MVC3: Custom AuthorizeAttribute - asp.net-mvc-3

Question

I am implementing a Custom Authorize Attribute in MVC3. I am storing page level permissions in the database, and would like to pass my authorize attribute a Page ID. Something of the sort:
[CustomAuthorize(PageID = 1)]
public ActionResult About()
{
return View();
}
How do I implement the Authorize Attribute, as the AuthorizeCore only takes one argument in the override?
public class CustomAuthorizeAttribute : AuthorizeAttribute
{
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
}
}

Answer 1

You would define a class-level variable to hold the PageID, and your attribute's constructor would take that as an argument. Or to use it like you have in your example, you would create a public property called PageID.
public class CustomAuthorizeAttribute : AuthorizeAttribute
{
public int PageID{get; set;}
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
//use PageID to do checks here.
}
}
Then within your AuthorizeCore, you would use that property/field value to do your checks.

(Custom User Type ) Just some tweaking
Test Controller
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace Authorise.Controllers
{
public class TestController : Controller
{
// GET: /Default1/
[CustomAuthorize(UserType = "Admin")]
public ActionResult Index()
{
return View();
}
}
public class CustomAuthorizeAttribute : AuthorizeAttribute
{
public string UserType { get; set; }
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
if (UserType == "Admin")
{
return true;
}
else
{
return false;
}
}
}
}
Test View
#{
ViewBag.Title = "Test";
}
<h2>Test</h2>
Account Controller
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace Authorise.Controllers
{
public class AccountController : Controller
{
//
// GET: /Account/
public ActionResult Index()
{
return View();
}
public ActionResult LogOn()
{
return View();
}
}
}
Account Logon View
#{
ViewBag.Title = "LogOn";
}
LogOn
