我的 AspNet Core 3.1 身份页面在 IdentityServer4 中给出了 404。我怎样才能访问这些？这是路径问题吗？

Question

我遵循了这里的 Deblokt 教程，该教程详细解释了如何在 .net core 3.1 中设置 IdentityServer4 并为用户存储使用 AspNetCore Identity。

我可以从https://localhost:5001/Account/Login url（和注销）登录到我的 IdentityServer就好了......但我无法访问 AspNet Core Identity 页面（例如 Register/ForgotPassword/AccessDenied 等）。我已经将它们放在脚手架上，所以它们位于 Areas/Identity/Pages/Account 下...但是当我导航到它们时，例如https://localhost:5001/Identity/Account/Register，我只是找不到 404。

我不确定，但怀疑这可能是路由问题，所以我研究了为这些页面提供路由，但我看到的 IdentityServer 示例适用于 Core2.1 并使用 app.UseMVC ...我的启动不具有。我试图包含它，但我收到错误消息

端点路由不支持“IApplicationBuilder.UseMvc(...)”。要使用 'IApplicationBuilder.UseMvc' 在 'ConfigureServices(...)' 中设置 'MvcOptions.EnableEndpointRouting = false'

那么我该往哪里去呢？

我从 GitHub 下载了随附解决方案的教程，但它是 Core 2.1 解决方案，因此怀疑该教程是重写/升级到 3.1 的版本。

这是我的启动文件...

public class Startup

        public IWebHostEnvironment Environment { get; }
        public IConfiguration Configuration { get; }
        public Startup(IWebHostEnvironment environment, IConfiguration configuration)

Answer 1

嗯，这是我的 startup.cs 文件中的 1 行代码

app.UseEndpoints(endpoints =>
{
    endpoints.MapDefaultControllerRoute();
    endpoints.MapRazorPages(); // This one!
});

哦，如果有人遇到它，注册页面上会发生另一个错误。

无法解析“Microsoft.AspNetCore.Identity.UI.Services.IEmailSender”类型的服务

只需将以下代码行添加到 Startup.cs 中的 ConfigureServices 方法的末尾

services.AddTransient<IEmailSender,SomeEmailSender>();

IEmailSender 来自 Microsoft.AspNetCore.Identity.UI.Services。只需创建一个实现此接口的类并在此处声明即可。
