第一种方法　　

传值方式

http://host:port/index.jsp#UserID=111

//获取传递参数var browser:IBrowserManager=BrowserManager.getInstance();browser.init();var param:Object=URLUtil.stringToObject(browser.fragment, "&");

我用这种方式在3.2下读不到，但4.0的SDK下是没有问题的

为了保持一致性（我们项目中），我做了兼容，也支持

flex Base64编码中如果有汉字，要用 encodeUTFBytes ，使用UTF-8的编码，由其和其它语言交换数据时。
