c# - Nancy.TinyIoc.TinyIoCResolutionException：无法解析类型

Question

我一直在尝试使用 JWT 在 dotnet 核心上使用 Nancy 获得无状态身份验证。我在 Ubuntu VM 上运行它。但我总是在我的 at中遇到cannot resolve type错误Startup.csx.UseNancy();

我的启动类如下所示：

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();
        });
    }
}

我的 ConfigProvider 类：

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 扩展：

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;
    }
}

家庭模块：

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

我没有向 IoC 容器注册任何内容。但我在我的引导程序中尝试了以下内容：

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

为此，我更改IConfigurationRoot为ConfigurationRoot跨应用程序。

无论我尝试过什么，我都会遇到同样的错误。堆栈跟踪：

我是 Nancy/Linux/dotnet core noob，有人可以解释如何解决这个问题吗？

编辑，工作代码：

引导程序更改：

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
}

启动.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));
    });
}

站点注释：我可能会更改Configuration为Startup.cstype ConfigurationRoot，然后在 - 的构造函数中只进行一次类型转换，而不是像上面那样进行Startup.cs两次。Configure
