Method used

2, adopt agent mode to realize, analyze the message received by external port network agent, thereby forward to the port on the internal different agreement, such implementation mode simplifies realization, is more conducive to the old system simultaneously expand.

[0036] In the technical solution of the present invention: TCP: Transmission Control Protocol (Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol. TLS: Transport Layer Security (TransportLayer Security), its predecessor is Secure Sockets Layer (Secure Sockets Layer, abbreviated as SSL) is a security protocol, the purpose is to provide security and data integrity guarantee for Internet communication. http: Hypertext Transfer Protocol (HyperTextTransfer Protocol), is a request ...

Abstract

The invention discloses a network protocol internal proxy forwarding method. The method comprises the following steps: receiving and obtaining a request message sent from a client application program;analyzing the request message to obtain a message format; distinguishing a message protocol to carry out forwarding processing according to the message format; performing service processing accordingto the content of the distinguishing protocol. According to the invention, a plurality of protocols are supported to be completed in one port; through judging message format, the used protocols are distinguished and forwarded to different functional modules to be processed, so that the technical problems that a traditional one-to-one port connection method adopted for connection between an application and a server is complex and a user inconveniently uses the protocols are solved, the support of multiple message protocols on the same port is realized, and the use convenience of the user is further improved.

Example Embodiment

[0050] Embodiment 1, the client application sends the message that contains the TLS domain and adopts the https protocol to the server;

[0051] will go through the following steps:

[0052] 1. The client application sends a request https message;

[0053] 2. After the server application receives the message, it parses the message;

[0054] 3. The server application program forwards according to the message format, distinguishing the protocol;

[0055] Specifically: the packet contains TLS protocol packets, and TLS unpacking is performed. After unpacking, it is distinguished that the data field in the packet is a packet using the http protocol; the data field in the packet adopts the http protocol, which is forwarded to the http module for processing;

[0056] 4. The server-side application performs business processing.

Example Embodiment

[0057] Embodiment 2, the client application sends a TCP message to the server, which does not contain a message in the TLS domain;

[0058] will go through the following steps:

[0059] 1. The client application sends a request TCP message;

[0060] 2. After the server application receives the message, it parses the message;

[0061] 3. The server application program forwards according to the message format, distinguishing the protocol;

[0062] Specifically: the message does not have a TLS protocol message, and the data field in the message is a non-http protocol message; the data field in the message is a non-http protocol message, which is forwarded to the TCP module for processing;

[0063] 4. The server-side application performs business processing.

Example Embodiment

[0064] Embodiment 3, the client application sends the http message to the server, which does not contain the message of the TLS domain;

[0065] will go through the following steps:

[0066] 1. The client application sends a request http message;

[0067] 2. After the server application receives the message, it parses the message;

[0068] 3. The server application program forwards according to the message format, distinguishing the protocol;

[0069] Specifically, if the message has no TLS protocol message, it is distinguished that the data field in the message adopts the http protocol message; the data field in the message adopts the http protocol, which is forwarded to the http module for processing;

[0070] 4. The server-side application performs business processing.

[0071] The technology of the invention realizes that multiple protocols are supported in one port, and the application program can send information of different protocols to this port only if it knows the information of one port of the server, and the server judges the format of the information and distinguishes the protocols used. Do forwarding to a different function raw socket port for processing.

[0072] The advantages of the present invention are:

[0073] 1. Provide network services of different network protocols (TCP, TLS, HTTP) on the same network port, realizing the multiplexing of network ports.

[0074] 2. It is implemented in proxy mode, and the received packets are parsed through the external port network proxy, and then forwarded to the internal ports on different protocols. This implementation method simplifies the implementation and is more conducive to the expansion of the old system.

[0075] The embodiment of the present invention also provides a network protocol internal proxy forwarding device, including:
