--version 1.0 只完成server/client 之间的通信。

1、server端的代码：

#!/usr/bin/python#!coding:utf-8from socket import *import os,sysif __name__=="__main__":    #定义套接字    hostIp='127.0.0.1'    port=2048    sock=socket(AF_INET,SOCK_STREAM)    sock.bind((hostIp,port))    sock.listen(5)    print '[info]    开始监听{0}:{1}'.format(hostIp,port)    while True:        #接受一个客户端的连接        conn,addr = sock.accept()        print '[info]    has recived a client from {0}'.format(addr)        #与客户端进行交互，直到客户端退出        while True:            #接收客户端发来的信息，一次最多收1024字节            recivedData=conn.recv(1024)            #由于客户端在断开时会发送一个空串，所以我们用这个上来测试连接是否断开            if not recivedData : print '[wan]    客户端已经断开连接...'; break;            print '[info]    this is a infomation from client --> {0}'.format(recivedData.decode())            #发送信息到客户端            conn.send('this inforamtion from server --> {0}'.format(recivedData.decode()).encode())        conn.close()

2、client端的代码：

#!/usr/bin/python#!coding:utf-8from socket import *import os,sysif __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()
