无法访问OnActionExecuting下的User.Identity(ActionExecutingContext filterContext)

Question

我不知道我错过了什么,但我真的不能参考 User.Identity下OnActionExecuting(ActionExecutingContext filterContext)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
using System.Web.Routing;

.....

    public class RealUserAttribute : ActionFilterAttribute
    {
            public override void OnActionExecuting(ActionExecutingContext filterContext)
            {
                 /// if (User.Identity.IsAuthenticated)

有任何线索如何修复它？

Answer 1

我找到了解决方案.

它应该是

filterContext.HttpContext.User.Identity.IsAuthenticated

Answer 2

我相信您应该使用AuthorizeAtribute而不是ActionFilter.尝试这样的事情:

using System.Web;
using System.Web.Mvc;

public class AuthorizeUser : AuthorizeAttribute
{
    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        var id = filterContext.RequestContext.HttpContext.User.Identity;
    }
}
