AbpWebApi and DynamicApiControllerBuilder and MapHttpAttributeRoutes only exist in the net framework mvc. if you are using the net core there are relevant documents:[http://aspnetboilerplate.com/Pages/Documents/AspNet-Core#controllers])
But MapHttpAttributeRoutes does not achieve your purpose. As i know currently ABP's dynamic API has not been able to customize routes.
If you click [Download Test Project], the test project will be downloaded. But if your ProjectName does not contain a Test string, the download will automatically add a Test string to your project name.
As far as I know, dynamic api has no custom routing features for the time being. If you want to use url to pass parameters, you can change the parameters of the application layer method from object to multiple simple parameters.
Such as:
Task Create(CreateInput input); Task Create(string name, int age);
