How to combine pattern and attribute based routing in ASP.NET Core?

Question

I need to define pattern-based routing for the controller, and then an action-based attribute in ASP.NET Core. Sort of:

public class Foo : Controller
{
    [HttpGet]
    public object Get()
    {
        return new
        {
            ID = "A"
        };
    }

    [HttpPost]
    public object Create([FromBody]dynamic entity)
    {
        return new
        {
            ID = "B"
        };
    }


}

Route

app.UseMvc(routes =>
        {
            routes.MapRoute("Settings", "settings/api/foo",
                    new { controller = "Foo" }
            );
        });

And I expect this to work:

GET /settings/api/foo
POST /settings/api/foo

Unfortunately, this is not the case. It appears that route attributes are ignored. What is the best way to achieve the requirement?

The trick here is to direct the URL to a specific controller and action. Then use the action method overload with the action method switch to switch between GET and POST.

Change the route setup code to this:

app.UseMvc(routes =>
{
    routes.MapRoute(
        "Settings",
        "settings/api/foo",
        new {
            controller = "Foo", // specific controller
            action = "DoThing", // AND specific action
        }
    );
});

( - HTTP-) , :

public class FooController : Controller
{
    [HttpGet] // different action method selector!
    public object DoThing() // same name!
    {
        return new
        {
            ID = "A"
        };
    }

    [HttpPost] // different action method selector!
    public object DoThing([FromBody]dynamic entity) // same name!
    {
        return new
        {
            ID = "B"
        };
    }
}

MVC URL DoThing Foo. , : ", , , , !" [HttpGet] [HttpPost], , , , .
