爬虫逆向实战（十七）--某某丁简历登录

一、数据接口分析

主页地址：某某丁简历

1、抓包

通过抓包可以发现数据接口是submit
在这里插入图片描述

2、判断是否有加密参数

请求参数是否加密？
通过查看“载荷”模块可以发现有一个enPassword加密参数
请求头是否加密？
通过查看请求头可以发现有一个Token的加密参数
响应是否加密？
无
cookie是否加密？
无

二、加密位置定位

1、enPassword

（1）看启动器

查看启动器发现调用堆栈中有一个success，点进去查看
在这里插入图片描述
点进去后发现，此处就是加密位置，同时还可以看到加密是在对public_key接口请求的回调函数中进行的，加密时需要用到该接口响应的数据。

2、Token

（1）搜索关键字

通过搜索关键字token:可以找到给请求头中放token的位置，同时可以发现网站是从cookie中取的token
在这里插入图片描述
讲cookie清除，重新刷新页面，可以发现在请求html页面时，服务器返回的响应头中会设置cookie中token的值

三、扣js代码

先请求public_key接口获取到数据，然后将定位到的加密位置的代码扣出，缺啥补啥。

四、思路

先请求html页面，获取到token值，将token设置到请求头中，再请求public_key接口获取到数据，使用数据将密码进行加密，发送登录请求。
