python爬取网易云音乐歌单音乐

Posted 2020-09-18

在网易云音乐中第一页歌单的url：http://music.163.com/#/discover/playlist/

依次第二页：http://music.163.com/#/discover/playlist/?order=hot&cat=%E5%85%A8%E9%83%A8&limit=35&offset=35

依次第三页：http://music.163.com/#/discover/playlist/?order=hot&cat=%E5%85%A8%E9%83%A8&limit=35&offset=70

然后从歌单的查看框架的源代码：

从图中的源代码可以得到每个歌单的url:eg:http://music.163.com/#/playlist?id=696806036

然后相应的歌单页面中可以得到歌单中每首歌的名字和歌手：

然后歌名歌手，在百度音乐搜索api接口获得songid，api是url = "http://sug.music.baidu.com/info/suggestion"

截图来自：贴吧

然后从获取到的songid从百度音乐免费API接口：http://music.baidu.com/data/music/fmlink，获取songLink进行下载，并且将songLink保存到本地.flac

eg；http://music.baidu.com/data/music/fmlink?rate=320&songIds=242078437&type=flac


下载结果：
