as3与red5通信---学习三-优快云博客

本文介绍了一个简单的聊天室组件实现过程，分为五步：创建Flash聊天室元件、编写绑定类、客户端连接类、服务端类，并将元件放置到主场景中。通过这些步骤，实现了消息的发送、接收及广播。

第一步：新建元件

包括三部分

1.消息显示区，命名为show_txt

2.消息发送区命名为sent_txt

3.发送按钮,命名为sent_btn

并绑定类 CharRoom

第二步：编写绑定类

package test2{
    import fl.controls.TextArea;
    import fl.controls.TextInput;

    import flash.display.DisplayObject;
    import flash.display.MovieClip;
    import flash.events.MouseEvent;

    public class ChatRoom extends MovieClip{

    private var netclient:NetClient ;
    public function ChatRoom(){
       super();

       //发送按钮
       send_btn.addEventListener(MouseEvent.CLICK,sendMessage);

       //连接服务端的
       netclient = new NetClient(this);
     }

     /**
       *服务端调用此方法来更新消息列表
      */
    public function receiveBroadMes(mes:Object):void{

        /*
         *显示窗口加入消息 ,并且清空发送窗口
         *因为和元件绑定所以直接访问实例名:show_txt
          */

show_txt.appendText(mes+"\n");
send_txt.text = "" ;

}

    /**
       * 当点击发送按钮的时候，发送消息
       */

    private function sendMessage(e:MouseEvent):void{
        this.netclient.broadcastMes(send_txt.text);
    }
}
}

第三步：编写客户端连接类

package test2{
import flash.events.NetStatusEvent;
import flash.net.NetConnection;

    import flash.net.ObjectEncoding;

    public class NetClient extends NetConnection
    {
        private var chatroom:ChatRoom ;
        public function NetClient(chatroom:ChatRoom)    {
            this.chatroom = chatroom ;

            this.objectEncoding = ObjectEncoding.AMF0;

            this.addEventListener(NetStatusEvent.NET_STATUS , netStatus);

            this.connect("rtmp://192.168.0.20/red5_server");

  }
    /**
       * 服务端调用此方法
       * 更新显示窗口
       */

    public function updateMes(obj:Object){
        trace("test call back ...."+obj);
        this.chatroom.receiveBroadMes(obj);
}


     /**
      * 一个客户端发消息所以客户端都能收到
      * 调用服务端的广播方法
      * 通知所有的在线用户
      * @param mes 要发送的信息
      */

    public function broadcastMes(mes:String):void{
        this.call("broadcastMes",null,mes);
     }


  // 网络连接情况

    private function netStatus (event:NetStatusEvent):void{
        trace("net connection case is ........."+event.info.code);
   }

}
}

第四步：编写服务端类

package test;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.red5.server.adapter.ApplicationAdapter;
import org.red5.server.api.IClient;
import org.red5.server.api.IConnection;
import org.red5.server.api.IScope;
import org.red5.server.api.Red5;
import org.red5.server.api.service.IServiceCapableConnection;
public class NetServer extends ApplicationAdapter{

private static final Log log = LogFactory.getLog(TestCon.class);

public NetServer(){

}

/**
* broadcast the message .notify all client
*/

public boolean broadcastMes(String message){
  log.info("receive message is "+message) ;
  log.info("server trace 1..............") ;
  IConnection currentcon = Red5.getConnectionLocal();

  IScope scope = currentcon.getScope();

  Iterator<IConnection> conns = scope.getConnections();

  /*
   * loop all the online user then broadcase message .
   */
   while(conns.hasNext()){
   IConnection conn = conns.next();
   if(conn instanceof IServiceCapableConnection){
           IServiceCapableConnection iservice = (IServiceCapableConnection)conn ;
           iservice.invoke("updateMes",new Object[]{message});
         }
     }
   log.info("server trace 2..............") ;

  return true ;
}

}
