Question

早些时候我遇到了类似的问题。我创建了asp mvc 默认模板项目并在home控制器上设置了authorization属性。当我运行app url时：

http://localhost:48403/Account/LogOn?ReturnUrl=%2f

当用户未经过身份验证时，我尝试获得的只是http://localhost:48403，但我对重新安装设置没有运气:( 我试图把它放在global.asax中，但没有运气：

routes.MapRoute("Login", "",
                 new { controller = "Account", action = "LogOn" }
             );

这是我的全部global.asax

routes.MapRoute("About", "About",
                 new { controller = "Home", action = "About" }
             );

            routes.MapRoute("Login", "",
                 new { controller = "Account", action = "LogOn" }
             );

            routes.MapRoute(
                "Default", // Route name
                "{controller}/{action}/{id}", // URL with parameters
                new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
            );

你可以编写一个自定义的Authorize属性，相反，如果重定向将直接呈现LogOn视图：

public class MyAuthorizeAttribute : AuthorizeAttribute
{
    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {
        var viewResult = new ViewResult
        {
            ViewName = "~/Views/Account/LogOn.cshtml"
        };
        filterContext.Result = viewResult;
    }
}

然后用它装饰你的HomeController：

[MyAuthorize]
public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }
}

然后你的AccountController不再需要担心ReturnUrls：

public class AccountController : Controller
{
    [HttpPost]
    public ActionResult LogOn(LogOnModel model)
    {
        if (ModelState.IsValid)
        {
            if (Membership.ValidateUser(model.UserName, model.Password))
            {
                FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);
                // TODO: obviously here instead of hardcoding the country and the city
                // you might want to retrieve them from your backend given the username
                return RedirectToAction("Index", "Home", new { country = "uk", city = "london" });
            }
            else
            {
                ModelState.AddModelError("", "The user name or password provided is incorrect.");
            }
        }

        return View(model);
    }

    public ActionResult LogOff()
    {
        FormsAuthentication.SignOut();
        return RedirectToAction("Index", "Home");
    }
}

最后你需要在〜/ Views / Account / LogOn.cshtml中修改表单的动作以指向正确的控制器：

@using (Html.BeginForm("LogOn", "Account")) {
    ...
}

您可以默认离开路线：

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        "Default",
        "{controller}/{action}/{id}",
        new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}
