Using structureMap sample package in web application

Question

I use both of MVC and WebApi in my application. For implementing IoC i use structure map sample package(StructureMap.WebApi2)

In MVC controllers everything is ok but when i use web api, for example post something to server i get this error:

[HttpException]: The controller for path &#39;/api/Activity/AddActivity&#39; was not found or does not implement IController.
   at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType)
   at System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory)
   at System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, Object state)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step)
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

This is AddActivity action:

[HttpPost]
[ActionName("AddActivity")]
public HttpResponseMessage AddActivity(ActivityDTO activityDTO)
  {
      ActivityDTO data = activityDTO;
      HttpResponseMessage response = new HttpResponseMessage();

      data.UserID = User.Identity.GetUserId();

      int id = _activityServices.Add(data);

      if (id != -1)
      {
         response = this.Request.CreateResponse(HttpStatusCode.OK, id);
      }
      else
      {
         response=this.Request.CreateErrorResponse(HttpStatusCode.InternalServerError, "Activity doesn't save.");
      }

       return response;
  }

I check the path of action and it's correct.

can you help me?

thanks

UPDATE 1:

WebApiConfig.cs

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {

        var container = IoCFactory.Container;

        GlobalConfiguration.Configuration.Services.Replace(
            typeof(IHttpControllerActivator), new IoCWebApiControllerFactory(container));

        config.MapHttpAttributeRoutes();

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

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

AjaxRequest:

$.post("/api/Activity/AddActivity", data)

Have you tried this method: dotnettips.info/courses/topic/5/… — VahidN

Your issue is not the dependency injection. Put a break-point on the constructor and check if the injected dependencies are not null. If those are not null, your setup is correct.

You have routing issues. When you are using [ActionName("AddActivity")] you should have a routing defined like this:

routes.MapHttpRoute(
   name: "ActionApi",
   routeTemplate: "api/{controller}/{action}/{id}",
   defaults: new { id = RouteParameter.Optional } );

The default routeTemplate of web-api doesn't have the {action} part. Also you shouldn't use ActionName here, because it has a different purpose. Replace it with the Route attribute to use the attribute routing capabilities. More info

When you are using attribute routing your "/api" won't be used anymore. Start learning about attribute routing here dotnettips.info/post/1660
