在 ASP.NET 5 中使用 IdentityServer3.AccessTokenValidation 的 owin middlware？返回空对象异常

Question

我正在尝试让 IdentityServer3.AccessTokenValidation 在 ASP.NET 5 Web 应用程序中工作，但下面的代码会引发空异常，我是否遗漏了什么？

project.json - 依赖项（部分）

"IdentityServer3.AccessTokenValidation": "2.0.0-build00019",
"Microsoft.AspNet.WebApi.Owin": "5.2.3",
"Microsoft.Owin.Host.SystemWeb": "3.0.1",
"Microsoft.AspNet.Authentication.OAuthBearer": "1.0.0-beta6",
"Microsoft.Owin.Security.OAuth": "3.0.0",
"Microsoft.AspNet.Owin": "1.0.0-beta6",
"Microsoft.AspNet.Authorization": "1.0.0-beta6",
"Microsoft.IdentityModel.Protocol.Extensions": "1.0.0",
"Newtonsoft.Json": "6.0.6"

Startup.cs

        app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions
        {
            Authority = "https://localhost:44300/",
            RequiredScopes = new[] { "api1" }
        });

扩展方法

    public static void UseIdentityServerBearerTokenAuthentication(this IApplicationBuilder app, IdentityServerBearerTokenAuthenticationOptions options)
    {
        app.UseOwin(addToPipeline =>
        {
            addToPipeline(next =>
            {
                var builder = new Microsoft.Owin.Builder.AppBuilder();

                builder.UseIdentityServerBearerTokenAuthentication(options);

                var appFunc = builder.Build(typeof(Func<IDictionary<string, object>, Task>)) as Func<IDictionary<string, object>, Task>;
                return appFunc;
            });
        });
    }

以下行继续抛出空对象异常但无法确定缺少什么

builder.UseIdentityServerBearerTokenAuthentication(options);

我也有这个 NullPointerException。问题是方法app.GetLoggerFactory(); （来自 IAppBuilder）返回 null。 就我而言，此方法在我调用后返回 null

app.Map("/admin", adminApp =>
        {
            var factory = new IdentityManagerServiceFactory();
            factory.ConfigureSimpleIdentityManagerService();

            adminApp.UseIdentityManager(new IdentityManagerOptions()
            {
                Factory = factory
            });
        });

因此将方法builder.UseIdentityServerBearerTokenAuthentication(options); 放在app.Map 之前解决了NullPointer 问题。 但是现在我有一个问题，似乎不可能在同一个项目中托管 WebApi 和 IdentityServer，但这是另一个问题..
