Python socket multithreading and multi-process

The Socketserver internally uses IO multiplexing and "multithreading" and "multi-process" to enable the socket service side to process multiple client requests concurrently. That is, when each client requests a connection to the server, the socket server is creating a "thread" or "process" dedicated to all requests from the current client.

1. Create a inherit from Socketserver. Baserequesthandler class, a method named handle must be defined in the class
2. Start Threadingtcpserver

import socketserverclass MyServer(socketserver.BaseRequestHandler):    def handle(self):        conn = self.request        conn.sendall("我是一个多线程".encode())        Flag = True        while Flag:            data = conn.recv(1024)            if data.decode() == "exit":                Flag = False            conn.sendall(data)if __name__ == "__main__":    server = socketserver.ThreadingTCPServer((‘127.0.0.1‘,8009),MyServer)    server.serve_forever()

客户端直接使用原来的客户端代码即可。

Threadingtcpserver
The Soket server implemented by Threadingtcpserver creates a "thread" for each client that is used to interact with the client.
