Aha if I navigate to the original URL and not the routePrefix'ed it is reached.

Is this expected behavior? That umbraco now ignores RoutePrefix / Route .net attributes?

Hello Marc,

Thank you for your response.

Doing the above, however, results in the following error:

"The object has not yet been initialized. Ensure that HttpConfiguration.EnsureInitialized() is called in the application's startup code after all other initialization code."

Hmm, that's what I added to make my UmbracoAuthorizedApiController route attributes to work...

what does your ApiController look like? and what are the routes you are trying to map?

When I'm referring to ApiController i mean the one that is built in with .net Web Api, which is the one I want to inherit from in my controllers. Doing that gives me no connection to the controllers.

Everything do, however, seems to work if my Controller inherits from the UmbracoApiController and I call the full route from Postman like: "~/umbraco/api/umbracocontent/~", which means that it toally ignores the RoutePrefix and Route attributes.

Hi Christian

If I inherit from UmbracoApiController

eg

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using Umbraco.Web.WebApi;

namespace Umbraco8.Controllers
{
    //[RoutePrefix("umbraco/api/members")]
    public class MembershipApiController : UmbracoApiController
    {
        [HttpGet]
        [Route("fish/api/members")]
        public IEnumerable<string> GetAllMembers()
        {
            return new[] { "Table", "Chair", "Desk", "Computer", "Beer fridge" };
        }
        [HttpGet]
        public IEnumerable<string> GetAllMembers2()
        { 

            return new[] { "Table", "Chair", "Desk", "Computer", "Beer fridge" };
        }
    }
}

then I have success with a request to /fish/api/members

but also I have called

 GlobalConfiguration.Configuration.MapHttpAttributeRoutes();

in the IComponent, (without that the attributes do not work)

switching to inheriting from a plain ApiController also works!

so key difference seems to be that call to MapHttpAttributeRoutes() what I'm not sure is why that 'just works' for me, and not for yourself, I did see an issue on the issue tracker regarding order of Components, and in my V8 project I have lots of components and composers investigating different aspects, I'm not sure if that means by luck mine is being executed when GlobalConfiguration exists....

be interesting to see if you called

GlobalConfiguration.Configuration.EnsureInitialized();

before, whether that would make a difference?

Hey Marc,

Thank you for putting so much effort into this!

It do seems weird that it's working on your end, as I have tried what you propose. But I will look deeper into it tomorrow and then come back with the results.

Ps. calling GlobalConfiguration.Configuration.EnsureInitialized(); before MapHttpAttributeRoutes() didn't help either.

To be continued.

Hi Christian, Marc,

Following this thread with a interest.

@Christian

Maybe setting the runtime level on your composer can solve your issue ?

Hey Guys,

Dave thank you for joining in.

I have now tried adding the RuntimeLevel attribute but that didn't solve the problem, also I have tried adding the component as to your suggestion Marc, still to no avail.

I get the error: "The object has not yet been initialized. Ensure that HttpConfiguration.EnsureInitialized() is called in the application's startup code after all other initialization code."

I have tried calling GlobalConfiguration.Configuration.EnsureInitialized(); before the routemapping which didn't solve it either. :-/

Hi Christian,

Maybe you can post your code ? That may give us some more details we are missing now.

Dave

After grave digging through lots of old github posts on other products i finally seem to have found a solution on the initializer problem which in the end solves the first problem.

If one calls configuration.Initializer(configuration); After MapHttpAttributeRoutes();

It ensures that the configuration is initialized before handling any requests. Everything now works and I am able to call my controllers thorugh my route prefixes!

TL;DR for further references:

1. Create custom API routes composer as pr. Marcs posts.
2. Call GlobalConfiguration.Configuration.MapHttpAttributeRoutes(); in the Initialize method.
3. Call GlobalConfiguration.Configuration.Initializer(GlobalConfiguration.Configuration); right after.
4. You're now able to use route attributes in Umbraco 8 :-)

Thank you for your time guys!

I have changed my implementation to follow the tips given by Dave dM and can confirm that it removes the necessity for calling GlobalConfiguration.Configuration.Initializer(GlobalConfiguration.Configuration) :-)

cool, explains why mine worked, eg component just happened to be first!

Thanks everyone for figuring this out for us!

Small note:

if after applying Bjarn procedure for the JSON formatters you end up receiving XML responses - in some edge cases where the Accept header is not received - you might restore the default JSON serialization with this:

jsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));

Why? I have no clue - but I read it here and it worked for me.

I found out that all my struggle with this lied in the fact that the Route decoration per default refers to System.Web.Mvc.RouteAttribute in the Umbraco API controller.

Changing that to use System.Web.Http.RouteAttribute instead made it work "out of the box" as per Marc's first post, without configuring and tweaking further:

Output:

Thank you all for contributing with your solutions. Here is the full working Example, based on the inital question:

public class UmbracoComponents
{
    [RuntimeLevel(MinLevel = RuntimeLevel.Run)]
    public class MapHttpRoutesComposer : ComponentComposer<MapHttpRoutesComponent>
    {

    }
    public void Compose(Composition composition)
    {
        composition.Components().Insert<MapHttpRoutesComponent>();
    }
    public class MapHttpRoutesComponent : IComponent
    {
        // initialize: runs once when Umbraco starts
        public void Initialize()
        {
            GlobalConfiguration.Configuration.MapHttpAttributeRoutes();
            GlobalConfiguration.Configuration.Initializer(GlobalConfiguration.Configuration);
            GlobalConfiguration.Configuration.EnsureInitialized(); 

        }

        public void Terminate()
        {

        }
    }
}

is working on a reply...
