c# - 授权核心不断循环 MVC 4 Web 应用程序

Question

我已经实现了一个自定义属性，它基本上检查用户是否在某个组内。如果是，它会处理未经授权的请求。我遇到的问题是代码不断循环并查找以查明问题。如果我有

我的代码如下：

protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        if (base.AuthorizeCore(httpContext))
        {
            var context = new PrincipalContext(ContextType.Domain, "DOMAIN");

            UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(context, httpContext.User.Identity.Name);

            if (userPrincipal != null)
            {
                PrincipalSearchResult<Principal> groups = userPrincipal.GetGroups();

                bool found = groups.Any(item => item.Name == "NAME OF GROUP HERE");

                if (found)
                {
                    return false;
                }
            }

            return true;
        }
        return false;
    }

    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {
        filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary
            {
                {"action", "AccessDenied"},
                {"controller", "Error"}
            });

    }

我在 global.asax 中添加了上述内容并添加到过滤器中。

 public static void RegisterGlobalFilters(GlobalFilterCollection filters)
 {
    filters.Add(new AuthorizeADAtttribute());           
 }

希望有人可以帮助我。

谢谢
