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();
