Get list of custom attributes for current action/controller in ASP.NET MVC

Question

Checking out the sample code from http://lukesampson.com/post/471548689/entering-and-exiting-https-with-asp-net-mvc written for ASP.NET MVC2, I noticed they can check if a custom attribute is applied to the current action or controller by accessing filterContext.ActionDescriptor and filterContext.ActionDescriptor.ControllerDescriptor respectively:

public class ExitHttpsIfNotRequiredAttribute : FilterAttribute, IAuthorizationFilter {
    public void OnAuthorization(AuthorizationContext filterContext) {
        // snip

        // abort if a [RequireHttps] attribute is applied to controller or action
        if(filterContext.ActionDescriptor.ControllerDescriptor.GetCustomAttributes(typeof(RequireHttpsAttribute), true).Length > 0) return;
        if(filterContext.ActionDescriptor.GetCustomAttributes(typeof(RequireHttpsAttribute), true).Length > 0) return;

        // snip
    }
}

What would be the ASP.NET MVC 1 method of checking the action and controller for a custom attribute? In ASP.NET MVC 1 there is no filterContext.ActionDescriptor that I can tell.

Answer 1

This seems to work... is there a better / more proper way in ASP.NET MVC 1?

if (filterContext.Controller.GetType().GetCustomAttributes(typeof(RequireHttpsAttribute), true).Length > 0)
    return;
string action = (string)filterContext.RouteData.Values["action"];
if (!string.IsNullOrEmpty(action) && filterContext.Controller.GetType().GetMethod(action).GetCustomAttributes(typeof(RequireHttpsAttribute), true).Length > 0)
    return;
