Red5研究与积累（二）

做成功了第一个连接服务端的简单例子，现在我们来做一个客户端调用服务端方法的例子

 

客户端依然选择Flex

 

新建一个Web工程

 

配置好环境和配置文件

 

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
	xmlns="http://java.sun.com/xml/ns/j2ee"

red5-web.xml

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<bean id="web.scope" class="org.red5.server.WebScope"

	</bean>

	<bean id="web.handler" class="org.red5.demos.Application" />

	<bean class="org.springframework.scripting.support.ScriptFactoryPostProcessor"/>


</beans>

 

red5-web.properties

 

webapp.contextPath=/red5Demo1
webapp.virtualHosts=*, localhost, localhost:8088, 127.0.0.1:8088

 

 

新建一个Java 类 起名 Application  继承  ApplicationAdapter

 

public class Application extends ApplicationAdapter {

	private IScope appScope;
	
	@Override
	public boolean appConnect(IConnection conn, Object[] params) {
		System.out.println(" app connect ");
		return true;
	}

	@Override
	public void appDisconnect(IConnection conn) {
		System.out.println(" app disconnect ");
		super.appDisconnect(conn);
	}

	@Override
	public boolean appStart(IScope arg0) {
		System.out.println(" app start ");
		this.scope = arg0;
		return true;
	}
	
	public String serverMethod(String str) {
		System.out.println(" server method invoke.. ");
		return str.toUpperCase();
	}

}

 

其中 serverMethod 为给客户端调用的方法 该方法调用时打印一句话 并且将传入的字符串以大写形式返回给客户端

 

在Red5 webapps 文件夹下新建 red5Demo1 文件夹 将项目部署

 

启动Red5 服务器

 

 

接下来是客户端代码

 

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
	<mx:Script>
		<![CDATA[
			import mx.controls.Alert;
			
			private var rtmpurl:String = "rtmp://localhost/red5Demo1";
			private var conn:NetConnection = new NetConnection();
			private var isConnectSuccess:Boolean = false;
			private var resp:Responder = new Responder(resFun);
			
			private function resFun(obj:String):void {
				resIn.text = obj;
			}
			
			private function invoke():void {
				if(isConnectSuccess){
					conn.call("serverMethod", resp , textIn.text);
				}else{
					Alert.show("还没连接到服务器");
				}
			}
			
			private function clickConnect(e:MouseEvent):void {
				conn.addEventListener(NetStatusEvent.NET_STATUS, netStatus);
				conn.connect(rtmpurl);
			}
			
			private function netStatus(e:NetStatusEvent):void {
				if(e.info.code == "NetConnection.Connect.Success"){
					isConnectSuccess = true;
				}
			}
			
		
		]]>
	</mx:Script>
	<mx:Button x="224" y="175" label="Invoke" click="invoke()" />
	<mx:TextInput x="129" y="145" width="212" id="textIn" />
	<mx:Label x="129" y="119" text="" fontSize="12" width="160" id="resIn" />
	<mx:Button x="129" y="175" label="Connect" click="clickConnect(event)" />
</mx:Application>

 

 

点击Connect 按钮连接上服务器  

 

接着在输入框输入英文字母  例如 abc 

点击 Invoke 按钮 即可看到 Label 中文字为输入的英文的大写字符串

 

到此客户端调用服务端方法的例子结束
