Communication method based on coroutine mechanism

Abstract

The invention provides a communication method based on a coroutine mechanism. The communication method based on the coroutine mechanism comprises the following steps that firstly, in a main thread circulation process, a socket is monitored; secondly, whether data is input into the socket or not is judged, and the third step is executed if yes; thirdly, the input data is subjected to decoding analysis, whether the input data is request data or response data is judged, the fourth step is executed if the data is request data, and the fifth step is executed if the data is response data; fourthly, a coroutine function is established and used for processing the request data; fifthly, a coroutine function corresponding to the response data is searched for according to the response data, and the coroutine function is switched to process the response data. By means of the communication method based on the coroutine mechanism, the problem of waiting in a blockage mode can be solved, and data access conflict in multi-thread implement can be avoided.

Description

【Technical field】 [0001] The invention belongs to the technical field of computers, and in particular relates to a communication method based on a coroutine mechanism. 【Background technique】 [0002] In the existing computer technology, traditional inter-process or inter-host communication is carried out in the form of Socket. The existing Socket communication includes two modes: blocking mode and non-blocking mode. [0003] Blocking mode, also called serial mode, refers to: implement in a thread or a function, after sending data through the send function, immediately call the recv function to obtain the remote response data in a blocking manner. Moreover, during this process, the thread has been in a waiting state and cannot perform other operations. In this case, multithreading is generally used to implement concurrent operations on the same connection, and shared data uses semaphores to prevent access conflicts. [0004] The non-blocking method, also called the paralle...

However, in this process, the necessary information must be saved through the heap or global memory, and the callback mechanism will lead to the complexity of communication data interaction
