python最新QQ音乐sign参数加密分析
2023-12-22 06:29:41
?
1. 前言
最近正在学习python爬虫，刚好拿QQ音乐练手。想要看懂文章前建议学习js逆向知识，其中断点和webpack包知识是基本
2. 接口抓包
通过接口分析发现，请求接口中都带有加密参数sign值
??
接着全局搜索sign值，发现只有vendor.chunk.ef9ae512d819f8adc326.js才有sign参数调用
通过搜索和上下文分析找到获取sign值的位置
断点查看，i值出来的sign值正好匹配上。
从断点看出执行o(t.data)，而o = n(350).default是webpack的调用形式，n是加载器（这里就涉及到webpack知识）
3. 整理webpack包代码
为了方便，也不用做去掉无用代码，直接拿来require使用，新建ventor.js把vendor.chunk.ef9ae512d819f8adc326.js内容放进去，新建main.js把加载器复制进去，然后require，接着通过前面的断点，获取到的t.data，执行
// 补环境
var main
require('./ventor')

function t(t) {
for (var r, n, d = t[0], f = t[1], i = t[2], l = 0, b = []; l < d.length; l++)

Object.prototype.hasOwnProperty.call(f, r) && (e[r] = f[r]);

console.log(o(data))最终执行结果发现执行效果对了，但是值没匹配上
4. 补window环境
继续断点，然后发现是有使用到window环境
不知道对不对，先把真实的window、location、navigator补齐
window = global;
location = {
"ancestorOrigins": {},
"href": "https://y.qq.com/n/ryqq/search?w=%E5%91%A8%E6%9D%B0%E4%BC%A6",
"origin": "https://y.qq.com",
"protocol": "https:",
"host": "y.qq.com",
"hostname": "y.qq.com",
"port": "",
"pathname": "/n/ryqq/search",
"search": "?w=%E5%91%A8%E6%9D%B0%E4%BC%A6",
"hash": ""
}
navigator = {
appCodeName: "Mozilla",
appName: "Netscape",
appVersion: "5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"
}
重新执行，结果匹配上了
5. JS代码整理
全部main.js代码，ventor.js直接点击跳转下载，后续可能会更新，最好是抓新的
