It can be connected by a special encrypted communication protocol, and a private communication line is established between two or more intranets located at different places on the Internet. Generally, after a terminal in a VPN network starts a VPN service, all network requests in the terminal are acquired by a virtual network card and sent to a VPN server, the VPN server receives the network request of the terminal and analyzes the network request, and then forwards the network request to a corresponding target server according to an analysis result, and receives data returned by the target server.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
An embodiment of the present invention provides a method for processing a network request, where as shown in fig. 1, the method is applied in a terminal capable of using a VPN network service function to implement analysis processing of a network request generated by the terminal locally at the terminal, and for this, the following specific steps are provided in the embodiment of the present invention:
101. and acquiring a network request of the terminal application in the VPN network.
At present, after a VPN service is opened in a terminal, a system automatically intercepts network requests generated by all applications in the terminal, and all the network requests are sent to a VPN server for uniform analysis processing. Specifically, a virtual network card is created in the terminal, the virtual network card is used for communication connection between the terminal and the VPN server, and the virtual network card acquires network requests of all applications in the terminal. In this step, the characteristics of the network requests of all applications in the terminal, which can be obtained by the virtual network card when the VPN service is opened, are also utilized, and the network requests intercepted by the virtual network card are directly obtained under the condition that the VPN service is opened. These network requests include network requests of the terminal system itself and network requests of third party applications installed on the terminal.
102. And storing the network request into a cache of the terminal.
When the virtual network card of the terminal acquires the network request, the terminal caches the network request, and the embodiment of the invention does not limit the specific caching mode, and the network request can be directly extracted from the virtual network card and stored in the cache of the terminal, or the network request acquired by the virtual network card can be copied and stored in the cache of the terminal.
It should be noted that, when caching network requests, the embodiments of the present invention do not limit the number of cached network requests, and may only cache one network request, delete the network request after the resolution is completed, and cache the next network request, or establish a queue in the terminal cache, cache the network requests in the queue, and perform resolution processing one by one.
103. And analyzing according to the message format of the network request in the terminal cache to obtain the analysis result of the network request.
The format of the network request refers to a manner of interaction between the client and the server, for example, the network request manner included in the http protocol is to search, modify, add, and delete network resources, that is, get, post, put, and delete. According to the specific format of the network request, the network request data is analyzed in different ways, so as to obtain a corresponding network request analysis result, that is, relevant parameter data in the network request, such as an address and a port number of an access target server, a type, a date, a size and the like of the request data, is obtained.
Generally, the network request is transmitted in the form of a message, and different network requests may adopt different message formats, such as an IP message, a TCP message, a UDP message, and the like.
104. And carrying out statistics and presentation on the obtained analysis result.
In this step, the analysis result obtained in step 103 is analyzed locally at the terminal, for the parameter data to be counted, the corresponding data in the extracted analysis result and the existing data are summarized and counted, and for the parameter data to be displayed, the corresponding data content is visually output according to the specific format to be displayed. The specific way of statistics and presentation is not the focus of the embodiment of the present invention, and the implementation way is not limited to one of the existing applications. In this step, what should be embodied is that the analysis result of statistics and presentation is obtained from the local terminal, and it is not necessary to obtain the corresponding data content from the VPN server.
It can be seen from the foregoing implementation manner that, in the method for processing a network request according to the embodiment of the present invention, when the VPN service is opened, the network request sent by the terminal application is acquired, the analysis operation is completed locally at the terminal, the analysis result is displayed in the terminal, and meanwhile, according to the obtained analysis result, the target server to be accessed by the network request can be determined, and the network request is sent to the target server. Compared with the network request processing mode under the existing VPN service, the embodiment of the invention realizes the localized analysis and display of the network request, so that the analysis result of the network request to be displayed is not required to be obtained from a VPN server, but the analysis result can be directly obtained from the terminal, and the response rate of the terminal in counting and displaying the local network request analysis result is improved. In addition, for the VPN server, the VPN server is not required to return the analysis result of the network request to the terminal, so that the processing pressure of the VPN server can be reduced, and the bandwidth resource occupied by sending the analysis result is reduced.
In order to describe the processing method of a network request in more detail, particularly a specific processing manner of the network request locally at the terminal after the VPN service is opened, as shown in fig. 2, the method includes the following steps:
201. and acquiring a network request of the terminal application in the VPN network.
And acquiring network requests of all applications in the terminal by using the virtual network card established in the terminal. The main content of this step is the same as step 101 in the above embodiment, and reference may be made to the above step for details, which are not described herein again.
202. And storing the network request into a cache of the terminal.
The content of this step is the same as that of step 102 in the above embodiment, and reference may be made to the above step specifically, which is not described herein again.
