在ASP.NET Web应用程序之外获取UserManager实例？

我有一个带有ASP.NET标识（个人帐户）的ASP.NET MVC 5 Web应用程序。但是我需要能够从控制台应用程序注册新用户。

因此，我将一些ASP.NET Identity类从Web应用程序移到类库中，以在Web应用程序和CLI之间共享。

我已经成功移动了以下内容：

public class PortalDbContext : IdentityDbContext<PortalUser>
{
    public PortalDbContext(string connectionString)
        : base(connectionString, throwIfV1Schema: false)
    {
    }

    public static PortalDbContext Create(string connectionString)
    {
        return new PortalDbContext(connectionString);
    }
}

public class PortalUser : IdentityUser
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<PortalUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);

        // Add custom user claims here
        return userIdentity;
    }
}

public class PortalUserManager : UserManager<PortalUser>
{
    public PortalUserManager(IUserStore<PortalUser> store) : base(store)
    {
    }

    public async Task<IdentityResult> RegisterUser(string email, string password)
    {
        PortalUser user = new PortalUser { UserName = email, Email = email };

        return await this.CreateAsync(user, password);
    }
}

但我不知道从哪里得到IUserStore<PortalUser>的PortalUserManager，从需求。

在Web应用程序中，检索到HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>()了我显然不能在类库中使用的该管理器。

我已经结束了加入一个静态方法Create(string connectionString)来PortalUserManager将创建UserStore并DbContext返回经理的新实例。

public class PortalDbContext : IdentityDbContext<PortalUser>
{
    public PortalDbContext(string connectionString)
        : base(connectionString, throwIfV1Schema: false)
    {
    }

    public static PortalDbContext Create(string connectionString)
    {
        return new PortalDbContext(connectionString);
    }
}

public class PortalUser : IdentityUser
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<PortalUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);

        // Add custom user claims here
        return userIdentity;
    }
}

public class PortalUserManager : UserManager<PortalUser>
{
    public PortalUserManager(IUserStore<PortalUser> store) : base(store)
    {
    }

    public static PortalUserManager Create(string connectionString)
    {
        UserStore<PortalUser> userStore = new UserStore<PortalUser>(PortalDbContext.Create(connectionString));

        PortalUserManager manager = new PortalUserManager(userStore);

        // Configure validation logic for usernames
        manager.UserValidator = new UserValidator<PortalUser>(manager)
        {
            AllowOnlyAlphanumericUserNames = true,
            RequireUniqueEmail = true                
        };

        // Configure validation logic for passwords
        manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = true,
            RequireDigit = true,
            RequireLowercase = true,
            RequireUppercase = true,
        };

        return manager;
    }

    public async Task<IdentityResult> RegisterUser(string email, string password)
    {
        PortalUser user = new PortalUser { UserName = email, Email = email };

        return await this.CreateAsync(user, password);
    }
}
