Question

I am using Web API to expose a bunch of services. I am having issue with some routes and need some help.

I have the default route defined:

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

With this route I can hit normal routes such as: ‘/api/clients/’ and ‘/api/clients/4’. I would like a GET that hits the following routes ‘api/clients/4/profiles’ and ‘api/clients/4/validations’.

I have tried the following routes without success:

config.Routes.MapHttpRoute(
    name: "ClientProfilesApi",
    routeTemplate: "api/{controller}/{clientid}/profiles",
    defaults: new { action = RouteParameter.Optional },
    constraints: new { controller = "clients" }
    );

 config.Routes.MapHttpRoute(
   name: "ClientValidationsApi",
       routeTemplate: "api/{controller}/{clientid}/validations",
       defaults: new { action = RouteParameter.Optional },
   constraints: new { controller = "clients" }
   );

I also tried using the ‘ActionName’ attribute as follows:

[HttpGet]
[ActionName("profiles")]
public IEnumerableResponseDto<ProfileLayoutDto> GetProfiles(Int64 clientId, [FromUri] IEnumerableRequestDto request)
{ .... }


[HttpGet]
[ActionName("profiles")]
public IEnumerableResponseDto<ValidationLayoutDto> GetValidations(Int64 clientId, [FromUri] IEnumerableRequestDto request)
{ .... }

What am I missing? Is it not possible to have multiple GETs in a controller?

For routes ‘api/clients/4/profiles’ and ‘api/clients/4/validations’, name the actions ‘profiles’ and ‘validations’ then use the following routes BEFORE the default route:

config.Routes.MapHttpRoute(
    name: "ClientProfilesApi",
    routeTemplate: "api/clients/{clientid}/profiles",
    defaults: new { controller = "clients", action = "profiles",  },
    constraints: new {clientid = @"\d+" }
    );

 config.Routes.MapHttpRoute(
    name: "ClientValidationsApi",
    routeTemplate: "api/clients/{clientid}/validations",
    defaults: new { controller = "clients", action = "validations",  },
    constraints: new {clientid = @"\d+" }       );

This means route ‘api/clients/4/profiles’ goes to controller ‘clients’ and action ‘ profiles’ and that the parameter ‘clientid’ has to be an integer.

The default routes should ALWAYS be last.
