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：

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

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

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

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

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

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;
        }
        
        
    }
}
