests that the paging data of the current page issued by the server is the last page data, the server issues the paging data of the current page, and simultaneously sends a new field value of the paging field of the client to be a preset second character for representing the last page data; when the client requests that the paging data of the current page sent by the server is not the last page data, the server sends the paging data of the current page, and the new field value of the paging field sent to the client is a preset third character used for representing other page data except the first page data and the last page data, and the new field value can be sent to the server again when the client requests to send the next page data.

Specifically, after the server obtains the paging data of the current page requested by the client according to the original field value corresponding to the paging field and the preset paging configuration information and determines the new field value corresponding to the paging field, the server sends the paging data of the current page and the new field value corresponding to the paging field to the client as a request response, so that the client renders the paging data of the current page, and determines whether to obtain the paging data of the next page based on the new field value corresponding to the paging field returned by the server.

S104: the client renders paging data of the current page;

as an example, after the client receives the paging data of the current page requested by the client, the paging data of the current page is rendered for display to the user.

S105: the client determines whether the page data of the next page needs to be acquired based on the new field value corresponding to the page field.

As an example, after the client receives the new field value corresponding to the paging field issued by the server, the client may determine whether to acquire the paging data of the next page according to the new field value corresponding to the paging field. Specifically, when the field value corresponding to the paging field returned by the client receives the server is a preset second character for representing the last page of data, the client can determine that the current page of paging data requested by the client from the server is the last page of data in the information stream data, and at this time, the client can end to acquire the paging data. When the field value corresponding to the paging field returned by the client is not the preset second character, the client can determine that the paging data of the current page requested by the client from the server is not the last page data in the information stream data, that is, the paging data of the current page still has the paging data of the next page, and at this time, the client can continue to request the paging data of the next page by sending the new field value to the server.

As an example, in a specific implementation process, S105 may include: the client determines whether a new field value corresponding to the paging field is a preset second character, wherein the preset second character is used for representing the last page of data; if the client determines that the new field value is not the preset second character, determining that the paging data of the next page needs to be acquired, and sending a new data acquisition request for requesting to issue the paging data of the next page to the server by the client, wherein the new data acquisition request carries the new field value corresponding to the paging field; the client receives a new request response sent by the server, wherein the new request response comprises the following steps: the page data of the next page and the updated field value corresponding to the page field. And/or if the client determines that the new field value is the preset second character, determining that the server is not required to issue the paging data of the next page, and outputting preset reminding information for reminding that the paging data of the current page is the last page data.

Specifically, after the client receives the new field value corresponding to the paging field sent by the server, the server will determine whether the new field value returned by the server is a preset second character for representing the last page of data. Then, if the client determines that the new field value is the preset second character, the client determines that the paging data of the current page is the last page data, and at this time, the client can stop acquiring the paging data without requesting the server to issue the paging data of the next page, and output the preset reminding information to prompt the user that the paging data of the current page is the last page data, i.e. prompt the user that the last page has been recorded. If the client determines that the new field value is not the preset second character, the client may determine that the next page of data is still available after the current page, and then the client may transmit the new field value returned by the server to the server as the request parameter, at this time, the server may receive the new field value corresponding to the paging field sent by the client, and then use the new field value as the original field value, and restart to execute step S102 until the paging data of the current page is the last page of data.

Therefore, in the process that the server and the client perform the paging data interaction through the paging field configured based on the general paging protocol, the data acquisition request sent to the server by the client needs to carry the paging field set according to the general paging protocol and the field value corresponding to the paging field, and the request response sent to the client by the server needs to carry the paging data requested by the client and the field value corresponding to the paging field to be sent to the client, so that the client can acquire the paging data of the next page. In general, then, in the process of the server and the client performing the paging data interaction through the paging field configured based on the above-mentioned general paging protocol, there may be the following four interaction processes:

(1) When the paging data of the current page requested by the client to the server is the first page data, the client can default fill in the field value corresponding to the paging field as a preset first character.

(2) When the paging data of the current page requested by the client to the server is other page data than the first page data, the client may retransmit the preset third character, which is issued by the server and is used for representing other page data except the first page data and the last page data, to the server, that is, the field value of the paging field received by the client when the client requests the previous page data of the other page data.

(3) When the field value corresponding to the paging field returned by the client side is a preset second character, the paging data of the current page requested by the client side to the server side is indicated to be the last page data in the information stream data.

(4) When the field value corresponding to the paging field returned by the client side is not the preset second character, the paging data of the current page requested by the client side to the server side is indicated not to be the last page data in the information stream data. At this point, the client may continue to request the next page of data.

