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/
2、判断是否有加密参数
- 请求参数是否加密？
无 - 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。
- 响应是否加密？
无 - 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。
