Flex连接FMS实现用户列表（使用SharedObject）

1.先在FMS的安装目录中添加自己的应用（例如我的目录D:\Macromedia\Flash Media Server 2\applications），在applications目录下建立文件夹userList。

2.用文本编辑器编写服务器端脚本main.asc文件，内容如下：

js 代码

1. application.onAppStart = function()   
2. {   
3.     userList_so = SharedObject.get ("userList","false");   
4. }   
5. application.onConnect = function(client,userName)   
6. {   
7.     client.userName = userName;   
8.     userList_so.setProperty (userName, userName);   
9.     return true;   
10. }   
11.   
12. application.onDisconnect = function(client)   
13. {   
14.     userList_so.setProperty(client.userName,null);   
15. }  

 

3.编写客户端应用userList.mxml，内容如下：

xml 代码

1. xml version="1.0" encoding="utf-8"?>  
2. <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="initApp();">  
3.     <mx:Label x="79" y="63" text="User Name:" fontWeight="bold" fontStyle="italic"/>  
4.     <mx:TextInput x="155" y="61" id="txtUserName"/>  
5.     <mx:Button x="82" y="89" label="Connect To Flash Media Server" width="233" fontWeight="bold" fontStyle="italic" click="connectServer();"/>  
6.     <mx:List x="82" y="145" width="233" height="252" id="listUserList" labelField="userName">mx:List>  
7.     <mx:Label x="82" y="119" text="User List:" fontWeight="bold" fontStyle="italic"/>  
8.     <mx:Script>
