我的代码如下：

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method,AllowMultiple = false,Inherited = false)]
    public class CustomAuthorization : AuthorizationFilterAttribute
    {
        public override void OnAuthorization(AuthorizationContext context)
        {
            //// Attempt 1 - 404 error.  
            //// Doesnt block method with this attribute from executing (not desired behavIoUr).

            //context.HttpContext.Response.StatusCode = 401;
            //return; 

            //// Attempt 2 - 404 result. 
            //// Code with attribute doesnt execute (desired).
            //// Error thrown says:  An exception of type 'System.Web.Http.HttpResponseException' occurred in <namespace> but was not handled in user code
            //// Additional information: Processing of the HTTP request resulted in an exception. Please see the HTTP response returned by the 'Response' property of this exception for details.

            //throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.Unauthorized));

            // Attempt 3 - 404 result. 
            // Code with attribute doesnt execute (desired).
            context.Result = new HttpUnauthorizedResult();
        }
    }

我遇到的问题是我从网络API而不是预期的401获得404响应.我做错了什么？

这是asp.net核心1.