It should be understood that, although terms such as original and new may be used to describe the field values of the paging field transmitted by the server and the client during the data acquisition process in the embodiments of the present invention, these terms are only used to distinguish the same type of information as the field values of the paging field from each other, without departing from the scope of the present application, the original field value corresponding to the paging field refers to the field value sent by the client to the server, and the new field value corresponding to the paging field refers to the field value sent by the server to the client. Specifically, in the same interaction process, the new field value corresponding to the paging field returned to the client by the server is different from the original field value corresponding to the paging field sent to the server by the client. However, in the two adjacent interactions, the original field value transmitted to the server by the client in the last interaction may be the new field value returned to the client by the server in the previous interaction. For example, if the paging data of the current page acquired by the client in the previous interaction process still has the paging data of the next page, the client may perform the next interaction process with the server to acquire the paging data of the next page, and then in the next interaction process, the client may send the new field value issued by the server in the previous interaction process to the server again as the new original field value.

As can be seen from the above, in the process that the server and the client perform the paging data interaction through the paging field configured based on the general paging protocol, the meaning of the paging field is almost transparent for the client, when the client needs to acquire the paging data, the client only needs to send the default preset first character to the server as the field value corresponding to the paging field, or the client only needs to send the field value corresponding to the paging field issued by the server in the process of the data request again to the server in the next data request, so as to acquire the corresponding next page data. Therefore, the intervention of the client on the paging mechanism can be reduced, and then the core logic of the paging mechanism can be controlled by the server under the cooperation of the client, so that the server can switch the specific paging method without perception of the client, and further, the flexibility of the service can be realized. In addition, the server and the client are realized through the paging fields which are almost transparent to the client in the process of paging data interaction, and the server can configure the paging mode according to the service and set the corresponding preset paging strategy, so that the paging mechanism controlled by the server can be compatible with various paging modes, such as a compatible page number paging mode and a displacement paging mode.

Each step in the above-described data acquisition method is described below with specific examples.

In another embodiment of the present invention, in order to obtain the paging data of the current page requested by the client and determine the new field value corresponding to the paging field that needs to be issued to the client, the step S102 may include the following steps A1 to A2:

step A1: the server acquires a sorting field, a paging record number and a paging mode from preset paging configuration logic as paging configuration information;

step A2: the server end determines the paging data of the current page and the new field value corresponding to the paging field based on the ordering field, the paging record number, the paging mode and the original field value.

In practical application, the preconfigured paging configuration logic may be stored in a local storage space of the server side, or may be remotely stored in a cloud storage space. Here, the memory location where the preconfigured page configuration logic is located is not specifically limited in the embodiment of the present invention.

The following describes how the server obtains the paging data of the current page requested by the client and determines the new field value corresponding to the paging field to be issued to the client, taking the server as an example to configure the paging mode into the page number paging mode or the displacement paging mode.

In the implementation process, the step A2 may be implemented in two ways according to the paging mode, but is not limited to the following two ways.

In the first implementation manner, if the paging mode obtained by the server from the preset paging configuration logic is a page number paging mode, in a specific implementation process, the step A2 may include the following steps B1 to B3:

step B1: the server end determines the current page code number corresponding to the paging data of the current page based on the original field value corresponding to the paging field;

step B2: the server end determines the paging data of the current page based on the ordering field, the paging record number and the current page code number;

step B3: the server end determines a new field value corresponding to the paging field based on the current number of page codes and the number of paging records.

First, a description will be given of how the server determines the current page number corresponding to the page data of the current page when the paging mode is the page paging mode.

In other embodiments of the present invention, the following three cases may exist in the above step B1, but are not limited to the following cases, according to whether the paging data of the current page requested to be issued by the client is the first page data:

in the first case, when the paging data of the current page requested to be sent by the client is the first page data, the step B1 may include: the method comprises the steps that a server determines whether an original field value corresponding to a paging field is a preset first character or not, wherein the preset first character is used for representing first page data; if the original field value is determined to be the preset first character, the preset initial page code number is used as the current page code number corresponding to the paging data of the current page.

Specifically, when the server determines, based on the general paging protocol, that the original field value corresponding to the paging field sent by the client is the preset first character for representing the first page data, the server may determine that the paging data of the current page requested to be sent by the client is the first page data, so that the server may use the preset initial page code number as the page number corresponding to the paging data of the current page requested to be sent by the client.

