flex中怎么获取cookie

Answer 1

<%@ Page Language="C#" EnableEventValidation="false" ResponseEncoding="utf-8"%>

<% //读取Cookie
HttpCookieCollection cookieColl = Request.Cookies;
//获取其中名为VisitorCount的Cookie
HttpCookie oCookie = cookieColl["VisitorCount"];
//检查该Cookie是否存在，如果不存在就新建一个
//也就是第一次访问
if (oCookie == null)
{
HttpCookie newCookie = new HttpCookie("VisitorCount", "1");
newCookie.Expires = DateTime.Now.AddYears(1);
Response.Cookies.Add(newCookie);
}
else
{
//如果存在就更新
oCookie.Value = "" + (Convert.ToInt32(oCookie.Value) + 1);
Response.Cookies.Set(oCookie);
}
//返回更新后的值给FLEX
Response.Write(cookieColl["VisitorCount"].Value);

以下为FLEX4.5的代码：
