ASP .NET Core shared Current User

As a quick update to the previous article explaining how to set up JWT and Identity I've updated the currentUser method to use dependency injection.

namespace Craidd.Extensions {
    public static class IHttpContextAccessorExtension
    {
        public static async Task<User> CurrentUser(this IHttpContextAccessor httpContextAccessor)
        {
            IUsersService users = httpContextAccessor.HttpContext.RequestServices.GetService(typeof(IUsersService)) as IUsersService;
            return await users.UserManager.GetUserAsync(httpContextAccessor.HttpContext.User);
        }
    }
}

In my case, IUsersService is a wrapper that contains dbContext, UserManager and SignInManager.

namespace Craidd.Services
{
    public class UsersService: IUsersService
    {
        private readonly AppDbContext _dbContext;
        private readonly UserManager<User> _userManager;
        private readonly SignInManager<User> _signInManager;

        public UsersService(
            AppDbContext context,
            UserManager<User> userManager,
            SignInManager<User> signInManager
        )
        {
            _dbContext = context;
            _userManager = userManager;
            _signInManager = signInManager;
        }

        public UserManager<User> UserManager => _userManager;
        public SignInManager<User> SignInManager => _signInManager;
    }
}

Now in your controller you can easily access the method by injecting httpContext.
I'm currently using it to quickly return the logged in user data for the Nuxt.js Auth Module

[HttpGet]
public IActionResult Index()
{
    return Json(new { user = _httpContext.CurrentUser() });
}
