连接客户端到服务器，python

我的服务器和客户端出现问题。我需要客户端将信息发送到服务器，服务器将信息发送回服务器，然后该过程再次重复。我能够让客户端连接到服务器，并在第一轮发送信息，但我似乎不知道如何让服务器在使用conn.shutdown（1）功能关闭发送端后再次侦听客户端。我尝试再次连接到端口，但出现一个错误，显示“传输端点已连接”。有什么建议吗？

尝试使用线程（多线程）-

服务器应用程序

#!/usr/bin/python           # This is server.py file

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.
s.bind((host, port))        # Bind to the port

s.listen(5)                 # Now wait for client connection.


def clientthread(conn):
    conn.send('connected') 
    try:
        while True:        
            data = conn.recv(1024)
            processData(conn,data)
            if not data:
                break
    except Exception as ex:
        print ex
    conn.close()



while True:
   conn, addr = s.accept()    
   print 'Got connection from', addr
   thread.start_new_thread(clientthread ,(conn,))

s.close()

#!/usr/bin/python           # This is client.py file

s.connect((host, port))
print s.recv(1024)
s.close                     # Close the socket when done

   print 'Got connection from', addr
   thread.start_new_thread(clientthread ,(conn,))

s.close()

s.close                     # Close the socket when done

可能重复为什么要在连接完成之前关闭？默认情况下，一个刚刚关闭的套接字将在一段时间内处于“使用中”状态，以防出现散乱的数据包——这是可以解决的，但这是不可取的，除非在极少数情况下它是必不可少的，而你的套接字似乎不是，因为你可以避免过早关闭，不是吗？
