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()
