搜狐网模拟登录案例

需求:通过协议模拟登录搜狐网

网址:https://www.sohu.com/


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
在这里插入图片描述


没有找到调用对象,那么ctrl+F 全局搜索password
在这里插入图片描述

在这里插入图片描述
大致看了一下,找到passport.js 进行断点
在这里插入图片描述
调试发现,该位置就是password的加密方法
在这里插入图片描述
点击跳转到 utils.md5()方法中,把这一段js复制出来

在这里插入图片描述
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
