前几天想抓个歌单来着，调下之前的api发现获取歌单音乐列表失败了，于是跟进去分析，仅供参考学习
Ps. 刚分析完，好像现在又变了，有空再写
歌单url地址 https://music.163.com/#/playlist?id=2871000053
主要html分析
主要是对id为song-list-pre-data进行解密分析
主要js分析
- pt_playlist_index.js 歌单列表脚本
- core.js
直接定位关键字decodeURIComponent，备注：这是经过若干繁琐的分析定位的，细节又臭又长，略了
var C4G = cG5L.value || cG5L.defaultValue;
if (gs && bqD4H) {
if (type == 13) {
C4G = C4G.slice(2)
}
C4G = decodeURIComponent(coj6d(C4G, typeof window[l4p.rv0x()] + gs + bqD4H))
}
C4G = JSON.parse(C4G);
直接打下断点，发现最开始的C4G获取的是那串加密数据，然后经过解密，经过若干计算，返回urlencode的数据
// 省略部分数据

搞定，细节就不去折腾了，有空再说，另本文仅参考学习
