ASP.net Web API 2 custom methods

Question

I've added this method to my web api controller:

    [HttpPost]
    public bool CreateTrening(int routineId)
    {
        try
        {
            var userId = User.Identity.GetUserId();
            TreningService.CheckIfLastTrenigWasCompleted(userId);
            TreningService.CreateTreningForUser(userId, routineId);
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }
    }

And I've added another route to my WebApiConfig file, so it looks like this now:

       config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
           name: "CustomApi",
           routeTemplate: "{controller}/{action}/{id}",
           defaults: new { id = RouteParameter.Optional }
       );

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

But when I try to call my method:

/EditWorkout/CreateTrening/1

I get this error:

{"Message":"No HTTP resource was found that matches the request URI '/EditWorkout/CreateTrening/1'.","MessageDetail":"No action was found on the controller 'EditWorkout' that matches the request."}

How can I call my method which is in WebApi controller ?

Answer 1

Calling with that URL to a post method will not work because the post expects the values transmitted in the Http Message body. not in the URL so your controller is not finding the method.

Probably the best solution for this is to encode your posted value in the http message you send the controller, and call the URL with /EditWorkout/CreateTrening, this will work as a post.
