actionscript-3 - Flash Player で Google Drive API を使用するには?

Question

Flash コンポーネントで Google ドライブ API を使用したいと考えています。

アクセスキーは取得できますが、Google ドライブ API を使用できません。ファイルをGoogleドライブに挿入したい。

var urlLoader:MultipartURLLoader = new MultipartURLLoader();

urlLoader.addEventListener(Event.COMPLETE, uploadCompleteHandler);
urlLoader.addEventListener(IOErrorEvent.IO_ERROR, uploadIOErrorHandler);
urlLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, uploadSecurityErrorHandler);

urlLoader.requestHeaders.push(new URLRequestHeader("Authorization", authorization));
urlLoader.load('https://www.googleapis.com/upload/drive/v2/files');

次のエラーが表示されます

[SecurityErrorEvent type="securityError" bubbles=false cancelable=false 
eventPhase=2 text="Error #2170: Security sandbox violation:
http://myserver.com/myflash.swf cannot send 
HTTP headers to https://www.googleapis.com/upload/drive/v2/files."]
