can't figure out routing in asp.net mvc - asp.net-mvc

Question

I'm doing my first steps in asp.net mvc trying to develop web api.
I have the following routing function:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "cdApiDefault",
url: "api/{controller}/{action}/{token}/{mid}/{id}",
defaults: new {
token = UrlParameter.Optional,
mid = UrlParameter.Optional,
id = RouteParameter.Optional }
);
}
and the following controller:
namespace cdapi.Controllers
{
public class PostsController : ApiController
{
// GET api/posts
public IEnumerable<string> Get()
{
return new string[] { "GET_value1", "GET_value2" };
}
// GET api/posts/5
public string Get(int id)
{
return "value!!!!!!!!!!!!!!!!!";
}
// POST api/posts
public void Post([FromBody]string value)
{
}
// PUT api/posts/5
public void Put(int id, [FromBody]string value)
{
}
// DELETE api/posts/5
public void Delete(int id)
{
}
public String GetTest(String token, String mid)
{
return token + " - " + mid;
}
}
}
the following call
hxxp://localhost:52628/api/posts/5
(in my browser) yields some result, i.e., the function GET is being called and return a value.
However, when I try
hxxp://localhost:52628/api/posts/GetTest/MyTestToken/myTestMid
comes back with 'the resource can not be found' error message.
I thought that the {Action} should contain the function to call and that the 'token' and 'mid' should contain the values I specify. What do I do wrong?

ApiControllers work differently than regular MVC Controllers. Here, method names (GET, POST, PUT, DELETE) represent HTTP VERBS, not url fragment. In your first call,
/api/posts/5
this invokes Get(int).
To do routing like you want, switch to standard MVC by inheriting from System.Web.Mvc.Controller instead of System.Web.Http.ApiController and modify your methods to return ActionResult
