前言

现在电商数据采集越来越卷，像shopee这类头号电商平台，web参数已经变成日多更了，对于纯算还原的难度越来越大，一个人的精力是有限的，我们必须寻求一些其他方法获取虾皮的数据。

补环境是一个可行的方案，在补环境之前，我们可以现在浏览器上分析，有些什么参数是虾皮收集的，我们可以在调试之前，先把浏览器框架搭起来，这样方便我们调试也方便我们补环境。

参数分析

显然的是，我们想要的参数是这两组

前者是签名参数，后者是浏览器指纹上报，我们分别走进两个方法分析：

签名参数

新版虾皮协议已经变了，所有的数据都是在n这个大数组中，但是主要的流程还是没有变，我们可以看到上一篇文章的插桩点，进行插桩分析，发现收集了什么参数，同时在日志中也可以协助分析检测点。

浏览器指纹

大概看一下，混淆和签名算法一样，还是找插桩点分析，这里就不再赘述，唯一需要注意的是，浏览器的环境因子是加密的，我们先找到他加密前收集的东西就可以了。