Illustratively, the preset starting page number is different according to the preset page number counting mode. For example, when a natural number, i.e., 0, 1, 2, 3, etc., is used as the page code number, the preset start page code number may be 0; when a positive integer, i.e., 1, 2, 3, 4, etc., is used as the number of page codes, the preset starting number of page codes may be 1. Of course, the number of the preset initial page code may be other characters, which may be set by those skilled in the art according to practical application, and the embodiment of the present invention is not limited herein.

In the second case, when the paging data of the current page requested to be issued by the client is not the first page data, the step B1 may include: the method comprises the steps that a server determines whether an original field value corresponding to a paging field is a preset first character or not, wherein the preset first character is used for representing first page data; if the original field value is determined not to be the preset first character, the server inquires the target page code number corresponding to the original field value according to the corresponding relation between the pre-stored field value and the page number, and takes the target page code number as the current page code number.

Specifically, the corresponding relationship between the field value and the page number is pre-stored in the server, when the server determines, based on the general paging protocol, that the original field value corresponding to the paging field sent by the client is not the preset first character for representing the first page data, the server may determine that the paging data of the current page requested to be sent by the client is other page data except the first page data, and then, according to the corresponding relationship, the server may determine the target page number corresponding to the original field value as the current page number corresponding to the paging data of the current page requested to be sent by the client.

For example, the above-mentioned correspondence may be stored in the server in the form of a table, and then, as shown in table 1, the original field value corresponding to the paging field, i.e. 1, corresponds to the number of page codes of 2, that is, the number of current page codes corresponding to the paging data of the current page requested to be issued by the client is 2, that is, the client requests the server to issue the second page data.

Field value	Page code number
		0	1
1	2
		2	3
...	...
		N	N+1

TABLE 1

Of course, the corresponding relationship between the field value and the page number may be other types and other values, which can be set by those skilled in the art, and the present invention is not limited in particular.

In the third case, taking the case that the page number is implemented by a positive integer counted from 1 and the field value is implemented by a positive integer as an example, when the page data of the current page requested to be issued by the client is not the first page data, the step B1 may include: the method comprises the steps that a server determines whether an original field value corresponding to a paging field is a preset first character or not, wherein the preset first character is used for representing first page data; if the original field value is determined not to be the preset first character, the original field value is used as the current page code number corresponding to the paging data of the current page.

Specifically, when the server determines, based on the above general paging protocol, that the original field value corresponding to the paging field sent by the client is not the preset first character for representing the first page data, then the server may determine that the paging data of the current page requested to be sent by the client is other page data except the first page data, then, since the number of page codes is implemented by a positive integer counted from 1, and the field value is also implemented by a positive integer, then the server may directly use the original field value as the number of current page codes corresponding to the paging data of the current page.

Of course, other cases may exist in addition to the three listed cases, to determine the number of current page codes corresponding to the paging data of the current page, for example, the first case and the second/third case are combined, and the embodiment of the present invention is not limited specifically herein.

Next, description is made on how the server obtains the page data of the current page when the paging mode is the page number paging mode.

As an example, in a specific implementation process, the step B2 may include: the server orders the pre-stored information stream data according to the ordering field to obtain ordered information stream data; determining a first record index corresponding to the paging data of the current page based on the paging record number and the current page code number; starting from the record pointed by the first record index in the sorted information stream data, and reading the record by taking the number of the inquired records as the target number to obtain the paging data of the current page.

In practical application, taking the specific page number as a positive integer counted from 1 and the recording index as an example counted from 0, then subtracting 1 from the current page number to obtain a difference value, and then multiplying the difference value by the paging recording number to obtain a product as the first recording index of the current page, that is, the first recording index= (the current page number-1 corresponding to the current page) of the current page.

Finally, the description is made on how the server determines the new field value corresponding to the paging field when the paging mode is the page paging mode.

In a specific implementation process, the step B3 may include the following steps C1 to C3:

step C1: the method comprises the steps that a server side obtains the total record number of pre-stored information stream data;

step C2: the server determines the total page number corresponding to the information stream data based on the total record number and the paging record number;

as an example, in a specific implementation process, the step C2 may include: the server determines whether the remainder obtained by dividing the total record number by the paging record number is equal to 0; if yes, dividing the total record number by the paging record number to obtain a quotient serving as the total page number; otherwise, the sum of the quotient obtained by dividing the total record number by the paging record number and 1 is taken as the total page number.

Specifically, when the total record number can divide the number of page records entirely, the total page number=total record number/page record number; when the total record number cannot divide the number of page records entirely, the total number of pages=total record number/number of page records+1.

