socket作业

作业一：
整理博客
预习基于udp的套接字

作业二：
基于tcp的套接字实现远程执行命令的操作

import socket
import subprocess
phone=socket.socket(socket.AF_INET,socket.SOCK_STREAM) #买手机
phone.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
phone.bind(('127.0.0.1',8081)) #绑定手机卡

phone.listen(5) #开机

while True:
    conn,addr=phone.accept() #等待电话链接
    print('电话线路是',conn)
    print('客户端手机号是',addr)
    while True: #通信循环
        try:
            data=conn.recv(1024) #收消息 ?1024
            print('客户端发来的消息是',data)
            res=subprocess.Popen(data.decode("utf8"),shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
            correct_info=res.stdout.read()
            error_info=res.stderr.read()
            if not error_info:

        except Exception:

    conn.close()

phone.close()
