我们通常希望给flexViewer框架加上权限，使不同角色的人有不同的权限，怎样做呢？以下是我研究的一种方法，大家看看行不行。
1、改写flexviewer框架com.esri.viewer包下的ViewerContainer.mxml文件。在此文件中声明一个public变量代表配置文件的路径public var config:String;
2、在 private function init():void方法中加入代码configFile = config;
3、改写index.mxml代码如下：<fx:Script>
??<![CDATA[
???
???privatefunction initApp():void{
????lblCheckCode.text=GenerateCheckCode();
???}
???
???protectedfunction Submit_clickHandler(event:MouseEvent):void
???{
????this.currentState= "index";
????if(txtUname.text== "jerry")
????{
?????myViewer.config= "config-all.xml";
????}
????if(txtUname.text== "maorey"){
?????myViewer.config= "config.xml";
????}
????
???}
???
???privatefunction GenerateCheckCode():String{
????varran:Number;
????varnumber:Number;
????varcode:String;
????varcheckcode:String="";
????//生成四为随机数
????for(vari:int=0;i<4;i++){
?????ran=Math.random();
?????number=Math.round(ran*1000);
?????if(number%2==0)
??????code=String.fromCharCode(48+(number));
?????else
??????code=String.fromCharCode(65+(number&));
?????checkcode+=code;
????}
????
????returncheckcode;
???}
??]]>
