Question

我正在使用身份，但遇到一个问题，即我制作了一个新的示例项目，并具有个人身份验证和支架身份 InvalidOperationException：尝试激活“ MASQ.Areas.Identity.Pages.Account.RegisterModel”时，无法解析类型为“ Microsoft.AspNetCore.Identity.UI.Services.IEmailSender”的服务。

Answer 1

有两种方法可以做到这一点：

删除services.AddDefaultTokenProviders()中的ConfigurureServices()以禁用two-factor authentication (2FA)：

//文件：Startup.cs：

services.AddDefaultIdentity<IdentityUser>()
    .AddEntityFrameworkStores<ApplicationDbContext>();
    ///.AddDefaultTokenProviders(); /// remove this line

如果您想启用IEmailSender，请在DI容器中添加自己的ISmsSender和2FA实现

//文件：Startup.cs

services.AddTransient<IEmailSender,YourEmailSender>();
services.AddTransient<IEmailSender,YourSmsSender>();

两者都应该起作用。

Answer 2

我正在使用ASP.NET Core 3.0，并且遇到了类似的问题。我在Startup.cs中添加了以下.AddDefaultUI（）并成功运行。

 public void ConfigureServices(IServiceCollection services)
        {
            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(
                    Configuration.GetConnectionString("DefaultConnection")));
            services.AddIdentity<IdentityUser, IdentityRole>()
                .AddDefaultTokenProviders()
                .AddDefaultUI()
                .AddEntityFrameworkStores<ApplicationDbContext>();

            services.AddControllersWithViews();
            services.AddRazorPages().AddRazorRuntimeCompilation();
        }

Answer 3

对于 ASP.NET Core 5.0，您可以使用以下代码，而不是调用 AddIdentity

services.AddDefaultIdentity<IdentityUser>(options => options.SignIn.RequireConfirmedAccount = true)
            .AddEntityFrameworkStores<AppDbContext>()
            .AddDefaultTokenProviders();

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });
        services.AddDbContext<ApplicationDbContext>(options =>
        options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
        services.AddIdentity<ApplicationUser, ApplicationRole>(
           option => {
               option.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(5);
               option.Lockout.MaxFailedAccessAttempts = 5;
               option.Lockout.AllowedForNewUsers = false;
           })
          .AddEntityFrameworkStores<ApplicationDbContext>()
          .AddDefaultTokenProviders();

        //services.AddDbContext<ApplicationDbContext>(options =>
        //    options.UseSqlServer(
        //        Configuration.GetConnectionString("DefaultConnection")));
        //services.AddIdentity<ApplicationUser, IdentityRole>()
        //    .AddEntityFrameworkStores<ApplicationDbContext>().AddDefaultTokenProviders();

        services.AddTransient<Areas.Identity.Services.IEmailSender, AuthMessageSender>();

        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseDatabaseErrorPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            app.UseHsts();
        }

        app.UseHttpsRedirection();
        app.UseStaticFiles();
        app.UseCookiePolicy();

        app.UseAuthentication();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });
    }
}

Answer 5

在配置服务中添加默认UI：

services.AddIdentity<IdentityUser, IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders()
    .AddDefaultUI();

尝试激活RegisterModel时无法解析IEmailSender类型的服务
