用原生的 Attribute 是达不到效果必须重写

public class LoginAuthorizationFilter : Attribute, IAuthorizationFilter
    {
        private readonly IHttpContextAccessor _httpContextAccessor;
        private ISession _session => _httpContextAccessor.HttpContext.Session;

        public AdminLoginAuthorizationFilter(IHttpContextAccessor httpContextAccessor)
        {
            _httpContextAccessor = httpContextAccessor;
        }
        public void OnAuthorization(AuthorizationFilterContext context)
        {
            //也可以这样获取Session，就不需要注入了。
            var testData = context.HttpContext.Request.Cookies.TryGetValue("User", out string value);
            if (!testData || string.IsNullOrWhiteSpace(value))
            {
                ContentResult Content = new ContentResult();
                Content.Content = "<script type='text/javascript'>parent.window.location.href='/User/Login'</script>";
                Content.ContentType = "text/html";
                //截断请求
                context.Result = Content;
            }
        }
    }

使用  [TypeFilter(typeof(LoginAuthorizationFilter))]
