With continued reference to FIG. 2, a flow 200 of one embodiment of a data request method according to the present disclosure is shown. The data request method is applied to any server and comprises the following steps:

step 210, in response to receiving a page data acquisition request sent by a terminal, performing screen splitting operation on the page data based on the screen size of the terminal to obtain a sub-page data sequence.

The page data is composed of a plurality of node data, and each node data represents a data presentation. The execution body may perform node classification on the page data to obtain a node data sequence corresponding to the page data. Each node data has a uniquely determined node identifier id, and each node data has an attribute of interface display height, which represents height information of the node data when the node data is rendered in a terminal interface. Therefore, each node data is arranged in a form of a floor according to the height information of the node data to form page data.

In this step, when the user wants to view a certain page at the terminal, the terminal may send an acquisition request for the page data to the execution main body according to the operation of the user. The execution main body can receive a page data acquisition request sent by a terminal, acquire the screen size of the terminal sending the request, such as the height information of the screen, after receiving the page data acquisition request, and then perform screen splitting operation on the page data according to the acquired screen size of the terminal and the height information of the node data of the page data to obtain a sub-page data sequence corresponding to the page data. The execution main body stores the obtained sub-page data sequence into an overall database, which may be a cache database in a server, and is used for storing the sub-page data sequence corresponding to the page data.

The sub-page data sequence obtained after the page data is subjected to the screen splitting operation comprises at least one sub-page data, the sub-page data comprises node data corresponding to the page data, and the sum of the heights of the node data in each sub-page data is equal to the screen size of the terminal.

As a specific example, the execution body performs node classification on the page data to obtain a node data sequence, where each node data has certain height information. And after the execution main body obtains the screen size of the terminal, traversing the node data sequence, taking out each node data according to the sequence of the node data in the node data sequence, and superposing the height information by an increasing method according to the height information of the node data. And comparing the superposition height of the N pieces of node data with the screen size, and if the superposition height is equal to the screen size, taking the N pieces of node data as first sub-page data and storing the first sub-page data into the sub-page data sequence. Or if the stacking height is smaller than the screen size but the stacking height of the N +1 node data is larger than the screen size, the extracted N node data is taken as the first sub-page data and stored in the sub-page data sequence. And continuously traversing the node data sequence, continuously comparing the stacking height and the screen size of the taken node data, determining the node data contained in the second sub-page data, storing the node data into the sub-page data sequence, and repeating the steps to obtain the sub-page data sequence, wherein each sub-page data is loaded with the node data corresponding to the page data.

Step 220, sending the sub-page data with the preset number in the sub-page data sequence to the terminal.

In this step, after the execution main body obtains the sub-page data sequence, the sub-page data of the preset number in the sub-page data sequence in the whole database is stored in the cache database corresponding to the terminal according to the sequence of the sub-page data sequence, and the sub-page data of the preset number in the cache database is sent to the terminal. At this time, the sub-page data in the cache database corresponds to the sub-page data received by the terminal one by one. The execution main body may send two sub-page data or three sub-page data, which is not specifically limited in this application.

As a specific example, the execution main body receives a page data acquisition request sent by a terminal, stores first sub-page data and second sub-page data in a sub-page data sequence into a cache database corresponding to the terminal according to the sequence of the sub-page data sequence, and then sends two sub-page data in the cache database to the terminal, so that the terminal can analyze and render the received two sub-page data and present the two sub-page data to a user.

With continuing reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the data request method according to the present embodiment. In the application scenario of fig. 3, the server 350 performs node classification on the page data to obtain a node data sequence, where the node data sequence includes node data 310, node data 320, node data 330, node data 340, and other node data, and the node data 310, the node data 320, the node data 330, the node data 340, and other node data are sorted in the form of a floor to form page data. After receiving the page data acquisition request sent by the terminal 360, the server 350 acquires the screen size of the terminal 360, and then performs screen splitting operation on the page data according to the screen size and the height information of each node data to obtain a sub-page data sequence corresponding to the page data. If the sum of the height information of the node data 310, the node data 320, the node data 330, and the node data 340 is equal to the screen size, the node data 310, the node data 320, the node data 330, and the node data 340 are treated as the first sub-page data. The following nodes in the node data sequence form second sub-page data, third sub-page data and the like in the same way, and the first sub-page data, the second sub-page data and the third sub-page data form a sub-page data sequence. The server 350 sends the first sub-page data and the second sub-page data in the sub-page data sequence to the terminal 360, and the terminal 360 analyzes and renders the received first sub-page data and second sub-page data, and presents the first sub-page data to the user.

