Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The scheme of the application can use page windows such as a browser, an APP and the like, an operation interface and the like which need to realize page loading at a user side, wherein the user side can be a terminal, a mobile side and the like. According to the scheme, when the page window receives the instruction for displaying the data, the cache data can be extracted from the cache database and displayed, so that the time for a user to wait for page display is saved. And meanwhile, acquiring source data corresponding to the page window, and determining whether to refresh the display page of the display window in time or not based on the source data and the cache data, so that the user can acquire the latest data information.
Referring to fig. 1, a flow chart of a method for implementing preloading of page data according to an embodiment of the present application is shown, where a specific process flow may include:
step S110, obtaining the cache data corresponding to each data interface of the page to be loaded from the cache database.
And step S120, generating and displaying an initial display page corresponding to the page to be loaded based on the cache data.
And the page to be loaded is provided with at least one data interface, and each data interface is used for receiving corresponding data to realize data interaction between the page to be loaded and a cache database or a network data source.
In the cache database, data information corresponding to each data interface loaded by each page when last opened is stored, or data information of a specific page, such as a fixed display screen protection image, a layout structure and the like, is prestored. And acquiring data information corresponding to each data interface of the page to be loaded, namely cache information, from the cache database.
And carrying out page data layout operations such as layout, rendering and the like on the page to be loaded by using the cache data corresponding to each data interface to obtain an initial display page. The initial display page is a page which is instantly displayed by a user when the page to be loaded is opened.
The user side opens the page to be loaded to display the source data acquired in real time through the internet, but in the process of acquiring the source data, the page to be loaded is always a blank page or a standby page of a specific animation page to be loaded, and the speed of acquiring the source data by the page to be loaded depends on the network speed of the user side. In the process, the waiting time for the user to view the data is increased, and the situation that the data cannot be loaded all the time due to page blocking can occur due to network problems, so that the use effect of the user is affected.
However, the acquisition of data in the cache database is a direct retrieval process and does not require waiting for network loading. Therefore, the scheme of the application firstly uses the cache data to generate the initial display page, reduces the time for waiting for data loading of a user, can update the initial display page based on the source data later, and can update the initial display page under the condition that the user does not operate the page during updating.
Step S130, obtaining source data corresponding to the page to be loaded, and determining a target display page corresponding to the initial display page based on the source data.
Specifically, the source data is data acquired in real time by the page to be loaded, and may be acquired through a network of a user side, or may be acquired from a specific data source of the page to be loaded. For example, the page to be loaded is a video client top page of the video platform, and the data information of the video client top page needs to be requested to a server of the video platform through a network, and generally the data information may include information such as a new play when the sky is shown, a hot play of the current month, a high-score recommended movie and the like, and the data information is the source data of the video client top page.
Based on the cache data and the source data, whether the page to be loaded needs to be refreshed currently or not can be determined, and therefore the page display data corresponding to the page to be loaded is consistent with the source data. In the embodiment of the application, due to the diversity of information required by the page to be loaded, or in order to distinguish different types of data information, a plurality of data interfaces exist in the page to be loaded, each data interface can acquire corresponding data information, the real-time performance of the information of the front page of the client is strong, and the source data and the cache data need to be compared, but if the source data and the cache data are not compared according to the corresponding relation between the source data and the data interfaces, the situation of data disorder and updating disorder code is likely to occur.
For example, the page to be loaded needs to display the data information of the two data interfaces a and B, if the information corresponding to the data interface a in the cache data is A, the information corresponding to the data interface B is B; the information corresponding to the data interface a in the source data is B, and the information corresponding to the data interface B is A. If the comparison is not performed according to the corresponding relation between the data interface and the source data and the cache data, the possible comparison result is that the cache data and the source data are the same, and page update is not needed for the initial display page. However, in practice, the data information of the two data interfaces are different, and the initial display page needs to be updated.
Therefore, in order to avoid the situation that page data is not updated timely or data is disordered and the like due to the fact that data interfaces do not compare according to the corresponding relation, the scheme of the application needs to compare the source data with the cache data one by one according to the corresponding relation between the source data and the cache data and each data interface. If the data information is the same as the cache data, the data information corresponding to the page to be loaded is proved to be not updated, and the cache data can be still displayed, namely the cache data is still displayed by the initial display page. And if the data information corresponding to the page to be loaded is not completely the same, proving that the data information corresponding to the page to be loaded is updated, refreshing the initial display page, and displaying the information corresponding to the source data.
