从每首歌曲获取HTTP MP3流 [英] Get HTTP MP3 stream from every song
问题描述
我需要从SoundCloud MP3文件中获取直接URL.
我通常使用以下方法: 解析轨道URL以获取轨道ID，例如配合使用 https://soundcloud.com/linkin_park/burn-it-down >
http://api.soundcloud.com/resolve.json?url=http://soundcloud.com/your/link/to/the/track&client_id=client_id
然后使用
http://api.sndcdn.com/i1/tracks/track_id_here/streams?client_id = client_id
在大多数情况下，将返回我需要的URL"http_128_mp3_url"，该URL直接链接到歌曲的MP3.
但是在某些情况下，例如当您使用 https://soundcloud.com/dada-life/dada- life-september-2014-mix ，仅返回rtmp或hls流，我无法使用PHP或JavaScript将其转换为文件.
在 http://sounddrain.com/上可以看到，有一种方法可以获取MP3的链接在这种情况下也是文件.
Sounddrain给了我这个URL:
有人知道如何获取以下网址吗?
我认为这与您传递到API请求中的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，我看不到http链接:
响应:
{

更多信息可以在此提交和此问题.我不知道常规的client_id和iPhone client_id之间有什么区别，但是我可以清楚地看到API请求返回的区别.似乎iPhone client_id是SoundCloud iOS客户端用来在应用程序中流式播放曲目的API密钥.
I need to get the direct URL from a SoundCloud MP3 file.
I normally used the following method: Resolve the track URL to get the track id, e.g. using https://soundcloud.com/linkin_park/burn-it-down with
http://api.soundcloud.com/resolve.json?url=http://soundcloud.com/your/link/to/the/track&client_id=client_id
Then go for the stream_urls with
http://api.sndcdn.com/i1/tracks/track_id_here/streams?client_id=client_id
In most cases, the "http_128_mp3_url", the URL I need, is returned, which links directly to the MP3 of the song.
But in some cases, e.g. when you use https://soundcloud.com/dada-life/dada-life-september-2014-mix, only the rtmp or hls stream is returned, which I cannot convert to a file with PHP or JavaScript.
As seen on http://sounddrain.com/, there is a way to get the link for the MP3 file in this case too.
Sounddrain gives me this URL:
Has someone an idea how to get the following URL?
I think this specifically has to do with the type of client_id you pass into the API request.
HTTP GET: http://api.soundcloud.com/i1/tracks/167132129/streams?client_id=[CLIENT_ID]
Using a standard application client_id, I don't see the http link:

However, using the youtube-dl iPhone client_id, the http url is returned:

More information can be found in this commit and this issue on the youtube-dl page. I don't know exactly what the difference is between a regular client_id and an iPhone client_id, but I can clearly see the difference in what is returned by the API request. It would appear that the iPhone client_id is the API key used by the SoundCloud iOS client to stream tracks in the app.
