• 写一个两个人的聊天系统，可以实现双向聊天功能。
  如果发送的是普通的文字就直接打印，如果发送的文字是’拜拜’就关闭连接，
  如果是一个网络地址就获取数据(保存到文本文件中)，如果是图片地址就下载图片到本地

server代码

import re
import socket
from requests import request
#1.创建服务器
server = socket.socket()

# 绑定地址
server.bind(('10.7.181.86',8060))

# 3.监听
server.listen(50)

# 保持服务器不关闭
while True:
    conversation, addr = server.accept()

    # 让客户端和服务器一直处于连接状态
    while True:
        # 发送消息
        message = input('>>>')
        conversation.send(message.encode())
        if message == '拜拜':
            break

        if re.fullmatch(r'./S+./S+',message):
            with open(message, 'rb') as f:
                data = f.read()
            conversation.send(data)


        # 接收消息
        message_data = conversation.recv(1024)
        print(message_data.decode(encoding='utf-8'))
        if message_data.decode(encoding='utf-8') == '拜拜':
