软件环境：python2.7

1.服务端部分代码

#!/usr/bin/env python
from socket import *
from time import ctime

HOST = ''
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST,PORT)

tcpSerSock = socket(AF_INET,SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)

while True:
    print 'waiting for connection...'
    tcpCliSock,addr=tcpSerSock.accept()
    print '...connected from:',addr

    while True:
        data=tcpCliSock.recv(BUFSIZ)
        if not data:
            break
        tcpCliSock.send('[%s] %s' %(ctime(),data))

    tcpCliSock.close()
tcpSerSock.close()

2.客户端部分代码

#!/usr/bin/env python
from socket import *

HOST='localhost'
PORT=21567
BUFSIZ=1024
ADDR=(HOST,PORT)

tcpCliSock = socket(AF_INET,SOCK_STREAM)
tcpCliSock.connect(ADDR)

while True:
    data = raw_input('> ')
    if not data:
        break
    tcpCliSock.send(data)
    data = tcpCliSock.recv(BUFSIZ)
    if not data:
        break
    print data

tcpCliSock.close()
