Requested document not found when using MVC routes

Question

I am getting 404s (requested document not found) when I try to use a custom route I created per the guide here: https://kb.sitecore.net/articles/700677. My patch config is showing up in showconfig, here's what it looks like:

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <pipelines>
      <initialize>
        <processor type="[obfuscated].Pipelines.Routes.RegisterCustomRoute, [obfuscated]" patch:before="processor[@type='Sitecore.Mvc.Pipelines.Loader.InitializeRoutes, Sitecore.Mvc']" />
      </initialize>
    </pipelines>
  </sitecore>
</configuration>

The processor code:

namespace BrightHorizons.Pipelines.Routes

{
    public class RegisterCustomRoute
    {
        public virtual void Process(PipelineArgs args)
        {
            RouteTable.Routes.MapRoute("CustomRoute", "api/{controller}/{action}/{id}");
        }
    }
}

The controller action and controller name seem correct... here's what that looks like:

public class FindACenterController : GlassController
{
    public ActionResult FindACenterMap()
    {
        ...
    }
}

I am trying to access it like this: http://mysite/api/FindACenter/FindACenterMap

I also tried using a basic Default route in the RouteConfig.cs (/{controller}/{action}/{id}) under App_Start before that and it did not work either. I am really not good at MVC routing so looking for some guidance.

UPDATE: FindACenterMap is now working, however this is not working for a different controller. Added a new route:

RouteTable.Routes.MapRoute("SubmitScheduleVisit",
    "api/SubmitScheduleVisit",
    new { controller = "FindACenter", action = "SubmitScheduleVisit" },
    new { httpMethod = new HttpMethodConstraint("POST") }
);

It's in the same controller. This is the action definition:

[HttpPost]
public ActionResult SubmitScheduleVisit(string selectedDate, string selectedTime, string firstName, string lastName,
            string emailAddress, string phoneNumber, string whenToStart, List<string> childDatesOfBirth)
{
     ....
}

SOLUTION TO UPDATE (Not a solution to the original question): I simply had to run the query in Postman. I was testing the API call in Firefox which meant it was getting run as a GET, not a POST. Solved.

Answer 1

The code below is code I reuse constantly. The only caveat is that is the controller is in a different project/library than the route initialization code, strange thing happen. I always keep the controller and initialize code together.

Your url would now be http://mysite/api/FindACenterMap

Please see this answer while modification of the global.asax is not required. Global.asax Application_Start not hit after upgrade to Sitecore 8.2

The route

public virtual void Process(PipelineArgs args)
{
    RouteTable.Routes.MapRoute("FindACenterMap",
        "api/FindACenterMap",
        new { controller = "FindACenter", action = "FindACenterMap" },
        new { httpMethod = new HttpMethodConstraint("GET") }
    );

    RouteTable.Routes.MapRoute("SubmitScheduleVisit",
        "api/SubmitScheduleVisit",
        new { controller = "FindACenter", action = "SubmitScheduleVisit" },
        new { httpMethod = new HttpMethodConstraint("POST") }
    );
}

The controller

public class FindACenterController : GlassController
{
    [HttpGet]
    public ActionResult FindACenterMap()
    {
        ...
    }

    [HttpPost]
    public ActionResult SubmitScheduleVisit(string selectedDate, string selectedTime, string firstName, string lastName, string emailAddress, string phoneNumber, string whenToStart, List<string> childDatesOfBirth)
    {
            ....
    }
 }

The config

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <pipelines>
      <initialize>
        <processor type="[obfuscated].Pipelines.Routes.RegisterCustomRoute, [obfuscated]" patch:before="processor[@type='Sitecore.Mvc.Pipelines.Loader.InitializeRoutes, Sitecore.Mvc']" />
      </initialize>
    </pipelines>
  </sitecore>
</configuration>
