Python 的socke编程示例详解编程语言

最近了解python的socket编程，写了个小的例子

客户端代码：

#!/usr/bin/env python 
# -*- coding:utf-8 -*- 
 
import socket 
import logging 
 
 
def client_connect(): 
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0) 
    s.connect(('127.0.0.1', 8080)) 
    import time 
 
    time.sleep(2) 
    s.send("1") 
    print '1::', s.recv(1024) 
 
    s.close() 
 
 
if __name__ == '__main__': 
    client_connect()

服务器端代码：

#!/usr/bin/env python 
# -*- coding:utf-8 -*- 
 
import socket 
import logging 
 
 
def listen(): 
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0) 
    s.bind(('localhost', 8080)) 
    s.listen(5) 
    while True: 
        connection, address = s.accept() 
        print 'connection:::', connection 
        print 'address:::', address 
 
        try: 
            connection.settimeout(5) 
            buf = connection.recv(1024) 
            print 'buf::', buf 
            if buf == '1': 
                connection.send("welcome to server!") 
            else: 
                connection.send("please go out.") 
        except socket.timeout: 
            print 'time out' 
 
        connection.close() 
 
 
if __name__ == '__main__': 
    print 'begin...' 
    listen() 
    print 'end...'
