Custom Authorization Attribute with dependency injection

Custom Authorization attribute with Dependency resolved using HttpContext.

FOR SYNCHRONOUS

   public class CustomAuthFilter : AuthorizeAttribute, IAuthorizationFilter
    {

        public CustomAuthFilter(params string[] args)
        {
            Args = args;
        }

        public string[] Args { get; }

        public void OnAuthorization(AuthorizationFilterContext context)
        {
            int x = this.Args.Length;
            var service = context.HttpContext.RequestServices.GetRequiredService<ISample>();
            string name = service.GetName();
            context.Result = new UnauthorizedResult();
        }
    }

Controller 

 [CustomAuthFilter("Anish","jiya","sample")]
        public async Task<IActionResult> Index()
        {
            ViewBag.Title = "Organizer - Conference Overview";
            return View(await repo.GetAll());

        }

FOR ASYNC

public class CustomAuthFilter : AuthorizeAttribute, IAsyncAuthorizationFilter

    {

        public CustomAuthFilter(params string[] args)

        {

            Args = args;

        }

        public string[] Args { get; }

        public async Task OnAuthorizationAsync(AuthorizationFilterContext context)

        {

            //DO Whatever...

            //Resolve Services from the container

            var service = context.HttpContext.RequestServices.GetRequiredService<ISample>();

            var httpClientFactory = context.HttpContext.RequestServices.GetRequiredService<IHttpClientFactory>();

            string name = service.GetName();

            using var httpClient = httpClientFactory.CreateClient();

            var resp = await httpClient.GetAsync("https://jsonplaceholder.typicode.com/todos/1");

            var data = await resp.Content.ReadAsStringAsync();

            //Return based on logic

            context.Result = new UnauthorizedResult();

        }
