I have tried to implement Okta login in my app. I'm running a test app to figure it out before I edit the real app. I load the url and it authenticates through Okta as it should. Then it does to a page saying "Loading..." for a few seconds and then gives an error:

本地重定向(RedirectUri)应该重定向到"/".相反，它再次循环回到Login函数.

using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Mvc;

namespace TestOktaLogin.Controllers {
    public class LoginController : Controller {
        [HttpGet("Login")]
        public IActionResult Login([FromQuery] string returnUrl) {
            var redirectUri = returnUrl is null ? "/" : "/" + returnUrl;

            if (User.Identity.IsAuthenticated) {
                return LocalRedirect(redirectUri); //It does not return. It just reloads the function.
            }

            return Challenge();
        }

        // This is the method the Logout button should get to when clicked.
        [HttpGet("Logout")]
        public async Task<ActionResult> Logout([FromQuery] string returnUrl) {
            var redirectUri = returnUrl is null ? Url.Content("~/") : "/" + returnUrl;

            if (!User.Identity.IsAuthenticated) {
                return LocalRedirect(redirectUri);
            }

            await HttpContext.SignOutAsync();

            return LocalRedirect(redirectUri);
        }
    }
}

重定向到登录.

using Microsoft.AspNetCore.Components;

namespace TestOktaLogin.Components {
    public partial class RedirectToLogin : ComponentBase {
        [Inject] public NavigationManager Navigation { get; set; }

        protected override async Task OnInitializedAsync() {
            var returnUrl = Navigation.ToBaseRelativePath(Navigation.Uri);

            Navigation.NavigateTo($"Login?returnUrl={returnUrl}", true);
        }
    }
}```

Hello, world!

欢迎使用您的新apply.`

Program.cs:

using Microsoft.AspNetCore.Authentication.OpenIdConnect;
using TestOktaLogin.Components;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents();

builder.Services.AddMvc();

builder.Services.AddAuthentication(authOptions => {
    authOptions.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    authOptions.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    authOptions.DefaultSignOutScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    authOptions.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
}).AddOpenIdConnect(oidcOptions => {
    oidcOptions.ClientId = builder.Configuration["Okta:ClientId"];
    oidcOptions.ClientSecret = builder.Configuration["Okta:ClientSecret"];
    oidcOptions.CallbackPath = "/authorization-code/callback";
    oidcOptions.Authority = builder.Configuration["Okta:Issuer"];
    oidcOptions.ResponseType = "code";
    oidcOptions.SaveTokens = true;
    oidcOptions.Scope.Add("openid");
    oidcOptions.Scope.Add("profile");
    oidcOptions.TokenValidationParameters.ValidateIssuer = false;
    oidcOptions.TokenValidationParameters.NameClaimType = "name";
}).AddCookie();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment()) {
    app.UseExceptionHandler("/Error", createScopeForErrors: true);
    // 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.UseAntiforgery();

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

app.MapControllers();

app.MapRazorComponents<App>()
    .AddInteractiveServerRenderMode();

app.Run();

编辑: 这是我的路由.剃须刀

@using TestOktaLogin.Components.Layout

<CascadingValue Name="AccessToken" Value="AccessToken">
    <CascadingAuthenticationState>
        <Router AppAssembly="@typeof(App).Assembly">
            <Found Context="routeData">
                <AuthorizeRouteView RouteData=@routeData DefaultLayout="@typeof(MainLayout)">
                    <NotAuthorized>
                        <RedirectToLogin /> @* Would this cause the problem? *@
                    </NotAuthorized>
                    <Authorizing>
                        Authorizing...
                    </Authorizing>
                </AuthorizeRouteView>
            </Found>
            <NotFound>
                <PageTitle>Not found</PageTitle>
                <LayoutView Layout="@typeof(MainLayout)">
                    <p role="alert">Sorry, there's nothing at this address.</p>
                </LayoutView>
            </NotFound>
        </Router>
    </CascadingAuthenticationState>

</CascadingValue>

@code{
    [Parameter] public string AccessToken { get; set; }
}

这是MainLayout.razor

@inherits LayoutComponentBase

<div>
    <LoginDisplay/>
</div>

@Body

<div id="blazor-error-ui">
    An unhandled error has occurred.
    <a href="" class="reload">Reload</a>
    <a class="dismiss">🗙</a>
</div>

如果有任何额外的代码我需要上传，让我知道.谢谢你的帮助！
