Python网络编程socket练习（TCP）

服务器端：server.py

# -*- coding: utf-8 -*-
from socket import *
HOST=''
PORT=5000
BUFF_SIZE=1024
ADDR=(HOST,PORT)
serTCP=socket(AF_INET,SOCK_STREAM)
serTCP.bind(ADDR)
serTCP.listen(5)
while True:
    print 'waiting for connect...'
    cliTcp,addr=serTCP.accept()
    print 'successful connect from ',addr
    while True:
        try:
            data=cliTcp.recv(BUFF_SIZE)
            if not data.strip():
                break
            print data 
            cliTcp.send(data)
        except:
            print 'client has exit!'
            break
    cliTcp.close()      
serTCP.close()
raw_input("press enter")

客户端：client.py

# -*- coding: utf-8 -*-
from socket import *
HOST='127.0.0.1'
PORT=5000
BUFF_SIZE=1024
ADDR=(HOST,PORT)
try:
    cliTcp=socket(AF_INET,SOCK_STREAM)
    cliTcp.connect(ADDR)
    print 'successful connect'
except:
    print 'faild linked'
else:
    while True:
        data=raw_input('input your messsage >')
        if not data.strip():  #如果数据为空则关闭连接
            break
        cliTcp.send(data)
        data2=cliTcp.recv(BUFF_SIZE)  #接收来自服务器的数据
        if not data2.strip():
            break
        print data2
cliTcp.close()
