SWAGGER UI 不显示 - Swagger.json 在 .NET Core 上显示

Question

当我点击 http://localhost:5000/swagger/index.html 时，SWAGGER UI 不显示，而我可以在 http://localhost:5000/swagger/v1/swagger 访问 Swagger.json。 json

即

这是我的 program.cs

中的内容

 public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>();

Startup.cs - 配置

app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                foreach (var description in provider.ApiVersionDescriptions.OrderByDescending(o => o.GroupName))
                {
                    c.SwaggerEndpoint(
                        $"/swagger/{description.GroupName}/swagger.json",
                        description.GroupName.ToUpperInvariant());
                }
            });

以及Startup.cs - 配置服务

//Swagger Services.
            services.AddTransient<IConfigureOptions<SwaggerGenOptions>, ConfigureSwaggerOptions>();
            if (this.Configuration["EnableSwagger"] == "true")
            {
                //services.AddSwaggerGen(opt =>
                //opt.SwaggerDoc("v1", new Info { Title = "My API", Version = "v1" });

                //// Set the comments path for the Swagger JSON and UI.
                //var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
                //var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
                //opt.IncludeXmlComments(xmlPath);
                services.AddSwaggerGen(opt =>
                {
                    opt.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
                    {
                        Name = "Authorization",
                        Type = SecuritySchemeType.ApiKey,
                        Scheme = "bearer",
                        BearerFormat = "JWT",
                        In = ParameterLocation.Header,
                        Description = "JWT Authorization header using the Bearer scheme."
                    });
                    opt.AddSecurityRequirement(new OpenApiSecurityRequirement
                    {
                        {
                          new OpenApiSecurityScheme
                            {
                                Reference = new OpenApiReference
                                {
                                    Type = ReferenceType.SecurityScheme,
                                    Id = "Bearer"
                                }
                            },
                            Array.Empty<string>()
                        }
                    });
                });
            }

其中的ConfigureSwaggerOptions在下面

public class ConfigureSwaggerOptions : IConfigureOptions<SwaggerGenOptions>
    {
        readonly IApiVersionDescriptionProvider _apiVerProvider;

        public ConfigureSwaggerOptions(IApiVersionDescriptionProvider apiVerProvider) => _apiVerProvider = apiVerProvider;

        public void Configure(SwaggerGenOptions options)
        {
            foreach (var description in _apiVerProvider.ApiVersionDescriptions)
            {
                options.SwaggerDoc(description.GroupName, GetSwaggerDocInfo(description));
            }
        }

        static OpenApiInfo GetSwaggerDocInfo(ApiVersionDescription description)
        {
            var info = new OpenApiInfo
            {
                Title = $"WebAPI {description.ApiVersion}",
                Version = description.GroupName,
                Description = "Web API Template",
                Contact = new OpenApiContact()
                {
                    Name = "Web API service"
                },
                License = new OpenApiLicense()
                {
                    Name = "MIT"
                }
            };

            if (description.IsDeprecated)
            {
                info.Description += $" {description.ApiVersion} API version is deprecated.";
            }
            return info;
        }
    }

我可以将 swagger.json 导入邮递员。但是，招摇的用户界面没有显示出来。

   app.UseSwagger();
