    思路：

    1.找到传输加密地址，发现加密字段m，，通过全局搜索没有找到m值

    2.通过该地址访问过的js文件排查到request，再通过断电发现m加密地方

    3.找到对应的加密方法，并逐步输出加密方法 找到真正的加密方法

    1. 跳过deg 两种方法

    ​

    ​

     寻找加密地方：

     出现16进制编码 解码网站：https://www.bejson.com/convert/ox2str/

    1. var _0x2268f9 = Date['\x70\x61\x72\x73\x65'](new Date()) + (16798545 + -72936737 + 156138192)
    2.       , _0x57feae = oo0O0(_0x2268f9['\x74\x6f\x53\x74\x72' + '\x69\x6e\x67']()) + window['\x66'];
    3.     const _0x5d83a3 = {};
    4.     _0x5d83a3['\x70\x61\x67\x65'] = window['\x70\x61\x67\x65'],
    5.     _0x5d83a3['\x6d'] = _0x57feae + '\u4e28' + _0x2268f9 / (-1 * 3483 + -9059 + 13542);
    6.     var _0xb89747 = _0x5d83a3;

    1.Date['\x70\x61\x72\x73\x65'](new Date()) + (16798545 + -72936737 + 156138192)

    可以翻译为

    Date['parse'](new Date()) + (16798545 + -72936737 + 156138192)

    获取时间戳并进行了写操作

    2.寻找oo0O0（）方法：通过全局查找找到

     通过nodepad格式化之后得到

    64.     eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));
    65.     return ''
    66. }
    67.  
    68. eval(atob(window['b'])['replace']('mwqqppz', 'mw'));

    eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));
    这一句翻译得到如下

    eval(atob(window['b'])['replace']('mwqqppz', 'mw'));

    在控制台输出atob(window['b']）得到

    2. f = hex_md5(timestamp.toString()) + "|" + timestamp/1000;;
    3. console.log(f)

    爬虫代码：

    3. // document.e = 'fromC';
    4. // window.c = 5;
