Question

I\'ve the following problem, my route attribute is not working.

I have the following action:

[HttpGet]
[Route(\"~api/admin/template/{fileName}\")]
pu         


        

Answer 1

In my case, I added Route("api/dashboard") to api controller. Changed it to RoutePrefix("api/dashboard") . And it works perfectly. Also you need config.MapHttpAttributeRoutes(); in webapiconfig.cs

Answer 2

With my Web API 2 project I had to add a [RoutePrefix("events")] to the controller for it to pickup the action route attribute.

Answer 3

You have to call MapHttpAttributeRoutes() so that the Framework will be able to walk through your attributes and register the appropriate routes upon application start:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

        // you can add manual routes as well
        //config.Routes.MapHttpRoute(...
    }
}

See MSDN

Answer 4

try adding a forward slash after the tilde
[HttpGet]
[Route("~/api/admin/template/{fileName}")]
public HttpResponseMessage Template(string fileName)
{
    return CreateHtmlResponse(fileName);
}

Answer 5

Check your Route attribute's namespace. It should be System.Web.Http instead of System.Web.Mvc.

Answer 6

Try this routing in your WebApiConfig

        // Web API routes
        config.MapHttpAttributeRoutes();

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

You have to add RoutePrefix.
