Python学习之路：通过socket实现处理多个连接

-----客户端

 1 #客户端
 2 import socket
 3 
 4 client = socket.socket()#相当于声明socket类型，同时生成socket连接对象
 5 client.connect(('localhost',6969))
 6 
 7 while True:
 8     msg = input(">>:").strip()
 9     #client.send(b"Hello World!")
10     client.send(msg.encode("UTF-8"))
11     data = client.recv(1024)
12     #print("recv:",data)
13     print("recv:",data.decode())
14 
15 client.close()

------服务端

 1 #服务器端
 2 import socket
 3 
 4 server = socket.socket()
 5 server.bind(("localhost",6969))#绑定要监听的端口
 6 server.listen()#监听
 7 
 8 print("我要开始等电话了")
 9 
10 while True:
11     conn,addr = server.accept()#等电话打进来
12     print(conn,addr)
13 
14     print("电话来了")
15     while True:
16         data = conn.recv(1024)
17         print("recv:",data)
18         if not data:
19             print("client has lost...")
20             break
21         conn.send(data.upper())
22 
23 server.close()
