将Web Api MapHttpRoute映射到基本网址

Question

Hi I have a Controller as shown below,

[RoutePrefix("")]
public class ApiInformationController : Controller
{
    public ActionResult Index()
    {
        var info = new ApplicationInformation
        {
            ApplicationName = "Test App",
            DatabaseName = "SQL Server 2012",
            ApplicationVersion = "3.10.0"
        };
        return Json(info, JsonRequestBehavior.AllowGet);
    }
}

I also configured the routes in WebApiConfig as I do not want to use RouteConfig separately,

private static void ConfigureRoutes(HttpConfiguration config)
    {
        _config = config;

        // Web API routes
        _config.MapHttpAttributeRoutes();

        _config.Routes.MapHttpRoute("Default", "{controller}/{action}/{id}",
            new {controller = "ApiInformation", action = "Index", id = RouteParameter.Optional});
        _config.Routes.MapHttpRoute(name: "DefaultApi", routeTemplate: "api/{controller}/{id}",
            defaults: new {id = RouteParameter.Optional});
    }

When I try and access the base url, I want the ApiInformation to be displayed. For Example when I try http://localhost:23175/ I would like the Api to call the Index of ApiInformationController. What am I doing wrong here?

Current when I call the url I am getting the following response,

Need to modify MapHttpRoute's routeTemplate.

WebApiConfig like,

config.Routes.MapHttpRoute("Default", "{controller}/{action}/{id}",
        new { controller = "ApiInformation", action = "Index", id = RouteParameter.Optional });

And how you receive,

[System.Web.Http.HttpGet]
public IHttpActionResult Index()
{
    var info = new ApplicationInformation
    {
        ApplicationName = "Test App",
        DatabaseName = "SQL Server 2012",
        ApplicationVersion = "3.10.0"
    };
    return Json(info);
}

Hope it will help you
