[0046] Figure 1 The system 100 may be configured and operated in various ways to enable the application of various methods and apparatuses described in the present disclosure.

[0047] Usually, when upgrading a mini program, it is necessary to re-download the full package. Most of these files already exist on the client, which is equivalent to repeated downloads, wasting a huge amount of bandwidth resources. Bandwidth is one of the largest costs for Internet companies, which results in huge cost losses. At the same time, the full package data needs to be downloaded, which consumes a lot of unnecessary user traffic and brings a bad user experience to users. Because the upgrade of mini programs is implicit, in most cases the upgrade is performed the moment the mini program is opened, and the upgrade of the full package requires a longer download time, which affects the opening speed of the mini program and seriously affects the user experience.

[0048] Therefore, according to an embodiment of the present disclosure, a method 200 for updating an application program running on a server is provided, such as Figure 2 As shown, the method 200 includes: in response to receiving an application package of a new version of an application, comparing the application package of the new version with the application package of a historical version of the application (step 210); generating a description file based on the comparison result, wherein the description file records information about files that have changed in the new version of the application package relative to the application package of the historical version (step 220); and generating an upgrade package for the application based on the description file and the changed files in the new version of the application package (step 230).

[0049] According to the embodiments of the present disclosure, only the changed parts of the application can be updated based on the upgrade package, which saves enterprise bandwidth and user traffic, improves the efficiency of application update, and optimizes user experience.

[0050] In step 210 , in response to receiving the application package of the new version of the application, the application package of the new version is compared with the application package of the historical version of the application.

[0051] According to some embodiments, Figure 3 As shown, step 210 may include: in response to receiving a new version of an application package, obtaining one or more latest historical version application packages of the application (step 310); and comparing the obtained historical version application packages with the new version application package respectively to determine the files in the new version application package that have changed relative to each historical version application package (step 320).

[0052] According to some embodiments, Figure 4 As shown, obtaining one or more latest historical versions of an application package of an application (step 310) includes: obtaining an identifier of the application corresponding to the new version of the application package (step 410); determining information of the application package of the historical version of the application based on the identifier (step 420); and obtaining one or more latest historical versions of the application package based on the determined application package information (step 430).

[0053] In some examples, the identifier of the application can uniquely specify the corresponding application, for example, the identifier of the application can be an application ID. According to some embodiments, the application in the present disclosure can also be a small program, so the small program package that needs to be compared can be obtained through appkey (the unique identifier of the small program).

[0054] According to some embodiments, determining the application package information of the historical version of the application according to the identifier (step 420) includes: determining the application package information of the historical version of the application based on an application package information table. The application package information table may include the identifier of the application, the version number and storage address of each version of the application.

[0055] In some examples, information of various versions of an application may be summarized in an application package information table, so that information of all versions of the application may be obtained at one time by querying the application package information table. This is convenient and fast, greatly improving the efficiency of data transmission and comparison, and saving application update time.

[0056] In some examples, it is possible to set up a predetermined number of latest historical versions of application packages to be obtained. For example, when a developer submits a new version of an application package to the developer platform, the platform automatically obtains the corresponding historical version of the application package (for example, through the application ID), and obtains the 5 latest historical versions of the application package by default. By obtaining multiple latest historical versions of the application package, even if the client application has not been updated for many times (i.e., it is different from the latest version by multiple versions), the application can still be updated through the method according to the present disclosure.

[0057] According to some embodiments, Figure 5 As shown, comparing the obtained historical version of the application package with the new version of the application package respectively (step 320) includes: calculating each file in the historical version of the application package and the new version of the application package respectively through a verification algorithm (step 510); comparing the calculated files in the historical version of the application package with the calculated files in the new version of the application package (step 520); and determining the files in the new version of the application package that have changed relative to the historical version of the application package based on the comparison results (step 530).

[0058] For example, the version numbers corresponding to the historical versions of the application packages obtained are 2, 3, and 4, respectively, and the version number of the new version of the application package uploaded by the developer is 5. The files in each version of the application package are calculated by the verification algorithm and then compared. That is, the application package with version number 2 is compared with each file in the new version of the application package with version number 5, the application package with version number 3 is compared with each file in the new version of the application package with version number 5, and the application package with version number 4 is compared with each file in the new version of the application package with version number 5, so as to confirm that the new version of the application package corresponds to each historical version of the application package through comparison. There are changed file information.