According to the data request method provided by the embodiment of the disclosure, in response to a received page data acquisition request sent by a terminal, the execution main body performs screen splitting operation on the page data according to the acquired screen size to obtain a sub-page data sequence including at least one sub-page data, and sends a preset number of sub-page data in the sub-page data sequence to the terminal. The page data is divided into a plurality of sub-page data, and the sub-page data with the preset number is sent to the terminal, so that the situation that all the page data is sent to the terminal is avoided, unnecessary page data is sent to the terminal is avoided, the terminal is prevented from processing the unnecessary page data, and the flow consumption of a user is reduced.

With further reference to fig. 4, fig. 4 illustrates a flow 400 of yet another embodiment of a data request method. The flow 400 of the data requesting method may further include the following steps:

step 410, in response to receiving a page data acquisition request sent by a terminal, performing screen splitting operation on the page data based on the screen size of the terminal to obtain a sub-page data sequence.

In this step, step 410 is the same as step 210 in the embodiment shown in fig. 2, and is not described herein again.

And step 420, sending the sub-page data with the preset number in the sub-page data sequence to the terminal.

In this step, step 420 is the same as step 220 in the embodiment shown in fig. 2, and is not described herein again.

Step 430, in response to determining that the terminal requests the remaining data in the sub-page data sequence that is not sent to the terminal, sending the unsent sub-page data adjacent to the sent sub-page data in the sub-page data sequence to the terminal.

In this step, after the execution main body sends the sub-page data of the preset number in the sub-page data sequence to the terminal, the terminal analyzes and renders the received sub-page data, presents the rendered sub-page data to a user, when the user is interested in the data, the data presented by the terminal is operated to request the rest data, at the moment, the execution main body determines that the terminal requests the rest data which is not sent to the terminal in the sub-page data sequence, determines the sub-page data sent to the terminal according to the sub-page data in the cache database, then storing unsent sub-page data adjacent to the transmitted sub-page data in the sub-page data sequence in the whole database into a cache database, and the sub-page data which is not sent in the cache database is sent to the terminal, and after the terminal receives the sub-page data, the received sub-page data is analyzed and rendered. At this time, the unsent sub-page data adjacent to the sent sub-page data may be one sub-page data or may be multiple sub-page data, which is not specifically limited in this application.

As a specific example, the execution main body determines that the terminal requests the remaining data that is not sent to the terminal in the sub-page data sequence, determines the sub-page data that is sent to the terminal according to the sub-page data in the cache database, then stores the next sub-page data adjacent to the sub-page data that is sent to the terminal in the sub-page data sequence in the entire database into the cache database, and sends the next sub-page data adjacent to the sub-page data that is sent to the terminal in the cache database to the terminal.

In this embodiment, when the execution main body determines that the terminal requests the remaining data that is not sent to the terminal in the sub-page data sequence, the unsent sub-page data is sent to the terminal, so that unnecessary data is prevented from being sent to the terminal when the user is not interested in the data, unnecessary operations performed by the terminal are reduced, and unnecessary data requests and resource waste are prevented.

In some optional implementation manners of this embodiment, in step 430 in fig. 4, in response to determining that the terminal requests the remaining data that is not sent to the terminal in the sub-page data sequence, sending unsent sub-page data adjacent to the sent sub-page data in the sub-page data sequence to the terminal, may be implemented by: and in response to receiving a second request sent by the terminal for the sub-page data sequence, sending unsent sub-page data adjacent to the sub-page data sent to the terminal in the sub-page data sequence to the terminal.

And the second request is that the terminal receives the downslide operation of the user on the currently displayed sub-page data, and the sliding distance of the downslide operation meets the preset condition. The preset condition may be determined according to a response speed of the server, for example, the preset condition may be that a sliding distance of the slide-down operation is 1/2 of the current screen size, or may be that a sliding distance of the slide-down operation is 2/3 of the current screen size, and the like, which is not specifically limited in this application.

In this step, the execution main body may receive a second request for the sub-page data sequence sent by the terminal, determine the sub-page data sent to the terminal according to the sub-page data in the cache database, and then send, to the terminal, the unsent sub-page data adjacent to the sub-page data sent to the terminal in the sub-page data sequence in the entire database based on the second request. For example, the next sub-page data adjacent to the sub-page data sent to the terminal in the sub-page data sequence in the entire database may be sent to the terminal, or a plurality of sub-page data adjacent to the sub-page data sent to the terminal in the sub-page data sequence in the entire database may be sent to the terminal.

