爬虫逆向实战(31)-某花顺行情中心(cookie、补环境)

一、数据接口分析

主页地址:某花顺

1、抓包

通过抓包可以发现数据接口是/page/2/ajax/1/
爬虫逆向实战(31)-某花顺行情中心(cookie、补环境)_第1张图片

2、判断是否有加密参数

  1. 请求参数是否加密?
  2. 请求头是否加密?
    通过查看“标头”可以发现有一个Hexin-V加密参数,但是这个参数的值与cookie中v的值是一致的。

  3. 响应是否加密?
  4. cookie是否加密?
    有一个加密参数v

二、加密位置定位

1、看启动器

查看启动器发现里面包含异步,所以无法正确找到加密位置

2、搜索关键字

通过搜索关键字setcookie,可以找到有一个文件中出现了四处关键字setcookie,所以我们就需要把这四处都打断点。

然后在“应用”模块中的将cookie删除。

再次发包,可以发现代码断在了其中一个位置,并且此处就是设置cookie中的v的,cookie值的生成是调用的上方rt.update方法。

三、扣js代码

因为在扣js代码时发现需要扣很多的东西,而且这个js文件也不是很大,所以,我们可以把整改js文件扣下来,然后一步一步补环境即可。但是这个js文件需要补的环境很多,可以使用对象代理的方式,或者jsdom补环境,也可以代码哪里报错在浏览器中查看需要补哪里。