[0059] Files with the same name and location in different versions of application packages are calculated using a verification algorithm. If the contents of the two files are exactly the same, the calculated values ​​should also be the same; if the contents of the two files are changed, the calculated values ​​should also be different. This allows the information of the changed files to be quickly and accurately determined.

[0060] According to some embodiments, the changed files include one or more of the following groups: updated files, newly added files, and deleted files. Figure 6As shown, determining the files that have changed in the new version of the application package relative to the historical version of the application package based on the comparison result (step 530) includes: in response to the different calculation results of the files with the same name and location in the historical version of the application package and the new version of the application package, determining that the files in the new version of the application package are updated files relative to the historical version of the application package (step 610); in response to the files only existing in the new version of the application package, determining that the files in the new version of the application package are newly added files relative to the historical version of the application package (step 620); and in response to the files only existing in the historical version of the application package, determining that the files in the historical version of the application package are deleted files relative to the new version of the application package (step 630). Steps 610 to 630 are not used to indicate the order of their execution, but are only used to indicate various situations that may occur during the comparison process.

[0061] That is, for the historical version of the application package and the new version of the application package, the files with the same position and the same name in the two application packages are verified through a verification algorithm and then their values ​​are compared. If the calculated values ​​are the same, they are recorded as the same files; if they are different, they are recorded as updated files; if a file only exists in the new version of the application package, the file is recorded as a newly added file; if a file only exists in the historical version of the application package, the file is recorded as a deleted file.

[0062] By comparing the files in the new version of the application package with the files in the previous version of the application package, it is possible to determine which files have been updated, deleted, or added to the new version of the application package, so that a complete update or upgrade from the previous version to the new version can be achieved based on the comparison results. Based on this, it can not only save the bandwidth and traffic consumed when updating the application, but also improve the update efficiency of the application and the user experience.

[0063] According to some embodiments, the verification algorithm includes any one of the following group: md5 algorithm, sha1 algorithm, sha256 algorithm, mssql algorithm. Of course, it should be understood that other suitable verification algorithms are also possible and are not limited here.

[0064] For example, the md5 algorithm can be used to calculate each file in the historical version of the application package and the new version of the application package. The md5 value obtained after calculation is a unique value calculated by the file attribute and the algorithm. This value will change after the file or folder is changed, so it can be used as a means of verifying whether a file has been modified.

[0065] In step 220, a description file is generated according to the comparison result, and the description file records information about files that have been changed in the new version of the application package relative to the historical version of the application package.

[0066] In some examples, the list of files in one of the historical versions of the application package obtained is as follows:

[0067]

[0068] The file list in the new version of the application package is as follows, where " / / update" indicates that the file content is updated compared to the historical version.

[0069]

[0070]

[0071] According to the comparison process described above, app.json, pkginfo.json, and page / home / index.html are recorded as updated files, page / home / indexa.js is recorded as a newly added file, and images / api.png is recorded as a deleted file. Thus, a description file can be generated. The description file obtained based on the above example is as follows:

[0072]

[0073] In this way, the client application can be updated and upgraded according to the description file later.

[0074] In step 230, an upgrade package of the application is generated based on the description file and the changed files in the new version of the application package.

[0075] According to some embodiments, Figure 7 As shown, step 230 may include: packaging the description file and the changed files in the new version of the application package to obtain an upgrade package (step 710); and storing the information of the upgrade package in the upgrade package information table to update the application of the client based on the upgrade package information table (step 720). For example, the upgrade package information table may include the respective version numbers of the new version of the application package and the historical version of the application package corresponding to the upgrade package, the identifier of the application, and the storage address of the upgrade package.

[0076] The description file and the new and updated files in the new version of the application package are packaged together. In this way, when the client application needs to be updated later, the description file and the changed files in the new version of the application package can be obtained at the same time, so that the client application can be updated based on the description file and the changed files, saving traffic and update time, and improving update efficiency and user experience.

[0077] In some examples, the description file obtained and the files that need to be updated and added to the client application can be packaged into a compressed file as an upgrade package. The naming format of the compressed file can be: the version number of the corresponding historical version-the version number of the new version. Subsequently, based on the corresponding version number, the upgrade package corresponding to the current version of the client (not updated, as the historical version) and the new version newly developed by the developer can be obtained to update the client application based on the upgrade package.

