ASP.NET API méthode de reliure Web

Question

J'ai deux méthodes comme celle-ci

public class ProductController : ApiController
{
    public Product GetProductById(int id)
    {
        var product = ... //get product
        return product;
    }

    public Product GetProduct(int id)
    {
        var product = ... //get product
        return product;
    }
}

Quand je url appelle: GET http: // localhost / api / produit / 1 . Je veux la première méthode est invoquée, pas la seconde méthode.
Comment puis-je faire?

Answer 1

You need unique URIs. You can modify your route to get this:

routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{action}/{id}",
        defaults: new { id = RouteParameter.Optional }

);

Now you can access your API like this:

http://localhost/api/product/GetProductById/1

http://localhost/api/product/GetProduct/1

I've written a little introduction to ASP.NET Web API which shows some of the differences to WCF Web API.

You can also add a default action, e.g. the one the lists all products so you can do something like this:

http://localhost/api/product/  // returns the list without specifying the method

and the other one is invoked this way

http://localhost/api/product/byid/1  // returns the list without specifying the method

What I do is having a ProductsController and a ProductController. ProductsController is responsible for operations on Collections of T (get all) and ProductController is responsible for operations on T (like getting a specific one).
