[0041] In order to make the personnel in the technical field better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the personnel in the technical field without creative labor fall within the scope of protection of the present application.

[0042] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced without the specific details, which are not described in the present application, and the personnel in the technical field can make similar generalizations without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0043] With the continuous upgrading and large-scale popularization of computer networks, the types of services provided by the Internet are more and more various and rich. At present, users access the Internet by using browsers or other client agents. The browser is convenient, fast and easy to operate, and a large number of users use the browser to obtain Internet services. The browser provides network services based on a website (WEB) server. At present, there are various WEB servers on the market. Each server adopts different ways to realize object component support, distributed computing, deployment speed and ease of use. At present, the WEB servers mainly include the following: IIS, Nginx and Apache.

[0044] However, the above WEB servers have disadvantages, for example, IIS adopts a single-point deployment mode. If a certain site needs to be modified or deleted, the entire system needs to be re-deployed, which is relatively high in cost. The configuration and management of IIS are relatively cumbersome, which needs to be realized through a command line or a script, resulting in difficult construction. Nginx needs to install multiple modules to meet various needs, that is, the construction cost is high. Apache has high maintenance cost.

[0045] That is, although the WEB server can share various different media resources on the Internet, the same WEB server has less functions and cannot provide low-cost and comprehensive network services. At present, there is a demand for constructing a network service with specific functions or small size. However, the network service constructed based on the current server architecture has high cost and a relatively complex construction process, which cannot meet the demand for providing network services quickly and at low cost.

[0046] Based on this, the application provides an access method, applied to a website server, the website server comprising a main process, a plurality of sub-processes and a common gateway interface, that is, the architecture of the website server is composed of the main process and the plurality of sub-processes, the architecture is simple and relatively easy to build, the method comprising: the main process receiving a hypertext transfer protocol request sent by a terminal device, forwarding the hypertext transfer protocol request to a target sub-process, the target sub-process being any one of the plurality of sub-processes that has not processed the request, the target sub-process performing message analysis on the hypertext transfer protocol request to obtain request resource information corresponding to the hypertext transfer protocol request, that is, the website server is based on a hypertext transfer protocol (HTTP) transmission request and a resource requested by the terminal device, so that the website server can provide a network access service based on a browser. The website server uses the main process to receive the request and uses the sub-process to process the request, thereby realizing concurrent processing of the request and improving the efficiency of the network access service. The common gateway interface is used to send a target request for obtaining the request resource information to an external expansion server, and a target resource obtained by the external expansion server by calling a custom function to process the target request is received, that is, the website server can communicate with the external expansion server through the common gateway interface, thereby expanding the network service function of the website server and realizing better network service. The target sub-process generates a response message using the target resource, and the main process sends the response message to the terminal device, finally realizing resource feedback to the terminal device. As can be seen, the website server based on the main process and the plurality of sub-processes can be used to provide a network access service, the website server has a simple architecture, is easy to build and has a low cost, and can also use the common gateway interface to expand the function of the network service, thereby meeting the demand for providing a network service quickly and at a low cost.

[0047] In order to better understand the technical solutions and technical effects of the application, specific embodiments will be described in detail below with reference to the drawings.

[0048] Referring to Figure 1 , the figure is a flowchart of an access method provided by an embodiment of the application.

[0049] The access method provided by the embodiment of the application is applied to a website server, and the website server comprises a main process, a plurality of sub-processes and a common gateway (CGI) interface. Referring to Figure 2 , it is a schematic diagram of a website server architecture provided by an embodiment of the application. The website server adopts a synchronous blocking mode, that is, the website server can be divided into a main process and a sub-process, the main process and the sub-process respectively undertake different functions of the website server and cooperate with each other.

[0050] The main process is mainly responsible for: initializing loading various parameter configurations, daemon process and log processing, message receiving and forwarding. The sub-process is mainly responsible for: request processing. That is, the main process is responsible for various underlying basic businesses, and the sub-process is responsible for core businesses. Such allocation of tasks of the main process and the sub-process can modularize different functions, and can also facilitate debugging of the website server, so as to realize a website server which is relatively easy to build and low in cost.

[0051] In the embodiment of the application, the website server is constructed by using C language, and provides network access services based on HyperText Transfer Protocol (HTTP). HTTPS is a secure version of HTTP. The purpose of HTTP is to enable the website server to be accessed by a browser, and provides some basic functions, such as file download, image display, and the like. That is, the website server is responsible for processing HTTP requests and returning responses to terminal devices. The website server can accept HTTP requests from terminal devices including browsers, and generate corresponding HTML pages or other format documents according to the request content, and then sends them back to the terminal devices.

[0052] The common gateway interface can realize communication between the website server and the external extension server. When the website server cannot provide a certain network service, the external extension server can be used to provide the network service, that is, the website server can communicate with the external extension server through the common gateway interface, so as to expand the network service function of the website server and realize better network service.

[0053] Reference Figure 3 As shown in the figure, it is a network service framework schematic diagram provided by the embodiment of the application. The terminal device is a WEB client, which can be a browser for example. The WEB client can be a website client application program. The website server can be a WEB server, which can be a website server application program. The WEB server can include an external extension (FastCgi) client application program. The FastCgi client communicates with the FastCgi server through the common gateway interface, and the FastCgi server can be an external extension application program.

[0054] The WEB server can also include a plurality of modules, such as a server configuration reading and loading module, a limit access configuration reading and loading module, an HTTP message receiving and parsing module, and a request resource input and output (I / O) processing module. The request resource input and output processing module can include a directory part, a dynamic file part, a static file part, and a FastCgi client.

