需求：通过协议模拟登录搜狐网
打开登录框，抓包找接口，发现POST接口 https://v4.passport.sohu.com/i/login/116005
userid是输入的邮箱
password是加密后的密码
没有找到调用对象，那么ctrl+F 全局搜索password
大致看了一下，找到passport.js 进行断点
调试发现，该位置就是password的加密方法
点击跳转到 utils.md5()方法中，把这一段js复制出来
复制到html文件中略加修改后用浏览器打开测试，该结果与上面接口数据一致。
下面用代码来完成登录操作，注意修改账号密码
import execjs
import requests
import time
login_url = "https://v4.passport.sohu.com/i/login/116005"
username = "你的账号"
password = '你的密码'
