下载某云音乐源文件.mp4格式 首先随便点进一首歌如图所示获取该音乐id然后点击播放键打开F12进行查询XHR 由此可知实际请求网址是
https://music.163.com/weapi/song/enhance/player/url/v1?csrf_token「你的token」url需带上token请求参数有两个params、encSecKey返回json里的id就是该音乐idurl就是本次的目标音乐源文件链接
继续查看启动器查看该路由的调用堆栈信息找到关键位置打断点不会找断点的就每个堆栈全部点进去设置断点然后看哪一个断点结束后url已完成请求的就是关键位置从下图的文件中可知核心文件是core_xxxxx.js可以直接下载到本地方便查看代码。堆栈执行顺序是由下至上 第一步已成功定位到请求路由e7d.data里已经带有(params、encSecKey)后续就直接会请求了那么就继续向上一个堆栈找此函数的参数x7qe7d中的e7d是从哪里传的。
PS请注意一定要找到我们要找的核心url是否由此断点发出的由于一些方法会被反复调用参数值是不一定的。
第二步上图已封装好了e7d且参数params、encSecKey已出现是由window.asrsea产生的继续查找window.asrsea是哪个方法。
window.asrsea(JSON.stringify(i7b), bsc2x([流泪, 强]), bsc2x(RU7N.md), bsc2x([爱心, 女孩, 惊恐, 大笑]));
鼠标悬浮该方法后定位至这里核心就是这个function d接受4个参数分别对应上面的4个值。
其中第一个参数i7b是以下参数构成music_id XXXXXX
song_data {ids: f[{music_id}],level: standard,encodeType: aac,csrf_token: csrf_token
}第三个参数md是一个固定列表第二、第四个参数也是一个短列表值。 核心方法已找到就是function d()剩下的工作就是把d方法里需要涉及到的所有function全部找出来比如function b、c然后继续从b、c里继续递归找方法这一步工作比较繁琐需要耐心。直至自己用js能把function d给跑通就算成功。
通过js里的方法可知里面算法还涉及到了加密需要用到crypto-js库上网百度搜一下直接下载该库的代码保存本地。 以下是js文件代码