In addition, only the data information of partial data interfaces can be compared according to the corresponding relation of the data interfaces. For example, the page to be loaded has real-time information such as time and temperature, and the data interfaces responsible for acquiring the information need to be updated in real time, while the data of other data interfaces have weak real-time performance and do not need to be updated in real time. According to the corresponding relation between the cache data or the source data and the data interfaces, only the cache data and the source data of the data interfaces corresponding to the data information needing to be updated in real time are compared, and the page to be loaded is updated.
Obviously, the method for preloading the page data provided by the embodiment of the application can display the cache data of the page to be loaded on the page to be loaded, and can display the cache data immediately when the page to be loaded is opened, so that the waiting time for the user side to check the data is reduced. And meanwhile, source data corresponding to the page to be loaded can be acquired from a network or other real-time data sources, whether the initial display page needs to be updated or not is determined according to the source data and the cache data, and based on the source data and the cache data, the data information on the finally obtained target display page can be ensured to be the latest data. On the basis, the user side can be guaranteed to be capable of timely checking information and obtaining the latest data information.
The following is a detailed description of the inventive arrangements.
In the above description of the cache database, the cache database stores the data loaded by each page when the page is opened last time, but if the page to be loaded is opened for the first time, or the cache database can clear the cache data at regular time, the cache data corresponding to the page to be loaded does not necessarily exist in the cache database. Based on this, before executing the step S110, the embodiment of the present application further needs to execute a step of pre-storing page data as needed for the page to be loaded, that is, acquire the data of the page to be loaded in advance and store the data into the cache database as cache data, and the specific processing procedure may include:
Responding to a pre-loading request of a page to be loaded received at a front page of the page to be loaded, and acquiring a cache database corresponding to the page to be loaded; inquiring whether cache data corresponding to each data interface of a page to be loaded and a cache address are stored in the cache database, wherein the cache address is a data storage area corresponding to each data interface of the page to be loaded; if each data interface has corresponding cache data, executing the step of obtaining the cache data corresponding to each data interface of the page to be loaded from the cache database; if not each data interface has corresponding cache data, determining the data interface without cache data as a preloaded data interface; acquiring the pre-load data corresponding to the pre-load data interface; storing the preloaded data in a data storage area corresponding to the cache address corresponding to the preloaded data interface of the cache database, and executing the step of obtaining the cache data corresponding to each data interface of the page to be loaded from the cache database.
And acquiring a preloading request of the page to be loaded from a front page of the page to be loaded, providing a page which is possibly used in the future for the front page by adopting a prefetch, determining the page as the page to be loaded, and simultaneously, providing the preloading request of the page to be loaded for the front page. Or receiving the preloading request of the page to be loaded by responding to the mode that the user side clicks the entry of the page to be loaded on the front page. And acquiring a cache database corresponding to the page to be loaded based on the preloading request.
After the cache database is obtained, whether cache data corresponding to the page to be loaded is stored in the cache database or not needs to be determined, so that repeated loading of the data is prevented, and the cache data is repeated. If it is determined that the cache database stores the cache data corresponding to each data interface of the page to be loaded, the cache data can be directly obtained from the cache database, and the processing flow of the page data preloading method can be further executed. If it is determined that the cache data corresponding to the page to be loaded is not stored in the cache database, or the complete cache data corresponding to each data interface of the page to be loaded is not stored, further obtaining missing cache data is needed.
And assuming that the display of the page to be loaded requires data of three data interfaces, determining the data interface of the missing cache data as a pre-load data interface, and simultaneously acquiring a cache address corresponding to the pre-load data interface so as to accurately store the acquired data in a cache database. Based on the data information, the data information corresponding to the preloading data interfaces is acquired from a network or the specific data source of the page to be loaded, and if a plurality of preloading data interfaces exist, the data information corresponding to each preloading data interface is acquired respectively. Further, based on the corresponding relation between the data information and the preloaded data interface, the data information is stored on a cache address corresponding to the preloaded data interface, and the data information is determined to be cache information. Based on this, when the step S110 is executed, it may be ensured that the cache database must store cache data corresponding to each data interface of the page to be loaded.
And performing operations such as layout, rendering and the like on the cache data corresponding to each data interface of the page to be loaded, and displaying the cache data on the page to be loaded to obtain an initial display page for a user to view corresponding data information. While the page to be loaded sends a data request to the network or the data source to acquire the source data corresponding to each data interface of the page to be loaded while acquiring the cache data from the cache database, the process of acquiring the source data generally requires the application of a network signal, so that the acquisition time of the source data is longer than the acquisition time of the cache data even though the process is performed simultaneously.
