Question

我正在使用Unity for Dependencies Injection并使用Identiy Provider来管理用户登录，注册，电子邮件确认等。

当我尝试注册用户时，我遇到了这个问题：

当前类型，Microsoft.Owin.Security.IAuthenticationManager，是一个接口，无法构造。你错过了一个类型吗？映射？

我不知道如何在Unity容器中注册此接口（IAuthenticationManager）。

我尝试使用此代码注册接口，但是如果我说的话，我还有其他问题：

没有注册IUserTokenProvider。

 container.RegisterType<HttpContextBase>(
            new InjectionFactory(_ => new HttpContextWrapper(HttpContext.Current)));
        container.RegisterType<IOwinContext>(new InjectionFactory(c => c.Resolve<HttpContextBase>().GetOwinContext()));
        container.RegisterType<IAuthenticationManager>(
            new InjectionFactory(c => c.Resolve<IOwinContext>().Authentication));

我放了一些app的代码（如果我不使用Unity，一切正常）：

的AccountController

private IAuthenticationManager AuthenticationManager
        {
            get
            {
                return HttpContext.GetOwinContext().Authentication;
            }
        }

IdentityConfig.cs

public class ApplicationUserManager : UserManager<ApplicationUser>
    {
        public ApplicationUserManager(IUserStore<ApplicationUser> store)
            : base(store)
        {

        }

        public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options,
            IOwinContext context)
        {
            var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
            // Configure validation logic for usernames
            manager.UserValidator = new UserValidator<ApplicationUser>(manager)
            {
                AllowOnlyAlphanumericUserNames = false,
                RequireUniqueEmail = true
            };
            // Configure validation logic for passwords
            manager.PasswordValidator = new PasswordValidator
            {
                RequiredLength = 6,
                RequireNonLetterOrDigit = true,
                RequireDigit = true,
                RequireLowercase = true,
                RequireUppercase = true,
            };
            // Configure user lockout defaults
            manager.UserLockoutEnabledByDefault = true;
            manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
            manager.MaxFailedAccessAttemptsBeforeLockout = 5;
            // Register two factor authentication providers. This application uses Phone and Emails as a step of receiving a code for verifying the user
            // You can write your own provider and plug in here.
            manager.RegisterTwoFactorProvider("PhoneCode", new PhoneNumberTokenProvider<ApplicationUser>
            {
                MessageFormat = "Your security code is: {0}"
            });
            manager.RegisterTwoFactorProvider("EmailCode", new EmailTokenProvider<ApplicationUser>
            {
                Subject = "SecurityCode",
                BodyFormat = "Your security code is {0}"
            });
            manager.EmailService = new EmailService();
            manager.SmsService = new SmsService();
            var dataProtectionProvider = options.DataProtectionProvider;
            if (dataProtectionProvider != null)
            {
                manager.UserTokenProvider =
                    new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
            }
            return manager;
        }
    }

    // Configure the RoleManager used in the application. RoleManager is defined in the ASP.NET Identity core assembly

        {
            return new ApplicationRoleManager(new RoleStore<IdentityRole>(context.Get<ApplicationDbContext>()));
        }
    }

    public class EmailService : IIdentityMessageService
    {
        public Task SendAsync(IdentityMessage message)
        {

Answer 1

以下是我使用Unity Identity 2.0实现Unity的好处：

我将以下内容添加到RegisterTypes类中的UnityConfig方法：

container.RegisterType<DbContext, ApplicationDbContext>(
    new HierarchicalLifetimeManager());
container.RegisterType<UserManager<ApplicationUser>>(
    new HierarchicalLifetimeManager());
container.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>(
    new HierarchicalLifetimeManager());

container.RegisterType<AccountController>(
    new InjectionConstructor());

Answer 2

尝试在课程UnityConfig中添加以下行：

container.RegisterType<IAuthenticationManager>(
    new InjectionFactory(
        o => System.Web.HttpContext.Current.GetOwinContext().Authentication
    )
);

Answer 3

如果您真的想使用Unity来管理所有依赖项，您可以尝试在Unity中注册IAuthenticationManager

    container.RegisterType<IAuthenticationManager>(
        new InjectionFactory(c => HttpContext.Current.GetOwinContext().Authentication));

通过一些小的改编，您可以使用Unity来解析Asp.net Identity所需的所有依赖项。

我在这里发现了一篇很棒的文章（也是我测试过的）：

http://tech.trailmax.info/2014/09/aspnet-identity-and-ioc-container-registration/

Answer 4

这也可以作为一个完整的配置，允许Unity与Identity 2.0一起使用：

container.RegisterType<MyDbContext>(new PerRequestLifetimeManager(), new InjectionConstructor());

// Identity
container.RegisterType<UserManager<User>>(new HierarchicalLifetimeManager());
container.RegisterType<SignInManager<User, string>>(new HierarchicalLifetimeManager());
container.RegisterType<IUserStore<User>, UserStore<User>>(new PerRequestLifetimeManager(), new InjectionFactory(x => new UserStore<User>(GetConfiguredContainer().Resolve<MyDbContext>())));
container.RegisterType<IAuthenticationManager>(new InjectionFactory(x => HttpContext.Current.GetOwinContext().Authentication));

使用此设置，您不需要使用Unity注册AccountController或ManageController类型。

Answer 5

声望不会让我评论，但要添加到user3849637s标记答案，对于MVC和Update 3，您还需要添加ManageController，因为一些函数使用更新的脚手架：

container.RegisterType<ManageController>(new InjectionConstructor());

Answer 6

container.RegisterFactory<IAuthenticationManager>(o => System.Web.HttpContext.Current.GetOwinContext().Authentication);

这将回答OP提出的问题，并且是对像我本人一样通过Google找到此问题的任何人的最新回复。 RegisterFactory是在Unity中执行此操作的新方法。

使用Unity注册IAuthenticationManager
