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。