In addition, a target display page needs to be determined through the source data and the cache data, and whether the initial display page needs to be updated or not is determined through the target display page. In the embodiment of the application, the consistency of the source data and the cache data of each data interface of the page to be loaded needs to be determined, and if the source data and the cache data of each data interface are identical, the initial display page does not need to be refreshed again, and the initial display page is determined to be a target display page. And if the source data and the cache data of each data interface are completely different or not completely the same, the initial display page needs to be refreshed (updated) based on the source data of all the data interfaces, and the refreshed initial display page is determined to be a target display page.
Specifically, by comparing the cache data corresponding to each of the data interfaces of the page to be loaded with the source data, the process of determining the consistency of the source data and the cache data of each of the data interfaces of the page to be loaded may include: converting the cache data and the source data of each data interface into data values of the same type, and obtaining a first contrast value corresponding to the cache data of each data interface and a second contrast value corresponding to the source data of each data interface, wherein the character lengths of the first contrast value and the second contrast value are equal; comparing whether the first comparison value and the second comparison value of each data interface are all the same; if all the cache data and the source data are the same, determining that the cache data and the source data are the same; if not all the data are the same, determining that the cache data and the source data are different.
In the embodiment of the application, the process of determining the data consistency of the multiple data interfaces can be processed through the SVPCachManager, and meanwhile, a hash algorithm (hash) is adopted to convert the source data and the cache data of each data interface of the page to be loaded into the same type of data value, namely, the hash value with the same length of characters, and the hash value is used as the identification of data comparison. For example, the page to be loaded is provided with three data interfaces a, b and c, and the buffer data of the data interfaces a, b and c are converted through SVPCacheManager and three corresponding hash values are collected; processing source data of a single data interface requested from a network end or a data source, and collecting three corresponding hash values to obtain a hash value of one cache data and one source data corresponding to each data interface respectively, for example: the data interface a-cache data h 1-source data h1, the data interface b-cache data h 2-source data h2, the data interface c-cache data h 3-source data h3, and each pair of hash values are respectively obtained by converting cache data and source data corresponding to the same data interface. And returning a comparison result, namely comparing h1-h1, h2-h2 and h3-h3, by an isquat method of the manager, and returning the comparison result, so as to determine which data interface has different source data and cache data, if all the data of the three interfaces are the same, returning true, and if the data of the three interfaces have different data, returning false, and further determining that the initial display page needs to be updated based on all the source data.
When it is determined that the cache data of one or more data interfaces are different from the source data, the source data of all the data interfaces can be utilized to comprehensively refresh the initial display page, and a target display page which is laid out and displayed by all the source data is obtained. If the false is returned, and it is determined that the cache data hash value h3 of the data interface c is different from the source data hash value h3, the initial display page may be refreshed by using the source data corresponding to the data interfaces a, b and c, so as to obtain the target display page.
If the page to be loaded can only update data corresponding to a certain data interface on the initial display page, based on the above example, the cached data corresponding to the data interface c on the initial display page can be updated by using the source data corresponding to the data interface c to obtain the target display page.
In addition, since there are many fields that are easy to change in the cache data and the source data, such as an expere time timestamp related to time, or an html tag string for an H5 page, and some unused fields play count format, these fields all belong to variable fields, and when data conversion is performed on the cache data and the source data, the variable fields may cause a difference between a converted hash value and information expressed by original data, so that a comparison result of a hash value obtained by SVPCacheManager is inaccurate, and a subsequent page refresh is affected.
In addition, when the cache data and the source data are converted into the same type of data value, the cache data and the source data need to be converted into the same data format, so that abnormal conversion caused by different data formats during conversion into the same data value is prevented. In the embodiment of the application, all the cache data and the source data are converted into Dictionary data (Dictionary), and corresponding hash values are further calculated and compared with data consistency. For example, if the obtained cache data and source data are json data, the json data of the cache data and the source data may be converted into Dictionary data by the IOS system if the data are to be compared for consistency. In addition, since the sequence of keys in the Dictionary data obtained by conversion is different, and the conversion process is irregular, dictionary data obtained by converting the same data information in the same data format or in different data formats is different. Based on the above, the hash value obtained by Dictionary data conversion aiming at the same data information is not necessarily the same every time, which can affect the accuracy of data comparison between cache data and source data, so that a page to be loaded can be repeatedly refreshed, and the effect of displaying the page at the user side is affected.
