Based on the embodiments of the present invention, any other embodiments obtained by those skilled in the art without creative labor shall fall within the protection scope of the present invention.

Example 1
FIG. 1 is a flowchart of a method for repairing an application program according to the first embodiment of the present invention. This embodiment can be applied to a case where an installed application program is dynamically repaired. Is possible. Specifically, the server side controls the user application program executed on the client side and dynamically corrects it. This method is executed by an application program repair device, which can be implemented by software and is installed on the client side to which the user belongs. As shown in FIG. 1, the method includes the following steps.

  S110: The script plug-in setting information distributed by the server side is received.

  Script plug-ins are used to repair problems with client-side application programs. Normally, when a developer finds a problem with an application program, a script plug-in is developed to repair the problem. Alternatively, update the current script plugin. When the server needs to repair the problem, first, the script plug-in setting information is distributed to the client side. The setting information may be voluntarily distributed to the client side to notify that there is an update of the script plug-in, or the setting information may be transmitted in response to the update request sent out by the client side. The setting information includes basic information of the script plug-in. For example, the setting information may include at least the version number of the script plug-in, and may further include a download address, authentication information, and the like. Since one or more script plug-ins may be updated each time, the setting information distributed at a time may include one or a plurality of version numbers. The server side may distribute the version number of the corresponding script plug-in to the client side based on the client side version.

  S120: A corresponding valid script plug-in is acquired based on the setting information.

  Upon receiving the setting information, the client side can know which script plug-in is to be updated, and obtains a corresponding valid script plug-in based on the information. Specifically, the corresponding script plug-in may be downloaded from the client side, or it may be searched whether or not the script plug-in exists locally. That is, the operation of S120 specifically detects the step of obtaining the version number of the script plug-in from the setting information, and detects that the script plug-in corresponding to the version number is stored locally. If it is not detected that the script plug-in corresponding to the version number is stored locally and the step of making it a valid script plug-in, the corresponding valid script plug-in is downloaded from the server side. Steps.

  The client side can store multiple script plug-ins, and based on the server-side configuration information, identify which script plug-in is currently valid, and launch a valid script plug-in. To repair. In this way, it is possible to prevent the client side from downloading the script plug-in again, and the server side can repair the problem using the existing script plug-in on the client side as needed. Be flexible. The server side can be set to enable the existing script plug-in and the newly distributed script plug-in at the client side at the same time, which can reduce the size of the new script plug-in. It is also possible to reduce the amount of data to be transmitted.

  S130: In the process in which the application program is executed, the effective script plug-in is activated to repair the application program.

  A script plug-in is a patch file that can dynamically repair a problem in an application program, can be executed in a programming environment supported by the application program, and changes the original code of the application program In addition, problems occurring during execution of the application program can be repaired dynamically.

In S130, it is preferable to repair the application program by the following steps. That is,
In the process of executing the application program, activating the valid script plug-in to monitor the function push operation of the application program;
When the push request of the objective function set in the valid script plug-in is found by monitoring, the replacement function in the valid script plug-in executes a push operation instead of the objective function, and executes the replacement function. And repairing the application program.

  Confirmation that there is an objective function to be replaced in the script plug-in can confirm the function name of the objective function, and the script plug-in provides a replacement function to be executed instead of the objective function. . The objective function is usually a function having a problem, and the problem existing in the application program can be repaired by executing the replacement function instead of the objective function. Or you may increase the function of an application program using this method.

  The application program restoration method is particularly applied to an application program of a closed code program developed based on an iOS system. If there is a problem with the application program, the developer can repair the problem in the form of a script plug-in without changing the original application program, so there is no need to go through an examination by the iOS system application door. The programming language used for the script plug-in can be a language that allows an application program to support its execution environment and execute instead of its functions. Preferably, the programming language of the script plug-in is Lua. Language. The Lua language is a lightweight language that is small in size, fast in start-up, easily embedded in other application programs and executed, and has excellent extensibility and functions provided by the host language. Can be used for convenience as if it were a built-in function. After the Lua language script plug-in is downloaded to the client side, when the client-side application program is executed, the client side automatically activates the Lua engine to enable the execution environment, and the script plug-in By enabling the code, the goal of repairing client application program problems is achieved.

  By the invention according to the embodiment of the present invention, for the problem in the client side application program, the server side distributes the script plug-in setting information for repairing the problem to the client side, and the client side based on the setting information, Since the corresponding script plug-in can be automatically acquired, started, and executed, the problem can be repaired without affecting the user's use.

  The client side may further report an execution log, for example, by reporting the execution log to the server side after successful download of the script plug-in or after successful execution of the script plug-in, Developers can know the entire process of requesting, downloading and executing script plug-ins, making it easy to statistics, problem identification and script plug-in code optimization.

