In the following, a log file processing method disclosed in the embodiments of the present disclosure is described in detail, where an execution body of the log file processing method provided in the embodiments of the present disclosure is generally a computing device with a certain computing capability, and the computing device includes, for example: the terminal device, or server or other processing device, may be a User Equipment (UE), mobile device, user terminal, cellular phone, cordless phone, personal digital assistant (Personal Digital Assistant, PDA), handheld device, computing device, vehicle mounted device, wearable device, etc. In some possible implementations, the log file processing method may be implemented by way of a processor invoking 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 body as a computer device as an example.
As shown in fig. 2, a flowchart of a log file processing method according to an embodiment of the disclosure may include the following steps:
s201: the method comprises the steps of obtaining a log statement in a 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 running process of the program and to avoid the log file collected at the client side from being excessively large, the log file processing server 12 compresses and encrypts the generated log file.
In particular, during the running process of the program, the engineering files including the log files and other data files may be generated, so that the log file processing server first needs to obtain the log files stored in the engineering files. As shown in fig. 3, a schematic diagram of an engineering file provided in an embodiment of the disclosure is shown, where a white box portion indicates a LOG file included in the engineering file, and the rest is other data files included in the engineering file, and when implemented, a format of the LOG file included in the engineering file is fixed, and in fig. 3, a LOG statement starts with a LOG; the method comprises the steps that the format of the tail end appears, based on the format, preset format storage information can be set, a log file processing server carries out regular matching on engineering files by using regular expressions which are the same as the preset format storage information, a stored log file can be obtained, further, by using the log file, log sentences in the log file can be determined, then the log sentences are analyzed again by using the regular expressions, a fixed data part and a variable data part in the log sentences can be determined, and in addition, when the log sentences stored in the log file are obtained, identifiers corresponding to the log sentences can be generated in a self-increasing mode according to the sequence of the obtained log sentences.
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 stored information ("LOG") in the preset format, to obtain a LOG file LOG (ls_info, app_trival_module) < < "> Request video stream ssrc: "< < ssrc < <" width: "< < width < <" height: "< < height; the method comprises the steps of carrying out a first treatment on the surface of the Further, it may be determined that the log statement in this log file is "" "Request video stream ssrc: "< < ssrc < <" width: "< < width < <" height: "< < height; "; then, the regular expression is utilized to analyze the data, and the unchanged data 'Request video stream ssrc' is determined: "< < <" width: "< < <" height: "<; "as a fixed data portion, the changed data" ssrc, width, height "is determined as a variable data portion, and in addition, assuming that the log statement obtained in this step is the first log statement of the log file, the identifier of this log statement can be determined to be 1.
S202: the log statements in the log file are replaced with the variable data portion and identifiers of the log statements.
In specific implementation, the generated log statement identifier and the determined variable data portion may be combined into a target log statement, in an implementation manner, the log statement identifier may be placed in front of the variable data portion, and taking the log statement in fig. 3 as an example, it may be determined that the combined target log statement is 1, ssrc, width, height; in another implementation manner, the log statement identifier may be placed at the rear of the variable data portion, and the embodiment of the disclosure is not limited with respect to the combination manner of the log statement identifier and the variable data portion in the embodiment of the disclosure, and further, the log statement in the obtained log file is replaced by the combined target log statement.
For example, for the log statement "" "Request video stream ssrc" included in fig. 3: "< < ssrc < <" width: "< < width < <" height: "< < height; and replacing to obtain the replaced target log statement as 1, ssrc, width and height.
S203: the identifiers of the fixed data portions and the log statements are stored in a log statement mapping table that is used to restore the identifiers of the variable data portions and the log statements in the replaced log file to log statements.
In this step, in order to restore the replaced log file, a log statement mapping table for storing identifiers of the fixed data portion and the log statement needs to be generated.
In specific implementation, based on the determined data name corresponding to the variable data portion, determining the position of the variable data in the log statement, and then replacing the variable data portion at the corresponding position in the log statement with a unified data identifier, for example, the unified data identifier may be a placeholder, further, storing the replaced log statement as a fixed data portion and an identifier correspondingly generated in the process of obtaining the log statement as a whole in a log statement mapping table, taking the log statement included in fig. 3 as an example, and using the placeholder to replace the log statement as "Request video stream ssrc: "<%d <" "width": "<%d <" "height": "<% d; the method comprises the steps of carrying out a first treatment on the surface of the Where "%d" represents the placeholder, the data content in the log statement mapping table may be 1, "Request video stream ssrc: "<%d <" "width": "<%d <" "height": "<% d; . Further, after replacing the obtained log statement with the target log statement, the log file processing server compiles the engineering file of the replaced log file normally to generate a preprocessing program only containing the target log statement. Based on the method, even if the preprocessing program is leaked, the analyzed log statement only comprises an identifier and a variable data part, no associated context information exists, and if a log statement mapping table which is not generated is used as a reference, the acquired identifier and the variable data part have no practical meaning, so that the leakage of user information is not caused, and the safety of the log file is ensured.
Further, when the user needs to acquire the stored log file, submitting an operation instruction for the replaced log file to the client, and sending the operation instruction for the replaced log file to the log file processing server by the client according to the operation instruction, wherein the log file processing server further responds to the received operation instruction for the replaced log file to restore the replaced log statement.
As shown in fig. 4, a flowchart for restoring a replaced log statement provided in an embodiment of the disclosure may include the following steps:
s401: in response to an execution instruction for the replaced log file, an identifier of the log statement is obtained from the replaced log file.
In the 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, matches each acquired target log statement by using a regular expression, and can acquire an identifier of the target log statement, wherein the identifier of the target log statement is an identifier of the log statement acquired in the replaced log file. In addition, there is an identifier representing an unsubstituted log statement in the generated log statement map table in correspondence with the obtained identifier of each target log statement.
S402: based on the identifier of the log statement, a fixed data portion of the log statement is obtained from the log statement mapping table.
