ASP.Net MVC 3 – 密码保护视图

>使用动作过滤器装饰控制器/动作,例如：[SimpleMembership]
>在该动作过滤器上,只检查会话变量的存在和内容
>如果不是正确的,则重定向到SignIn

在代码中：

public class SimpleMembershipAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        //redirect if not authenticated
        if (filterContext.HttpContext.Session["myApp-Authentication"] == null ||
            filterContext.HttpContext.Session["myApp-Authentication"] != "123")
        {
            //use the current url for the redirect
            string redirectOnSuccess = filterContext.HttpContext.Request.Url.AbsolutePath;

            //send them off to the login page
            string redirectUrl = string.Format("?ReturnUrl={0}",redirectOnSuccess);
            string loginUrl = "/Protected/SignIn" + redirectUrl;
            filterContext.HttpContext.Response.Redirect(loginUrl,true);
        }
    }
}

和你的控制器

public class ProtectedController : Controller
{
    [SimpleMembership]
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult SignIn()
    {
        return View();
    }
    [HttpPost]
    public ActionResult SignIn(string pwd)
    {
        if (pwd == "123")
        {
            Session["myApp-Authentication"] = "123";
            return RedirectToAction("Index");
        }
        return View();
    }
}

如果你想装饰整个控制器,你需要将SignIn方法移到外面以便到达那里,你需要进行身份验证.
