I'm trying to figure out how to call a service from an asp mvc4 controller, but I just can't. I already set up the services but when I'm trying to call from my controller method it displays this :

Here's my code:
Global.asax.cs
namespace mvc4_servicestack
{
// Nota: para obtener instrucciones sobre cómo habilitar el modo clásico de IIS6 o IIS7,
// visite http://go.microsoft.com/?LinkId=9394801
public class MvcApplication : System.Web.HttpApplication
{
public class AppHost : AppHostBase
{
public AppHost()
: base("Nombre del Host de los WebService", typeof(SS_WebServices.StatusService).Assembly)
{ }
public override void Configure(Funq.Container container)
{
}
}
protected void Application_Start()
{
new AppHost().Init();
AreaRegistration.RegisterAllAreas();
// WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
AuthConfig.RegisterAuth();
}
}
}
namespace mvc4_servicestack { public class SS_WebServices {
//Request DTO Objet
[ServiceStack.ServiceHost.Route("/Home/About/statuss")]
[ServiceStack.ServiceHost.Route("/Home/About/statuss/{Name}")]
public class StatusQuery : ServiceStack.ServiceHost.IReturn<StatusResponse>
{
public string Name { get; set; }
public int Id { get; set; }
}
//Response DTO Object
public class StatusResponse
{
public string Result { get; set; }
}
//Service
public class StatusService : ServiceStack.ServiceInterface.Service
{
//Implement teh Method VERB (POST,GET,PUT,DELETE) OR Any for ALL VERBS
public object Any(StatusQuery request)
{
//Looks strange when the name is null so we replace with a generic name.
var name = request.Name ?? "John Doe";
return new StatusResponse { Result = "Hello, " + name };
}
}
}
}
I've been reading the post Should ServiceStack be the service layer in an MVC application or should it call the service layer?
But Still I can't understand things like : WHY Register returns an Interface instead a GreeterResponse? container.Register(c => new Greeter());
I really hope you guys can help me...!
Since ServiceStack is hosted in the same AppDomain as MVC, you don't need to use a ServiceClient and go through HTTP to access ServiceStack Services, instead you can just resolve and call the Service normally, E.g:
public HelloController : ServiceStackController
{
public void Index(string name)
{
using (var svc = base.ResolveService<HelloService>())
{
ViewBag.GreetResult = svc.Get(name).Result;
return View();
}
}
}
Outside of a Controller a ServiceStack Service can be resolved via
HostContext.ResolveService<T>()
See the MVC Integration docs for more info.
But Still I can't understand things like : WHY Register returns an Interface instead a GreeterResponse? container.Register(c => new Greeter());
Greeter is just a normal C# dependency (i.e. it's not a ServiceStack Service). The container isn't returning IGreeter here, instead it's saying to "Register the Greeter implemenation against the IGreeter interface":
container.Register<IGreeter>(c => new Greeter());
If you registered it without, it will just be registered against the concrete type, e.g. these are both equivalent:
container.Register(c => new Greeter());
container.Register<Greeter>(c => new Greeter());
Which means you would need to specify the concrete dependency to get it auto-wired, e.g:
public class MyService : Service
{
public Greeter Greeter { get; set; }
}
Instead of being able to use:
public IGreeter Greeter { get; set; }
Which is much easier to test given that it's a mockable interface.
