基于 Python3 的网易云音乐下载器（支持嵌入专辑封面等 ID3-Tags 信息）

[codezjx]

前阵子开源了个下载器，可以免费下载网易云的付费音乐并嵌入专辑封面，用了一阵子暂时没发现什么问题，特地分享给大家。

简单介绍：

基于 Python3 编写的网易云音乐命令行下载器，自动下载专辑封面，记录歌手名、音乐标题、专辑名等元数据，并写入 ID3 Tags metadata 容器。在 GitHub 上试了几个高星的下载器都没有写入专辑封面，对于强迫症患者简直不能忍，于是一怒之下决定自己写，欢迎各位支持。

当心 dmca.... 猪厂法务部属于跑得快的那种

免费歌曲本来就可以下载，付费歌曲买个会员也不贵，你喜欢的项目到最后赚不到钱，最后受害的不还是自己么。

[codezjx]

@KiseXu 网易云上面很多音乐都下架了，开个会员一点意义都没有，我之前就是开了一阵子的会员到头来还是得去虾米或者 QQ 音乐下。

@sobigfish GitHub 上有好多个下载器，都还坚挺着，淡定淡定。。。

[sobigfish]

@codezjx #4 我很淡定 只是提个醒，免得 repo list 里多个删不掉的被屏蔽的 repo （搜了下貌似是有不少，说明没以前那么夸张了？）

应该添加代理或者间隔时间的。。。。

@inmyfree 我之前是网络不稳定的时候会出现这个，偶发的，你隔一会再试试看，我这边是可以下载的。

[codezjx]

@sobigfish 猪厂的法务估计已经放弃抵抗了，网上的破解教程实在是太多，防不胜防。他们的程序猿小哥快点把漏洞给填了才是硬道理。

[sunnyzhi]

我最近也在研究如何抓取 MOOV （一个香港的音乐 app ）音乐文件，低码流的 acc 格式用的是 m3u8 的 hls 方式，这个没什么难度很容易搞定。但是无损版本的 acc 文件，不知道解密的细节以及不知如何取得 key。
网易云是否需要反编译 app 才找到相关解密的方法呢？能否大致讲讲工作的流程，路线？

[623902748]

可不可以把歌词也嵌到 ID3-Tags 中？

[codezjx]

@sunnyzhi 网易云的破解烂大街了，github 上随便搜一大堆，我是参考 github 是的这个项目： https://github.com/darknessomi/musicbox
之前看文章是说通过 2 次 AES 对称加密了内容，然后秘钥和加密过程写在 js 里面了，所以很容易被破了。

[codezjx]

@623902748 有相关的 api 可以获取到歌词，http://music.163.com/api/song/lyric?id=123123&lv=1。
讲道理，嵌入歌词也是没问题的，可以上去给我提个 issue，我有空试下。
对了，异步歌词和同步歌词有啥区别？ ID3 里面有这两种。
