Red5研究与积累（一）

前段时间一直想研究Red5 但是发现网上的很多例子 和配置的方法都跑不通?

不知道是我Red5版本问题 还是JDK编译问题

?

先说下我的环境 JDK1.6 MyEclipse7.5 Red5 0.9.0 windows安装版

安装没什么特别好说的 如果你想设置成服务 就勾上 影响都不大 我一般是手动启动Red5的

?

先从最基本的 连接开始

先写Java 端 MyEclipse 新建一个Web工程 Path 加入Red5 lib 文件夹下的jar 不过除了 servlet *.jar 和 jsp* .jar 别忘了外面的 red5.jar

?

新建一个Java 类 一般命名为 Application 让它继承 ApplicationAdapter Java代码如下

public class Application extends ApplicationAdapter  {private Logger log = Red5LoggerFactory.getLogger(Application.class,"myDemo");private IScope appScope;private IServerStream serverStream;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");return true;}public void appDisconnect(IConnection conn) {log.info("myDemo appDisconnect");if((this.appScope == conn.getScope()) && (this.serverStream != null)){this.serverStream.close();}super.appDisconnect(conn);}}

?

无非是连接上 打印一些日志 和控制台打印一些字符串

?

接着是Flex 端

?

<?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/myDemo";//这里注意修改地址为你的red5服务器地址  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);  }  ]]></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>

?

再来看最关键的配置文件

?

web.xml

?

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">  <display-name>myDemo</display-name><context-param><param-name>webAppRootKey</param-name><param-value>/myDemo</param-value></context-param>     <listener>        <listener-class>org.red5.logging.ContextLoggingListener</listener-class>    </listener>        <filter>        <filter-name>LoggerContextFilter</filter-name>        <filter-class>org.red5.logging.LoggerContextFilter</filter-class>    </filter>        <filter-mapping>        <filter-name>LoggerContextFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>       <servlet><servlet-name>rtmpt</servlet-name><servlet-class>org.red5.server.net.rtmpt.RTMPTServlet</servlet-class><load-on-startup>1</load-on-startup></servlet>    <servlet-mapping><servlet-name>rtmpt</servlet-name><url-pattern>/fcs/*</url-pattern></servlet-mapping><servlet-mapping><servlet-name>rtmpt</servlet-name><url-pattern>/open/*</url-pattern></servlet-mapping><servlet-mapping><servlet-name>rtmpt</servlet-name><url-pattern>/close/*</url-pattern></servlet-mapping><servlet-mapping><servlet-name>rtmpt</servlet-name><url-pattern>/send/*</url-pattern></servlet-mapping><servlet-mapping><servlet-name>rtmpt</servlet-name><url-pattern>/idle/*</url-pattern></servlet-mapping>        <security-constraint>        <web-resource-collection>            <web-resource-name>Forbidden</web-resource-name>            <url-pattern>/streams/*</url-pattern>        </web-resource-collection>        <auth-constraint/>    </security-constraint></web-app>

将工程发布到Red5的 webapps 文件夹下? 命名为你定义的名字 这里我的是 myDemo?

?

到这里 已经完成最简单的Demo 了
