[HttpPost]
        public ActionResult CheckLogin(User model)
        {
            if (!ModelState.IsValid)
                return null;

            string userData=new JavaScriptSerializer().Serialize(model);

            FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,model.LoginName,DateTime.Now,DateTime.Now.AddMinutes(2),false,userData);
            string cookieValue = FormsAuthentication.Encrypt(ticket);
            HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName,cookieValue);
            HttpContext.Response.Cookies.Add(cookie);
            //var userData = new MyUserDataPrincipal { UserId=1};
            //MyFormsAuthentication<MyUserDataPrincipal>.SetAuthCookie("s", userData, true);
            return View();
        }

以上是发送cookie的代码

protected void Application_PostAuthenticateRequest(object sender, System.EventArgs e)
        {
            HttpCookieCollection cookieCollection= HttpContext.Current.Request.Cookies;
            string [] cookieArray=cookieCollection.AllKeys;
            HttpCookie cookie = cookieCollection.Get(FormsAuthentication.FormsCookieName);
        }

以上是接收请求的cookie的代码得到的cookie的值永远是null 拿不到cookie

下面MVC最外层的web.config代码