In order to avoid the above problem, in the embodiment of the present application, when converting the cache data and the source data of each data interface into the same type of data value, the following operations are further required to be performed on the cache data and the source data: acquiring volatile fields in the cache data and the source data, wherein the volatile fields comprise characters or fields which are easy to change or have no practical significance in the data transmission process; deleting volatile fields in the cache data and the source data to obtain target cache data and target source data; and respectively sequencing the target cache data and target characters of the target source data to obtain ordered target cache data and ordered target source data, wherein the target characters at least comprise a key array and a value array. Further, the ordered target cache data and the target update data are respectively calculated to obtain a first contrast value corresponding to the ordered target cache data and a second contrast value corresponding to the ordered target source data.
All the variable fields may be listed in advance, and after the cache data and the source data are acquired, the listed variable fields are identified from the cache data and the source data. In actual operation, one KeyPath may be listed in advance for all the variable fields, and written into the execution program, and after the variable fields are determined based on the KeyPath, the operation of deleting the corresponding fields from the Dictionary is directly executed through KVC, so as to obtain corresponding target cache data and target source data.
Further, sorting processing is carried out on the target cache data and the target source data. Taking the target cache data as an example, firstly, a variable String is required to be defined, firstly, starting from a root node of the target cache data, sequencing a key array of the root node, converting a sequencing result (the ordered key array) into a String, and then adding the String. And then, the corresponding value is taken out from the target cache data through the ordered key array, and the non-dictionary and the array value are added to the String one by one. And then recursively calling the method, and inputting the value as the value of the dictionary and the array. If the array object is transmitted, traversing the non-dictionary and the value of the array, adding the non-dictionary and the value of the array to String one by one, and then carrying out recursion calling and transmitting parameters. The above-described actions are recursively repeated until recursion is to a leaf node of the cached data. Based on the result, an ordered Dictionary ordered target cache data can be obtained. Similarly, the method can be used for processing the target source data to obtain the ordered target source data.
And then converting the ordered target cache data and the ordered target source data into unified data type values, comparing, and performing corresponding operation on the initial display page. And if the comparison result is that the cache data is different from the source data, the data corresponding to the page to be loaded is proved to be updated, and the initial display page is refreshed, so that the cache data of the page to be loaded in the cache database needs to be further updated while the display page displays the latest data information. Otherwise, when the page to be loaded is opened next time, the cached data is only more delayed, and even if the page to be loaded can be displayed in time, the data with more utilization value cannot be provided for the user side.
Therefore, if the cache data is different from the source data, deleting the cache data corresponding to each data interface of the page to be loaded in the cache database; and obtaining a cache address corresponding to each data interface, wherein the cache address refers to a data storage area corresponding to each data interface of the page to be loaded. Further, the source data of the corresponding data interface is stored in the cache address, and after the storage is completed, the stored source data is equivalent to the cache data which needs to be acquired when the page to be loaded is opened next time.
In addition, when the scheme is applied, the scheme is considered to directly replace the original page data preloading method, if the page data preloading method of the scheme causes problems in the system operation, even hidden danger of system breakdown can exist, the use of a user is more influenced, and the waiting time of the user is increased. Therefore, in the embodiment of the application, a degradation strategy is further added, the original scheme is not directly covered, but the page data preloading method of the scheme is inserted into the original system, the priority of the scheme is set higher than that of the original scheme, when the page data is loaded, the page data preloading method of the scheme is preferentially used, if the scheme has a problem in system operation, the scheme for loading the page data is integrally switched into the original scheme, the page loading method of the original scheme is executed, and the problems of system breakdown and the like caused by new functional online of the page data preloading can be avoided based on the scheme.

In addition, when a page stays in an a page, there are entries of multiple pages on the a page, and the selected page may be uncertain, and it cannot be determined that the page has no corresponding cache data. The A page receives a signal of a page which can be opened, namely a B1 page or four pages B1-B4, and before a user side executes a mouse arrow clicking operation, whether the page which can be opened has corresponding cache data or not is determined from a cache database, if not, corresponding source data is timely obtained from a network side and is stored in the cache database, so that when the user wants to open the page which can be opened, the cache data can be directly called out from the cache database and displayed, and the time for the user to wait for the page to display the data is reduced.
