  • SharedObject使用:在FluorineFx.net与Flex中使用共享对象维护在线用户列表实例【转】

    一、添加一个新的FluorineFx的服务类项目OnLineService,删除原有的Sample.cs,并添加一个用户类定义与一个ApplicationAdpater类:如下:

    /*-- User.cs --*/

    namespace OnLineService

    {

      public class User

      {

        public string UserName { get; set; }

        public string UserPsw { get; set; }

      }

    }

    /* --  ApplicationAdapter类:DemoApp.cs --*/

    using FluorineFx;

    using FluorineFx.Messaging.Adapter;

    using FluorineFx.Messaging.Api;

    using FluorineFx.Messaging.Api.SO;

    namespace OnLineService

    {

        /// <summary>

        /// Fluorine sample service.

        /// </summary>

        [RemotingService("用户登录状态测试程序")]

        public class DemoApp:ApplicationAdapter

        {

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

            {

                string userName = parameters[0] as string;

                string password = parameters[1] as string;

                // 这里可以自定义登录判断验证逻辑,此处只要密码为000即可进入

                if (password != "000")

                    return false;

                // 将当前连接添加一个userName属性与当前登录用户关联起来

                // 以便此连接掉线时,可以准确定位到其相关用户

                connection.Client.SetAttribute("userName", userName);

                //获取共享对象(OnLineUsers)

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

                if (users_so == null)

                {

                    //第一个用户时共享对象不存在,需创建

                    CreateSharedObject(connection.Scope, "OnLineUsers", false);

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

                }

                //更新共享对象key为用户名,value为用户对象

                //value可以为更复杂的对象,但尽量不要打包List或array,因为Flex端解包不易

                users_so.SetAttribute(userName, new User() { UserName = userName, UserPsw = password });

                return true;

            }

            public override void AppDisconnect(IConnection connection)

            {

                string userName = connection.Client.GetAttribute("userName") as string;

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

                if (users_so != null)

                {

                    //从共享对象中移除当前退出系统用户

                    users_so.RemoveAttribute(userName);

                }

                base.AppDisconnect(connection);

            }

        }

    }

     

    二、在解决方案中添加一个Fluorine.net Web项目

    2.1 在Web根目录下添加apps文件夹,apps下添加OnLineUser文件夹,OnLineUser文件夹下添加app.config配置文件,其下配置应用程序处理为上面定义的DemoApp,如下:

     

    2.2 修改WEB-INF下的service-config.xml,打开其my-rtmp信道配置节(fluorineFx添加的web项目时,默认会将此节注释掉,打开即可)

    2.3 在根目录下添加Flex文件下,其下加入libs、src、swf三个子文件夹,将fds.swc拷入libs文件夹,其它两个文件夹在后面的步骤中分别用作 Flex项目的源文件与输出文件目录。

    项目的文件组织如下:

    三、在Flex Builder3中新建项目OnLineUserDemo,项目路径为2.3中的Flex文件夹,配置测试服务器为asp.net,WebRootUrl路径为vs运行网站时的路径,如下图中的兰色部分:

    3.1 右击flex项目的属性(Properties),

    配置FlexBuilderPath如下:

    配置FlexCompier的参数如下:

    注:上面的“E:..”请换成你本地项目中services-config.xml对应的路径(包括下面的Server配置)

    配置FlexServce的参数如下:

    3.2 以下为OnLineUserDemo.mxml源代码:

    <?xml version="1.0" encoding="utf-8"?>

    <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" 

        width="600" height="382" backgroundGradientAlphas="[1.0, 1.0]"

        backgroundGradientColors="[#000000, #049FF1]" fontSize="12">

        <mx:Script>

            <![CDATA[

                import mx.controls.Alert;

                import mx.messaging.config.ServerConfig;

                private function connectionServer(event:MouseEvent):void

                {  

                        var endpoint:String=ServerConfig.getChannel("my-rtmp").endpoint;        

                    nc = new NetConnection();

                    nc.connect(endpoint+"/OnLineUser",this.txtUserName.text,this.txtPassword.text);

                    nc.addEventListener(NetStatusEvent.NET_STATUS,onStatusHandler);

                    nc.client = this; 

                }

               

                private function onStatusHandler(event:NetStatusEvent):void

                {

                    this.connStatus.text = "连接状态:" + event.info.code;

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

                    {

                        //连接远程共享对象

                        so = SharedObject.getRemote("OnLineUsers",nc.uri,false);

                        if(so)

                        {

                            so.addEventListener(SyncEvent.SYNC,onSyncHandler);

                            so.connect(nc);

                            so.client = this;

                        }

                        onCallClient("用户【 <font color="#FF0000">"+this.txtUserName.text+"</font>】登陆了系统!");

                    }

                }

               

                private function onSyncHandler(event:SyncEvent):void

                {

                    var temp:Array = new Array();

                    //so.data中每一个元素即服务器端维护的每一个attribute

                    for(var u:Object in so.data)

                    {

                        temp.push(so.data[u]);

                    }

                    this.dgUserList.dataProvider = temp;

                }

                private function onCallClient(message:String):void

                {

                    so.send("writeMsg",message); 

                    //所以通过so的send方法,可以同时调用每个客户端的writeMsg程序,类似发送广播

                }

               

                //writeMsg一定要为public,否则so调用不到

                public function writeMsg(message:Object):void

                {

                    var param:String=message.toString();

                    txtTraceArea.htmlText += param + " ";

                    txtTraceArea.validateNow();

                    txtTraceArea.verticalScrollPosition = txtTraceArea.maxVerticalScrollPosition;

                }
