模拟浏览器服务器代码

模拟服务器代码：

import socket

sok = socket.socket()
sok.bind(('127.0.0.1',7788))
sok.listen(3)
while True:
    print("李凤娟服务器已启动...........")
    conn,addr = sok.accept()
    print("conn:", conn) # conn: <socket.socket fd=312, family=2, type=1, proto=0, laddr=('127.0.0.1', 7788), raddr=('127.0.0.1', 56911)>
    print("addr:", addr) # addr: ('127.0.0.1', 56911)
    data = conn.recv(1024)
    print("服务器接收到的数据：", data) # 服务器接收到的数据： b'GET / HTTP/1.1\r\nHost: 127.0.0.1:7788\r\nConnection: keep-alive\r\nsec-ch-ua: "Not/A)Brand";v="99", "Google Chrome";v="115", "Chromium";v="115"\r\nsec-ch-ua-mobile: ?0\r\nsec-ch-ua-platform: "Windows"\r\nUpgrade-Insecure-Requests: 1\r\nUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36\r\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7\r\nSec-Fetch-Site: none\r\nSec-Fetch-Mode: navigate\r\nSec-Fetch-User: ?1\r\nSec-Fetch-Dest: document\r\nAccept-Encoding: gzip, deflate, br\r\nAccept-Language: zh-CN,zh;q=0.9\r\n\r\n'
    conn.send(b"HTTP/1.1 200 ok\r\n\r\n<h2>abc</h2>")
