  1. POOpen stream_url of a Soundcloud Track via Client-Side XHR?
    text
    copied!<p>Since you can call the the Soundcloud API via XHR (because of the CORS headers it sends <a href="http://backstage.soundcloud.com/2010/08/of-cors-we-do/" rel="nofollow noreferrer">http://backstage.soundcloud.com/2010/08/of-cors-we-do/</a>, right?) I was wondering if this was possible with the audio data itself, like a tracks' stream_url for example.</p> <p>When trying to open the stream_url with a XHR (from the Client Side) using the Web Audio API, i get a <em>Origin is not allowed by Access-Control-Allow-Origin.</em> error. Is there a way to load Audio resources via XHttpRequest from Client-Side-Javascript, or is it impossible ( <a href="https://stackoverflow.com/questions/10871882/audio-data-api-and-streaming-a-no-go">https://stackoverflow.com/questions/10871882/audio-data-api-and-streaming-a-no-go</a>) ?</p> <p>Would be great as this would allow some really cool things with the Web Audio API.</p> <p>Thanks!</p> <p><strong>UPDATE</strong></p> <p>The problem might have to do with the 302 redirect you get when calling:</p> <pre><code>http://api.soundcloud.com/tracks/5646378/stream.json?client_id=[client_id] </code></pre> <p>or some other call requesting the actual media file (see comments).</p> <pre><code>HTTP/1.1 302 Moved Temporarily Server: nginx Date: Sun, 24 Jun 2012 09:58:01 GMT Content-Type: application/json; charset=utf-8 Connection: keep-alive Cache-Control: no-cache Location: http://ec-media.soundcloud.com/[...] X-Runtime: 41 Content-Length: 339 Access-Control-Allow-Methods: GET, PUT, POST, DELETE Access-Control-Allow-Headers: Accept, Authorization, Content-Type, Origin Access-Control-Allow-Origin: * X-Cacheable: NO:Cache-Control=no-cache X-Varnish: 2433107209 Age: 0 Via: 1.1 varnish X-Cache: MISS HTTP/1.1 200 OK Accept-Ranges: bytes Cache-Control: max-age=252460800 Content-Type: audio/mpeg Date: Sun, 24 Jun 2012 09:58:01 GMT ETag: "c2241e[...]41bbcf7c0d32f09" Last-Modified: Tue, 28 Sep 2010 17:57:26 GMT Server: ECAcc (fra/D484) x-amz-id-2: oB0XzQcc/[...]+mAr/a x-amz-meta-bitrate: 128 x-amz-meta-duration: 152900 x-amz-meta-job: t405jWkfNvx7 x-amz-request-id: D65[...]E1355 X-Cache: HIT Content-Length: 2445478 </code></pre> <p>The original JSON response has the CORS headers, while the location of the redirect don't.</p>
