Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a log reading method is provided, and this embodiment is applied to a terminal for illustration, where the terminal may be, but is not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices. The method comprises the following steps:
S102, according to the communication connection between the communication module and the host, a login request is sent to the log management program through the log reading program, so that the log management program verifies login information according to a pre-stored user list, and the login request carries the login information.
The terminal comprises a communication module and a host, wherein the communication module and the host can communicate through PCIe (peripheral component interconnect express, high-speed serial computer expansion bus standard) or USB (Universal Serial Bus ). The communication module is a module having a communication function, such as a 4G module, a 5G module. The host computer is provided with a log reading program, and the log reading program is an application program for providing log reading service. The communication module is operated with a log management program, and the log management program is an application program for providing log management service. The log reading program and the log management program interact with each other by exchanging information so as to realize reading of log files in the communication module.
The user list is a table file in which user information is recorded. The user list includes a plurality of sets of data, each set of data including user information of an individual user. The user information includes login information, management authority, and read authority. The login information includes a user account number and a user password. The management authority comprises management authority and no management authority. The user with the management authority is an administrator user or a super user, and can manage the user information of the common user, such as adding users, deleting users and modifying user information. The users without administrative rights are ordinary users. The read rights may be classified according to log levels, for example, the read rights of the user a are the read rights of the log level 1 and the log level 2, which indicates that the user a may read the log file corresponding to the log level 1, the log file corresponding to the log level 2, and the read rights of the user B are the read rights of the log level 1, which indicates that the user B may only read the log file corresponding to the log level 1. The read rights may also be classified according to the user level, for example, the read rights of the user a are high, which indicates that the user a can read the log files corresponding to all log levels (log levels 1-3), the read rights of the user B are medium, which indicates that the user B can read the log files corresponding to the log levels 1-2, and the read rights of the user C are low, which indicates that the user C can only read the log files corresponding to the log level 1. The user list may be pre-burned into the communication module and saved into the memory of the communication module.
Specifically, a log reading program can display a login interface on the host computer, wherein the login interface comprises a login information filling position and a login button. The user may populate a user account and user password in a login information pad location and trigger a login button. When the triggering operation of the login button is detected, the log reading program of the host side generates a login request according to login information filled by a user, and sends the login request to the log management program of the communication module side through PCIe or USB. The log management program at the communication module side can acquire a pre-stored user list, and inquires whether login information carried by the login request exists in the user list. If the login information can be queried in the user list, the login request passes verification. The triggering operation may specifically be a touch operation, a cursor operation, a key operation or a voice operation, the touch operation may be a touch click operation, a touch press operation or a touch slide operation, and the touch click operation may be a single-point touch operation or a multi-point touch operation.

The tag information is description information of the log file, is used for describing attribute information of the log file, and can also be used for identifying the log file. The log file is a log file output by the service program in the communication module, and the log file can be used for analyzing the running state of the service program. The label information of the log file includes creation time, log grade and business program identification of the log file. The creation time of the log file refers to the time when the business program outputs the log file. The log rank of a log file refers to the rank of the log file. The higher the level of the log file, the more important the log file is, which includes sensitive data that is more sensitive. The log grade of the log file can be determined in advance by a developer of the service program, and the developer of the service program can configure log grade rules corresponding to each service program through codes. Based on the log level rule, each business program can output the log level of the log file together when outputting the log file. The service program identifier is an identifier for uniquely identifying a service program, and may specifically include a character string of at least one of letters, numbers, and symbols.
The log management program can receive the log files sent by the service program, encrypt, compress and store the log files. The encrypted log file and the tag information of the log file may be stored in association.
The log file list is a table file in which tag information of log files is recorded. The log file list includes a plurality of sets of data, each set of data including tag information of a single log file.
Specifically, when the login information of the user passes verification, the log management program at the communication module side can acquire the reading authority corresponding to the login information from the user list, and the log grade which can be read by the user can be determined according to the reading authority. The log management program at the communication module side can search a plurality of encrypted log files corresponding to the log grade from the storage area of the log files, acquire the label information of the searched plurality of encrypted log files, and generate a log file list according to the acquired label information. When the login information of the user passes the verification, the log management program at the communication module side can return a verification success message to the log reading program at the host side. When the log reading program of the host side receives the verification success message, the log reading program jumps to the log file reading interface from the login interface.
And S106, according to the communication connection between the communication module and the host, the log file list is sent to a log reading program for display.

The log reading request is a request with a reading function and is used for reading the log file.
Specifically, the communication module and the host have established communication connection, the log management program at the communication module side may send the log file list to the log reading program at the host side, and the log file list may be displayed on the log file reading interface of the log reading program, that is, label information of the log file available for reading is displayed. When the triggering operation of the user on the log file list is detected, namely the user selects at least one piece of tag information through the log file list, the log reading program generates a log reading request according to the tag information selected by the user, and the log reading request is sent to a log management program on the communication module side. After receiving the log reading request, the log management program can acquire a target encrypted log file corresponding to target tag information carried by the log reading request from a storage area of the log file, decompress and decrypt the target encrypted log file, and obtain a target decrypted log file. The log management program at the communication module side can send the target decryption log file to the log reading program at the host side, and the target decryption log file is displayed on a log file reading interface of the log reading program.
In one embodiment, sending, by a log reader, a log read request to a log manager includes: acquiring at least one piece of tag information selected from a log file list as target tag information through a log reading program; generating a log reading request according to the target tag information through a log reading program, and sending the log reading request to a log management program.
Specifically, after the log reading program at the host side obtains the log file list, the log file list may be displayed through the log file reading interface, and the user may select at least one tag information as the target tag information through the log file reading interface, so that the log reading program may generate a log reading request according to the target tag information, and send the log reading request to the log management program at the communication module side. In this way, compared with the method that the log reading program directly generates and transmits the log reading request to the log management program, in the embodiment, after the target tag information is determined, the log reading request is generated according to the target tag information, and then the log reading request is transmitted to the log management program, so that the data volume transmitted between the host side and the communication module side can be reduced, and the log reading efficiency is improved.

Therefore, before the user obtains the log file from the host side to the communication module side, the communication module side checks the identity information of the user through the log management program, and when the identity information passes the check, the user is indicated to be a safe user, the safe user can obtain the log file, and the safety of reading the log file is improved. Moreover, different users can acquire log files of different grades, so that the security of log file reading is further improved. In addition, the encryption and decryption processes of the log file are realized at the communication module side, so that the risk of cracking an encryption algorithm is reduced, and the security of reading the log file is further improved.
