服务端:当无端端口有问题时,改个端口
#Socketserver 实现并发 import socketserver class MyServer(socketserver.BaseRequestHandler): def handle(self):#内置handle方法 print('conn is',self.request)#conn print('addr is',self.client_address) while True: try: #收消息 data=self.request.recv(1024) if not data:break print('收到客户端消息是',data) #发消息 self.request.sendall(data.upper()) except Exception as e: print(e) break if __name__ == '__main__':#多线程实现并发,单线程就相当于一个服务员,多线程相当于好几个服务员 s=socketserver.ThreadingTCPServer(('127.0.0.1',8000),MyServer)#myserver相当于通信循环, # threadtcpserver相当于链接循环 s.serve_forever()
客户端:
from socket import * ip_port=('127.0.0.1',8000) back_log=5 buffer_size=1024 tcp_client=socket(AF_INET,SOCK_STREAM)#数据报 tcp_client.connect(ip_port) while True: msg=input('>>').strip() if not msg:continue if msg== 'quit':break tcp_client.send(msg.encode('utf-8')) data=tcp_client.recv(buffer_size) print('收到服务端发来消息是',data.decode('utf-8')) tcp_client.close() #缓冲区为空,输入就会卡住,不往下执行如》》hello,在服务端加上try except 进行异常处理
客户端1与客户端代码相同,