After receiving the sub-page data sent by the execution main body, the terminal analyzes and renders the sub-page data, and presents the sub-page data to the user, and the user can operate the currently displayed sub-page data in the terminal, such as an upward sliding operation, a downward sliding operation and the like, and can also perform updating operations such as modification, query, deletion, addition and the like on the displayed sub-page data. The execution body executes further operations according to the user's operations.

As a specific example, when the terminal receives that the user performs a slide-down operation on currently displayed sub-page data, the terminal acquires a sliding distance of the slide-down operation and determines the sliding distance, such as 2/3 that determines whether the sliding distance is the current screen size, and when determining that the sliding distance is 2/3 of the current screen size, the terminal sends a second request for the sub-page data sequence to the execution main body. And after receiving a second request sent by the terminal, the execution main body determines sub-page data which is sent to the terminal according to the sub-page data in the cache database, and then sends next sub-page data which is adjacent to the sub-page data which is sent to the terminal in the sub-page data sequence in the whole database to the terminal.

As a specific example, when the terminal receives that the user performs a slide-down operation on the currently displayed sub-page data, the terminal obtains a sliding distance of the slide-down operation, and determines whether the sliding distance is 2/3 of the current screen size, and when it is determined that the sliding distance of the slide-down operation is not 2/3 of the current screen size, the terminal determines that the user is not interested in the currently displayed page data, and does not send a second request to the execution main body for requesting the remaining data in the sub-page data sequence that is not sent to the terminal.

As a specific example, when the terminal receives that the user performs the slide-up operation on the currently displayed sub-page data, the terminal determines that the currently displayed page data is not of interest to the user, and does not send a second request to the execution main body, the second request requesting the remaining data in the sub-page data sequence that is not sent to the terminal.

As a specific example, when the terminal detects that the currently displayed page data is not the received sub-page data, it indicates that the user exits from the display interface of the sub-page data, and the terminal determines that the user is not interested in the received sub-page data, and does not send a second request to the execution main body, where the second request requests the remaining data in the sub-page data sequence that is not sent to the terminal.

In this implementation, the terminal determines, through an operation of the user, whether the user is interested in the received sub-page data, and further determines whether to send a second request to the execution main body requesting for the remaining data that is not sent to the terminal in the sub-page data sequence, and the execution main body sends, to the terminal, the unsent sub-page data that is adjacent to the sent sub-page data only when receiving the second request, thereby further avoiding sending unnecessary data to the terminal, and also avoiding loading and processing of unnecessary data by the terminal.

In some optional implementation manners of this embodiment, in step 430 in fig. 4, in response to determining that the terminal requests the remaining data that is not sent to the terminal in the sub-page data sequence, sending, to the terminal, unsent sub-page data that is adjacent to the sent sub-page data in the sub-page data sequence, which may also be implemented by the following steps:

the method comprises the steps of responding to a received sliding operation sent by a terminal, and judging whether the sliding distance of the sliding operation meets a preset condition.

The preset condition may be determined according to a response speed of the server, for example, the preset condition may be that a sliding distance of the downslide operation is 1/2 of the current screen size, or the sliding distance of the downslide operation is 2/3 of the current screen size, and the like, which is not specifically limited in this application.

In this step, the terminal may receive a slide-down operation of the user on the currently displayed sub-page data, acquire the slide-down operation of the user, and send the slide-down operation to the execution main body. The execution main body receives the downslide operation sent by the terminal and determines whether the sliding distance of the downslide operation meets a preset condition, for example, whether the sliding distance of the downslide operation is 1/2 of the current screen size or 2/3 of the current screen size may be determined.

And secondly, responding to the fact that the sliding distance meets the preset condition, and sending unsent sub-page data which are adjacent to the sub-page data sent to the terminal in the sub-page data sequence to the terminal.

In this step, if the execution main body determines that the sliding distance of the sliding-down operation meets the preset condition, the sub-page data sent to the terminal is determined according to the sub-page data in the cache database, and then the unsent sub-page data adjacent to the sub-page data sent to the terminal in the sub-page data sequence in the entire database is sent to the terminal based on the second request. For example, the next sub-page data adjacent to the sub-page data sent to the terminal in the sub-page data sequence in the entire database may be sent to the terminal, or a plurality of sub-page data adjacent to the sub-page data sent to the terminal in the sub-page data sequence in the entire database may be sent to the terminal.

In this implementation manner, the execution main body sends unsent sub-page data adjacent to the sent sub-page data to the terminal only when it is determined that the sliding distance of the user's sliding down operation meets the preset condition, so as to further avoid sending unnecessary data to the terminal and avoid loading and processing unnecessary data by the terminal.

