OWIN中的Nancy和WebAPI自托管路由冲突

Question

I'm doing some work with OWIN for the first time and am trying to set things up so that I can leverage Web API with attributed routing for backend services and I'd like to use Nancy as a simple file server to serve up my angular SPA code.

My OWIN startup code:

public class Startup : IOwinAppBuilder
{
    public void Configuration(IAppBuilder appBuilder)
    {
        var config = new HttpConfiguration();

        config.MapHttpAttributeRoutes();
        //FormatterConfig.ConfigureFormatters(config.Formatters);

        config.Formatters.Clear();
        config.Formatters.Add(new JsonMediaTypeFormatter());
        config.Formatters.JsonFormatter.SerializerSettings =
        new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver()
        };

        //appBuilder.UseNancy();
        appBuilder.UseWebApi(config);
    }
}

I have a Test controller set up with some endpoints appropriately decorated for attribute routing. At this point running the app and attempting to hit one of those endpoints returns the expected results.

I then tried to add Nancy to the equation. I added a single Nancy Module with the intention that it would serve up the angular content:

public class HomeModule : NancyModule
{
    public HomeModule()
    {
        Get["/"] = _ => View["home"];
    }
}

Uncommenting the appBuilder.UseNancy() line in the Startup and running the server works perfect to get the home view. However, now when I attempt to hit one of the API endpoints, Nancy seems to be kicking in and handling the request and returning me a 404 page instead of the API result. Is there a way to make Nancy and Web API play nicely together such that their routes will not conflict like this?

Did you test the PerformPassThrough or PassThroughWhenStatusCodesAre in UseNancy() method?

It is documented in Conditional pass-through section of Hosting nancy with owin. ( https://github.com/NancyFx/Nancy/wiki/Hosting-nancy-with-owin#conditional-pass-through )
