asp.net-mvc – MVC角色授权

我正在尝试实现角色授权机制,该机制检查当前登录用户的角色,如果用户处于正确的角色,他/她被允许,否则显示错误视图.

问题是当用户尝试访问控制器中的以下方法时,他确实进入了RoleAuthorizationAttribute类并获得验证,但是控制器中的方法未被执行.

注意：用户具有客户角色

控制器方法

[RoleAuthorization(Roles = "Client,Adminsitrator")]
    public ActionResult addToCart(int ProductID,string Quantity)
    {
        tempShoppingCart t = new tempShoppingCart();
        t.ProductID = ProductID;
        t.Username = User.Identity.Name;
        t.Quantity = Convert.ToInt16(Quantity);

        new OrdersService.OrdersClient().addToCart(t);
        ViewData["numberOfItemsInShoppingCart"] = new OrdersService.OrdersClient().getNoOfItemsInShoppingCart(User.Identity.Name);
        ViewData["totalPriceInSC"] = new OrdersService.OrdersClient().getTotalPriceOfItemsInSC(User.Identity.Name);
        return PartialView("quickShoppingCart","Orders");
    }

角色验证类

[System.AttributeUsage(System.AttributeTargets.All,AllowMultiple = false,Inherited = true)]
public sealed class RoleAuthorizationAttribute : AuthorizeAttribute
{
    public override void OnAuthorization(AuthorizationContext filterContext)
    {


        List<String> requiredRoles = Roles.Split(Convert.ToChar(",")).ToList();

        List<Role> allRoles = new UsersService.UsersClient().GetUserRoles(filterContext.HttpContext.User.Identity.Name).ToList();


        bool Match = false;

        foreach (String s in requiredRoles)
        {
            foreach (Role r in allRoles)
            {
                string rName = r.RoleName.Trim().ToString();
                string sName = s.Trim();
                if (rName == sName)
                {
                    Match = true;
                }
            }
        }

        if (!Match)
        {
            filterContext.Result = new ViewResult { ViewName = "AccessDenied" };
        }

        base.OnAuthorization(filterContext);

    }
}

你能告诉我我做错了什么

解决方法

protected void Application_AuthenticateRequest(object sender,EventArgs args)
    {
        if (Context.User != null)
        {
            IEnumerable<Role> roles = new UsersService.UsersClient().GetUserRoles(
                                                    Context.User.Identity.Name);


            string[] rolesArray = new string[roles.Count()];
            for (int i = 0; i < roles.Count(); i++)
            {
                rolesArray[i] = roles.ElementAt(i).RoleName;
            }

            GenericPrincipal gp = new GenericPrincipal(Context.User.Identity,rolesArray);
            Context.User = gp;
        }
    }

然后我可以使用正常

[Authorize(Roles = "Client,Administrator")]

在控制器中的actionResult方法之上

这工作.
