Python tcp socket编程详解

初学脚本语言Python，测试可用的tcp通讯程序：

服务器：

#!/usr/bin/env python 
# -*- coding: utf-8 -*- 
 
import socket 
import threading 
import time 
 
def tcplink(sock, addr): 
 print('Accept new connection from %s:%s...' % addr); 
 sock.send(b'Welcome!!!'); 
 while True: 
 data = sock.recv(1024); 
 time.sleep(1); 
 if not data or data.decode('utf-8') == 'exit': 
 break; 
 sock.send(b'Hello, %s!' % data); 
 sock.close(); 
 print('Connection from %s:%s closed.' % addr); 
 
 
if __name__ == "__main__": 
 
 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM); 
 
 s.bind(('127.0.0.1', 9090)); 
 s.listen(8); #监听8个客户端； 
 print('waiting for connection...'); 
 
 while True: 
 sock, addr = s.accept(); 
 t = threading.Thread(target=tcplink, args=(sock,addr)); 
 t.start(); 

客户端：

#!/usr/bin/env python 
# -*- coding: utf-8 -*- 
 
import socket 
 
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM); 
s.connect(('127.0.0.1', 9090)); 
print(s.recv(1024).decode('utf-8')); 
for data in [b'lk', b'aa', b'bb']: 
 s.send(data); 
 print(s.recv(1024).decode('utf-8')); 
s.send(b'exit'); 
s.close();
