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。
