Controller and Action from Global Error Handler - asp.net-core

Question

I'm migrating an web api from .Net to .NetCore.
We had a custom ExceptionFilterAttribute to handle errors in a centralized way. Something like this:
public class HandleCustomErrorAttribute : ExceptionFilterAttribute
{
public override void OnException(HttpActionExecutedContext filterContext)
{
// Error handling routine
}
}
With some search, I managed to create something similar on .Net Core
public static class ExceptionMiddlewareExtensions
{
public static void ConfigureExceptionHandler(this IApplicationBuilder app)
{
app.UseExceptionHandler(appError =>
{
appError.Run(async context =>
{
context.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
context.Response.ContentType = "application/json";
var contextFeature = context.Features.Get<IExceptionHandlerFeature>();
if (contextFeature != null)
{
//logger.LogError($"Something went wrong: {contextFeature.Error}");
await context.Response.WriteAsync(new ErrorDetails()
{
StatusCode = context.Response.StatusCode,
Message = "Internal Server Error."
}.ToString());
}
});
});
}
}
I need to find a way to access these 3 info that where avaiable in .Net in .Net Core version:
filterContext.ActionContext.ActionDescriptor.ActionName;
filterContext.ActionContext.ControllerContext.ControllerDescriptor.ControllerName;
HttpContext.Current.Request.Url.ToString();
Is it possible ?

For a complete solution with registering ExceptionFilter and get request path, you could try like
ExceptinoFilter
public class ExceptinoFilter : IExceptionFilter
{
public void OnException(ExceptionContext context)
{
string controllerName = context.RouteData.Values["controller"].ToString();
string actionName = context.RouteData.Values["action"].ToString();
var request = context.HttpContext.Request;
var requestUrl = request.Scheme + "://" + request.Host + request.Path;
}
}
Register
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews(options => {
options.Filters.Add(new ExceptinoFilter());
});
}