With further reference to fig. 5, fig. 5 illustrates a flow 500 of yet another embodiment of a data request method. The flow 500 of the data requesting method may further include the following steps:

step 510, in response to receiving an update request for currently displayed sub-page data sent by a terminal, updating sub-page data in a sub-page data sequence.

The update request may include a modification request, a query request, a deletion request, an addition request, or the like for the currently displayed sub-page data.

In this step, the terminal presents the received sub-page data to the user, may receive an update operation of the user on the currently displayed sub-page data, and then sends an update request for the currently displayed sub-page data to the execution main body based on the update operation of the user. The execution main body receives an update request sent by a terminal, the update request comprises data targeted by the operation of a user, and the execution main body updates sub-page data in a sub-page data sequence in the whole database according to the update request to obtain an updated sub-page data sequence.

As a specific example, the update request is a modification request, that is, the terminal receives a modification operation of the currently displayed sub-page data by the user, and then sends a modification request of the currently displayed sub-page data to the execution main body based on the modification operation by the user. The execution main body receives a modification request sent by a terminal, the modification request comprises data to be modified by a user, and the execution main body modifies sub-page data in a sub-page data sequence in the whole database according to the modification request to obtain an updated sub-page data sequence.

And step 520, responding to the completion of updating the sub-page data in the sub-page data sequence, and updating the sub-page data in the cache database.

And the sub-page data in the cache database is the sub-page data which is sent to the terminal in the sub-page data sequence.

In this step, the execution main body updates the sub-page data in the sub-page data sequence in the entire database according to the update request to obtain an updated sub-page data sequence, then determines the sub-page data that has been sent to the terminal according to the sub-page data in the cache database, and stores the sub-page data that has been sent to the terminal in the updated sub-page data sequence into the cache database according to the determination result to complete the update operation of the sub-page data in the cache database.

Step 530, in response to the completion of updating the sub-page data in the cache database, sending the updated sub-page data in the cache database to the terminal.

In this step, after storing the sub-page data that has been sent to the terminal in the updated sub-page data sequence into the cache database, the execution main body sends the updated sub-page data in the cache database to the terminal. And the terminal receives the updated sub-page data, analyzes and renders the received sub-page data, and presents the sub-page data to the user.

In the embodiment, the sub-page data in the whole database and the cache database are updated, so that the consistency of the data is ensured, the synchronization and the update of the data are realized, and the existence of dirty data is avoided.

In some optional implementations of this embodiment, when the update request is a delete request or an add request for currently displayed sub-page data, the data request method further includes the following steps: and recording the last node data in the last subpage data in the cache database as the marked node data.

In this step, the execution main body receives a deletion request or an addition request for currently displayed sub-page data sent by the terminal, and records the last node data in the cache database as the marked node data to determine the sub-page data sent to the terminal.

In step 520 in fig. 5, in response to that the updating of the sub-page data in the sub-page data sequence is completed, the sub-page data in the cache database is updated, which may also be implemented by the following steps:

and step one, in response to the completion of updating of the sub-page data in the sub-page data sequence, using the updated sub-page data containing the marking node data as target sub-page data.

In this step, the execution main body deletes or adds sub-page data in a sub-page data sequence in the entire database according to the received deletion request or addition request for the currently displayed sub-page data to obtain an updated sub-page data sequence, and then uses the sub-page data containing the marking node data in the updated sub-page data sequence as target sub-page data.

As a specific example, when a deletion request of a user for currently displayed sub-page data is received, the execution main body deletes corresponding data in the entire database according to the deletion request, and at this time, a node data sequence corresponding to the page data changes, so that the sub-page data in the entire database is updated according to the changed node data to obtain an updated sub-page data sequence, and then the sub-page data in the updated sub-page data sequence, which includes the marked node data, is used as target sub-page data.

And secondly, taking the target sub-page data in the updated sub-page data sequence and the updated sub-page data before the target sub-page data as the updated sub-page data in the cache database, and sending the updated sub-page data to the terminal.

In this step, after the execution main body determines the target sub-page data, the target sub-page data in the updated sub-page data sequence and the sub-page data before the target sub-page data are stored in the cache database to update the sub-page data in the cache database, then the updated sub-page data are sent to the terminal, and the terminal analyzes and renders the received sub-page data and presents the sub-page data to the user.

In the implementation mode, the sub-page data in the whole database and the cache database are deleted or added, and the updated sub-page data is sent to the terminal, so that the consistency of the data is ensured, the synchronization and the update of the data are realized, and the existence of dirty data is avoided.
