python 网络编程第四版

使用SocketServer 模块来完成服务端编程

1、服务端代码如下：

#!/usr/bin/python

#!coding:utf-8

import SocketServer as socketserver

class ClientHandler(socketserver.BaseRequestHandler):

    def handle(self):

        print '[info]    server has recive a connection :{0}'.format(self.client_address)

        while True:

            reciveData=self.request.recv(1024)

            if not reciveData:print '[info]    server the client has logout';break

            print '[info]    server has reviced this :{0}'.format(reciveData.decode())

            reply='this is the reply information form server -->{0}'.format(reciveData.decode())

            self.request.send(reply.encode())

if __name__=="__main__":

    hostIp='127.0.0.1'

    port=2048

    server=socketserver.ThreadingTCPServer((hostIp,port),ClientHandler)

    server.serve_forever()
    

2、客户端的代码如下：

#!/usr/bin/python

#!coding:utf-8

from socket import *

import os,sys

if __name__ == "__main__":

    #定义套接字

    hostIp='127.0.0.1'

    port=2048

    sock=socket(AF_INET,SOCK_STREAM)

    messages=['hello I am a client']

    messages=messages+sys.argv[1:]

    sock.connect((hostIp,port))

    print '[info]    已经连接到server '

    for message in messages:

        sock.send(message.encode())

        print sock.recv(1024).decode()

    sock.close()
