Construct url in view for Web Api with attribute routing

Question

How can I get the url from web api in my view?

Example (from the msdn-blog):

[RoutePrefix(\"reviews\")]
public class ReviewsController : ApiControlle         


        

Answer 1

Generating links to Web API routes always require a RouteName, so you should have something like below:

[Route("{reviewId}/edit", Name="EditView")]
public IHttpActionResult Edit(int reviewId) { ... }

You can then generate a link like /reviews/1/editto Web API.

Url.RouteUrl(routeName: "EditView", routeValues: new { httpRoute = true, reviewId = 1 });

or

Url.HttpRouteUrl(routeName: "EditView", routeValues: , reviewId = 1)

Note that route names need to be specified explicitly and they are no longer generated automatically like what @Karhgath is suggesting. This was a change made from RC to RTM version.

In WebApi2 when using AttributeRouting, route names are named by default Controller.Action, but you could specify a RouteName also:

[RoutePrefix("reviews")]
public class ReviewsController : Controller
{
    // The route name is defaulted to "Reviews.Index" 
    [Route]
    public ActionResult Index() { ... }

    // The route name is "ShowReviewById"
    [Route("{reviewId}"), RouteName("ShowReviewById")]
    public ActionResult Show(int reviewId) { ... }

    // The route name is by default "Reviews.Edit"
    [Route("{reviewId}/edit")]
    public ActionResult Edit(int reviewId) { ... }

Then to call it in the view you only need to set the route name and send the parameters as an anonymous object:

// Outputs: /reviews/123
@Url.Action("ShowReviewById", new { reviewId = 123 })
// Outputs: /reviews/123/edit
@Url.Action("Reviews.Edit", new { reviewId = 123 })

When using route attributes I was able to get the route of a WebApi2 controller from an MVC view using something like this:

Url.HttpRouteUrl("RouteName", new { })
