asp.net - ASP.NET Core 5 MVC - Google Auth 不起作用 - 执行登录后没有任何反应

Question

在我登录后 - 什么也没发生，我按照本教程进行操作：https ://docs.microsoft.com/en-us/aspnet/core/security/authentication/social/google-logins?view=aspnetcore-5.0

我读了一些关于令牌的东西..但我没有任何访问权限，它也没有显示在屏幕上或其他东西上。我想也许有一个选项可以在我的 .cshtml 中执行 if() 语句，这样我就可以检查用户是否登录到他的谷歌帐户。

当然，此代码不适用于 Google 身份验证：

@if ((User.Identity.IsAuthenticated) || (Context.User != null && Context.User.Claims != null && Context.User.Claims.Count() > 0))
                    {
                        <li class="nav-item">
                            <a class="nav-link text-dark" asp-area="" asp-controller="Categories" asp-action="Index">Categories</a>
                        </li>
                        <li class="nav-item">

            });
        }
    }
}

应用设置.json

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "ConnectionStrings": {
    "FeedMeContext": "XXXXXX"
  },

  "Authentication": {
    "Google": {
      "ClientId": "XXXX",
      "ClientSecret": "YYYY"
    }
  }
}

但它确实适用于我之前构建的常规 cookie 登录和注册
