我在这个网站上找到了一个代码，用于 Flash AS3 中的广播流。这是代码：

package {
    import flash.display.Sprite;
    import flash.events.NetStatusEvent;
    import flash.events.SecurityErrorEvent;
    import flash.media.Video;
    import flash.net.NetConnection;
    import flash.net.NetStream;
    import flash.events.Event;

    public class NetConnectionExample extends Sprite {
        private var streamURL:String = "https://myHost:myPort";
        private var connection:NetConnection;
        private var stream:NetStream;

        public function NetConnectionExample() {
            connection = new NetConnection();
            connection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
            connection.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
            connection.connect(null);
        }

        private function netStatusHandler(event:NetStatusEvent):void {
            switch (event.info.code) {
                case "NetConnection.Connect.Success":
                    connectStream();
                    break;
                case "NetStream.Play.StreamNotFound":
                    trace("Stream not found: " + streamURL);
                    break;
            }
        }

        private function securityErrorHandler(event:SecurityErrorEvent):void {
            trace("securityErrorHandler: " + event);
        }

        private function connectStream():void {
            stream = new NetStream(connection);
            stream.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
            stream.client = new CustomClient();
            stream.play(streamURL);
        }
    }
}


class CustomClient {
    public function onMetaData(info:Object):void {
        trace("metadata: duration=" + info.duration + " width=" + info.width + " height=" + info.height + " framerate=" + info.framerate);
    }
    public function onCuePoint(info:Object):void {
        trace("cuepoint: time=" + info.time + " name=" + info.name + " type=" + info.type);
    }
}

但是，当我编译 SWF 时出现此错误：

打开 URL 'https://myHost:myPort' 时出错 SecurityError：错误 #2000：没有活动的安全上下文。

谁能告诉我如何正确地做到这一点？我已经找了两天了，没有结果！！

谢谢

该 url 根本不存在，因为这只是一个示例，但此代码还存在一些其他问题。例如：connection.connect(null)，它不会连接到任何地方，所以netconnection实例根本不会调度netstatus事件，这就是connectStream方法不会被执行的原因。如果您想播放来自直播的流，请使用以下代码：

    var soundOBJ : Sound = new Sound();
    soundOBJ.load(new URLRequest("http://78.159.104.147:80/"));
    soundOBJ.play( );

从这里选择一个流： http ://callear.org/radio-script/demo-flash/xxqpupruq/pickstream.php?id=1377200&title=TechnoBase.FM+-+24h+Techno%2C+Dance%2C+Trance%2C +House+and+More+-+128k+MP3+-+a+SHOUTcast.com+member+station

（只需替换URLRequest的构造函数中的url）
