【中文标题】我的 AspNet Core 3.1 身份页面在 IdentityServer4 中给出 404。我怎样才能访问这些？这是路线问题吗？

【英文标题】：My AspNet Core 3.1 Identity Pages give a 404 in IdentityServer4. How can I access these? Is this a route problem?

【问题描述】：

我遵循了 Deblokt 教程 here，它详细解释了如何在 .net core 3.1 中设置 IdentityServer4 并将 AspNetCore Identity 用于用户存储。

我可以从https://localhost:5001/Account/Login url 登录到我的IdentityServer（和注销）就好了......但我无法访问AspNet Core Identity 页面（例如Register/ForgotPassword/AccessDenied 等）。我已经把它们搭建好了，所以它们位于区域/身份/页面/帐户下...但是当我导航到它们时，例如https://localhost:5001/Identity/Account/Register，我只是得到一个 404 未找到。

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 示例是针对 Core2.1 并使用 app.UseMVC ...我的创业公司没有。我试图包含它，但我收到错误提示

端点路由不支持“IApplicationBuilder.UseMvc(...)”。 使用“IApplicationBuilder.UseMvc”集 'MvcOptions.EnableEndpointRouting = false' 里面 '配置服务（...）'

那么我该去哪里呢？

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 3.1 的重写/升级版本。

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)
        
            Environment = environment;
            Configuration = configuration;
        

        public void ConfigureServices(IServiceCollection services)
        
            // uncomment, if you want to add an MVC-based UI
            services.AddControllersWithViews();
            services.AddRazorPages(); // I recently added this, but made no difference

            string connectionString = Configuration.GetConnectionString("DefaultConnection");

            var migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;

            services.AddDbContext<IdentityDbContext>(options =>
                options.UseSqlServer(connectionString, sql => sql.MigrationsAssembly(migrationsAssembly))
            );

            services.AddDbContext<Data.ConfigurationDbContext>(options => options.UseSqlServer(connectionString, sql => sql.MigrationsAssembly(migrationsAssembly)));

            services.AddIdentity<ApplicationUser, IdentityRole>(options =>
            
                options.SignIn.RequireConfirmedEmail = true;
            )
            .AddEntityFrameworkStores<IdentityDbContext>()
            .AddDefaultTokenProviders();

            var builder = services.AddIdentityServer(options =>
            
                options.Events.RaiseErrorEvents = true;
                options.Events.RaiseInformationEvents = true;
                options.Events.RaiseFailureEvents = true;
                options.Events.RaiseSuccessEvents = true;
                options.UserInteraction.LoginUrl = "/Account/Login";
                options.UserInteraction.LogoutUrl = "/Account/Logout";
                options.Authentication = new AuthenticationOptions()
                
                    CookieLifetime = TimeSpan.FromHours(10), // ID server cookie timeout set to 10 hours
                    CookieSlidingExpiration = true
                ;
            )
            .AddConfigurationStore(options =>
            
                options.ConfigureDbContext = b => b.UseSqlServer(connectionString, sql => sql.MigrationsAssembly(migrationsAssembly));
            )
            .AddOperationalStore(options =>
            
                options.ConfigureDbContext = b => b.UseSqlServer(connectionString, sql => sql.MigrationsAssembly(migrationsAssembly));
                options.EnableTokenCleanup = true;
            )
            .AddAspNetIdentity<ApplicationUser>();

            X509Certificate2 cert = null;

            using (X509Store certStore = new X509Store(StoreName.My, StoreLocation.CurrentUser))
            
                certStore.Open(OpenFlags.ReadOnly);
                X509Certificate2Collection certCollection = certStore.Certificates.Find(
                    X509FindType.FindByThumbprint,
                    // Replace below with your cert's thumbprint
                    "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" // Replaced for this post
                    ,
                    false);
                // Get the first cert with the thumbprint
                if (certCollection.Count > 0)
                
                    cert = certCollection[0];
                
            

            // Fallback to local file for development
            if (cert == null)
            
                cert = new X509Certificate2(Path.Combine(Environment.ContentRootPath, "xxxxxxxxx.pfx"), "xxxxxxxxxxxxxxxxxxxxx"); // Replaced for this post
            

            // not recommended for production - you need to store your key material somewhere secure
            //builder.AddDeveloperSigningCredential();
            builder.AddSigningCredential(cert);
            builder.AddValidationKey(cert);

            services.AddScoped<IProfileService, ProfileService>();

        

        public void Configure(IApplicationBuilder app)
        
            if (Environment.IsDevelopment())
            
                app.UseDeveloperExceptionPage();
            

            // uncomment if you want to add MVC
            app.UseStaticFiles();
            app.UseRouting();

            app.UseIdentityServer();

            // uncomment, if you want to add MVC
            app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            
                endpoints.MapDefaultControllerRoute();
            );
        
    

【参考方案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，注册页面上会出现另一个错误。

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

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

services.AddTransient<IEmailSender,SomeEmailSender>();

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