FluorineFx:远程共享对象(Remote SharedObjects)

单纯从客户端上来看，FluorineFx的RSO跟FMS中的RSO几乎没什么不同(参见Flash/Flex学习笔记(15)：FMS 3.5之远程共享对象(Remote Shared Object) )，只不过FMS是Adobe的收费产品，FluorineFx是用于.Net平台的开源免费产品

.

服务端代码：

1、为了防止客户端随意连接或创建任何属性的RSO，服务端可以定义一个用于安全处理的cs文件

using System.Collections;

using FluorineFx.Messaging.Api;

using FluorineFx.Messaging.Api.SO;



namespace _02_SharedObject

{

    public class SampleSOSecurityHandler : ISharedObjectSecurity 

    {

        #region ISharedObjectSecurity Members



        //是否允许连接

        public bool IsConnectionAllowed(ISharedObject so)

        {            

            return true;

        }



        //是否允许创建rso对象(下面的代码仅允许创建名为position的rso对象)

        public bool IsCreationAllowed(IScope scope, string name, bool persistent)

        {

            if (!"position".Equals(name) || !persistent)

                return false;

            else

                return true;

        }



        //是否允许删除

        public bool IsDeleteAllowed(ISharedObject so, string key)

        {

            return false;

        }



        //是否允许rso对象向服务端send指定回调方法(下面的代码仅允许发送名为drop的回调方法)

        public bool IsSendAllowed(ISharedObject so, string message, IList arguments)

        {

            if (!"drop".Equals(message))

            {

                return false;

            }

            else

            {

                //这里把第一个参数处理一下，客户端可以在drop()方法中访问到处理后的参数

                if (arguments.Count > 0) {

                    arguments[0] = "from server ：" + arguments[0];

                }

                return true;

            }

        }



        //rso对象的属性是否可写

        public bool IsWriteAllowed(ISharedObject so, string key, object value)

        {

            return true;

        }



        #endregion

    }

}

2、创建一个ApplicationAdapter(应用适配器)

using FluorineFx.Messaging.Adapter;

using FluorineFx.Messaging.Api;

using FluorineFx.Messaging.Api.SO;





namespace _02_SharedObject

{

    /// <summary>

    /// Summary description for AppHandler.

    /// </summary>

    public class SharedBallApplication : ApplicationAdapter

    {

        public SharedBallApplication()

        {

        }



        public override bool AppStart(IScope application)

        {

            RegisterSharedObjectSecurity(new SampleSOSecurityHandler());//注册刚才定义的安全处理Handler

            return base.AppStart(application);

        }



        /// <summary>

        /// 每当有新客户端连接到服务器时，该方法会被触发

        /// </summary>

        /// <param name="connection"></param>

        /// <param name="parameters"></param>

        /// <returns></returns>

        public override bool AppConnect(IConnection connection, object[] parameters)

        {

            string userName=string.Empty, passWord=string.Empty;



            if (parameters.Length >= 2)

            {

                userName = parameters[0].ToString();//第一个参数当作用户名

                passWord = parameters[1].ToString();//第二个参数当作密码

            }



            if (userName == "jimmy.yang" && passWord == "123456")//安全性校验

            {

                if (base.AppConnect(connection, parameters))

                {

                    //获取共享对象(position)

                    ISharedObject users_so = GetSharedObject(connection.Scope, "position");

                    if (users_so == null)

                    {

                        //创建共享对象

                        CreateSharedObject(connection.Scope, "position", true);

                        users_so = GetSharedObject(connection.Scope, "position");

                    }



                    //更新共享对象

                    users_so.SetAttribute("x", 200);

                    users_so.SetAttribute("y", 200);





                    connection.Client.SetAttribute("clientName", userName); //回传数据到客户端连接



                    return true;

                }

                else {

                    RejectClient("连接失败，请检查服务端是否运行正常!");

                    return false;

                }

            }

            else 

            {

                RejectClient("用户名或密码错误");

                return false;

            }          



             

        }

       

    }

}

最后还要一些配置文件来提供必要的信息，详情见最后的示例源码下载

Flash客户端代码：(几乎跟在FMS环境中完全一样)

import flash.display.StageAlign;

import flash.net.NetConnection;

import flash.events.NetStatusEvent;

import flash.net.SharedObject;

import flash.events.SyncEvent;

import flash.events.MouseEvent;



stage.align = StageAlign.TOP_LEFT;



var nc:NetConnection = new NetConnection();

var ball_so:SharedObject;

var userName:String = "";

var passWord:String = "";

var remoteUrl:String = "";



if (root.loaderInfo.parameters.remotingGatewayPath != null)

{

	remoteUrl = root.loaderInfo.parameters.remotingGatewayPath;

}

else

{

	remoteUrl = "rtmp://localhost:1935/SharedBall";

}



if (root.loaderInfo.parameters.userName != null)

{

	userName = root.loaderInfo.parameters.userName;

}

else

{

	userName = "jimmy.yang";

}



if (root.loaderInfo.parameters.passWord != null)

{

	passWord = root.loaderInfo.parameters.passWord;

}

else

{

	passWord = "123456";

}



this.nc.addEventListener(NetStatusEvent.NET_STATUS,net_status_handler);

this.nc.connect(remoteUrl,userName,passWord);

this.nc.client = this;

this.txtStatus.text = "服务端连接中...";

SharedBall_mc.buttonMode = true;



function net_status_handler(e:NetStatusEvent):void

{

	this.txtStatus.text = "as3 状态：" + e.info.code;

	if (e.info.code == "NetConnection.Connect.Success")

	{

		ball_so = SharedObject.getRemote("position",nc.uri,true);

		this.ball_so.addEventListener(SyncEvent.SYNC,sync_handler);

		this.ball_so.connect(this.nc);

		this.ball_so.client = this;

	}

}





function sync_handler(e:SyncEvent):void

{

	if (ball_so.data.x == undefined || ball_so.data.y == undefined)

	{

		SharedBall_mc.x = 100;

		SharedBall_mc.y = 100;

	}

	else

	{

		SharedBall_mc.x = ball_so.data.x;

		SharedBall_mc.y = ball_so.data.y;

	}

}



SharedBall_mc.addEventListener(MouseEvent.MOUSE_DOWN,mouse_down_handler);



function mouse_down_handler(e:MouseEvent):void

{

	SharedBall_mc.startDrag();

	this.stage.addEventListener(MouseEvent.MOUSE_UP,mouse_up_handler);

	this.stage.addEventListener(MouseEvent.MOUSE_MOVE,mouse_move_handler);

}



function mouse_move_handler(e:MouseEvent):void

{

	ball_so.setProperty("x",this.mouseX);

	ball_so.setProperty("y",this.mouseY);

	trace(ball_so.data.x,ball_so.data.y);

}



function mouse_up_handler(e:MouseEvent):void

{

	SharedBall_mc.stopDrag();

	this.stage.removeEventListener(MouseEvent.MOUSE_UP,mouse_up_handler);

	this.stage.removeEventListener(MouseEvent.MOUSE_MOVE,mouse_move_handler);

	ball_so.send("drop",this.userName);

}





function drop(msg:Object):void{

	this.txtStatus.text = msg.toString();

}

 运行截图：

在这个示例中，小球的坐标来自于服务端的共享对象属性值，所以如果一切顺利，在不同的机器上浏览“嵌入有该swf的页面”，当一台机器上拖动小球时，另一台机器上的小球也会随之运动。
