[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Combine the following Figure 1-Figure 4 The log file generation method of the present invention is described.

[0046] See also Figure 1 , Figure 1 is a flow chart of the log file generation method provided by the present invention, Figure 1 The log file generation method shown can be applied to a Web server, such as Figure 1 As shown, the log file generation method at least includes:

[0047] 101. In response to receiving a service request from a client, the service request is processed to obtain processing information corresponding to the service request.

[0048] In an embodiment of the present invention, a Web server is used to connect with a client, receive a service request sent by a client through a Web browser, process the service request, and feed back the processing result to the Web browser. Usually, a Web server uses Hyper Text Transfer Protocol (HTTP) to exchange information with a client, so the Web server can also be called an HTTP server. A Web server can be a physical server including an independent host, a virtual server carried by a host cluster, a cloud server, etc. The embodiment of the present invention does not limit the implementation method of the Web server. A Web server can be a server applied to different scenarios, and the embodiment of the present invention does not limit the application scenario of the Web server. After receiving the service request from the client, the Web server will process the received service request and obtain the processing information corresponding to the service request. The processing information corresponding to the service request can be recorded by the system as log information.

[0049] 102. Based on a pre-generated hash table, perform data analysis on the processing information corresponding to the service request to generate a log file corresponding to the service request; wherein the hash table is generated based on pre-analysis of a template file of a log center.

[0050] In an embodiment of the present invention, after the Web server processes the received service request and obtains the processing information corresponding to the service request, the processing information corresponding to the service request can be parsed according to the hash table generated by pre-templating the template file of the log center, and a log file that meets the requirements of the template file of the log center can be generated. Among them, the template file is a file configured according to the log format required by the log center. The log center may include different log centers connected to the Web server. Since the log formats defined by different log centers are different, different log centers have different template files. By parsing the different template files of different log centers, hash tables corresponding to different log centers can be generated. According to the hash tables corresponding to different log centers, the processing information corresponding to the service request can be parsed, and log files that meet the requirements of the template files of different log centers can be generated respectively.

[0051] 103, sending the generated log file to the log center.

[0052] In an embodiment of the present invention, after generating a log file that meets the requirements of the template file of the log center, the Web server can send the generated log file that meets the requirements of the template file of the log center to the corresponding log center, and the log center will perform corresponding analysis and processing on the log file, and uniformly monitor and manage the equipment.

[0053] The log file generation method provided by the embodiment of the present invention can generate a log file that conforms to the template file of the log center by performing template parsing on the template file in the log and generating a hash table. According to the generated hash table, data parsing is performed on the processing information corresponding to the service request, so that the log file of the outbound log center does not need to adapt to the log format of the log center by modifying the relevant code for outbound log sending. As long as the log information is obtained and the generation of the log file is controlled by parsing the template file of the log center, the log file that conforms to the template file of the log center can be obtained. When it is necessary to change or add a field in the log format, it is only necessary to change or add the corresponding field in the template file to realize the modification of the log file format without modifying any relevant code. The stability of the Web server can be enhanced, the flexibility of the connection between the Web server and the log center can be enhanced, and it is more convenient.

[0054] See also Figure 2 , Figure 2 It is a schematic diagram of the process of generating a hash table by template parsing provided by the present invention, such as Figure 2 As shown, generating a hash table based on pre-template parsing of the template file of the log center includes at least:

[0055] 201, obtain the template file of the log center.

[0056] 202 , parse the template file to generate a hash table, where the hash table includes a Key field and a Value field, wherein the Key field in the hash table is determined based on the log component items in the template file.

[0057] In an embodiment of the present invention, when the Web server is started, a template file of the log center can be obtained from the log center, and the obtained template file of the log center can be template parsed to generate a corresponding hash table; or, when the Web server is connected to the log center, the template file of the log center can be obtained from the log center, the obtained template file of the log center can be stored, and when the Web server is started, the stored template file of the log center can be template parsed to generate a corresponding hash table; or, when the Web server is connected to the log center, the template file of the log center can be obtained from the log center, and the obtained template file of the log center can be template parsed to generate a corresponding hash table; the embodiment of the present invention does not limit the implementation method of the Web server obtaining the template file of the log center and performing template parsing on the template file to generate a hash table.

[0058] In the embodiment of the present invention, the hash table is a data structure that is directly accessed according to the key code value, that is, the Key-value pair. That is to say, it can speed up the search by mapping the key code value to a position in the table to access the record; therefore, the hash table includes a Key field and a Value field, wherein the Key field in the hash table can be determined according to the log component items in the template file when the template file is parsed, for example, the log component items in the template file can be host, uri, user name, device name, etc.; the Value field in the hash table can be determined according to the real data value obtained by the data parsing when the processing information corresponding to the service request is parsed according to the hash table. For example, the real data value obtained by parsing the processing information is qax.com, / syslog / log, huang, ID19865, etc., wherein the host is qax.com, the uri is / syslog / log, the user name is huang, and the device name is ID19865; after determining the Key field and the Value field in the hash table, the log file corresponding to the service request can be generated according to the hash table at this time.

