更改ASP.NET Core Razor頁面默認頁面為Login登錄頁面

我整理了一個示例，展示了如何執行此操作：https : //github.com/mkArtakMSFT/Samples/blob/master/CustomPageRouteConvention/Conventions/DefaultRouteRemovalPageRouteModelConvention.cs

using Microsoft.AspNetCore.Mvc.ApplicationModels;


public class DefaultRouteRemovalPageRouteModelConvention : IPageRouteModelConvention
    {
        private string routeToRemove;

        public DefaultRouteRemovalPageRouteModelConvention(string pageRoute)
        {
            this.routeToRemove = pageRoute;
        }

        public void Apply(PageRouteModel model)
        {
            for (int i = 0; i < model.Selectors.Count; i++)
            {
                var selector = model.Selectors[i];
                for (int j = 0; j < selector.EndpointMetadata.Count; j++)
                {
                    if ((selector.EndpointMetadata[j] as PageRouteMetadata)?.PageRoute == routeToRemove)
                    {
                        model.Selectors.Remove(selector);
                        return;
                    }
                }
            }
        }
    }

Startup.cs

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddRazorPages(options=>
            {
                options.Conventions.Add(new DefaultRouteRemovalPageRouteModelConvention(String.Empty));
                options.Conventions.AddPageRoute("/Login", "");
            });
        }
