Python中tcpsocket编程的实例详解

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(&＃39;Accept new connection from %s:%s...&＃39; % addr); 
  sock.send(b&＃39;Welcome!!!&＃39;); 
  while True: 
    data = sock.recv(1024); 
    time.sleep(1); 
    if not data or data.decode(&＃39;utf-8&＃39;) == &＃39;exit&＃39;: 
       break; 
    sock.send(b&＃39;Hello, %s!&＃39; % data); 
  sock.close(); 
  print(&＃39;Connection from %s:%s closed.&＃39; % addr); 
 
 
if name == "main": 
 
  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM); 
 
  s.bind((&＃39;127.0.0.1&＃39;, 9090)); 
  s.listen(8); #监听8个客户端； 
  print(&＃39;waiting for connection...&＃39;); 
 
  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((&＃39;127.0.0.1&＃39;, 9090)); 
print(s.recv(1024).decode(&＃39;utf-8&＃39;)); 
for data in [b&＃39;lk&＃39;, b&＃39;aa&＃39;, b&＃39;bb&＃39;]: 
  s.send(data); 
  print(s.recv(1024).decode(&＃39;utf-8&＃39;)); 
s.send(b&＃39;exit&＃39;); 
s.close();
