How to get current base url in register route class?

Question

I'm developing plugin for nopcommerce shopping cart(ASP.NET Core 2.1). Before registering routes in RouteProvider class,i need to access current domain name in order to some validation checks but when using IHttpContextAccessor to get Httpcontext and get current domain, Httpcontext is null.

Is there any solution to access current domain name in route provider class?

 public void RegisterRoutes(IRouteBuilder routes)
 {
    var httpContextAccessor = EngineContext.Current.Resolve<IHttpContextAccessor>();
    var domainName = httpContextAccessor.HttpContext.Request.Host.Value.ToString();

    var pluginValidtyChecker = new PluginValidityChecker.ValidityChecker();
    if (pluginValidtyChecker.CheckIsValid(domainName))
    {

     //Register routes

    }
 }

In the application developed by me users first enter the domain name the plugin should work on and then buy plugin.After purchasing we generate a license key that's mapped with domain name and users must be entered this license key in plugin settings. Because plugin override some main route of nopcommerce i need first check that license key and domain name that's plugin currently work on, is valid or not. This route must be registered on compile time.

It’s not easy to ensure, that the domain name is always available, because it’s up to the programmers to define it either in a configuration-file, or as Environment-Variable.

Furthermore, if the application runs in an AWS-container, the configuration is a bit more complicated, because the configuration-file has a different structure. There is an Nuget-Package available the easy up things, but still not everybody uses it.

So what you want can’t be ensured in a bulletproof way.

If anybody can correct me. I would be quite happy, because I had a similar issue, which I could solve for my own application, but I‘m not glad with my solution yet.
