ASP.NET Web Api 2获取ID

Question

I have an ApiController as such:

public class MessengerController : ApiController
{
    public IEnumerable<string> GetAllMessages()
    {
        // irrelevant code
    }

    public IHttpActionResult GetMessage(int index)
    {
        // irrelevant code
    }
}

I am trying to call my GetMessage function with the following url:

http://localhost:58050/api/messenger/1

But that always calls my GetAllMessages function instead. Am I missing something? Here is my WebApiConfig class, I haven't changed it from the pregenerated code:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();

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

为GetMessage命名参数id ，而不是index 。