  It is preferable because the reliability of problem repair is improved by authenticating the validity of the script plug-in based on the setting information based on the solution described above. The validity authentication may be performed in various ways, and is preferably realized by the version number of the script plug-in and the authentication information.

Example 2
FIG. 2 is a flowchart of the application program restoration method according to the second embodiment of the present invention. In this embodiment, based on the above-described embodiment, the operation for acquiring the corresponding effective script plug-in based on the setting information is specifically optimized. The method of this example is
Step 210 (S210) for receiving script plug-in setting information distributed by the server side;
Acquiring a first version number of the script plug-in from the setting information 220 (S220);
Obtaining a second version number of a valid script plug-in currently used by the local 230 (S230);
Comparing the first version number with the two version numbers and authenticating the validity of the first version number 240 (S240);
If the first version number is valid, obtaining a corresponding valid script plug-in 250 (S250);
In a process in which the application program is executed, a step 260 (S260) of starting the valid script plug-in and repairing the application program is included.

  In the above solution, the first version number is a version number of the script plug-in that is set by the server side and needs to be enabled and used, and the local second version number on the client side is the client side. This is the version number of the script plug-in that is already enabled and used. By comparing the two version numbers, the validity of the script plug-in currently set can be authenticated. For example, if the rank of the first version number is higher than the rank of the second version number, it is determined that the first version number is valid. Otherwise, the client side has actually been updated to a relatively new version and there is no need to update the script plug-in again.

Example 3
FIG. 3 is a flowchart relating to the application program repair method according to the third embodiment of the present invention. Optimize more specifically. The method of this example is
Step 310 (S310) for receiving script plug-in setting information distributed by the server side;
Downloading a corresponding valid script plug-in based on the setting information 320 (S320);
A step 330 (S330) of obtaining a first digest algorithm value of the script plug-in from the setting information;
Calculating a second digest algorithm value of the downloaded script plug-in (S340);
The first digest algorithm value and the second digest algorithm value are compared to authenticate the validity of the downloaded script plug-in. If it is valid, S360 is executed. If it is invalid, S320 is repeated. Step 350 (S350) that executes or terminates the current operation and notifies that there is an abnormality,
In a process in which the application program is executed, a step 360 (S360) of starting the valid script plug-in and repairing the application program is included.

  In the above solution, a digest algorithm of MD5 can be used. The first digest algorithm value is a digest algorithm value calculated and acquired by the server side for the entire script plug-in, and is used as authentication information. The second digest algorithm value is a digest algorithm value calculated and acquired for the script plug-in after the client side downloaded the script plug-in. If the download of the script plug-in is complete and accurate, The digest algorithm values are the same, and the downloaded script plug-in is valid. By authenticating the script plug-in based on the digest algorithm, it is possible to ensure the integrity of the download.

S405, the client side verifies the version information of the script plug-in, determines whether or not the distributed version number is higher than the currently valid version number, and is valid if the currently valid version number is higher, S406 Otherwise, step 405 ending this process;
S406, if the setting information is valid, step 406 for resetting the valid setting information on the client side;
Specifically, the client side replaces the version number of the script plug-in that is currently valid. The client side may delete other script plug-ins that already exist and may store them for later use.
The client side may directly execute the verification and download operation after receiving the setting information. After receiving the setting information and verifying that it is valid, the client side notifies the user, A download operation may be executed accordingly.
S407, the client side downloads the newly set script plug-in, and if the download is successful, executes S408; otherwise, the process ends 407;
S408, after the download is successful, the client side reports the log to the server side, step 408;
S409, the client side verifies the MD5 value of the downloaded script plug-in, that is, compares whether the MD5 value in the setting information matches the MD5 value obtained by downloading and calculating the script plug-in. If the MD5 value of the setting information matches the MD5 value obtained by downloading and calculating the script plug-in, this is a valid script plug-in, and S410 is executed. Otherwise, the process is terminated. 409,
S410, if the script plug-in is valid, start the Lua engine, enable the execution environment of the Lua script plug-in, execute S411 if the start is successful, otherwise terminate the process Step 410 When,
S411, after successfully starting the Lua engine, the client side reports the log to the server side in step 411;
S412, the client side triggers and enables execution of the Lua script plug-in when executing the problematic part, and repairs the problem 412.

  In the solution according to the present embodiment, a Lua + Wax frame may be used, and the client side and the server side cooperate to dynamically and quickly repair problems existing on the iOS client side. Avoiding the submission of new versions or the normal use of the user, the product brings the following benefits:
