In the following, a detailed description is given of a log file processing method disclosed in an embodiment of the present disclosure, an execution subject of the log file processing method provided in the embodiment of the present disclosure is generally a computing device with certain computing capability, and the computing device includes, for example: a terminal device, which may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle mounted device, a wearable device, or a server or other processing device. In some possible implementations, the log file processing method may be implemented by a processor calling computer readable instructions stored in a memory.
The log file processing method provided by the embodiment of the present disclosure is described below by taking an execution subject as a computer device as an example.
As shown in fig. 2, a flowchart of a log file processing method provided in an embodiment of the present disclosure may include the following steps:
s201: and acquiring a log statement in the log file, wherein the log statement comprises a fixed data part and a variable data part.
In this step, in order to ensure the security of the log file generated during the program running process and avoid the log file collected by the client side from being too large, the log file processing server 12 compresses and encrypts the generated log file.
In specific implementation, in the running process of the program, the engineering file including the log file and other data files may be generated, so the log file processing server needs to first obtain the log file stored in the engineering file. As shown in fig. 3, which is a schematic diagram of a project file provided in an embodiment of the present disclosure, a white frame part indicates a LOG file included therein, and the rest is other included data files, in a specific implementation, a format of the LOG file included in the project file is fixed, and as can be seen in fig. 3, a LOG statement starts with "LOG"; the method comprises the steps that a format of ending appears, preset format storage information can be set based on the format, a log file processing server carries out regular matching on an engineering file by using a regular expression which is the same as the preset format storage information, a stored log file can be obtained, further, log statements in the log file can be determined by using the log file, then the log statements are analyzed by using the regular expression again, a fixed data part and a variable data part in the log statements can be determined, and in addition, when the log statements stored in the log file are obtained, identifiers corresponding to the log statements can be generated in a self-adding mode according to the sequence of the obtained log statements.
Taking the code segment included in the engineering file shown in fig. 3 as an example, the LOG file processing server matches the LOG file in the engineering file according to the preset format storage information ("LOG;") to obtain a LOG file LOG (LS _ INFO, APP _ variation _ MODULE) < "Request video stream ssrc: "< < ssrc <" width: "< < width < <" height: "< < height; (ii) a Further, it can be determined that the log statement in the log file is "Request video stream ssrc: "< < ssrc <" width: "< < width < <" height: "< < height; "; then, analyzing the data by using a regular expression to determine the invariable data' Request video stream ssrc: "< < < <" > width: "< < < <" height: "<; "as a fixed data part, the changed data" ssrc, width, height "is determined as a variable data part, and in addition, assuming that the log statement acquired in this step is the first log statement of the log file, it can be determined that the identifier of this log statement is 1.
S202: the log statement in the log file is replaced with the variable data portion and an identifier of the log statement.
In a specific implementation, the generated log statement identifier and the determined variable data part may be combined into a target log statement, in an implementation, the log statement identifier may be placed in front of the variable data part, and taking the log statement in fig. 3 as an example, the target log statement after combination may be determined to be 1, ssrc, width, height; in another embodiment, the log statement identifier may be placed behind the variable data portion, and the combination manner of the log statement identifier and the variable data portion in the embodiment of the present disclosure is not limited in the embodiment of the present disclosure, and further, the combined target log statement may be used to replace the log statement in the acquired log file.
For example, for the log statement "" Request video stream ssrc: "< < ssrc <" width: "< < width < <" height: "< < height; "replace, can get the goal journal statement after replacing 1, ssrc, width, height.
S203: and storing the identifiers of the fixed data part and the log statement in a log statement mapping table, wherein the log statement mapping table is used for restoring the identifiers of the variable data part and the log statement in the replaced log file into the log statement.
In this step, in order to restore the replaced log file, a log statement mapping table for storing the fixed data portion and the identifier of the log statement needs to be generated.
In specific implementation, a position of variable data in a log statement is determined based on a data name corresponding to the determined variable data portion, and then the variable data portion at the corresponding position in the log statement is replaced with a uniform data identifier, for example, the uniform data identifier may be a placeholder, and further, the replaced log statement is taken as a fixed data portion, and an identifier generated in the process of obtaining the log statement is stored in a log statement mapping table as a whole, taking the log statement included in fig. 3 as an example, a log statement after being replaced with the placeholder is "Request video stream ssrc: "< <% d <" width: "<% d <" height: "< <% d; (ii) a Wherein, "% d" represents a placeholder, the data content in the log statement mapping table may be 1, and "Request video stream ssrc: "< <% d <" width: "<% d <" height: "< <% d; . Further, after the obtained log statement is replaced by the target log statement, the log file processing server normally compiles the engineering file of which the log file has been replaced, and generates a preprocessing program only containing the target log statement. Based on this, even if the preprocessing program is leaked, the analyzed log statement only comprises the identifier and the variable data part, no associated context information exists, and if the generated log statement mapping table is not used as a reference, the obtained identifier and the variable data part have no practical significance, so that the leakage of user information is not caused, and the security of the log file is ensured.
Furthermore, when the user needs to acquire the stored log file, an operation instruction for the replaced log file is submitted to the client, the client sends an operation instruction for the replaced log file to the log file processing server according to the operation instruction, and the log file processing server restores the replaced log statement in response to the received operation instruction for the replaced log file.
As shown in fig. 4, a flowchart for restoring a replaced log statement provided in an embodiment of the present disclosure may include the following steps:
s401: in response to an execution instruction to the replaced log file, an identifier of the log statement is obtained from the replaced log file.
In specific implementation, the log file processing server responds to an operation instruction of the replaced log file, analyzes the generated preprocessing program, can acquire each target log statement in the replaced log file, and matches each acquired target log statement by using a regular expression, and can acquire an identifier of the target log statement, where it is to be noted that the identifier of the target log statement is the identifier of the log statement acquired in the replaced log file. In addition, an identifier representing an unreplaced log statement that coincides with the identifier of each acquired target log statement exists in the generated log statement mapping table.
S402: based on the identifier of the log statement, the fixed data portion of the log statement is obtained from the log statement mapping table.
In a specific implementation, according to the identifier of the obtained log statement, an identifier corresponding to the identifier of the obtained log statement is matched from the generated log statement mapping table, and based on the identifier, the fixed data part of the un-replaced log statement stored in the log statement mapping table can be obtained.
S403: the variable data portion in the replaced log file and the identifier of the log statement are restored to the log statement based on the fixed data portion of the log statement and the variable data portion of the log file stored in the replaced log file.
In specific implementation, according to the fixed data part of the log statement stored in the log statement mapping table determined in S402, a uniform data identifier position included in the fixed data part may be determined, in addition, according to the identifier of the target log statement included in each extracted target log statement, a variable data part corresponding to the target log statement may be determined, according to the determined uniform data identifier position, each uniform data identifier is replaced by the variable data part, a log statement that is not replaced may be obtained, further, a log file that is not replaced may be obtained, and then the target log statement in the replaced log file is replaced by the log statement of the log file that is not replaced, based on which, the log recovery statement may be implemented.
