某联webpack解析(js逆向)

仅供学习交流,不得用于违法犯罪。
相当于就是说,基本的webpack格式就是一个自执行函数,函数体中,执行传递进来的参数,这个参数可以是数组也可以是字典。
现在我们直接开始进入主题,开始抓包找到数据返回的位置观察是否存在加密参数或者是一些动态cookies之类的。
我们可以发现并不存在这些内容。
只存在一个加密的参数sign,搜索发现数目太多了,直接开始xhr断点调试。找到位置
找到这个加密的位置,我们先来看一下这个m函数的作用是什么,开始调试,该函数毫无用处。直接写r就行。
找到s的加密函数
?
执行完第一步我们会发现这个函数的主要作用是拼接e,所以我们可以不需要这步拼接的过程,直接传递即可
那么现在我们继续找这个加密参数中不应该出现的内容。找到这个i
直接断点调试,进入其中观察内容。
进入到这个函数里面,我们观察他的结构=,这个就是一个webpack,
所以你现在需要全部赋值下来,然后讲缺少的部分补全。
在外层赋值一个全局变量接收这个值。
开始补环境
修改成字典然后,开始向里面加内容
直接按照错误开始找这些函数补一下环境就可以了。只要缺什么补什么
