SWF为空Facebook Graph API和Actionscript 3库

使用Facebook Adobe ActionScript 3调用Facebook.login（handleLogin，{perms：“user_photos，publish_stream”}）时，Firebug控制台中出现'swf is null' 1.5图形API。不知道是什么问题，但这里是AS3代码：SWF为空Facebook Graph API和Actionscript 3库

package alvincrespo

    import flash.display.MovieClip;

     public var btn_login    :Button; 
     public var txt_status    :TextField; 
     private var APP_ID    :String = ""; //put in the app id here 


     public function Main():void

     Facebook.init(APP_ID, handleInit); 
     }

     else 
     { 
      trace("Main :: handleLogin : Did not Log In!") 
     } 
     } 

     private function handleLogout(success:Boolean):void

     } 

     private function handleLoginClick(evt:MouseEvent):void 
     { 
     trace("Main :: handleLoginClick"); 
     if(Facebook.getSession() == null || Facebook.getSession().accessToken == null) 
     { 
      trace("Main :: handleLoginClick : if"); 
      var fbLoginTimer:Timer = new Timer(1000, 1); 
       fbLoginTimer.addEventListener(TimerEvent.TIMER_COMPLETE, doFBLoginTimerComplete); 
       fbLoginTimer.start(); 
     } 
     else 
     { 
      trace("Main :: handleLoginClick : else"); 
      Facebook.logout(handleLogout); 
     } 
     } 

     private function changeToLoginState():void 
     { 
     trace("Main :: changeToLoginState"); 
     btn_login.label = 'Logout'; 
     txt_status.text = "Logged In";

     trace("Main :: doFBLoginTimerComplete"); 
     evt.target.stop(); 
     Facebook.login(handleLogin, {perms:"user_photos, publish_stream"}); 
     /*Facebook.callJS('redirect', {perms:"user_photos, publish_stream"});*/ 
     } 
    } 
    }

这里是HTML

     <script type="text/javascript"> 
      function redirect() 
      { 
      alert("redirect"); 
      var params = window.location.toString().slice(window.location.toString().indexOf('?')); 
      top.location = 'https://graph.facebook.com/oauth/authorize?client_id=&scope=email,publish_stream,offline_access,read_stream&redirect_uri=http://apps.facebook.com/someapp' + params; 
      } 

      $(document).ready(function(){ 
       swfobject.embedSWF("main.swf", "FlashDiv", "550", "400", "10"); 
      }); 
     </script> 
     </body> 
    </html>

真的不知道是什么问题。任何帮助，将是伟大的！谢谢！

此外，为了安全起见，我在html中留下了客户端id为空的。所以这就是为什么你在这个问题上这样看待它。 – alvincrespo

基本上，您需要设置对象标记的名称和ID，您可以使用SWFObject轻松实现，如下所示。您还需要设置适当的allowcriptaccess属性。
