Embodiment Construction
[0026] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0027] see figure 1 , which is a block diagram of the method for realizing the universal encoding and decoding of the SIP protocol proposed by the present invention. It mainly includes the following 4 steps:
[0028] S101. Using regular expressions to describe a single protocol rule;
[0029] S102. Writing the protocol rules into a configuration file;
[0030] S103. Obtain encoding and decoding rules by reading the information in the configuration file, and only need to modify the configuration file when the protocol is extended;
[0031] S104. During the encoding and decoding process of the message, the configuration file is used to describe the field information that needs to be encoded and decoded in the current application, instead of encoding and decoding the entire message.
[0032] In practical application, the protocol codec is implemented first. Since the SIP pro...
