WebAPI No action was found on the controller - asp.net

Question

I got an error - No action was found on the controller 'Action' that matches the request.
The url is http://localhost:37331/api/action/FindByModule/1.
The routing I used is
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
Controller:
public class ActionController : ApiController
{
private IActionRepository repository = null;
[HttpGet]
[ActionName("All")]
public IEnumerable<JsonAction> All()
{
return from action in this.repository.Get()
select new JsonAction
{
ID = action.ID,
Text = action.Text.Trim(),
Description = action.Description.Trim(),
};
}
[HttpGet]
[ActionName("FindByModule")]
public IEnumerable<JsonAction> FindByModule(Int64 moduleId)
{
return from action in this.repository.FindByModule(moduleId)
select new JsonAction
{
ID = action.ID,
Text = action.Text.Trim(),
Description = action.Description.Trim(),
};
}
}

Answer 1

This is because there is a parameter name mismatch. From your route the value 1 is assigned to parameter named id and your action is looking for parameter named moduleId.
First option is to change your route like this:
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{moduleId}",
defaults: new { moduleId = RouteParameter.Optional }
);
Second is to change your URL like this:
http://localhost:37331/api/action/FindByModule?moduleId=1
So the parameter name match.

My api had too many parameters and I was getting an error. I solved the problem with Route.
[Route("addressverification/{id}/{no}/{day}/{month}/{year}")]
public AdressVerificationResult Get(long? id, long? no ,long? day, long? month, long? year)
{
return new AdressVerificationResult
{
Aciklama = "19........4 kimlik numaralı kişinin 18.......1 adres numarasında 'YerlesimYeri' adres tipi için geçerli bir yurtiçi adres beyanı mevcuttur.",
DurumKod = true
};
}