[0059] In some optional examples, if the log center needs to modify the original log format, for example, add some new structures and data to the original log format, it only needs to add the corresponding structure and the corresponding variable value position in the template file, and send the modified template file to the Web server. The Web server replaces the original template file stored in the log center according to the received modified template file, and performs template parsing on the modified template file to generate a hash table. The log file in the required log format can be generated according to the hash table generated at this time. There is no need to make any modifications to the Web server code, and the log format can be modified at will. therefore Before parsing the template file and generating a hash table, the Web server can also receive a template file sent by the log center and update the template file of the log center stored locally according to the received template file; wherein the template file sent by the log center is obtained by modifying the template file of the log center stored locally.

[0060] In some optional examples, the template file can define the data types in the log file, for example, the defined data types include: standard variable types, special variable types and fixed information types; the standard variable types can be standard variables in HTTP requests, such as the requested host, uri, etc.; the special variable types can be special variables generated in the Web server, such as the user name, application name, device information, etc. in the login request; fixed information types, such as the device name where the identification platform is located, etc. These three data types can almost cover all data types reported by the web server log.

[0061] When performing template parsing on a template file to generate a hash table, a hash table can be generated according to the data type defined in the template file by performing template parsing on the template file. When performing data parsing on processing information corresponding to a service request according to the hash table to determine the Value field in the hash table, data parsing on processing information corresponding to the service request can be performed according to the hash table according to the data type defined in the template file to determine the Value field in the hash table.

[0062] For example, when performing template parsing to generate a hash table for a template file, a hash table can be generated for standard variable types and a hash table can be generated for special variable types, so that all standard variables in HTTP requests obtained by data parsing are stored in a hash table, such as the hash table of ngx.var, and all special variables generated in the Web server obtained by data parsing are also stored in a hash table, such as the hash table of ctx.var. When performing data parsing on processing information corresponding to a service request, different types of data can be distinguished according to the prefix of the data type defined in the template file; for example, the prefix "ngx-" represents standard variable data in HTTP requests, the prefix "ctx-" represents special variable data generated in the Web server, and the prefix "v-" represents fixed information; the data level can be identified by ".", such as "ab" represents the value of key b in hash table a, that is, a[b]; in this way, ngx-host in the template file will be parsed as the value of ngx.var[host], ctx-user.name will be parsed as the value of ctx.var[user][name]; v-ID15672 will be directly parsed as ID15672.

[0063] In some optional examples, template parsing of template files can be performed through plug-ins to generate hash tables, so as to utilize the high extensibility of the plug-in and facilitate adapting to the needs of template parsing of different template files.

[0064] See also Figure 3 , Figure 3 FIG. 1 is another flow chart of generating a hash table by template parsing provided by the present invention, such as Figure 3 As shown, the hash table is generated based on the template parsing of the template file of the log center in advance, which at least includes:

[0065] 301, get the Json file of the log center.

[0066] 302. Based on the hierarchical structure of the Json file, the Json file is template parsed through the plug-in to generate a hash table, where the hash table includes a Key field and a Value field, wherein the Key field in the hash table is determined based on the log component items in the Json file, and the hierarchical structure of the hash table corresponds to the hierarchical structure of the Json file.

[0067] In the embodiment of the present invention, since the Json format has good versatility and readability, the template file can be a Json file. When the template file is parsed, the Json file can be parsed through a plug-in according to the hierarchical structure of the Json file to generate a hash table. At this time, the hash table structure is the structure of the Json file, and the Key field in the hash table is determined according to the Key field in the Json file. At this time, the log file is also a Json file. When generating a log file corresponding to a service request based on the hash table, the hash table can be converted into a Json file as the log file corresponding to the service request.

[0068] In some optional examples, the Web server can use the Openresty framework, which is a high-performance service framework based on Nginx and Lua. It integrates a large number of sophisticated Lua libraries, third-party modules, and most dependencies. It is used to easily build dynamic Web applications, Web services, and dynamic gateways that can handle ultra-high concurrency and high scalability. The Web server can be secondary developed based on the Openresty framework to obtain a Web server that meets the requirements of specific application scenarios. The template parsing and hash table generation plug-in for the template file is written in Lua scripting language.

[0069] See also Figure 4 , Figure 4 is a schematic diagram of an application scenario of the log file generation method provided by the present invention, such as Figure 4 As shown, when the Web server is started, the template file of the log center is obtained from the log center connected to the Web server. Only one template file is shown in the figure, and the dotted line indicates that the template file here can be a template file of different log formats of multiple log centers connected to the Web server. The obtained log file is parsed by template to generate a corresponding hash table, which is stored in the memory. When the Web server receives the HTTP service request from the client, it will process the service request to obtain the processing information corresponding to the service request. The processing information corresponding to the service request is transmitted to the back-end service of the Web server, and the corresponding service will be provided for the service request through the back-end service.

[0070] During the transmission of the processing information corresponding to the service request to the back-end service, the processing information corresponding to the service request can be obtained, and the processing information corresponding to the service request can be parsed through the hash table stored in the memory of the Web server to generate a log file corresponding to the service request. A log file is generated for each service request, and the generated log file is sent to the corresponding log center for analysis and processing.

[0071] The log center needs to analyze the logs reported by the Web server, so the reported logs need to have a specific format and corresponding information. The following is an example of the basic information of an application being accessed and the log of the accessing user that the log center needs to report:

[0072]

[0073] After the Web server is connected to the log center, you need to configure the corresponding template file and restart the Web server to generate corresponding log files according to different requests. The following is an example of the corresponding template file configured:
