下面代码可实现记录返回登录页时的地址，时时验证登录信息

(由软谋eleven老师提供)

/// <summary>
        /// ajax跟exception一致
        /// 检验登陆和权限的filter
        /// </summary>
        [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true)]
        public class AuthorityFilter : AuthorizeAttribute
        {
            /// <summary>
            /// 未登录时返还的地址
            /// </summary>
            private string _LoginPath = "";
            public AuthorityFilter()
            {
                this._LoginPath = "/User/Login/Login";
            }
    
            public AuthorityFilter(string loginPath)
            {
                this._LoginPath = loginPath;
            }
    
            public override void OnAuthorization(AuthorizationContext filterContext)
            {
                if(filterContext.ActionDescriptor.IsDefined(typeof(AllowAnonymousAttribute),true)
                    || filterContext.ActionDescriptor.ControllerDescriptor.IsDefined(typeof(AllowAnonymousAttribute),true))
                {
                    return;//表示支持控制器、action的AllowAnonymousAttribute
                }
    
                var sessionUser = HttpContext.Current.Session["CurrentUser"];//使用session
                //var memberValidation = HttpContext.Current.Request.Cookies.Get("CurrentUser");//使用cookie
    
                //验证session是否正确
                if (sessionUser == null || !(sessionUser is CurrentUser))
                {
                    HttpContext.Current.Session["CurrentUrl"] = filterContext.RequestContext.HttpContext.Request.RawUrl;
                    filterContext.Result = new RedirectResult(this._LoginPath);
                }
    
            }
        }
