This article mainly introduces multi-client access in python multi-threaded socket programming in detail, which has certain reference value. Interested friends can refer to
Implementing socket communication in Python The server side is relatively complex, but the client side is very simple, so the client side is basically implemented using the sockct module, while the service side has many modules that can be used, as follows:
1. Client
#!/usr/bin/env python #coding:utf-8 ''' file:client.py date:9/9/17 3:43 PM author:lockey email:lockey@123.com desc:socket编程客户端,python3.6.2 ''' import socket,sys HOST = '192.168.1.6' PORT = 8998 ADDR =(HOST,PORT) BUFSIZE = 1024 sock = socket.socket() try: sock.connect(ADDR) print('have connected with server') while True: data = input('lockey# ') if len(data)>0: print('send:',data) sock.sendall(data.encode('utf-8')) #不要用send() recv_data = sock.recv(BUFSIZE) print('receive:',recv_data.decode('utf-8')) else: sock.close() break except Exception: print('error') sock.close() sys.exit()
2. SocketServer module
#!/usr/bin/env python #coding:utf-8 ''' file:client.py date:9/9/17 3:43 PM author:lockey email:lockey@123.com desc:socket编程服务器端,python3.6.2 ''' from socketserver import BaseRequestHandler,ThreadingTCPServer import threading BUF_SIZE=1024 class Handler(BaseRequestHandler): def handle(self): address,pid = self.client_address print('%s connected!'%address) while True: data = self.request.recv(BUF_SIZE) if len(data)>0: print('receive=',data.decode('utf-8')) cur_thread = threading.current_thread() #response = '{}:{}'.format(cur_thread.ident,data) self.request.sendall('response'.encode('utf-8')) print('send:','response') else: print('close') break if __name__ == '__main__': HOST = '192.168.1.6' PORT = 8998 ADDR = (HOST,PORT) server = ThreadingTCPServer(ADDR,Handler) #参数为监听地址和已建立连接的处理类 print('listening') server.serve_forever() #监听,建立好TCP连接后,为该连接创建新的socket和线程,并由处理类中的handle方法处理 print(server)
