Endpoint包含授权元数据，但未找到支持授权的中间件

我目前正在将本地开发的应用程序迁移到数字海洋中的 Ubuntu 16.04 Droplet。我正在使用 .NET Core 3.1 并已为其配置了我的服务器。但是，当我导航到控制器上使用[Authorize]属性，我仅在我的生产服务器上（而不是本地）收到以下异常：

An unhandled exception has occurred while executing the request.
System.InvalidOperationException: Endpoint App.Controllers.RsvpController.Index contains authorization metadata, but a middleware was not found that supports authorization.
Configure your application startup by adding app.UseAuthorization() inside the call to Configure(..) in the application startup code. The call to app.UseAuthorization() must appear between app.UseRouting() and app.UseEndpoints(...).

fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[1]
An unhandled exception has occurred while executing the request.

这就是我的Configure()方法看起来像Startup.cs:

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }

            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
            });
        }

我也在使用这个ConfigureServices():

            services.AddAuthentication(options =>
            {
                options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                options.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            }).AddCookie(options =>
            {
                options.LoginPath = new PathString("/Account/Login/");
                options.AccessDeniedPath = new PathString("/Account/Forbidden/");
            });

我的控制器有[Authorize]整个控制器类的属性：

    [Authorize]
    public class RsvpController : Controller
    {
        ...
    }

我无法弄清楚问题是什么，因为它在本地工作。我尝试在本地将 ASPNETCORE_ENVIRONMENT 更改为“生产”，以查看是否有基于此的标志，但我仍然遇到问题。预先感谢您的任何帮助！

In your Configure方法，尝试这段代码：

...
app.UseAuthentication();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
    endpoints.MapControllers();
});
