python Socket编程（二）----SocketServer

SocketServer是python网络编程的一个高级模块，封装了一些底层的基本方法，用SocketServer改写上一篇中的例子,服务端的程序如下：

#!/usr/bin/env python

from SocketServer import (TCPServer as TCP,StreamRequestHandler as SRH)
from time import ctime


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

class MyRequestHandler(SRH):
    def handle(self):
        print '...connected from:',self.client_address
        self.wfile.write('[%s] %s' %(ctime(),self.rfile.readline()))


    
tcpServ = TCP(ADDR,MyRequestHandler)
print 'waiting for connection...'
tcpServ.serve_forever()
    

是不是简单很多呢，主要注意类MyRequestHandler是StreamRequestHandler的子类，handle方法是父类的方法，在这里复写并打印。

客户端的程序没什么变化：

from socket import *

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

while True:
    tcpCliSock=socket(AF_INET,SOCK_STREAM)
    tcpCliSock.connect(ADDR)
    data=raw_input('>')
    if not data:
        break
    tcpCliSock.send('%s \r\n' % data)
    data=tcpCliSock.recv(BUFSIZ)
    if not data:
        break
    print data.strip()

tcpCliSock.close()
