Example 1
Referring to fig. 1, an embodiment 1 of the present invention provides a method for managing a server operation log based on HTTP, where the method includes a log writing process, where the log writing process includes the following steps:
a1, locking the log file, and only allowing the current user to write the log file;
a2, obtaining the size of a log file, judging whether the size of the log file reaches a set value of the file size, if so, setting a first recording mode, wherein the first recording mode is to use the latest working record to cover the earliest working record, and if not, setting a second recording mode, wherein the second recording mode is to continue to add the latest working record in the log file;
a3, unlocking the log file;
a4, closing the log file.
In the present invention, before step a1, there is also a start step a 0: after an application program triggers log records, identifying whether log files exist or not, namely, opening the log files if the log files exist, and if the log files do not exist, creating the log files;
after an application program triggers log recording, whether a log file exists or not is firstly identified, if the log file does not exist, the log file for recording the working condition of the application program needs to be created, if the log file exists, the log file is opened, and it needs to be noted that the log file can be stored in a nonvolatile Flash, and when the log file is opened, the log file is opened in an additional mode, namely the existing content of the log file is not cleared, but the content is newly added after the existing content of the log file;
in step a1, in order to ensure that the log file is not modified by multiple users when it is opened, the log file is locked, so that the log file is only allowed to be written by one user each time, and other users need to wait until the log file is unlocked to rewrite the log file;
in step a2, obtaining the size of the log file, and determining whether the size of the log file reaches a file size set value, where the file size set value is a preset value, and if the file size set value reaches the set value, setting a first entry mode, where the first entry mode is to use the latest work record to cover the earliest work record, and if the file size set value is not reached, setting a second entry mode, where the second entry mode is to continue to add the latest work record in the log file;
then in steps A3 and A4, after the latest work record is recorded in the log file, the log file is unlocked so as to be operated later, and after the operation is finished, the log file is closed;
the method locks the log file, selects an entry mode according to the size of the log file, then enters the current server operation instruction into the log file, unlocks the log file, and finally closes the log file.
The invention carries out detailed log recording on the log file, avoids interference of other users and ensures the smooth operation of log management.
When necessary, the invention can also automatically convert the corresponding language according to the language format of the BMC Web interface to describe the relevant operation record, is convenient to expand and is beneficial to internationalization.
Example 2

b3, extracting the readable formatted working record to be viewed in a json form, and returning an HTTP response to the web browser end for processing and displaying;
b4, closing the log file;
in the present invention, before step B1, there is also a start step B0: acquiring a log file extracting instruction, and starting the operation of extracting the log file after receiving the log file extracting instruction;
in step B1, the log file is opened in a read-only manner, thereby avoiding modification of the contents of the log file;
because a large amount of data may exist in the log file, step B2 needs to be performed to establish a start index and an end index, so that after determining the range of the work record to be read in the file according to the start index and the end index, the records of the total record size to be checked are read, and readable formatting operation is performed on each work record in sequence;
and then, storing the readable formatted working record in a json form, returning a response to the web browser end through HTTP for processing and displaying, and closing the log file after consulting.
It should be noted that the json format is more convenient and more efficient in parsing than other formats.
The embodiment is a log reading process, changes to the log file are avoided in a read-only mode, simultaneous reading of multiple users is supported, convenience can be provided for the lookup work by establishing the initial index and the termination index, and the work efficiency is improved.
It should be noted that, when the start index and the end index are established, the range of the work record to be viewed in the log file is determined, the total number of the work records to be viewed is obtained, and each work record to be viewed is subjected to readable formatting in sequence:
the operation records are sequentially subjected to readable formatting from the last record to the first record extracted according to the reverse order, so that the operation records executed later can be displayed on the web firstly;
in addition, only English and Chinese are currently supported according to the language format of the current WEB interface, and the recorded content can be automatically converted into the language format corresponding to the WEB interface according to the newly added language required subsequently.
