Fig. 3 is a flowchart illustrating a code recovery method according to an embodiment of the present application. As shown in fig. 3, the method may include the following steps S210-S230.
Step S210: when the page script file of the client has an error report, the client sends a code repair request to the server; the code repair request comprises an error file link, a code error position and a code error type.
When a user accesses the Web system, the error reporting phenomenon may occur in the page script file in the Web system, so that the Web system stops operating and the user accesses the Web system is affected. The page script file is composed of JavaScript codes, so error codes of the JavaScript are required to be repaired.
When the page script file of the client side has an error report, the client side sends a code repair request to the server side, wherein the code repair request comprises an error file link, a code error position and a code error type; the error file link and the code error position can help the server to accurately position the error code position, and the code error type is convenient for the server to determine the code error type of the error code, so that the server can better repair the error code.
The method for determining the error report phenomenon of the page script file by the client comprises the following steps:
and registering an error triggering event by the client, and determining that the page script file has an error report when the error triggering event is detected.
The error triggering event is an operation event registered by the client, and means that when the error reporting phenomenon occurs in the page script file in the client, the operation event is triggered, so that when the error triggering event is detected, the client can determine that the page script file has an error report.
Step S220: and the server determines a code repair method according to the code repair request and repairs the error code according to the code repair method.
The specific method for the server side to repair the error code is as follows:
and the server side searches a regular expression corresponding to the code error type according to the code error type indicated by the code repairing request, and repairs the error code according to the regular expression.
The method comprises the steps that a server side analyzes a code repairing request after receiving the code repairing request, code error positions and code error types are determined, each code error type corresponds to one code repairing method, the repairing method in the application is that regular expressions are used for repairing error codes, each code error type is provided with a corresponding regular expression, and a specific repairing means is that searching and replacing are carried out through the regular expressions.
For example, the types of common code errors and the repair method in the page script file are as follows:
(1) uncaught URIError: when the error reporting phenomenon occurs in the running process of the page script file, the page script file is proved to have URI errors, and the repairing method at the moment is that the regular expression is positioned to the position of an error code through a code repairing request, and the error code is replaced by a null statement to delete the URI error code, so that the page script file can run normally;
(2) uncaught Syntax Error: when the error reporting phenomenon occurs in the running process of the page script file, the page script file is proved to have reference errors, namely the referenced object attribute exists in the code and the object of the referenced object attribute is null, the repairing method is that the regular expression is positioned to the position of an error code through a code repairing request, and a judging statement is added at the referenced object attribute in the code, so that when the page script file executes the operation of the referenced object attribute, whether the object of the referenced object attribute is null or not is judged firstly, and only when the object exists, the operation of the referenced object attribute is executed;
(3) uncaught type error: when the error reporting phenomenon occurs in the running process of the page script file, the page script file is proved to have an overflow error, namely the actual size of a variable is larger than the size of a storage space allocated to the page script file by a client, so that the variable overflow phenomenon occurs;
(4) uncaught Range error: when the error reporting phenomenon occurs in the running process of the page script file, the page script file is proved to have assignment errors, for example, a variable A and a variable B exist in the page script file, the assignment of the variable B depends on the variable A, but the variable A is not assigned in the script file, so the error reporting phenomenon occurs; the restoration method comprises the steps that a regular expression is positioned at the position of an error code through a code restoration request, and a judgment statement is added at a variable B in the code, so that when a page script file executes an assignment statement, whether the variable A is subjected to assignment operation or not is judged, and only when the variable A is subjected to assignment operation, the assignment operation on the variable B is executed, so that the assignment error is eliminated;
(5) uncaught ReferenceError: when the error reporting phenomenon occurs in the running process of the page script file, the page script file is proved to have URI errors, and the repairing method at the moment is that the regular expression is positioned to the position of an error code through a code repairing request, and the error code is replaced by a null statement to delete the URI error code, so that the page script file can run normally;
(6) uncaught EvalError: when the error reporting phenomenon occurs in the running process of the page script file, the page script file is proved to have an Eval grammar error, the repairing method at the moment is that the regular expression is positioned to the position of an error code through a code repairing request, and an Eval statement is replaced by a null statement to delete the Eval error code so as to eliminate the Eval grammar error.
Therefore, the regular expression can be used for repairing error codes in the page script file, so that the page script file can normally operate, and a user can normally access the Web system.
Step S230: and the client receives a repair completion notification returned by the server according to the code repair request, and the client reloads the page script file from the server in response to the repair completion notification.
And after the server side finishes repairing, a repairing completion notice is returned to the client side so as to trigger the client side to reload the page script file, so that the webpage can run normally.
An embodiment of the present application provides a code recovery method, which recovers an error code in a script file of a Web page through a regular expression, so that a user can normally access a Web system, and the Web page can normally operate.
