2. JavaScript部分

网易云音乐.js

var CryptoJS = require('crypto-js') // 导入加密库
var {setMaxDigits, RSAKeyPair, encryptedString} = require('./rsa.js')

// 加密函数
function fun(d, e, f, g) {
    var h = {}
      , i = a(16);
    return h.encText = b(d, g),
    h.encText = b(h.encText, i),
    h.encSecKey = c(i, e, f),
    h
}

// 随机值
function a(a) {
    var d, e, b = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789", c = "";
    for (d = 0; a > d; d += 1)
        e = Math.random() * b.length,
        e = Math.floor(e),
        c += b.charAt(e);
    return c
}

// params的生成 AES加密
function b(a, b) {
    var c = CryptoJS.enc.Utf8.parse(b)
      , d = CryptoJS.enc.Utf8.parse("0102030405060708")
      , e = CryptoJS.enc.Utf8.parse(a)
      , f = CryptoJS.AES.encrypt(e, c, {
        iv: d,
        mode: CryptoJS.mode.CBC
    });
    return f.toString()
}

function c(a, b, c) {
    var d, e;
    return setMaxDigits(131),
    d = new RSAKeyPair(b,"",c),
    e = encryptedString(d, a)
}


function main() {
    var d = '{"ids":"[2144714918]","level":"standard","encodeType":"aac","csrf_token":""}'
    var e = '010001'
    var f = '00e0b509f6259df8642dbc35662901477df22677ec152b5ff68ace615bb7b725152b3ab17a876aea8a5aa76d2e417629ec4ee341f56135fccf695280104e0312ecbda92557c93870114af6c9d05c4f7f0c3685b7a46bee255932575cce10b424d813cfe4875d3e82047b97ddef52741d546b8e289dc6935b3ece0462db0a22b8e7'
    var g = '0CoJUm6Qyw8W8jud'

    var bKL9C = fun(d, e, f, g);
    return bKL9C
}

说明：

1. 在Terminal控制台安装Crypto加密库，执行npm install crypto-js命令，如需更换npm镜像可参考 js逆向部分 的更换npm为国内镜像随笔文章。
2. 网易云音乐.js 中的 rsa.js文件需要根据RSA第三方库生成，生成方法如下：
   访问网址 https://ohdave.com/rsa/ 将图中的内容全部粘贴到rsa.js文件中，如图
