c# - Nancy.TinyIoc.TinyIoCResolutionException: タイプを解決できません

Question

dotnet コアで Nancy を使用して動作する JWT でステートレス認証を取得しようとしています。これをUbuntu VMで実行しています。しかし、私は私のでcannot resolve typeエラーに遭遇Startup.csし続けますx.UseNancy();

私のスタートアップクラスは次のようになります。

public class Startup
{
   public static IConfigurationRoot Configuration;



   public Startup(IHostingEnvironment env)
   {
        Configuration = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json")
            .AddEnvironmentVariables()
            .Build();
   }

    public void Configure(IApplicationBuilder app)
    {
        app.UseOwin(x =>
        {
            x.RequiresStatelessAuth(
                new MySecureTokenValidator(new ConfigProvider(Configuration)),
                new StatelessAuthOptions() { IgnorePaths = new List<string>(new[] { "/login", "/content" }) });
            x.UseNancy();
        });
    }
}

私の ConfigProvider クラス:

public class ConfigProvider : IConfigProvider
{
    private readonly IConfigurationRoot config;

    public ConfigProvider(IConfigurationRoot config)
    {
        this.config = config;
    }

    public string GetAppSetting(string propertyName)
    {
        return config.GetSection($"AppSettings:{propertyName}").ToString();
    }
}

RequiresStatelessAuth 拡張機能:

using MidFunc = System.Func<System.Func<System.Collections.Generic.IDictionary<string, object>,
    System.Threading.Tasks.Task>, System.Func<System.Collections.Generic.IDictionary<string, object>,
    System.Threading.Tasks.Task>>;

public static class StatelessAuthExtensions
{
    public static Action<MidFunc> RequiresStatelessAuth(this Action<MidFunc> builder, ITokenValidator tokenValidator, StatelessAuthOptions options = null)
    {
         builder(next => new StatelessAuth(next, tokenValidator, options).Invoke);
         return builder;
    }
}

ホームモジュール:

public class HomeModule : NancyModule
{
    public HomeModule(IConfigProvider configProvider, IJwtWrapper jwtWrapper)
    {
        //some code here
    }
}

IoC コンテナーに何も登録していません。しかし、ブートストラップで以下を試しました：

protected override void ConfigureApplicationContainer(TinyIoCContainer container)
{
    base.ConfigureApplicationContainer(container);
    container.Register<IConfigProvider, ConfigProvider>();
    container.Register<ConfigurationRoot>();
}

それが機能するために、アプリケーション全体に変更IConfigurationRootしました。ConfigurationRoot

何を試しても同じエラーが発生します。スタックトレース：

私は Nancy/Linux/dotnet コア初心者ですが、この問題を解決する方法を誰か説明してもらえますか?

編集、作業コード:

ブートストラップの変更:

public class CustomBootstrapper : DefaultNancyBootstrapper
{
    private ConfigurationRoot config;

    public CustomBootstrapper(ConfigurationRoot config)
    {
        this.config = config;
    }

    protected override void ConfigureApplicationContainer(TinyIoCContainer container)
    {
        base.ConfigureApplicationContainer(container);
        container.Register<ConfigurationRoot>(config);
    }

    //more code
}

Startup.cs:

public void Configure(IApplicationBuilder app)
{
    app.UseOwin(x =>
    {
        x.RequiresStatelessAuth(
            new MySecureTokenValidator(new ConfigProvider((ConfigurationRoot)Configuration)),
            new StatelessAuthOptions() { IgnorePaths = new List<string>(new[] { "/login", "/content" }) });
        x.UseNancy(opts => opts.Bootstrapper = new CustomBootstrapper((ConfigurationRoot)Configuration));
    });
}

サイト ノート: おそらくを be of typeに変更Configurationし、上記のように 2 回ではなく、-のコンストラクターで 1 回だけ型キャストを行います。Startup.csConfigurationRootStartup.csConfigure
