如何使用标识以编程方式在asp.net 5中创建用户

Question

I´m trying to create some users in a seed method, but no luck.

I had used this example: How to add role and Users in asp.net mvc 5? but the UserManager seams to be instantiate in a different way.

Looking in the AccountController , this instance is loaded in the constructor:

    public AccountController(
        UserManager<ApplicationUser> userManager,
        SignInManager<ApplicationUser> signInManager,
        IEmailSender emailSender,
        ISmsSender smsSender,
        BennerCliContext applicationDbContext)
    {
        _userManager = userManager;
        _signInManager = signInManager;
        _emailSender = emailSender;
        _smsSender = smsSender;
        _applicationDbContext = applicationDbContext;
    }

But my seed method lies on the MyDbContext class.

How can I access the UserManager instance from there?

There are another ways to create users in vnext ?

update

After @Vladislav Karamfilov suggestion:

Answer 1

Since user manager already had been registered in ASP.NET5's service provider you could easily get instance of user manager by calling following method:

 var userManager=new HttpContextAccessor()
     .HttpContext.ApplicationServices.GetService(typeof(UserManager<ApplicationUser>));

Answer 2

You should create an instance of UserManager<ApplicationUser> and then use the CreateIdentity method to create an ApplicationUser object. However if you assign Administrator role to the created user and your code is public be really careful not to expose your site's security .
