How can I get my own User in controller in Asp.net core mvc

Question

I have User class:

public class User : Entity
{

    public void AcceptMenu(Menu menu)
    {
      //AcceptMenu 
    }      
    public string Login { get; set; }
    public string Password { get; set; }
    public string Salt { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

And I create authorization logic. Authenticate method looks like this:

      private async Task Authenticate(User user)
    {

        var claims = new List<Claim>
        {
            new Claim(ClaimsIdentity.DefaultNameClaimType, user.Login),
            new Claim(ClaimsIdentity.DefaultRoleClaimType, user.Role)
        };

        ClaimsIdentity id = new ClaimsIdentity(claims, "ApplicationCookie", ClaimsIdentity.DefaultNameClaimType, ClaimsIdentity.DefaultRoleClaimType);

        await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(id));
    }

As you can see I have AcceptMenu method in User. How can I get User in Controller and execute AcceptMenu method?

Controller has property User with IPrincipal type. You can get name of user with User.Identity.Name But it is name of Authenticated asp.net user. You can map this Authenticated user with your user class. in controller

ApplicationUserManager UserManager = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();

ApplicationUser  user = await UserManager.FindByEmailAsync(User.Identity.Name);

Where ApplicationUserManager is class with identity config , and ApplicationUser is IdentityUser from this class. But it is not your db User derived from entity class, it should be mapped manually

Are you suggesting get user like: `var user = appContext.Users.Single(a => a.Login == User.Identity.Name);` ? – Dilshod K May 17 '19 at 08:55
Yes it is correct way, also you could use [dbo].[AspNetUsers] but it is not extendable approach – Oleg Bondarenko May 17 '19 at 09:01

You can always use var loggedInUser = await useManager.GetUserAsync(User) to get the user if you are logged in.
