切换的时候抓包：
看一下请求参数：
看看返回的数据：
可以观察一些看到返回的数据的基本都是0-9A-F
经过了： 明文 -> 加密 -> 字节 -> 十六进制的处理
下面来找加密入口
全局搜索，搜URL：
打上断点：
注意看下面这行，e参数传进去，经过一些列运算，e重新赋值了，所以传进去的e 和最终计算后的e不是同一个值，
可以看到e的值是：
当鼠标在上面划来划去，选中下面，下图变色了，变成黄色了，意味着e被运行了。
如果不小心已经被运行了，我们需要放开所有断点，重新来。
再看e，不一样了：
摘出来看看：
1 == (e = "{" == e[0] ? JSON.parse(e) : JSON.parse(webInstace.shell(e))).Status || 200 == e.Code ? r(e.Data) : 200 == e.code ? r(e.data) : o(e.Msg)首先，判断 e[0] 即e第一个字符串是不是等于 "{" ，相等，就执行JSON.parse(e)。
前面已经知道了e是加密的一串字符串，"{" == e[0] 所以这个判断就不成立。
所以直接会走到后面： JSON.parse(webInstace.shell(e))
这里就能暴露了加密的入口：
整个执行流程如下：
e是个密文 -> webInstace.shell() -> 计算后的数据 -> JSON.parse()
从而可以得出：webInstace.shell() 是一个解密计算。
webInstace.shell() 计算后判断状态是否等于一些值，随后就把数据放到了网页上。
看一下 webInstace.shell() 内容：
在console输入： webInstace.shell，然后点击它
进入 webInstace.shell() 函数，然后设置断点：
看到下面的数据没有解密：
看到下面有大量的 0x2246
可以看到这个函数有大量被使用。所以 0x2246 这个函数就用还原字符串的函数。
找到最上边：
粗略分析一下：atob 就是Python 中的 base64
也就是：
分析这句话： this[_0x2246('0x257', 'nArV')] = function(_0xa0c834)
在console看看：（之后都是这种操作，不再赘述）
this['shell'] = function(_0xa0c834) 也就是 this.shell = function(_0xa0c834)
所以知道了为啥用的时候直接用 webInstace.shell() 就可以了。
并且最后面可以看到：
再来看 webDES 是什么：

}可以看到声明的对象：var _0x4da59e 和 var _0x9843d3 ，但是并没有参数任何的解密操作。
后面有一个 _0x51eedc[_0x2246('0x258', '@1Ws') ，而 _0x2246 前面已经介绍过，是用来还原字符串的。
运行一下：
其他 0x2246 函数都可以通过这样的方式运行出来：
再还原一下这个：
继续像下面一样，扣出来：
if 语句还原成如下所示：
其实就是废代码，没什么卵用，可以直接删除掉：
再来看下面这段：
可以还原成：
再看上面的，对应上：
做了运算后，就是：
进一步处理：
而 0x0 其实就是 0
看看 while 里面的是什么：
放到console里跑：
所以就是：
再来看switch，这个非常重要，switch 其实就是 开始循环数组的内容：先是数组第0个也就是7，第一个也就是1，第三个也就是8，，，，直到最后一个循环完。
所以第一个运行的代码就是 case 7 ，也就是下面的内容先运行。
再运行 case 1 ，也就是下面的内容：
可以看出，上面的switch case 语句其实就是 控制流（也叫平坦流），是用来混淆执行顺序的，我们可以用数组来还原数组的正确顺序。
还原成正确的顺序：
再把各个看不明白的东西还原：
放到console里看：
navigator对象在window
正常浏览器都有navigator，而且不可能解密的时候，第一句话就返回，所以下面两句话可以直接干掉：
下面这些语句，其实就是把常规的运算符进行了封装：
ob混淆的代码，可以改为（已经把一些看不太懂的变量改成 a、b、mi等）：
var CryptoJS = require("crypto-js")
var _0x9843d3 = function(a, b, c) {
if (0 == b)
return a['substr'](c);
var _0x48914b;
_0x48914b = '' + a['substr'](0x0, b);
return _0x48914b += a['substr'](b+ c);
};
function fn(mi) {
var a = parseInt(mi[mi['length']- 1], 16)+ 9
, b = parseInt(mi[a], 16);
mi = _0x9843d3(mi, a, 1);
a = mi['substr'] (b, 8);
mi = _0x9843d3(mi, b, 8);
b = CryptoJS['enc']['Utf8']['parse'](a);
a = CryptoJS['enc']['Utf8']['parse'](a);
a = CryptoJS['DES']['decrypt']({
'ciphertext': CryptoJS['enc']['Hex']['parse'](mi)
}, b, {
'iv': a,
'mode': CryptoJS['mode']['ECB'],
'padding': CryptoJS['pad']['Pkcs7']

return a['substring'](0, a['lastIndexOf']('}')+ 1);
