How to get RouteData.Values["action"].ToString() from User Attribute

Question

    [CheckAccessMethod(RouteData.Values["action"].ToString())]
    [HttpGet]
    public IActionResult Get(){...}

    class CheckAccessMethodAttribute : Attribute
    {
         string MethodName { get; set; }

        public  CheckAccessMethodAttribute(string methodName)
        {
            MethodName = methodName;
        }

    }

I can’t get the current request route. I want to create method access logic for users

One option would be to use the ActionFilterAttribute, then you'd have access to the ResultExecutingContext which has the route data you need. More information here

public class MyActionFilterAttribute : ActionFilterAttribute
{
     public override void OnResultExecuting(ResultExecutingContext context)
     {
         var action = context.RouteData.Values["action"];
         //do something with action here

         base.OnResultExecuting(context);
     }
 }
