Actionscript 3 Youtube Api沙盒冲突

最近，我注意到一条沙箱违规消息，如下所示。这似乎是youtube.com和s.ytimg.com之间的跨域策略问题。我不确定，但如果有任何帮助，我们将不胜感激

*安全沙盒冲突*

SecurityDomain'xhttps://www.youtube.com/apiplayer?version=3”“我试过了 访问不兼容的上下文 'xhttps://s.ytimg.com/yts/swfbin/player-vflq_SRd4/apiplayer3.swf"

SecurityError:错误#2121:安全沙盒冲突： Loader.content：xhttps://www.youtube.com/apiplayer?version=3 不能 通道 xhttps://s.ytimg.com/yts/swfbin/player-vflq_SRd4/apiplayer3.swf. 这 可以通过调用Security.allowDomain来解决此问题

at flash.display:：Loader/get content（）at com.google.youtube.application:：SwfProxy/onRequestParameters（）位于 flash.events:：EventDispatcher/dispatchEventFunction（）位于 flash.events:：EventDispatcher/dispatchEvent（）位于 com.google.youtube.model:：YouTubeEnvironment（）位于 com.google.youtube.application:：VideoApplication/createYouTubeEnvironment（） 在 com.google.youtube.application:：VideoApplication/onLoaderInfoInit（）

我总是被Flash Builder和Flashdevelop控制台中的信息信息淹没，这些信息看起来就像是您错误的第一行。这是由YouTube糟糕的crossdomain.xml和Flash不合理的跨域安全性造成的，但并不影响编译。最近，它们变成了停止编译的错误消息。它们与您的相同，也显示了错误跟踪线。我没有更改任何相关代码或更改Flash版本/设置，因此我怀疑这是YouTube更改的内容。我注意到我的错误在我认为应该是http的时候提到了https。谢谢你好心的先生。我想确定的是，我没有错过一些新的东西或某种类型的更新。几天前开始的。
