为什么带有ASP.NET MVC5路由属性的友好url每次都不起作用？

Question

I want to know why a friendly URL is generated from one action and not on the other.

Let's me show you!

    [RoutePrefix("fr-ca/guest")]
    public class GuestController : BaseController
    {        
        [Route("users/{id:int}/{ids:int}")]
        public ActionResult Index(int id, int ids)
        {
            return View();
        }

        [Route("register/{id:int}/{ids:int}")]
        public ActionResult Register(int id, int ids)
        {
            return View();
        }
    }

To get the friendly URL results, I use Razor like this:

@Html.ActionLink("some text", "Index", "Guest", new { id = 1, ids = 1 }, null)
@Html.ActionLink("some other text", "Register", "Guest", new { id = 1, ids = 1 }, null)

And in the route config file I added this line: routes.MapMvcAttributeRoutes();

So the first on work properly, I get the http:.../fr-ca/guest/users/1/1 But the second one doesn't work! I get http:.../fr-ca/guest/register?id=1&ids=1

Anyone can help?

Thank you!!

Answer 1

Assuming you do not have any other route definition which is conflicting with this,

@Html.ActionLink("some other text", "Register", "Guest", new { id = 1, ids = 1 }, null) will generate anchor tag with href value as http://yoursitename/fr-ca/guest/register/1/1 , not http:.../fr-ca/guest/register?id=1&ids=1

Since you have specified the pattern as register/{id:int}/{ids:int} It should work fine for register/1/1 url, but not for /register?id=1&ids=2 . That is the expected behavior.

Answer 2

Instead of using Html.ActionLink you can use Html.RouteLink . This helper has an overload that takes the name of a route to be used. You must add a name to your route though:

In your controller:

[Route("register/{id:int}/{ids:int}", Name="GuestRegister")]
public ActionResult Register(int id, int ids)
{
    return View();        
}

In your view:

@Html.RouteLink("some other text", "GuestRegister", new { id = 1, ids = 1 }, null)

This results in:

http://.../fr-ca/guest/register/1/1