203. And analyzing according to the message format of the network request in the terminal cache to obtain the analysis result of the network request.
Firstly, to analyze a network request, a network request needs to be acquired first, and in the embodiment of the invention, the cached network request is extracted from a cache of a terminal, namely a request message of the network request is extracted.
Next, the message format of the extracted network request is determined, in the embodiment of the present invention, an HTTP request message is described as an example, one HTTP request message is composed of 4 parts, namely, a request line (request line), a request header (header), a null line, and request data, as shown in fig. 3, and is a general format of a request message, wherein the request line is composed of 3 fields, namely, a request method field, a URL field, and an HTTP protocol version field, which are separated by a space. Html HTTP/1.1, for example GET/index. The HTTP protocol request method includes GET, POST, HEAD, PUT, DELETE, OPTIONS, TRACE, CONNECT. The most common GET and POST methods are described here; the request header consists of key/value pairs, one pair per row, with the key and value separated by the english colon ": to. The request header informs the server about the information requested by the client, and typical request headers are: User-Agent: browser type of the generation request, Accept: a content type list which can be identified by the client, Host: the requested host name, which allows a plurality of domain names to be co-located with one IP address, namely a virtual host; an empty line is arranged behind the last request head, and the return character and the line feed character are sent to inform the server that no request head exists below the server; the request data is not used in the GET method but is used in the POST method. The POST method is suitable for occasions where customers are required to fill in forms. The most commonly used request headers associated with the requested data are Content-Type and Content-Length.
As can be seen, determining the message format of the network request is to obtain data information of each component in header information of the request message, where the main data information for distinguishing the message format includes: version of the message, protocol, source address and port number, and destination address and port number, etc. In this regard, the present invention implements pseudo code that provides for obtaining data information in a request message in a java environment:
version＝(byte)(buffer.get()>>4)；
protocolNum＝(short)(buffer.get()&0xFF)；
protocol＝getProtolByNum(protocolNum)；
byte[]addressBytes＝new byte[4]；
buffer.get(addressBytes,0,4)；
destinationAddress＝InetAddress.getByAddress(addressBytes)。
the process of executing the pseudo code mainly determines the version number of the IP protocol according to the head 4 bits of the request message, namely, the version is judged to be IP v4 or IP v6, the currently used version is IP v4, and the data value is 0100; acquiring 5-12 bits of data to judge the type of the adopted protocol, such as tcp protocol, udp protocol and the like; and then acquiring 32 bits occupied by the target address, namely 4 bytes of data, and converting the byte array addresses into IP addresses by using a function provided by java, namely the target address.
In practical application, often, while determining the format of the network request message, the relevant parameter data in the network request can be obtained according to the content and the position of different fields in the message, that is, the analysis of the network request is performed.
And finally, analyzing the network request according to the determined message format to obtain an analysis result of the network request. According to the above example, the purpose of determining the format of the network request message is to determine the field allocation of each part in the message, and the analysis of the network request message is a process of converting by acquiring data of each part of the field. That is, the data of the fields at different positions in the message are obtained according to the message format, so as to obtain the relevant parameter data contained in the network request.
204. And carrying out statistics and presentation on the obtained analysis result.
The content of this step is the same as step 104 in the above embodiment, and reference may be made to the above step specifically, which is not described herein again.
205. And sending the network request to a target server according to the analysis result of the network request.
Because the network request can be analyzed in real time locally at the terminal and the relevant parameter data of the network request can be obtained, the embodiment of the invention can carry out local operation on the network request based on the characteristics. For example, the address of the target server to which the network request is to be accessed can be known from the target address information of the analysis result, and the network request can be directly sent to the target server without being forwarded through the VPN server when the VPN service is opened according to the address. Therefore, the network request to be processed sent by the terminal to the VPN server can be reduced, so that the workload of the VPN server is introduced, meanwhile, due to the network request directly sent by the terminal, the data information fed back by the target server aiming at the network request is also directly returned to the terminal without being forwarded by the VPN server, and the network request processing efficiency and the response speed are improved.
In addition, before sending the network request to the target server, the connectivity of the target server can be judged to determine that the target server can be accessed without the VPN server. In this regard, the embodiments of the present invention are not limited to using PING commands to determine connectivity of target servers, or to setting a server white list in advance to define target servers that can be directly accessed.
Further, as an implementation of the foregoing method, an embodiment of the present invention provides a device for processing a network request, where the embodiment of the device corresponds to the foregoing method embodiment, and for convenience of reading, details in the foregoing method embodiment are not described in detail again in this device embodiment, but it should be clear that the device in this embodiment can correspondingly implement all the contents in the foregoing method embodiment.