It should be noted that, when the service corresponding to the information flow data provided by the server is a service with infrequent deletion and update operations, in order to save system resources, the server does not need to recalculate the total number of pages corresponding to the information flow data when the client acquires the paging data corresponding to the information flow data of the service each time, but the server can determine the total number of pages corresponding to the pre-stored information flow data by the total number of records corresponding to the pre-stored information flow data and the number of paging records set in the paging configuration logic in advance only when the paging data of the current page acquired by the client is the first page data, and store the total number of pages, so that the server can directly read when the subsequent client acquires the paging data of the next page. When the service corresponding to the information stream data provided by the server is the service with frequent deletion and update operations, in order to avoid the problem that the total page number calculated in advance is inaccurate because of the deletion and update operations of the user on the information stream data, the server needs to recalculate the total page number corresponding to the information stream data when the client acquires the paging data corresponding to the information stream data of the service each time.

Step C3: the server determines a new field value based on the current number of pages and the total number of pages.

As an example, in a specific implementation process, the above step C3 may include the following steps D1 to D3:

step D1: the service terminal determines whether the paging data of the current page is the last page data or not based on the current page code number and the total page number;

step D2: the server takes a preset second character as a new field value corresponding to the paging field;

wherein, preset the second character to be used for representing last page data.

Step D3: the server takes the character determined based on the current page code number as a new field value corresponding to the paging field.

Specifically, if the server determines that the paging data of the current page requested to be sent by the client is the last page, the server may execute step D2 to determine, according to the general paging protocol, the preset second character for representing the last page data as the new field value corresponding to the paging field; if the server determines that the paging data of the current page requested to be sent by the client is other page data except the last page data, the server may execute step D3 to determine the character determined based on the current number of page codes as a new field value corresponding to the paging field.

As an example, when the specific number of pages is implemented with a positive integer counted from 1, then, in the implementation process, the step D1 may include: the server judges whether the current page number is equal to the total page number; if yes, determining the paging data of the current page as the last page data; otherwise, it is determined that the paging data of the current page is not the last page data.

As an example, when the field value of the paging field and the page number are both implemented with a positive integer counted from 1, the current page number differs from the next page number by 1, and then the step D3 may include: the server takes the sum of the current page code number and 1 as a new field value corresponding to the paging field.

As an example, in a specific implementation process, the step D3 may include: the server determines the sum of the current page code number and 1 as the next page code number; inquiring a target field value corresponding to the next page number according to the corresponding relation between the prestored page number and the field value; and taking the target field value as a new field value corresponding to the paging field.

For example, the above-mentioned correspondence may be stored in the server in the form of a table, and then, taking the current page code number as 2 as an example, the next page code number is 3, and then, as shown in table 1, the next page code number, i.e. 3, corresponds to a field value of 2, that is, the server will issue a new field value of 2 to the paging field of the client.

In a second implementation manner, if the acquired paging mode of the server from the preset paging configuration logic is a displacement paging mode, in a specific implementation process, the step A2 may include the following steps E1 to E4:

step E1: the server determines whether the original field value corresponding to the paging field is a preset first character;

wherein, the first character is preset for representing the first page data.

Step E2: the server acquires the paging data of the current page from the pre-stored information stream data according to the ordering field and the paging record number, and determines a new field value corresponding to the paging field;

step E3: the server end determines a displacement value corresponding to paging data of the current page based on an original field value corresponding to the paging field;

as an example, the server may directly use the original field value corresponding to the paging field as the displacement value corresponding to the paging data of the current page.

Step E4: and the server determines the paging data of the current page and the new field value corresponding to the paging field according to the ordering field, the displacement value and the paging record number.

Specifically, if the server determines that the original field value corresponding to the paging field is the preset first character, the server may determine that the paging data of the current page requested to be issued by the client is the first page data, and at this time, the server may execute step E2 without adding a displacement condition, directly obtain the paging data of the current page from the pre-stored information stream data through the ordering field and the number of paging records, and determine the new field value corresponding to the paging field. If the server determines that the original field value corresponding to the paging field is not the preset first character, the server may determine that the paging data of the current page requested to be issued by the client is other page data except the first page data, and then, in order to obtain the paging data, a displacement condition needs to be added, then, the server may execute steps E3 to E4, firstly, determine a displacement value corresponding to the paging data of the current page based on the original field value corresponding to the paging field, and then, according to the displacement value, the sorting field and the number of paging records, obtain the paging data of the current page from the prestored information stream data, and determine a new field value corresponding to the paging field.

First, how the server obtains the paging data of the current page and determines the new field value corresponding to the paging field when the paging mode is the page paging mode and the paging data of the current page requested by the client is the first page data is described.

