Webapi 2 Route Configuration web form application

Question

About 6 months ago I am entering the MVC world, before I used a lot of Webforms and I confess that I have difficulties understanding how to configure the routes for a ApiController, from what I noticed I can’t have two identical queries (with the same parameters), but I’m a little embarrassed to set this up.

Below I will put an example of code that is giving the error below while trying to access them.

{  
   "Message":"No HTTP resource was found that matches the request URI 'http://localhost:54596/api/graficos/usuarios/'.",
   "MessageDetail":"No action was found on the controller 'Graficos' that matches the name 'usuarios'."
}

Graphiccontroller

public class GraficosController : ApiController
{

    [HttpGet]
    //[Route("api/graficos/usuarios/{action}/{param}")]
    public List<UsuarioDashboard> BuscaUsuarioDashboard(string param)
    {
        return Fachada.FachadaEstatisticas.BuscaUsuarioDashboard(param);
    }
    [HttpGet]
    //[Route("api/graficos/emails/{action}/{param}")]
    public List<EmailNaoEnviado> EmailsNaoEnviados(string data)
    {
        return Fachada.FachadaEstatisticas.EmailsNaoEnviados(Convert.ToDateTime(data));
    }

}

In the Global.asax I’m making the route as follows:

RouteTable.Routes.MapHttpRoute(
    name: "Site",
    routeTemplate: "api/{Controller}/{action}/{site}",
    defaults: new { }
);

 RouteTable.Routes.MapHttpRoute(
     name: "Usuarios",
     routeTemplate: "api/{controller}/{action}/{param}",
     defaults: new { }
 );

 RouteTable.Routes.MapHttpRoute(
     name: "Graficos",
     routeTemplate: "api/{controller}/{action}",
     defaults: new { }
 );

I think my mistake is trying to take advantage of the same controller for more than one function. That’s it?

I’ve searched a lot of sites, but I can’t find one that has an explanation that I understand.

Alex, first you do not need to register several routes in your Global.asax, s you need to customize a route using the attribute Route.

I know you’ve done most of the work below, but just in case I’ll start from the beginning.:

Create a class WebApiConfig inside App_Start:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

In the global.asax only register the routes:

protected void Application_Start()
{
    GlobalConfiguration.Configure(WebApiConfig.Register);          
}

now in your classes, do so:

[RoutePrefix("api/graficos")]
public class GraficosController : ApiController
{

    [HttpGet]
    [Route("BuscaUsuarioDashboard/{param}")]
    public List<UsuarioDashboard> BuscaUsuarioDashboard(string param)
    {
        return Fachada.FachadaEstatisticas.BuscaUsuarioDashboard(param);
    }

    [HttpGet]
    [Route("EmailsNaoEnviados/{data}")]
    public List<EmailNaoEnviado> EmailsNaoEnviados(string data)
    {
        return Fachada.FachadaEstatisticas.EmailsNaoEnviados(Convert.ToDateTime(data));
    }
}

now you can make the following calls:

GET: api/graficos/EmailsNaoEnviados/2016-01-01
GET: api/graficos/BuscaUsuarioDashboard/userName
