Actionscript 3 如何在flash player中使用Google Drive API？

我想在我的flash组件中使用google drive api

我有一个访问密钥，但我不能使用谷歌驱动器api。 我想把文件插入谷歌硬盘

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');

我得到以下错误

[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."]

我的服务器crossdomain.xml

<cross-domain-policy>
  <allow-access-from domain="*"/>
  <site-control permitted-cross-domain-policies="all"/>
  <allow-http-request-headers-from domain="*"/>
</cross-domain-policy>

有人能告诉我一个解决办法吗

<cross-domain-policy>
  <allow-access-from domain="*"/>
  <site-control permitted-cross-domain-policies="all"/>
  <allow-http-request-headers-from domain="*"/>
</cross-domain-policy>
