[]JSON文件加载成功后，怎么解析成Object对象

res/json/config.json文件内容：
---------------------------------
{"id": 1, "name": "Otto"}

AS测试代码(文档类)：
--------------------------------

package 

{

	import laya.display.Text;

	import laya.net.Loader;

	import laya.utils.Handler;

	

	/**

	 * ...

	 * @author OttoChen

	 */

	public class TestMain 

	{

		private var txt:Text = null;

		

		public function TestMain() 

		{

			Laya.init(800, 800);

			

			txt = new Text();

			txt.mouseEnabled = false;

			txt.overflow = Text.SCROLL;

			txt.size(Laya.stage.width, Laya.stage.height);

			txt.pos(10, 10);

			txt.fontSize = 30;

			txt.wordWrap = true;

			txt.color = "#FF9632";

			Laya.stage.addChild(txt);

			

			var test:Object = JSON.parse('{"id": 0, "name": "Chen"}');

			traceMsg(test['id']);

			traceMsg(test['name']);

			

			

			var jsonURL:String = "res/json/config.json";

			traceMsg("加载: " + jsonURL);

			Laya.loader.load(jsonURL, Handler.create(this, readJsonFinish, [jsonURL]), null, Loader.JSON);

			

		}

		

		private function readJsonFinish(url:String = null):void

		{

			traceMsg("readJsonFinish - 加载成功: " + url);

			

			// 返回的是 * 类型，要不要先解析成字符串类型，那应该怎么转呢??

			var jsonConf:* = Laya.loader.getRes(url);

			

			// 这里直接传入jsonConf对象后，打开浏览器调试发现报错了!!

			var config:Object = JSON.parse(jsonConf);

			

			traceMsg(config['id']);

			traceMsg(config['name']);

			traceMsg("==================");

			

		}

		

		

		private function traceMsg(msg:String = ""):void

		{

			if ( msg != null )

			{

				txt.text += msg + "\n";

				txt.scrollY = txt.maxScrollY;

			}

		}

		

	}



}

输出信息:

加载: res/json/config.json
readJsonFinish - 加载成功: res/json/config.json
...运行到 JSON.parse(jsonConf) 就报错了
