我有一个 ASP.NET Core 5 MVC 应用程序，其中默认/根路由设置如下PageController：

[AllowAnonymous]
[Route("/")]
public IActionResult __Home(int? parent)
{
    return View();
}

在我添加 OpenIdConnect 身份验证之前，这一直很好。之后，根 ( /) 页面不再路由到__Home中PageController，它只是返回一个空白页面。所有其他页面路由都很好。

当我注释掉这个时：

services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
        .AddMicrosoftIdentityWebApp(Configuration, "AzureAdB2C");

然后/再次工作，所以我知道这与身份验证有关。如您所见，我已添加[AllowAnonymous]到该操作中。

我的启动中有这个：

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

有想法该怎么解决这个吗？我知道在这样的奇怪控制器/动作中使用默认/根路由是非常规的，但这是有原因的，所以我希望它仍然可以工作。

更多信息：

我发现如果我移到app.UseEndpoints上面app.UseAuthentication，那么主页就会显示。然而，在登录（使用 B2C）后，它进入了一个无限循环（即身份验证令牌不粘？）。

编辑：我的 Startup.cs 类

using Blank.Models;
using Microsoft.AspNetCore.Authentication.OpenIdConnect;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc.Authorization;
using Microsoft.EntityFrameworkCore;

namespace Blank
{
    public class Startup
    {
        private readonly AppSettings appSettings = null;

        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
            this.appSettings = new AppSettings();
            this.Configuration.Bind(this.appSettings);
        }

        public IConfiguration Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            
            services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
                .AddMicrosoftIdentityWebApp(Configuration, "AzureAdB2C");

            services.AddSession();

            services.Configure<OpenIdConnectOptions>(Configuration.GetSection("AzureAdB2C"));

            services.AddControllersWithViews(options =>
            {
                var policy = new AuthorizationPolicyBuilder()
                    .RequireAuthenticatedUser()
                    .Build();
                options.Filters.Add(new AuthorizeFilter(policy));
            });


            services.Configure<AppSettings>(this.Configuration);

            services.AddEntityFrameworkSqlServer().AddDbContext<BlankDBContext>(
               Options => Options.UseSqlServer(Microsoft.Extensions.Configuration.ConfigurationExtensions.GetConnectionString(this.Configuration, "BlankDatabase"))
                );
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        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.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();


            app.UseSession();

            app.UseAuthentication();

            app.UseAuthorization();

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

        }
    }

}

我认为这是破坏/返回空白页，因为当我在主页上获得某些app.UseAuthentication()内容之前放置以下代码时，如果它之后则为空白：app.UseAuthentication()

app.Use(async (context, next) =>
{
    var endpoint = context.GetEndpoint();

    if (endpoint != null)
    {
        await context.Response.WriteAsync("<html> Endpoint :" + endpoint.DisplayName + " <br>");

        if (endpoint is RouteEndpoint routeEndpoint)
        {
            await context.Response.WriteAsync("RoutePattern :" + routeEndpoint.RoutePattern.RawText + " <br>");
        }

    }
    else
    {
        await context.Response.WriteAsync("End point is null");
    }

    await context.Response.WriteAsync("</html>");
    await next();
});

所以也许它与我的身份验证有关？这是我的appsettings.json：

"AzureAdB2C": {
    "Instance": "https://abc.b2clogin.com",
    "Domain": "abc.onmicrosoft.com",
    "ClientId": "62...f1",
    "TenantId": "7e...ae",
    "SignUpSignInPolicyId": "B2C_1_SUSI",
    "SignedOutCallbackPath": "/"
},

原来问题出在我的appsettings.json：

"SignedOutCallbackPath": "/"

删除它解决了问题，主页现在可以正确加载。
