今日主题：在Python TCP 协议网络编程《二》的基础上增加了当服务器重启后客户端不挂掉，客户端能够重试连接服务端的功能。
代码实现如下：
server.py文件内容如下
1from socket import socket,SOCK_STREAM,AF_INET #导入模块 2 3def tcp_server(): 4 tcp_server_socket=socket(AF_INET,SOCK_STREAM) #创建TCP服务端套接字对接，UDP是SOCK_DGRAM 5 server_address=('127.0.0.1',9999)#定义本TCP服务端的ip and port 6 tcp_server_socket.bind(server_address) #绑定本机的9999端口 7 tcp_server_socket.listen() #执行监听 8 client_socket,client_info = tcp_server_socket.accept() #接收客户端的socker and info 9 while 1: 10 data=client_socket.recv(1024)#接收客户端发过来的消息 11 datas=data.decode("utf-8") 12 if(len(datas)>1): 13 print("the client say:",datas)#打印客户端发送过来的信息 14 if(datas=="bye"): 15 break 16 server_answer=input('>>>')#从键盘录入信息 17 client_socket.send(server_answer.encode("utf-8")) 18 19if __name__ == '__main__': 20 print("the TCP server is running ...") 21 tcp_server()
client.py文件内容如下
1import time 2 3from socket import socket,SOCK_STREAM,AF_INET #导入模块 4 5 6def connection_socket(): 7 tcp_client_socket = socket(AF_INET, SOCK_STREAM) # 创建TCP客户端套接字对接 8 server_address = ('127.0.0.1', 9999) # 定义本TCP服务端的ip and port 9 try: 10 tcp_client_socket.connect(server_address) # 连接到服务端 11 except: 12 print("connection failed!!!") 13 exit(0) 14 return tcp_client_socket 15 16def tcp_client(): 17 while 1: 18 try: 19 tcp_client_socket=connection_socket() 20 message=input("client>>>") #定义要发送的消息 21 print("the message is:",message) 22 print(tcp_client_socket) 23 tcp_client_socket.send(message.encode("utf-8"))#向服务端发送消息 24 response=tcp_client_socket.recv(1024) 25 print("the server say:",response.decode("utf-8")) 26 except: 27 tcp_client_socket.close()#关闭原有socket连接 28 print("the socket connection is failed, try again to reconnection...") 29 time.sleep(3) 30 31if __name__ == '__main__': 32 print("the TCP client is running ...") 33 tcp_client() 34 print("the message was send")
client console output:
