AspIdentiy ApplicationUserManager是静态的，如何扩展，使它参与我的IoC框架

在新的asp.net MVC应用程序中，您现在可以免费获得AspIdentity的好处。

有一条无害的小字"在这里插入您的电子邮件服务"。

所以我做了:

public class EmailService : IIdentityMessageService
{
    private static My.Services.IEmailService _emailservice;
    public EmailService(Insolvency.Services.IEmailService emailservice)
    {
        _emailservice = emailservice;
    }
    public Task SendAsync(IdentityMessage message)
    {
        _emailservice.SendEmail(message);
       return Task.FromResult(0);
    }
}

和现在的喜悦:

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    private My.Services.IEmailService _emailservice;
    public ApplicationUserManager(IUserStore<ApplicationUser> store, My.Services.IEmailService emailservice): base(store)        
    {
        _emailservice = emailservice;
    }
    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
    {
        var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()), _emailservice);
       ...

当Owin启动时，它在Startup.Auth.cs:

中调用Create on ApplicationUserManager
public partial class Startup 
   {
    public void ConfigureAuth(IAppBuilder app) 
     {
        ...
        app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);

和我使用AutoFac作为我的IoC容器，在global.asax.cs

builder.RegisterType<My.Services.EmailService>().As<IEmailService>();

如果Create方法是静态的，那么我得到:
_emailService为null

我已经看了这里:http://forums.asp.net/post/5293670.aspx，我如何创建UserManager的实例和使用autofacc提供静态工厂导出的类型。但是运气不好。

如果我改变:

private My.Services.IEmailService _emailservice;
我觉得IoC的神在摇头，我不能构建"需要对象引用"

AspIdentiy ApplicationUserManager是静态的，如何扩展，使它参与我的IoC框架

今天我正在为同样的问题而挣扎(因为我是Asp.Identity的新手，所以还在努力)。我是这样做的:

  1. Startup.cs(使用自己的容器) 

    public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        var authConfigurator = new AuthConfigurator();
        authConfigurator.ConfigureAuth(app);
        var unityContainer = UnityConfig<MvcUnityDependencyContainer>.UseContainer();
        //Asp identity registration
        IDataProtectionProvider dataProtectionProvider = app.GetDataProtectionProvider();
        unityContainer.RegisterInstance(dataProtectionProvider);
        unityContainer.RegisterType<DbContext, ApplicationDbContext>(new HierarchicalLifetimeManager());
        unityContainer.RegisterType<UserManager<ApplicationUser, int>>(new HierarchicalLifetimeManager());
        unityContainer.RegisterType IIdentityMessageService, EmailService>();
        unityContainer.RegisterType<IUserStore<ApplicationUser, int>,
            UserStore<ApplicationUser, CustomRole, int, CustomUserLogin, CustomUserRole, CustomUserClaim>>(
            new InjectionConstructor(new ApplicationDbContext()));
        unityContainer.RegisterType<IIdentityMessageService, EmailService>();
    }
}

  2. ApplicationUserManager(我删除了静态方法Create): 

    public class ApplicationUserManagerService : UserManager<ApplicationUser, int>
{
    public ApplicationUserManagerService(IUserStore<ApplicationUser, int> store, 
                                         IIdentityMessageService emailService,
                                         IDataProtectionProvider dataProtectionProvider)
                                         : base(store)
    {
        UserTokenProvider = new EmailTokenProvider<ApplicationUser, int>();
        EmailService = emailService;
        Configure(dataProtectionProvider);
    }
    private void Configure(IDataProtectionProvider dataProtectionProvider)
    {
        // Configure validation logic for usernames
        UserValidator = new UserValidator<ApplicationUser, int>(this)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };
        // Configure validation logic for passwords
        PasswordValidator = new PasswordValidator
        {
            RequiredLength = 1,
            RequireNonLetterOrDigit = false,
            RequireDigit = false,
            RequireLowercase = false,
            RequireUppercase = false,
        };
        // 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.
        RegisterTwoFactorProvider("PhoneCode", new PhoneNumberTokenProvider<ApplicationUser, int>
        {
            MessageFormat = "Your security code is: {0}"
        });
        RegisterTwoFactorProvider("EmailCode", new EmailTokenProvider<ApplicationUser, int>
        {
            Subject = "Security Code",
            BodyFormat = "Your security code is: {0}"
        });
        if (dataProtectionProvider != null)
        {
            UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser, int>(dataProtectionProvider.Create("ASP.NET Identity"));
        }
    }
}
    3. 控制器

  3. public class AccountController : Controller
{
    private ApplicationUserManagerService _userManagerService;
    public AccountController(ApplicationUserManagerService userManagerService)
    {
        Contract.Requires(userManagerService != null);
        _userManagerService = userManagerService;
    }
    /*....*/
}

  4. ApplicationUser 

    public class ApplicationUser : IdentityUser<int, CustomUserLogin, CustomUserRole, CustomUserClaim>
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser, int> manager)
    {
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        return userIdentity;
    }
}
public class CustomRole : IdentityRole<int, CustomUserRole>
{
    public CustomRole() { }
    public CustomRole(string name) { Name = name; }
}
public class CustomUserClaim : IdentityUserClaim<int> { }
public class CustomUserLogin : IdentityUserLogin<int> { }
public class CustomUserRole : IdentityUserRole<int> { }

这对我有效，但请随时提出更好的解决方案。

今天我为此抗争了很长时间，最后，最简单的事情就是这样做。

内部
public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)

方法，找到这些行代码。

manager.EmailService = new EmailService();
manager.SmsService = new SmsService();

然后改成这个

manager.EmailService = new EmailService(DependencyResolver.Current.GetService<Insolvency.Services.IEmailService>());

我不喜欢服务定位器模式，但是所有的MVC模板化代码都使用它，最好不要与框架对抗。

使用Unity，我将以下内容添加到UnityConfig.cs中的RegisterTypes(IUnityContainer container):

container.RegisterType<ApplicationUserManager>(New InjectionFactory(x => HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>()));

这将获取已经为Startup.ConfigureAuth(IAppBuilder app)中的OwinContext创建的ApplicationUserManager ，并使其可用于注入。您可以将其他所有内容保持默认设置，包括ApplicationUserManager的静态Create方法。
