MVC 4: Custom Route | 易学教程

问题

ASP.NET MVC 4 website.

Got a database-table named "Locations", which holds only three possible Locations (eg. "CA","NY","AT") The default route would be:

http://server/Location/  --- list of Locations
http://server/Location/NY --- details of NY-Location

How can I create a custom route without the /Location/ - bit? (which I find a bit more nice)

So that

http://server/NY - details of NY
http://server/AT - details of AT
.... etc...

and

http://server/Location  --- list of Locations

回答1:

A solution is to do a custom route using a route constraint: (the order matters)

routes.MapRoute(
    name: "City",
    url: "{city}",
    constraints: new { city = @"\w{2}" },
    defaults: new { controller = "Location", action = "Details", id = UrlParameter.Optional }
);

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

with the matching controller:

public class LocationController : Controller
{
    //
    // GET: /Location/
    public ActionResult Index()
    {
        return View();
    }

    //
    // GET: /{city}
    public ActionResult Details(string city)
    {
        return View(model:city);
    }
}

If you want to allow only NY, CA and AT you could write you route constraint like:

constraints: new { city = @"NY|CA|AT" }

(lower case works too). Another, more generic solution instead of using a route contraint is to implement your own IRouteConstraint. Se my previous answer.

What you need is to specify the route inside your controller. Look at this tutorial on how to specify route constraints:

http://www.asp.net/mvc/tutorials/controllers-and-routing/creating-a-route-constraint-cs

You use route constraints to restrict the browser requests that match a particular route. You can use a regular expression to specify a route constraint.
