解某麦数据请求参数analysis加密

意外发现一个可以查询app下载量得网站，

想筛选一下哪些下载量在1w-10w之间，大概需要5k个.。

感觉应该没啥加密，好把，是我小看了，有个参数是加密得，如图。

analysis

扣js开始，

f12 去资源文件里先去搜一下analysis，竟然没搜到，比较懵逼，咋回事。

多次换了搜索依旧没有。那说明这个字段被拆分了，或者被做了隐藏操作

那就只有拦截请求看看，这里也没有，奇了怪了。

先稳住，一个萝卜一个坑。待我仔细想想。

这个应该还不是最终提交的地方们，继续跟，显先看看是 fetch还是xhr请求

应该是xhr,直接去跟，就当我准备去跟的时候，突然返现一个问题，大量的这种代码。根据以往的经验，跑不掉了，这个就是给某些字符串做了混淆赋值。

不要着急，编程有个规则那就是先定义后使用，直接往上层去找，随便找个字符串去搜索一下，

比如P[Yi]中的Yi,直接定位到了最上面，哈哈，就在这了。写段js把这里面定义的变量都打印出来看一下

写段js 打印一下看看：

好了都出来了，打印结果里搜一下analysis,找到了，p这个字段是他

那就直接找到p在哪被用了，哈哈搜索大法，直接定位到，注意大家别傻乎乎的去搜p会很多，

可以搜"[p]"或者类似的 "p," "=p", "= p","p=","p ="," p ="
