How to get request die cookies in Web-API Autorisierungs-Attribut?

In .NET gibt es zwei AuthorizeAttribute Klassen. Definiert man in System.Web.Http namespace:

namespace System.Web.Http
{
    //Summary:
    //    Specifies the authorization filter that verifies the request's System.Security.Principal.IPrincipal.
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class AuthorizeAttribute : AuthorizationFilterAttribute
    {
        //Summary:
        //    Initializes a new instance of the System.Web.Http.AuthorizeAttribute class.
        public AuthorizeAttribute();

        //Summary:
        //    Gets or sets the authorized roles.
        //
        //Returns:
        //    The roles string.
        public string Roles { get; set; }
        //
        //Summary:
        //    Gets a unique identifier for this attribute.
        //
        //Returns:
        //    A unique identifier for this attribute.
        public override object TypeId { get; }
        //
        //Summary:
        //    Gets or sets the authorized users.
        //
        //Returns:
        //    The users string.
        public string Users { get; set; }

        //Summary:
        //    Processes requests that fail authorization.
        //
        //Parameters:
        //  actionContext:
        //    The context.
        protected virtual void HandleUnauthorizedRequest(HttpActionContext actionContext);
        //
        //Summary:
        //    Indicates whether the specified control is authorized.
        //
        //Parameters:
        //  actionContext:
        //    The context.
        //
        //Returns:
        //    true if the control is authorized; otherwise, false.
        protected virtual bool IsAuthorized(HttpActionContext actionContext);
        //
        //Summary:
        //    Calls when an action is being authorized.
        //
        //Parameters:
        //  actionContext:
        //    The context.
        //
        //Exceptions:
        //  System.ArgumentNullException:
        //    The context parameter is null.
        public override void OnAuthorization(HttpActionContext actionContext);
    }
}

Anderen definiert in System.Web.Mvc namespace:

namespace System.Web.Mvc
{
    //Summary:
    //    Specifies that access to a controller or action method is restricted to users
    //    who meet the authorization requirement.
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class AuthorizeAttribute : FilterAttribute, IAuthorizationFilter
    {
        //Summary:
        //    Initializes a new instance of the System.Web.Mvc.AuthorizeAttribute class.
        public AuthorizeAttribute();

        //Summary:
        //    Gets or sets the user roles that are authorized to access the controller
        //    or action method.
        //
        //Returns:
        //    The user roles that are authorized to access the controller or action method.
        public string Roles { get; set; }
        //
        //Summary:
        //    Gets the unique identifier for this attribute.
        //
        //Returns:
        //    The unique identifier for this attribute.
        public override object TypeId { get; }
        //
        //Summary:
        //    Gets or sets the users that are authorized to access the controller or action
        //    method.
        //
        //Returns:
        //    The users that are authorized to access the controller or action method.
        public string Users { get; set; }

        //Summary:
        //    When overridden, provides an entry point for custom authorization checks.
        //
        //Parameters:
        //  httpContext:
        //    The HTTP context, which encapsulates all HTTP-specific information about
        //    an individual HTTP request.
        //
        //Returns:
        //    true if the user is authorized; otherwise, false.
        //
        //Exceptions:
        //  System.ArgumentNullException:
        //    The httpContext parameter is null.
        protected virtual bool AuthorizeCore(HttpContextBase httpContext);
        //
        //Summary:
        //    Processes HTTP requests that fail authorization.
        //
        //Parameters:
        //  filterContext:
        //    Encapsulates the information for using System.Web.Mvc.AuthorizeAttribute.
        //    The filterContext object contains the controller, HTTP context, request context,
        //    action result, and route data.
        protected virtual void HandleUnauthorizedRequest(AuthorizationContext filterContext);
        //
        //Summary:
        //    Called when a process requests authorization.
        //
        //Parameters:
        //  filterContext:
        //    The filter context, which encapsulates information for using System.Web.Mvc.AuthorizeAttribute.
        //
        //Exceptions:
        //  System.ArgumentNullException:
        //    The filterContext parameter is null.
        public virtual void OnAuthorization(AuthorizationContext filterContext);
        //
        //Summary:
        //    Called when the caching module requests authorization.
        //
        //Parameters:
        //  httpContext:
        //    The HTTP context, which encapsulates all HTTP-specific information about
        //    an individual HTTP request.
        //
        //Returns:
        //    A reference to the validation status.
        //
        //Exceptions:
        //  System.ArgumentNullException:
        //    The httpContext parameter is null.
        protected virtual HttpValidationStatus OnCacheAuthorization(HttpContextBase httpContext);
    }
}

Wichtigsten Unterschiede zwischen diesen beiden sind:

  • System.Web.Http version kann verwendet werden, die von Web API
  • System.Web.Mvc version verwendet werden kann ASP.NET MVC
  • Http version verwenden HttpActionContext parameter Typ in OnAuthorization Methode, wenn Mvc version verwenden AuthorizationContext geben.

Möchte ich Antrag auf Zugang cookies in Http version von AuthorizeAttribute. In Mvc - version ist es wie folgt implementiert:

public class Foo : AuthorizeAttribute
{
     public override void OnAuthorization(AuthorizationContext filterContext) 
     {
          HttpCookie cookie = filterContext.HttpContext.Request.Cookies.Get("Bar");    
     }
}

Weiß jemand, wie kann ich das gleiche tun mit HttpActionContext? Ist es überhaupt möglich? Wenn es nicht möglich ist - warum ist es so?
