.NET & Swagger 开始出现 401 错误

Question

我已经为我的 .NET Core webApi 应用程序配置了 Swagger，这是它的配置

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddAuth();

            services.AddCors(options =>
            {
                options.AddPolicy("CorsPolicy",
                    builder => builder.AllowAnyOrigin()
                        .AllowAnyMethod()
                        .AllowAnyHeader()
                        .AllowCredentials()
                        .Build());
            });

            services.AddMvc();
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1",
                    new Info
                    {
                        Version = "v1",
                        Title = "XXX Synchronization API",
                        Description = "XXX Synchronization API",
                        TermsOfService = "None",
                        Contact = new Contact { Name = "XXX Inc.", Email = "XXXX", Url = "XXX.com" }
                    });
                c.IncludeXmlComments(GetXmlCommentsPath());
                c.DescribeAllEnumsAsStrings();
            });

            services.AddSingleton<IHashProvider, Pbkdf2Version1HashProvider>();
            services.AddSingleton<IPasswordHasher, PasswordHasher>();
            services.AddTransient<IAuthenticationService, GfdAuthenticationService>();
            services.AddSingleton(new GfdSqlServerDatabase(Gfd2Configuration.Settings.GfdSqlServerConnectionString));
            services.AddSingleton(new MySqlSyncDatabase(Gfd2Configuration.Settings.AwsMySqlConnectionString));
            services.AddTransient<SyncRepository, AwsMySqlSyncRepository>();
            services.AddHostedService<QueuedHostedService>();
            services.AddSingleton<IBackgroundTaskQueue, BackgroundTaskQueue>();
            services.AddSingleton<ArchivedJobProcessorBase, ArchivedJobProcessorFeatures>();
        }

        /// <summary>
        /// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        /// </summary>
        /// <param name="app"></param>
        /// <param name="env"></param>
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseAuthentication();
            app.UseCors("CorsPolicy");
            app.UseMvc();

            app.UseSwagger();

#if DEBUG
            app.UseSwaggerUI(c => { c.SwaggerEndpoint("/swagger/v1/swagger.json", "XXXX Synchronization API V1"); });
#else
            app.UseSwaggerUI(c => { c.SwaggerEndpoint("/sync/swagger/v1/swagger.json", "XXX Synchronization API V1"); });
#endif
        }

一切都运行良好。由于某种原因，今天早上我每次打开该/swagger网址时都会收到 401 错误。我不需要对 Swagger 文档和 UI 进行任何身份验证，所有内容都是公开的。

这可能与 相关吗.NET Core 2.1.2？

使用Swashbuckle.AspNetCore 3.0.0

欢迎任何想法。

对于那些可能遇到此类问题的人来说，修复实际上非常简单。对于实际上需要身份验证的新 webApi 控制器之一，我忘记添加 attribute [Route("api/[controller]")]，因此/swaggerurl 指向该控制器，从而出现 401 错误。去搞清楚 ：）
