ASP.NET Web API - Routing

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?

Answer 1

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.

You need:

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

You'll probably still need the ActionName attribute (but I'm not sure) and you might want to remove the RouteParameter.Optional default from the action unless you want to also have Get requests for (e.g):

api/clients/4 

serviced by a Get action in your controller.
