上一节我们做了一个客户端调用服务端的例子 这一节我们来换换 服务端调用客户端的例子
配置文件

red5-web.properties
webapp.contextPath=/red5Demo2 webapp.virtualHosts=*, localhost, localhost:8088, 127.0.0.1:8088
接着是Java 服务端
public class Application extends ApplicationAdapter implements IPendingServiceCallback { private IScope appScope; public Application(){ log.info("myDemo created"); System.out.println("myDemo created"); } public boolean appStart(IScope app) { log.info("myDemo appStart"); System.out.println("myDemo appStart"); this.appScope = app; return true; } public boolean appConnect(IConnection conn, Object[] params) { log.info("myDemo appConnect"); System.out.println("connect"); IServiceCapableConnection sc = (IServiceCapableConnection)conn; sc.invoke("clientMethod", new Object[]{"One",1}, this); return super.appConnect(conn, params); } public void appDisconnect(IConnection conn) { log.info("myDemo appDisconnect"); super.appDisconnect(conn); } public void resultReceived(IPendingServiceCall arg0) { System.out.println("来自客户端的返回值 :" + arg0.getResult()); } }
要接收客户端的返回值 需实现 IPendingServiceCallback 接口 重写 resultReceived 方法
sc.invoke("clientMethod", new Object[]{"One",1}, this);
此处调用了客户端的 clientMethod 方法 参数第一个为字符串 第二个为 数值型 其中 this 为实现了 IPendingServiceCallback 接口的实例对象 此处实现该接口的为本类 所以为 this
接下来是客户端代码
<?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" title="Red5 Connect Test" creationComplete="appinit()"> <mx:Script> <![CDATA[ import mx.controls.Alert; 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; var command:String="rtmp://localhost/red5Demo2"; var mync:NetConnection=new NetConnection(); var client1:Object = new Object(); function netStatusHandler(sevt:NetStatusEvent):void{ } function appinit(){ mync.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler); } function serverConnect():void{ out_txt.text="Connectting ... ..."; client1.clientMethod = this.clientMethod; mync.client = this.client1; mync.connect(command); trace("serverConnect:"+command); } public function clientMethod(str:String, num:Number):String{ Alert.show("str: "+ str +" num:" + num); return "客户端方法被调用...."; } ]]> </mx:Script> <mx:Style> WindowedApplication { background-color:"0xffffff"; background-alpha:"0.5"; } </mx:Style> <mx:Label y="100" text="连接状态:未连接" horizontalCenter="0" fontSize="12" fontWeight="normal" id="out_txt" condenseWhite="true" height="150"/> <mx:Button y="254" label="点击我连接Red5" fontSize="11" fontWeight="normal" horizontalCenter="0" click="serverConnect()"/> </mx:WindowedApplication>
当连接服务端后 服务端会调用客户端的clientMethod 方法 弹出对话框
到此服务端调用客户端方法的例子结束
