Sun公司开源游戏服务器Project Darkstar Server(SGS)-----AS3客户端

1、sgs的AS3客户端有两个版本的alienos和sun官方的beyondo。我这里使用的是sun官方网站上的darkstar-as-client，里面的项目结构如下：

2、服务端代码：

 MainApp.java：

 

代码

package  net.papaya;

import  java.io.Serializable;
import  java.util.Properties;
import  java.util.logging.Level;
import  java.util.logging.Logger;

import  com.sun.sgs.app.AppListener;
import  com.sun.sgs.app.ClientSession;
import  com.sun.sgs.app.ClientSessionListener;

public   class  MainApp  implements  Serializable, AppListener {

     /**
     * 
      */
     private   static   final   long  serialVersionUID  =   1L ;
     private   static   final  Logger logger = Logger.getLogger(MainApp. class .getName());
    

     public   void  initialize(Properties arg0) {
         //  TODO Auto-generated method stub
        logger.log(Level.INFO,  " 程序已经启动了... " );
    }

     public  ClientSessionListener loggedIn(ClientSession session) {
         //  TODO Auto-generated method stub
         return   new  UserClientSessionListener(session);
    }

}

UserClientSessionListener.java

代码

package  net.papaya;

import  java.io.Serializable;
import  java.nio.ByteBuffer;
import  java.util.logging.Level;
import  java.util.logging.Logger;

import  com.sun.sgs.app.AppContext;
import  com.sun.sgs.app.ClientSession;
import  com.sun.sgs.app.ClientSessionListener;
import  com.sun.sgs.app.ManagedReference;

public   class  UserClientSessionListener  implements  Serializable,
        ClientSessionListener {

     /**
     * 
      */
     private   static   final   long  serialVersionUID  =   1L ;
     private   static   final  Logger logger = Logger.getLogger(MainApp. class .getName());
     private   final  ManagedReference < ClientSession >  sessionRef;
     private   final  String sessionName;
    
     public   UserClientSessionListener(ClientSession session)
    {
         if (session == null )
        {
            
             throw   new  NullPointerException( " session is null " );
        }
        sessionRef = AppContext.getDataManager().createReference(session);
        sessionName = session.getName();
        
        logger.log(Level.INFO,  " User {0} logger in " ,sessionName);
    }
    
     public  ClientSession getSession()
    {
        
         return  sessionRef.get();
    }
    
    
     public   void  disconnected( boolean  arg0) {
         //  TODO Auto-generated method stub

    }

     public   void  receivedMessage(ByteBuffer message) {
         //  TODO Auto-generated method stub
         this .getSession().send(message);
    }

}

3、客户端：

客户端主类client

代码

package  net.papaya
{
     import  com.beyondo.sgs.client.client.ClientChannel;
     import  com.beyondo.sgs.client.client.ClientChannelListener;
     import  com.beyondo.sgs.client.client.simple.SimpleClient;
     import  com.beyondo.sgs.client.client.simple.SimpleClientListener;
     import  com.beyondo.sgs.client.impl.client.comm.ClientConnector;
     import  com.beyondo.sgs.util.PasswordAuthentication;
     import  com.beyondo.util.BeyondoByteArray;
    
     import  flash.events.EventDispatcher;
    
     import  net.papaya.event.ExecptionEvent;
     import  net.papaya.event.SGSEvent;
     import  net.papaya.event.TestMessageEvent;

     public   class  Client  extends  EventDispatcher  implements  SimpleClientListener
    {
         private  var _client:SimpleClient;
         private  var _user:PasswordAuthentication;
        
        
         public  function Client()
        {
             this ._client = new  SimpleClient( this );
        }
        
         public  function connect(host:String,port:String): void
        {
            var connectProps:Object = new  Object();
            connectProps[ClientConnector.HOST] = host;
            connectProps[ClientConnector.PORT] = port;
             this ._client.login(connectProps);
        }
        
