最近了解python的socket編程，寫了個小的例子

客戶端代碼：

#!/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()</pre> 


服務器端代碼：

#!/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...'</pre>
