Soundcloud api should support cors as I read in documentation (http://developers.soundcloud.com/docs/api/guide#crossdomain).
But I think this is not the case:
XMLHttpRequest cannot load http://ec-media.soundcloud.com/fxguEjG4ax6B.128.mp3?longurldata... Cannot make any requests from null.
What am I doing wrong? I'm trying to play stream with aurora.js + mp3.js.
回答1:
Unfortunately, at the moment, the CORS headers aren't enabled on the mp3 files that are delivered from the CDN (ec-media subdomain). You'd need to use a proxy if you need to request these files via XHR.
CORS headers are enabled on the JSON data returned from the API, but not the mp3s.
If you are trying to use Web Audio API you could use mediaElementSource and load the mp3 via setting src property of the audio to be used as “media source” as described here.

Supporting CORS isn't an all-or-nothing, the server end chooses to support specific origins (and headers, and methods).
In your case, you appear to be making the call from a local file (origin null), e.g. an HTML document you've loaded via double-clicking from the file system or similar. Apparently they don't allow that.
