Can you enable [Authorize] for controller but disable it for a single action?

Question

I would like to use [Authorize] for every action in my admin controller except the Login action.

[Authorize (Roles = \"Administrator\"         


        

Answer 1

You could override the OnAuthorization method of the controller

    protected override void OnAuthorization(AuthorizationContext filterContext)
    {
        if ((string)(filterContext.RouteData.Values["action"]) == "Login")
        {
            filterContext.Cancel = true;
            filterContext.Result = Login();
        }
    }

This works but it is a hack.

Full class code used for testing:

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

namespace MvcApplication2.Controllers
{
[HandleError]
[Authorize]
public class HomeController : Controller
{
    public ActionResult Index()
    {
        ViewData["Title"] = "Home Page";
        ViewData["Message"] = "Welcome to ASP.NET MVC!";

        return View();
    }


    public ActionResult About()
    {
        ViewData["Title"] = "About Page";

        return View();
    }


    protected override void OnAuthorization(AuthorizationContext filterContext)
    {
        if ((string)(filterContext.RouteData.Values["action"]) == "Index")
        {
            filterContext.Cancel = true;
            filterContext.Result = Index();
        }
    }
}
}
