使用ASP.Net Core的NancyFX中的静态内容

Question

I'm using Nancy 2.0.0 with ASP.Net Core 2.0.0 and I can't get my application to return static content (in this case, a zip file) from a route defined in a Nancy module.

The Nancy convention is to store static content in /Content and the ASP.Net Core convention is to store it in /wwwroot , but I can't get my app to recognize either.

My Startup.Configure method looks like this:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseStaticFiles();            
    app.UseOwin(b => b.UseNancy());
}

And my module route looks like this:

Get("/big_file", _ => {
    return Response.AsFile("wwwroot/test.zip");
});

But Nancy always returns a 404 when I hit this route. I've also tried directing ASP.Net Core to the static directory expected by Nancy, like this:

app.UseStaticFiles(new StaticFileOptions()
{
    FileProvider = new PhysicalFileProvider(Path.Combine(Directory.GetCurrentDirectory(), @"Content")),
    RequestPath = new PathString("/Content")
});

But this didn't work either. I've tried putting the file in /Content and in /wwwroot with the same result. And I've tried different casing of Content , but nothing seems to work. What am I missing?

I figured it out. The issue was that I needed to let Nancy know what I wanted to use as the root path for the application. I did this by creating a class that inherits from IRootPathProvider . Nancy will discover any class that inherits from this on Startup, so you can put it wherever you want.

public class DemoRootPathProvider : IRootPathProvider
{
  public string GetRootPath()
  {
    return Directory.GetCurrentDirectory();
  }
}

Once this was in place I was able to access static content in /Content . Additionally, I was able to add additional static directories (for example, if I wanted to stick with /wwwroot ) by adding a class that inherits from DefaultNancyBootstrapper . Again, Nancy will find this on Startup, so you can put it anywhere.

public class DemoBootstrapper : DefaultNancyBootstrapper
{
  protected override void ConfigureConventions(NancyConventions conventions)
  {
    base.ConfigureConventions(conventions);

    conventions.StaticContentsConventions.Add(
        StaticContentConventionBuilder.AddDirectory("wwwroot")
    );
  }
}
