从每首歌曲中获取HTTP MP3流

Question

我需要从SoundCloud MP3文件中获取直接URL.

我通常使用以下方法:解决轨道URL获得道ID,例如使用https://soundcloud.com/linkin_park/burn-it-down与

http://api.soundcloud.com/resolve.json?url=http://soundcloud.com/your/link/to/the/track&client_id=client_id

然后去找stream_urls

http://api.sndcdn.com/i1/tracks/track_id_here/streams?client_id=client_id

在大多数情况下,返回"http_128_mp3_url",即我需要的URL,它直接链接到歌曲的MP3.

但在某些情况下,例如,当您使用https://soundcloud.com/dada-life/dada-life-september-2014-mix时,只返回rtmp或hls流,我无法将其转换为PHP文件或JavaScript的.

如http://sounddrain.com/所示,在这种情况下,有一种方法可以获取MP3文件的链接.

Sounddrain给了我这个URL:

https://ec-media.sndcdn.com/KZ5qiLqZ0OSk.128.mp3?f10880d39085a94a0418a7ef69b03d522cd6dfee9399eeb9a522029c6df9ba3f0cf21c0c0d9baf9fe2d9aa920d344c36db47817ce450103d44677da7d832da82ef7609816e

有人知道如何获得以下网址吗？

Answer 1

我认为这与您传递给API请求的client_id类型有关.

HTTP GET: http://api.soundcloud.com/i1/tracks/167132129/streams?client_id=[CLIENT_ID]

使用标准应用程序client_id,我没有看到http链接:

但是,使用youtube-dl iPhone client_id,将返回http url:

可以在youtube-dl页面上的此提交和此问题中找到更多信息.我不确切知道常规client_id和iPhone client_id之间有什么区别,但我可以清楚地看到API请求返回的内容之间的差异.看起来iPhone client_id是SoundCloud iOS客户端用来在应用程序中流式传输曲目的API密钥.
