建立一个SocketServer,首先要创建一个请求处理类,这个类要继承BaseRequestHandler,还要重写父类里handle()方法,handle()方法在父类中为空的
然后实例化TCPServer,并且传递server ip和创建的请求处理类给这个TCPServer
服务器端
# -*-coding:utf-8-*- __author__ = "MuT6 Sch01aR" import socketserver,socket class MyTCPHandler(socketserver.BaseRequestHandler): #创建请求处理类,继承BaseRequestHandler def handle(self): #重写父类里handle()方法 while True: try: self.data = self.request.recv(1024).strip() print(\'来自\',self.client_address[0]) print(self.data) self.request.send(self.data) except socket.error: print(\'客户端断开连接\') break if __name__ == "__main__": HOST, PORT = "localhost", 9999 server = socketserver.TCPServer((HOST, PORT), MyTCPHandler) #实例化TCPServer # server = socketserver.UDPServer((HOST, PORT), MyTCPHandler) #实例化UDPServer server.serve_forever() #处理多个请求,一直执行 # servser.handle_request() #只处理一个请求
客户端
# -*- coding:utf-8 -*- __author__ = "MuT6 Sch01aR" import socket s = socket.socket() s.connect((\'localhost\', 9999)) while True: cmd = input(\'>>>:\').strip() if len(cmd) == 0:continue s.send(cmd.encode(\'utf-8\')) print(s.recv(1024)) s.close()
运行结果
但是还是不能实现多个连接进行socket通信
socketserver多并发
服务器端
# -*-coding:utf-8-*- __author__ = "MuT6 Sch01aR" import socketserver,socket class MyTCPHandler(socketserver.BaseRequestHandler): def handle(self): while True: try: self.data = self.request.recv(1024).strip() print(\'来自\',self.client_address[0]) print(self.data) self.request.send(self.data) except socket.error: print(\'客户端断开连接\') break if __name__ == "__main__": HOST, PORT = "localhost", 9999 server = socketserver.ThreadingTCPServer((HOST, PORT), MyTCPHandler) #通过多线程实现TCPServer多并发 #server = socketserver.ForkingTCPServer((HOST, PORT), MyTCPHandler) #通过多进程实现TCPServer多并发 #server = socketserver.ThreadingUDPServer((HOST, PORT), MyTCPHandler) #通过多线程实现UDPServer多并发 #server = socketserver.ForkingUDPServer((HOST, PORT), MyTCPHandler) #通过多线程实现UDPServer多并发 server.serve_forever()
windows系统还不能用多进程进行socketserver多并发
客户端
# -*- coding:utf-8 -*- __author__ = "MuT6 Sch01aR" import socket s = socket.socket() s.connect((\'localhost\', 9999)) while True: cmd = input(\'>>>:\').strip() if len(cmd) == 0:continue s.send(cmd.encode(\'utf-8\')) print(s.recv(1024)) s.close()
