1.HomeController.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MvcAuthorizeTest.Models;
using System.Web.Security;

namespace MvcAuthorizeTest.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/

        public ActionResult Index()
        {
            return View();
        }
        public ActionResult Login()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Login(LoginModel login)
        {
            if (login.UserName == "admin" && login.Password == "123456")
            {
                FormsAuthentication.SetAuthCookie(login.UserName, false);
                return Redirect("/Home/ChangePassword");
            }

            return View();
        }

        public ActionResult ChangePassword()
        {
           return View();
        }

        [Authorize]
        public ActionResult Logout()
        {
            FormsAuthentication.SignOut();
            return Redirect("/Home/Login");
        }

        [Authorize]
        public ActionResult ShowDetails()
        {
            return View();
        }

        [Authorize]
        [MyAuthorizeAttribute]
        public ActionResult ShowDetails2()
        {
            return View();
        }

        public ActionResult ShowTip()
        {
            return View();
        }
    }
}

2.Models目录下的文件:

LoginModel.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MvcAuthorizeTest.Models
{
    public class LoginModel
    {
        public string UserName { set; get; }
        public string Password  { set; get; }
    }
}

MyAuthorizeAttribute.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MvcAuthorizeTest.Models
{
    public class MyAuthorizeAttribute : AuthorizeAttribute
    {

        protected override bool AuthorizeCore(HttpContextBase httpContext)
        {
            //return base.AuthorizeCore(httpContext);
            return DateTime.Now.Minute % 2 == 0;
        }

        protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
        {
            filterContext.HttpContext.Response.Redirect("/Home/ShowTip");

            //base.HandleUnauthorizedRequest(filterContext);
        }
    }

}

3.Views/Home目录下的View文件如下:

    ViewBag.Title = "Index";
}

<h2>Index</h2>
@Html.ActionLink("Login","Login")
@Html.ActionLink("Logout","Logout")
<hr />
@Html.ActionLink("ShowDetails", "ShowDetails")
@Html.ActionLink("ShowDetails2", "ShowDetails2")

Login.cshtml:

@model MvcAuthorizeTest.Models.LoginModel

@{
    ViewBag.Title = "Login";
}

<h2>Login</h2>

@using (Html.BeginForm("Login","Home",FormMethod.Post)) {
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>LoginModel</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.UserName)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.UserName)
            @Html.ValidationMessageFor(model => model.UserName)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Password)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Password)
            @Html.ValidationMessageFor(model => model.Password)
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>

    </authentication>
