    简单难度：如果不想花时间在加解密上的话可以用模拟浏览器方式从生成的 DOM 里爬解密后的数据。
    困难难度：把用于加解密的 js 代码从混淆后的 js 文件中整理出来，然后用 Python 跑或者用 nodejs 以接口方式提供调用。
    地狱难度：破解混淆后的 js 文件中的加密算法，直接在 Python 中自己解密。

    你那个是 nodejs 没初始化,找不到模块
    用 buffer 解码下就可以了
    function atob(a) {
    var b = new Buffer.from(String(a), 'base64')
    return b.toString();
    }
    function btoa(a) {
    var b = new Buffer.from(String(a));
    return b.toString('base64');
    }

    console.log(btoa('v2ex.com'));
    console.log(atob('djJleC5jb20='));

    控制台调试相关参数 对比 nodejs 输出有哪些异常
    I = s(t),
    L = 0,
    D = e.length,
    执行这一行时
    浏览器 D 值 26712; nodejs D 值为 25310
    就可以知道 Buffer 转码异常
    function atob(a) {
    var b, c, e, d, f, g = [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, 62, -1, -1, -1, 63, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, -1, -1, -1, -1, -1, -1, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, -1, -1, -1, -1, -1, -1, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, -1, -1, -1, -1, -1];
    d = a.length;
    e = 0;
    for (f = ""; e < d;) {
    do b = g[a.charCodeAt(e++) & 255]; while (e < d && -1 == b);
    if (-1 == b) break;
    do c = g[a.charCodeAt(e++) & 255]; while (e < d && -1 == c);
    if (-1 == c) break;
    f += String.fromCharCode(b << 2 | (c & 48) >> 4);
    do {
    b = a.charCodeAt(e++) & 255;
    if (61 == b) return f;
    b = g[b]
    } while (e < d && -1 == b);

    if (-1 == c) break;
    f += String.fromCharCode((b & 3) << 6 | c)
    }
    return f
    }


    用这个函数替换 Buffer 就可以了