[0055] Before the website server runs, server configuration reading and access restriction configuration reading are performed, that is, server configuration and access restriction rule configuration are loaded. After the two configuration files are loaded into the website server application, a socket application process is performed, and then a socket programming interface is listened to, HTTP requests are received and processed.

[0056] After the website server starts running, the received HTTP request is forwarded to the HTTP message receiving and parsing module for processing. The HTTP message receiving and parsing module obtains the required information by parsing the message field of the HTTP request, and uses the obtained information to automatically determine the resource type of the HTTP request through the request resource I / O processing module, and calls the processing function of the corresponding resource type to transmit the requested resource. If the website server cannot provide the requested resource, the external expansion server can be used to provide the resource. Specifically, the external expansion client and the external expansion server can be interacted.

[0057] Reference Figure 4 As shown in the figure, an external expansion server architecture provided by the embodiment of the application is shown. The external expansion server includes a control (Master) process and a plurality of worker (Worker) processes. The Master process is a main process, mainly responsible for receiving and forwarding CGI messages. The Worker process is a sub-process, mainly responsible for processing CGI requests, such as message parsing of the CGI request, calling a custom function, and returning the processing result to the main process. The custom function can also be called a user-defined action function, which is configured by the user and can be configured according to the function of the network service.

[0058] Since the external expansion server adopts a process pool structure, the control right is on the Master process. The Master process manages all Worker processes. After the external expansion server starts running, the Worker processes are always resident in the memory and wait for request processing at any time, which can realize efficient request processing of the external expansion server. The user-defined function adopts the form of a function pointer, which is convenient for mapping the function name to the specified calling function.

[0059] The access method provided by the embodiment includes the following steps:

[0060] S101, the main process receives the hypertext transfer protocol request sent by the terminal device, and forwards the hypertext transfer protocol request to the target sub-process.

[0061] In the embodiments of the present application, the main process of the website server can receive the HTTP request sent by the terminal device, and forward the HTTP request to the target sub-process. In view of the factor of quickly processing the request, the main process can select any one of the sub-processes which have no request to process when forwarding the HTTP request, so that the idle sub-process can be used to process the HTTP request in time. That is, any one of the sub-processes which have no request to process is the target sub-process.

[0062] The website server can further include a socket programming interface, and the main process can receive the HTTP request sent by the terminal device by using the socket programming interface. The socket programming interface is obtained by initializing the socket corresponding to HTTP / HTTPS of the website server.

[0063] Specifically, before the website server provides the network service, the main process can load the server configuration of the website server, and initialize the socket programming interface for receiving the HTTP request.

[0064] S102, the target sub-process performs packet analysis on the HTTP request to obtain the request resource information corresponding to the HTTP request.

[0065] In the embodiments of the present application, after receiving the HTTP request forwarded by the main process, the target sub-process can perform packet analysis on the HTTP request to obtain the request resource information corresponding to the HTTP request.

[0066] In actual application, after obtaining the request resource information, the target sub-process can call the target function to process the HTTP request to obtain the target resource, so that the response packet can be generated according to the target resource, and the request processing is ended. The target function is a function defined in advance in the server configuration, and the target function can obtain the target resource.

[0067] S103, a target request for obtaining the request resource information is sent to the external expansion server through the public gateway interface, and the target resource obtained by calling the custom function to process the target request by the external expansion application is received.

[0068] In the embodiments of the present application, considering that the preconfigured target function can not be able to handle the hypertext transfer protocol request, the external expansion server can be utilized to continue the request processing, so as to obtain the target resource. The website server can send a target request for obtaining the request resource information to the external expansion server through the common gateway interface, where the target request can be a CGI message. After receiving the target request, the external expansion server can call a custom function to process the target request to obtain the target resource, and return the target resource to the website server. The target resource meets the request resource information.

[0069] Since the external expansion server includes a control process and a plurality of working processes, the website server can send a target request for obtaining the request resource information to the control process through the common gateway interface, the control process forwards the target request to the working process, the working process calls a custom function to process the target request to obtain the target resource and returns the target resource to the control process, and the control process returns the target resource to the target sub-process of the website server.

[0070] When the control process forwards the target request to the working process, an idle working process can be selected, so as to realize efficient target request processing.

[0071] In the embodiments of the present application, when the target request is processed by the custom function to obtain the target resource, the selected custom function is determined according to the request resource type included in the request resource information, and the obtained target resource meets the request resource type.

[0072] S104, the target sub-process generates a response message by using the target resource, and the main process sends the response message to the terminal device.

[0073] In the embodiments of the present application, after obtaining the target resource, the target sub-process can generate a response message by using the target resource and send it to the main process, and the main process sends the response message to the terminal device, so as to realize the access response of the terminal device.

[0074] In the embodiments of the present application, the website server can also limit the access of the terminal device, that is, the website server can also configure an access control function. Specifically, a limit access configuration file can be obtained, and it is determined whether the target resource meets the limit access condition of the terminal device according to the limit access configuration file. If yes, a response message that the terminal device cannot access is returned to the terminal device.

[0075] The limit access configuration file includes a preconfigured limit field, the limit field constitutes a limit access condition, and the limit access condition is used to control the access of the terminal device to the target resource, so as to improve the control of the website server on the resource.

[0076] It can be seen that the access method provided by the embodiment of the application is based on a website server, the website server has low development cost, is easy to maintain and expand, and has good portability. The architecture of the main process and the plurality of sub-processes can be used to build small WEB applications, such as personal blogs or online stores. Since the website server is implemented based on standard HTTP and HTTPS, the website server has high security.

[0077] Based on the access method provided in the above embodiment, the embodiment of the application further provides an access system, and the working principle thereof will be described in detail below with reference to the drawings.