In a specific implementation process, the step E2 may be implemented by the following steps F1 to F4:

step F1: the server determines the sum of the paging record number and 1 as the query record number;

step F2: the server orders the pre-stored information stream data according to the ordering field to obtain ordered information stream data;

step F3: the server starts from the first record in the sorted information stream data, and reads the record by taking the number of the inquired records as the target number to obtain inquired paging data;

step F4: the server determines the paging data of the current page based on the queried paging data and the query record number, and determines a new field value corresponding to the paging field.

Next, how the server obtains the page data of the current page and determines the new field value corresponding to the page field when the page data of the current page requested by the client is other page data than the first page data is the page paging mode.

In the implementation process, in order to realize that when the deleting operation is performed on the current page of the data, the data is paged or stabilized by the displacement paging mode, one record needs to be acquired, and then the step E4 can be implemented by the following steps G1 to G4:

step G1: the server determines the sum of the paging record number and 1 as the query record number;

step G2: the server orders the pre-stored information stream data according to the ordering field to obtain ordered information stream data;

step G3: the server starts from the record pointed by the displacement value in the sorted information stream data, and reads the record by taking the number of the inquired records as the target number to obtain inquired paging data;

step G4: the server determines the paging data of the current page based on the queried paging data and the query record number, and determines a new field value corresponding to the paging field.

In other embodiments of the present invention, the step F4 or the step G4 may be implemented by the following steps H1 to H3:

step H1: the server determines the actual record number corresponding to the queried paging data;

step H2: the server compares the actual record number with the query record number;

Step H3: and the server determines the paging data of the current page according to the comparison result and the queried paging data, and determines a new field value corresponding to the paging field.

In a specific implementation, the above step H3 may exist, but is not limited to, the following two cases according to the comparison result.

In the first case, the step H3 may include: if the actual record number is equal to the query record number, the server takes other records except the last record in the queried paging data as the paging data of the current page; and taking the field value corresponding to the sorting field in the last record as a new field value corresponding to the paging field.

Specifically, in order to avoid the problem that the page is unstable due to deleting the last record in the page data of the current page by the user, when the actual record number corresponding to the page data queried by the server is equal to the query record number, that is, the sum of the page record number and 1, and the maximum record number that can be displayed by each page is the page record number, the server can determine that the next page data still exists after the page data of the current page requested to be issued by the client, at this time, the server can issue other records except the last record in the queried page data to the client as the page data of the current page, and issue the field value corresponding to the ordering field in the last record as the new field value corresponding to the page field to the client, so that the client resends the new field value to the server to request the server to issue the next page data.

For example, assume that the maximum number of records that can be displayed per page, i.e., the number of page records is 5, and that the page data queried by the server is sequentially record 1, record 2, record 3, record 4, record 5, and record 6. Thus, after the server sends record 1, record 2, record 3, record 4, and record 5 to the client, the user cannot see "record 6" because the server does not send "record 6" to the client, and thus the user cannot delete "record 6". Next, even if the user performs the deletion operation on "record 5" in "record 1, record 2, record 3, record 4, and record 5" displayed on the client, since the server side issues the field value corresponding to the sorting field in the last record, i.e., the "record 6", as the new field value corresponding to the paging field to the client side, when the client side requests the next page of data, the server side can query "record 6" according to the field value corresponding to the sorting field in "record 6", and further, the server side can obtain the paging data required by the client side from "record 6". Thus, the problem of unstable paging caused by deleting the last record in the paging data of the current page by the user can be avoided.

In the second case, the step H3 may include: if the actual record number is smaller than the query record number, the server takes all records in the queried paging data as the paging data of the current page; and taking a preset second character as a new field value corresponding to the paging field, wherein the preset second character is used for representing the last page of data.

Specifically, when the actual record count corresponding to the paging data queried by the server is smaller than the query record count, that is, the sum of the paging record count and 1, since the maximum record count that can be displayed by each page is the paging record count, the server can determine that there is no next page data after the paging data of the current page requested to be issued by the client, that is, the server can determine that the paging data of the current page requested to be issued by the client is the last page data, at this time, the server can issue all records in the queried paging data as the paging data of the current page to the client, and issue a preset second character for representing the last page data as a new field value corresponding to the paging field to the client, so that the client knows that the paging data of the current page requested by the client is the last page data, and further, the client finishes requesting to issue the paging data.

Thus, the interactive process of the client and the server for acquiring the paging data based on the paging field is completed.

As can be seen from the foregoing, in the data acquisition method provided by the embodiment of the present invention, after the server receives the data acquisition request sent by the client and used for requesting to issue the paging data of the current page, the server may acquire the paging data of the current page required by the client based on the original field value corresponding to the paging field carried in the data acquisition request and the pre-stored paging configuration information, determine the new field value corresponding to the paging field to be issued to the client, and then send the paging data of the current page and the new field value corresponding to the paging field to the client, so that the client can perform subsequent processing on the paging data of the current page and the new field value corresponding to the paging field. In this way, in the process of obtaining the paging data, the paging configuration information is completely controlled by the server, and the field value of the paging field can be issued to the client by the server, so that the server can flexibly configure the paging configuration information according to the service, such as the paging mode, and further, the server can flexibly switch from one paging mode to another paging mode.

Based on the same inventive concept, an embodiment of the present invention provides a data acquisition method, and fig. 2A is a second schematic flow chart of the data acquisition method in the embodiment of the present invention, as shown in fig. 2A, after S104, the data acquisition method may include:

s201: the client determines whether a new field value corresponding to the paging field is a preset second character;

the second character is preset and used for representing the last page of data;

specifically, after the client receives the new field value corresponding to the paging field issued by the server, the server executes S201 to determine whether the new field value returned by the server is a preset second character for representing the last page of data. After the client executes S201, if the client determines that the new field value corresponding to the paging field returned by the server is not the preset second character, which indicates that there is paging data of the next page, at this time, the client determines that the paging data of the next page needs to be acquired, S202-S203 may be executed, and the new field value is added as the original field value in the data acquisition request and is resent to the server, so as to request the server to issue the paging data of the next page and the updated field value; after the client executes S201, if the client determines that the new field value corresponding to the paging field returned by the server is the preset second character, which indicates that the paging data of the next page is not available, at this time, the client does not need to request the server to issue the paging data of the next page, and S204 may be executed to output the reminding information, so as to remind the user that the paging data of the next page is not available.

S202: the client sends a new data acquisition request for requesting to issue paging data of the next page to the server, wherein the new data acquisition request carries a new field value corresponding to the paging field;

s203: the server side sends a new request response to the client side, wherein the new request response comprises the following steps: the paging data of the next page and the updated field value corresponding to the paging field;

specifically, if the client determines that the new field value is not the preset second character, the client may determine that the next page of data is still after the current page, and then the client may transmit the new field value returned by the server to the server as a request parameter to request the server to issue the paging data of the next page and the updated field value corresponding to the paging field. Next, after the server receives the new field value corresponding to the paging field sent by the client, the server will use the new field value as the original field value, and continue to execute step S102 to determine the paging data of the next page and the field value corresponding to the paging field, then execute step S203 to send the paging data of the next page and the updated field value corresponding to the paging field to the client, finally, the client can use the updated field value as the new field value, continue to execute step S104, and continue to execute step S201 after step S104 until the server returns the last page of data to the client.

S204: and the client outputs reminding information.

Here, the reminder information is used to prompt the user that the paging data of the current page is the last page data.

The data acquisition method proposed in the embodiment of the present invention will be described below with specific examples.

Illustratively, the content in the generic paging protocol includes: the paging field is denoted as offset,0 represents the first page of data, and-1 represents the last page of data, and then, referring to fig. 2B, the interaction process between the client and the server for implementing data acquisition through the paging field may be briefly described as follows:

step 1, the client needs to request the server to issue paging data of the first page, and the client can send a data acquisition request carrying offset=0 to the server;

step2, after receiving the data acquisition request, the server acquires the sorting field, the number of the paging records (recorded as pageSize) and the adopted paging mode of the scene from the paging configuration logic. If the paging mode is a page number paging mode, the flow is switched to Step3.1-Step3.5; if the paging mode is a displacement paging mode, the flow is switched to Step4.1-Step4.5;

step3.1, the server judges whether the offset transmitted by the client is equal to 0, if the offset is equal to 0, the server determines that the page number of the paging data requested by the client is equal to the preset initial page number used for representing the first page, and if the offset is not equal to 0, the server determines that the page number of the paging data requested by the client is equal to the offset;

Step3.2, the server obtains page size record data corresponding to the page number from the pre-stored information stream data based on the ordering field according to the page number obtained by step3.1, and obtains the page data requested by the client;

step3.3, the server calculates the total page number according to the pageSize obtained from the paging configuration logic and the total record number of the information stream data;

step3.4, the server side checks whether the page number is equal to the total page number calculated by step3.3 according to the page number obtained by step3.1, if yes, the page data offset= -1 of the next page is not available, otherwise, the page data of the next page is available, and the offset = the page number of the next page, namely, the page number obtained by step3.1 is +1;

step3.5, the server returns the paging data acquired by step3.2 and the field value corresponding to the offset calculated by step3.4 to the client;

step4.1, the server judges whether the offset transmitted by the client is equal to 0, if the offset is equal to 0, determines that the paging data requested by the client is the first page data, and if the offset is not equal to 0, the displacement condition is required to be added, and the displacement value can be the offset;

step4.2, according to the displacement value of step4.1, acquiring pages+1 records from the pre-stored information stream data based on the ordering field, and obtaining the queried paging data;

Step4.3, calculating whether the actual record number of the queried paging data acquired by Step4.2 is smaller than pagesize+1 (i.e. the query record number), if so, indicating that no paging data of the next page exists, and if not, performing offset= -1, otherwise performing offset = the value of the ordering field in the pagesize+1 record, namely performing offset on the new field value which is equal to the value of the ordering field (acquired by Step 2) in the last record in the queried paging data;

step4.4, if the actual record number of the queried paging data acquired by step4.2 is equal to the pagesize+1, the paging data returned to the client by the server is a previous pageSize strip record, otherwise, all records of the query are returned;

step4.5, the server returns the field value corresponding to the offset calculated by step4.3 and the paging data determined by step4.4 to the client;

step5, after receiving a request response returned by the server, the client renders the paging data returned by the server into a page component to be displayed to a user, then judges whether offset returned by the server is equal to-1, if yes, the flow enters Step6, and if not, the flow enters Step7;

step6, the client outputs reminding information on the page to prompt the user that the last record is reached;

Step7, the client requests paging data of the next page, and transmits a field value corresponding to the offset returned by the offset=server as a parameter to the server. Then, the flow goes to the server Step2.

As can be seen from the above, in the process that the server and the client perform the paging data interaction through the paging field configured based on the general paging protocol, the meaning of the paging field is almost transparent for the client, when the client needs to acquire the paging data, the client only needs to send the default preset first character to the server as the field value corresponding to the paging field, or the client only needs to send the field value corresponding to the paging field issued by the server in the process of the data request again to the server in the next data request, so as to acquire the corresponding next page data. Therefore, the intervention of the client on the paging mechanism can be reduced, and the core logic of the paging mechanism can be controlled by the server under the cooperation of the client, so that the server can switch the specific paging method without perception of the client, and further, the flexibility of the service can be realized.

Based on the same inventive concept, an embodiment of the present invention provides a data acquisition method, and fig. 3 is a schematic flow chart of the data acquisition method in the embodiment of the present invention, and as shown in fig. 3, the data acquisition method may include:

s301: the server obtains modification data aiming at least one of a sorting field, a paging record number and a paging mode contained in preset paging configuration information;

specifically, in the process that the server and the client perform the paging data interaction through the paging field configured based on the above general paging protocol, the meaning of the paging field is almost transparent for the client, so when the service scene changes, the server may directly modify the pre-stored paging configuration information, for example, switch the paging mode in the pre-stored paging configuration information from the paging mode to the displacement paging mode, switch the sorting field in the pre-stored paging configuration information from the sorting field 1 to the sorting field 2, switch the number of the paging records in the pre-stored paging configuration information from the first value to the second value, and so on, where the server may obtain the modified data corresponding to at least one of the sorting field, the number of the paging records, and the paging mode.

For example, assume that the information stream data is a merchandise display list including a plurality of merchandise records, the server performs paging processing on the information stream data, and the server initially arranges the plurality of merchandise records in reverse order according to the creation time of the merchandise, where the ordering field set by the server is the creation time of the merchandise records. Next, when the service needs to change the scene into the arrangement according to the modification time of the commodity, the service is the core logic for controlling the paging mechanism by the server, so that the service only needs to modify the ordering field of the commodity record from the creation time to the modification time in the pre-stored paging configuration information, and the whole ordering logic is completed, thereby the service side flexibly switches the ordering field from the creation time to the modification time, and the client does not need to perform any modification, so that the service side is not aware.

S302: the server modifies the paging configuration information based on the modification data to obtain modified paging configuration information;

s303: the server receives a data acquisition request sent by the client, wherein the data acquisition request carries a primary field value corresponding to a paging field, and the primary field value is a preset first character for representing data of a first page;

S304: the server side responds to the data acquisition request, determines the paging data of the current page based on the original field value corresponding to the paging field and the modified paging configuration information, and determines a new field value corresponding to the paging field;

s305: the server sends a request response to the client, wherein the request response comprises: paging data of the current page and a new field value corresponding to the paging field.

