猿人学js逆向
1 .抓包分析
2 .查看调用堆栈，寻找参数构建位置
3 .来到加密函数这
4.在python中进行模拟
注意:4,5页不能直接访问，要改请求头
5 .总结
url = 第一题 js混淆源码乱码 - 猿人学
声明：本文只作学习研究，禁止用于非法用途，否则后果自负，如有侵权，请告知删除，谢谢！(手动狗头)
1 .抓包分析
来到这个页面，可以知道我们要的数据是这些，对其进行抓包分析
需要破解的参数在负载里
2 .查看调用堆栈，寻找参数构建位置
控制台打印下，果然如此
注意此时window["f"]并没有值，只有当执行完成后才会赋值，很明显oo0O0这个函数要先执行，才能获得值
3 .来到加密函数这
在pycharm中格式化可以看的这个函数，把它给扣下来,会发现缺少window document对象
在浏览器上打印出JSON.stringfy(document)，拿到document对象
而读取js代码可以知道最后是base64进行解码,所以我们可以直接得到window.b的base64的值，将构建的删掉
window = {'a':'isM\x81RQsxrU]xtDhMbZ\x8BJrrd\x83v\x88xP\x84ii\x8Fuyp\x91x]\x85\x94\x90\x97q\x9A\x92z'
}

5 .总结
这个案例主要反爬参数是m,其次是ua和cookie里的sessionid,其中难点在于寻找构建m的函数，以及对m进行模拟构造
难度等级:普通
考察咱的观察能力以及解混淆，适合向我这样的小白练习
