c# - ConfigurationManager.GetConfigurationAsync 无法在 TestServer 中检索身份配置

Question

我正在使用Microsoft.AspNetCore.TestHost版本 2.2.0 和Microsoft.NET.Test.Sdk版本 15.9.0。我将 IdentityServer4 用于 OAuth2 提供程序以进行 Jwt Bearer 身份验证。使用真正的 Web 服务器部署时，该设置运行良好。但是，在使用TestServer.

我已经注册了HttpMessageHandler：

private void InitializeServices<TStartup>(IServiceCollection services)
{
      var startupAssembly = typeof(TStartup).GetTypeInfo().Assembly;

      var applicationPartManager = new ApplicationPartManager();
      applicationPartManager.ApplicationParts.Add(new AssemblyPart(startupAssembly));
      applicationPartManager.FeatureProviders.Add(new ControllerFeatureProvider());
      applicationPartManager.FeatureProviders.Add(new ViewComponentFeatureProvider());

      services.AddSingleton(applicationPartManager);

      services.PostConfigure<IdentityServerAuthenticationOptions>(options =>
                                                                        {
                                                                            options.IntrospectionDiscoveryHandler = this.server.CreateHandler();
                                                                            options.IntrospectionBackChannelHandler = this.server.CreateHandler();
                                                                            options.JwtBackChannelHandler = this.server.CreateHandler();
                                                                        });
}

this.server我的测试服务器在哪里。但是，当我运行集成测试时，出现以下错误。
