[0027] This application will now be described with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1 As shown, this application provides a method for recording table data modification logs based on Uliweb, the method including:

[0030] Step S100: Obtain the user request;

[0031] Step S200: When the user request arrives at the server, the thread processing middleware preprocesses the user request and records the user information in the user request into local variables;

[0032] Step S300: The server processes the user request and obtains data change information;

[0033] Specifically, in a business system, when data in the database changes due to user interface operations, API calls, or other reasons, these modifications are crucial audit evidence and troubleshooting information in case of anomalies, and therefore need to be logged. There are generally two ways to log data modifications: The first method involves writing code at all possible points of data change to read the data before the change and store it in a temporary variable. Then, the code compares the fields of the data before and after the change, identifies the differences, manually records these differences to a file or other medium, and finally saves the changed data to the database. The second method, without intruding into the business code, involves analyzing the database's binary log to parse out the data changes.

[0034] The user request is a request message sent by a user, including a modification request, an addition request, a deletion request, a calling request, etc. When the user request reaches the server, the threading middleware pre-processes the user request, that is, when the user interface operation or api interface calling request reaches the backend service, the threading middleware pre-processes the request, saves the user information in the user request in a local variable, and the local variable is a variable defined in the function. Some user requests will modify the backend data, causing data changes. The Uliweb framework processes the data before and after the change, and the data change information is the data before and after the modification. The data before and after the modification is recorded in a variable.

[0035] Step S400: according to the type of the data change information, different request instructions are sent, and the data change information is taken as an instruction parameter;

[0036] Further, according to the type of the data change information, different request instructions are sent, and the data change information is taken as an instruction parameter. Specifically, it is judged whether the type of the data change information is deletion data. If it is deletion data, a post_delete instruction is sent, and the data to be deleted is taken as an instruction parameter. If the type is not deletion data, it is addition or modification data, a post_save instruction is sent, and the data before and after the modification is taken as an instruction parameter. Different request instructions are sent for different data change types, and the subsequent technical effect of automatically recording logs for all data changes in the project is achieved.

[0037] Step S410: judging whether the type of the data change information is deletion data;

[0038] Step S420: if the type is deletion data, a post_delete instruction is sent.

[0039] Further, the present application S410 further includes:

[0040] Step S411: if the type is not deletion data, a post_save instruction is sent.

[0041] Specifically, according to the type of the data change information, different request instructions are sent, and the data change information is taken as an instruction parameter. Specifically, it is judged whether the type of the data change information is deletion data. If it is deletion data, a post_delete instruction is sent, and the data to be deleted is taken as an instruction parameter. If the type is not deletion data, it is addition or modification data, a post_save instruction is sent, and the data before and after the modification is taken as an instruction parameter. Different request instructions are sent for different data change types, and the subsequent technical effect of automatically recording logs for all data changes in the project is achieved.

[0042] Step S500: the code application program receives the request instruction through the instruction distributor, parses the instruction parameter, and obtains the data change information;

[0043] Further, the present application S500 further includes:

[0044] Step S510: the code application includes the thread processing middleware and view, wherein the thread processing middleware pre-processes the user request, and the view is used to process the code logic of the log.

[0045] Further, the present application S510 further includes:

[0046] Step S511: when the Uliweb service starts, the code application is loaded.

[0047] Step S512: the process_post_save method in the view of the code application is bound with the post_save instruction, the process_post_delete method is bound with the post_delete instruction, and the Middleware middleware of the thread processing middleware is registered in the instruction distributor.

[0048] Specifically, the code application is model_change_log app, and the model_change_log is the app name of the code specifically implemented in the Uliweb project. The app is a code unit in the Uliweb framework. Uliweb is an open source web development framework written in Python language, and Uliweb is composed of multiple apps. Each app can have its own configuration file, template directory, and static directory. Existing applications can be easily reused and considered as a whole.

[0049] The code application program model_change_log app includes the threading_middleware and views, wherein the threading_middleware preprocesses the user request, records the user information in the request to a local variable which can be accessed across threads. The views are code logic for processing the log. When the Uliweb service starts, all apps are initialized, at this time, the process_post_save method in the views of the model_change_log app is bound with the post_save instruction, the process_post_delete method is bound with the post_delete instruction, and is registered to the instruction distributor. At the same time, the ThreadingMiddleware in the threading_middleware is registered to the middleware list of the project, wherein the Middleware is a kind of middleware in the Uliweb framework, which is used for preprocessing and post-processing of the request. The technical effects are achieved by embedding the project code in the form of an independent app, without modifying other codes in the project, with low code invasion, and without parsing Binlog, reducing the difficulty of implementation.

[0050] Step S600: reading the user information in the local variable, and recording the user information and the data change information to a log file.

[0051] Further, the reading the user information in the local variable, and recording the user information and the data change information to a log file, the present application S600 further includes:

[0052] Step S610: calling a save_log function;

[0053] Step S620: reading the user information from the local variable when the save_log function is executed;

[0054] Step S630: recording the user information and the data change information to a log file through the save_log function.

[0055] Specifically, when recording the log file, the save_log function is called to save the log. When the save_log function is executed, the user information is read from the local variable, and the user information is recorded in the log file together with the data change content. This achieves the technical effect of low implementation difficulty without the need to parse Binlog, obtaining the operator information of the page operation, recording the data operator in the log as the basis for auditing, and further achieving the technical effect of automatically recording the log of all data changes in the project.

[0056] In summary, the Uliweb-based table data modification log recording method and system provided by the present application has the following technical effects:

[0057] Due to the adoption of the technical scheme that when a user request reaches a server, a thread processing middleware pre-processes the user request, records user information in the user request to a local variable, the server processes the user request to obtain data change information, sends different request instructions according to the type of the data change information, and takes the data change information as an instruction parameter, a code application program receives the request instruction through an instruction distributor, parses the instruction parameter to obtain the data change information, reads the user information in the local variable, and records the user information and the data change information in a log file. Further, the technical effect of automatically recording the log of all data changes in the project is achieved by embedding an independent app in the project code, with low code invasion, without the need to modify the original project code, without the need to parse Binlog, low implementation difficulty, and the ability to obtain operator information of page operation as the basis for auditing.
