python3 socket循环 

 1 import socket
 2 phone=socket.socket(socket.AF_INET,socket.SOCK_STREAM) #买手机
 3 phone.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1) #就是它，在bind前加
 4 phone.bind(('127.0.0.1',8080)) #插入卡
 5 phone.listen(5) #开机
 6 while True: #链接循环
 7     conn,addr=phone.accept()
 8     print('client :',addr)
 9     while True: #通讯循环
10         try:
11             data=conn.recv(1024)
12             if not data:break #针对linux，客户端断开链接的异常处理
13             print('from client msg :%s' %data)
14             conn.send(data.upper())
15         except Exception:
16             break
17     conn.close()
18 phone.close()