Specifically, in the process that the server and the client interact with each other through the paging field configured based on the general paging protocol, after the server modifies the paging configuration information, in order to avoid unstable paging, the client needs to acquire the first page data corresponding to the information stream data again. Specifically, when the client needs to acquire paging data, the client only needs to send a default preset first character to the server as a field value corresponding to the paging field, so as to acquire the first page data, or the client only needs to send the field value corresponding to the paging field issued by the server in the process of the data request, and when the next data request is performed, the client resends the field value to the server so as to acquire the corresponding next page data. Therefore, under the cooperation of the client, the core logic of the paging mechanism can be controlled by the server, so that the server can switch the specific paging method without perception by the client, and further, the flexibility of the service can be realized.

In another embodiment of the present invention, when the server issues the paging data of the current page to the client and the new field value of the paging field issued by the server to the client is not the preset second character for representing the last page of data, at this time, the client may determine that there is still the next page of data after the received paging data of the current page, so the client may further resend the new field value of the paging field issued by the server to request the server to issue the paging data of the next page, and in the implementation process, after S305, if the new field value is not the preset second character for representing the last page of data, the method may further include: the server receives a new data acquisition request sent by the client, wherein the data acquisition request carries a new field value corresponding to the paging field; responding to a new data acquisition request, acquiring paging data of the next page based on a new field value corresponding to a paging field and modified paging configuration information, and determining an updated field value corresponding to the paging field; the server side sends a new request response to the client side, wherein the new request response comprises the following steps: the page data of the next page and the updated field value corresponding to the page field.

According to the above, the paging mechanism is controlled by the server, when the service scene changes and needs to change the paging configuration information such as the ordering field, the number of the paging records, the paging mode and the like, the client only needs to modify the pre-stored paging configuration information at the server, and the client does not need to modify any of the pre-stored paging configuration information.

Based on the same inventive concept, as an implementation of the above method, the embodiment of the present invention provides a data acquisition device, which may be applied to a server in practical application.

Fig. 4 is a schematic structural diagram of a data acquisition device according to an embodiment of the present invention, and referring to fig. 4, the device 40 may include: a receiving unit 401, configured to receive a data acquisition request sent by a client, where the data acquisition request carries an original field value corresponding to a paging field; a determining unit 402, configured to determine, based on the original field value and preset paging configuration information, paging data of a current page and a new field value corresponding to a paging field; a sending unit 403, configured to send a request response to the client, where the request response includes: paging data of the current page and a new field value.

In the embodiment of the invention, a determining unit is used for acquiring an ordering field, a paging record number and a paging mode from preset paging configuration logic as paging configuration information; based on the ordering field, the number of page records, the paging mode, and the original field value, the paging data of the current page and the new field value are determined.

In the embodiment of the invention, the determining unit is used for determining the current page number based on the original field value if the paging mode is a page number paging mode; determining paging data of the current page based on the ordering field, the paging record number and the current page code number; a new field value is determined based on the current number of page codes and the number of page records.

In the embodiment of the invention, a determining unit is used for determining whether the original field value is a preset first character, wherein the preset first character is used for representing first page data; if the original field value is determined to be the preset first character, the preset initial page code number is used as the current page code number.

In the embodiment of the invention, the determining unit is configured to query, if it is determined that the original field value is not the preset first character, a target page number corresponding to the original field value according to a correspondence between the pre-stored field value and the page number, and take the target page number as the current page number.

In the embodiment of the present invention, the determining unit is configured to, if it is determined that the original field value is not the preset first character, use the original field value as the current page code number corresponding to the paging data of the current page.

In the embodiment of the invention, a determining unit is used for acquiring the total record number of the pre-stored information stream data; determining the total page number corresponding to the information stream data based on the total record number and the paging record number; a new field value is determined based on the current number of pages and the total number of pages.

In the embodiment of the invention, a determining unit is used for determining whether the remainder obtained by dividing the total record number by the paging record number is equal to 0; if yes, dividing the total record number by the paging record number to obtain a quotient serving as the total page number; otherwise, the sum of the quotient obtained by dividing the total record number by the paging record number and 1 is taken as the total page number.

In the embodiment of the invention, a determining unit is used for determining whether paging data of a current page is data of a last page or not based on the number of codes of the current page and the total number of pages; if yes, taking a preset second character as a new field value, wherein the preset second character is used for representing the last page of data; otherwise, the character determined based on the current number of page codes is taken as a new field value.