[0078] According to some embodiments, the method 200 of the present disclosure may further include: performing real machine detection on the generated upgrade package to update the client application based on the real machine detection result. Through real machine detection, the risk of failure in the update operation can be reduced, greatly optimizing the user experience.

[0079] In some examples, the upgrade package that passes the real machine detection is stored and the information of the upgrade package is stored in the upgrade package information table for subsequent update and upgrade of the client application.

[0080] According to some embodiments, the method 200 according to the present disclosure may further include: receiving an update request for the application from a client. The update request may include a version number of the current version of the application of the client. In some examples, such as Figure 8 As shown, updating the client's application based on the upgrade package information table (step 720) may include: determining the new version of the application package corresponding to the application based on the version number of the current version of the application of the client (step 810); in response to the existence of the new version of the application package, determining the upgrade package corresponding to the new version of the application package and the current version of the application based on the upgrade package information table (step 820); and in response to the existence of the upgrade package corresponding to the new version of the application package and the current version of the application, obtaining the upgrade package so that the client's application is updated based on the upgrade package (step 830).

[0081] Based on the version number of the client and the version number of the latest version of the application package, the corresponding upgrade package can be accurately located, thereby achieving rapid update and upgrade of the client application.

[0082] According to some embodiments, the application is updated based on a content distribution network.

[0083] In some examples, the application packages of various versions uploaded by the developer and the upgrade packages produced can be stored in the content delivery network (CDN) server. A content delivery network refers to a computer network system interconnected by the Internet, which provides a high-performance, scalable, and low-cost network to deliver content to clients. The content distribution network widely uses various servers, distributes these servers to areas or networks where client access is relatively concentrated, and uses global load balancing technology to direct the client's access to the server that is closest to the client and works normally, and the server directly responds to the client's request. If the content distribution network server does not have the content that the client wants to access or obtain, it will automatically go to the original server to grab the corresponding content and provide it to the client according to the configuration. Therefore, the content distribution network will greatly improve the response speed of client requests, save time for upgrading applications, and further improve the client's user experience.

[0084] According to an embodiment of the present disclosure, a method 900 for updating an application program executed on a client is also provided. Fig. 9 As shown, it includes: sending an update request for the application to the server, wherein the update request includes the version number of the current version of the application of the client (step 910); in response to determining that there is a new version of the application package corresponding to the application and an upgrade package for the current version of the application, obtaining the upgrade package, wherein the upgrade package includes a description file and files that exist in the new version of the application package and have changed relative to the current version of the application, and the description file records information about the files that exist in the new version of the application package and have changed relative to the current version of the application (step 920); and updating the application based on the description file and the files that exist in the new version of the application package and have changed relative to the current version of the application (step 930).

[0085] According to some embodiments, the files with changes include one or more of the following groups: updated files, newly added files, and deleted files. If the files with the same name and location in the historical version of the application package and the new version of the application package are different, then the file in the new version of the application package is an updated file relative to the historical version of the application package; if the file only exists in the new version of the application package, then the file in the new version of the application package is a newly added file relative to the historical version of the application package; and if the file only exists in the historical version of the application package, then the file in the historical version of the application package is a deleted file relative to the new version of the application package.

[0086] In the example of a client user updating a mini-program, when the user opens the client mini-program, he or she will request the server to view the update status of the mini-program. The request parameters include the version number (application package ID) of the current version of the mini-program and the identifier appkey of the mini-program. Upon receiving the request, the server will check whether there is a new mini-program package updated by the developer. If so, it will return is_update=1 and the version number of the new version. At the same time, it will check whether there is an upgrade package from the current version to the latest version, and decide whether to pass the real machine detection based on the real machine detection result. If so and the detection is safe, it will return is_patch=1. The client receives the returned result and performs corresponding operations based on the result. If no update is required (is_update=0), the existing mini-program is opened directly; if an update is required and an upgrade package is available (is_patch=1), the corresponding upgrade package is obtained (for example, through a CDN server).

[0087] After obtaining the upgrade package and decompressing it, read the description file and perform the update operation according to the description in the description file. Based on the example described above, the update process is as follows: replace the app.json, pkginfo.json, and page / home / index.html files (existing in the new version) in the upgrade package with the current version of the mini program package; add the page / home / indexa.js file (existing in the new version) in the upgrade package to the current version of the mini program package; delete the images / api.png file in the current version of the mini program package. After the execution is completed, you can open the mini program to execute the latest version.