        
         // 发送数据
         public  function send(message:String): void
        {
            var buf:BeyondoByteArray = new  BeyondoByteArray();
            buf.writeUTF(message);
             this ._client.send(buf);
        }
        
         public  function get passwordAuthentication():PasswordAuthentication
        {
             return   this ._user;
        }
        
         public  function set passwordAuthentication(pauth:PasswordAuthentication): void
        {
             this ._user = pauth;
        }
        
         public  function loggedIn(): void
        {
            trace( " 客户端登录成功 " );
            dispatchEvent( new  SGSEvent(SGSEvent.LOGIN_SUCCESS));
        }
        
         public  function loginFailed(reason:String): void
        {
            trace( " 客户端登录失败 " );
            dispatchEvent( new  SGSEvent(SGSEvent.LOGIN_FAILED));
        }
        
         public  function exceptionThrown(err:String): void
        {
            trace( " 连接出错了 " );
            dispatchEvent( new  ExecptionEvent(err));
            
        }
        
         public  function joinedChannel(channel:ClientChannel):ClientChannelListener
        {
             return   null ;
        }
        
         // 接收客户端的数据
         public  function receivedClientMessage(message:BeyondoByteArray): void
        {
            var str:String = message.readSgsString();
            dispatchEvent( new  TestMessageEvent(TestMessageEvent.MESSAGEEVENT,str));
            
        }
        
         // 从新连接
         public  function reconnecting(): void
        {
        }
        
         public  function reconnected(): void
        {
        }
        
         public  function disconnected(graceful:Boolean, reason:String): void
        {
            trace( " 断开连接 " );
            dispatchEvent( new  SGSEvent(SGSEvent.DISCONNECTED));
        }
        
    }
}

事件类：

SGSEvent

 

代码

package  net.papaya.event
{
     import  flash.events.Event;

     public   class  SGSEvent  extends  Event
    {
         public   static    const  CONNECT_SUCCESS:String = " CONNECT_SUCCESS " ;
         public   static    const  DISCONNECTED:String = " SGSEvent_DISCONNECTED " ;
         public   static    const  LOGIN_SUCCESS:String = " SGSEvent_LOGIN_SUCCESS " ;
         public   static    const  LOGIN_FAILED:String = " SGSEvent_LOGIN_FAILED " ;
        
        
        
         public  function SGSEvent(type:String, bubbles:Boolean = false , cancelable:Boolean = false )
        {
             super (type, bubbles, cancelable);
        }
        
    }
}

 ExecptionEvent：

处理派发socket的异常

 

代码

package  net.papaya.event
{
     import  flash.events.Event;

     public   class  ExecptionEvent  extends  Event
    {
        
         public   static   const  ExecptionThrow = " ExecptionEvent_ExecptionThrow " ;
        
         private  var wrongMsg:String = "" ;
         public  function ExecptionEvent(wrong:String)
        {
             super (ExecptionEvent.ExecptionThrow, false ,  false );
             this .wrongMsg = wrong;
        }
        
         public  function get wrong():String
        {
             return   this .wrongMsg;
        }
         public  function set wrong(str:String): void
        {
             this .wrongMsg = str;
        }
        
    }
}

SocketError

package  net.papaya.event
{
     public   class  SocketError
    {
         public   static   const  Connect_Fail:String = " Error #2031 " ;
         public   static   const  Security_error:String = " Error #2048 " ;

    }
}

TestMessageEvent：处理派发接受到的数据

 

代码

package  net.papaya.event
{
     import  flash.events.Event;

     public   class  TestMessageEvent  extends  Event
    {
         public   static   const  MESSAGEEVENT:String = " TestMessageEvent_MESSAGEeVENT " ;
        
        
         private  var _msg:String = "" ;
         public  function TestMessageEvent(type:String,Eventmessage:String)
        {
             super (type, false ,  false );
             this ._msg = Eventmessage;
        }
        
         public  function get message():String
        {
             return   this ._msg;
        }
        
         public  function set message(msg:String): void
        {
             this ._msg = msg;
        }
        
        
    }
}

 下面是View模块:
