错误的 ID 用户 - ASP NET CORE

Question

我正在使用 ASP.NET CORE 2.0，并且必须获取已登录的用户 ID。这是我的帐户控制人：

[Route("[controller]/[action]")]
public class AccountController : Controller
{
    private readonly SignInManager<ApplicationUser> _signInManager;
    private readonly ILogger _logger;
    private readonly UserManager<ApplicationUser> _userManager;

    public AccountController(SignInManager<ApplicationUser> signInManager, ILogger<AccountController> logger, UserManager<ApplicationUser> userManager)
    {
        _signInManager = signInManager;
        _logger = logger;
        _userManager = userManager;
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Logout()
    {
        await _signInManager.SignOutAsync();
        _logger.LogInformation("User logged out.");
        return RedirectToPage("./Index");
    }
}

我正在尝试以这种方式获取 id：

ApplicationUser a = new ApplicationUser();
        CR.FuncionarioId =  a.Id;

但是他返回给我一个完全不同的身份，为什么会这样？我使用身份。然后当我使用 a.Id 时，我会立即每隔一小时，即使是同一个用户，也会带来不同的 Id，并且不会带来 AspnetUsers 表中注册的 Id。

我需要获取用户ID的页面代码：

protected UserManager<ApplicationUser> UserManager { get; set; }
    public RecebimentoModel(CronoParque.Model.ApplicationDbContext context)
    {
        _context = context;
    }
    [BindProperty]
    public string Message { get; set; }
    [BindProperty]
    public ContasReceberViewModel ContasReceberVM { get; set; }



    public async Task<IActionResult> OnPost()
    {
        if (ModelState.IsValid)
        {
            var CR = _context.ContasReceber.Find(ContasReceberVM.ContasReceber.Id);
            CR.Quitado = true;
            CR.ValorPago = Convert.ToDecimal(ContasReceberVM.ContasReceber.ValorPago.ToString().Replace(",","."));
            CR.FormaPagamento = ContasReceberVM.ContasReceber.FormaPagamento;
            CR.DataPagamento = DateTime.Now;
            CR.FuncionarioId = UserManager.GetUserId(HttpContext.User);
            await _context.SaveChangesAsync();
            Message = "Pagamento Realizado com Sucesso!";

            return RedirectToPage("Index");
        }
        return RedirectToPage();
    }

Answer 1

var user = _userManager.GetUserAsync(User);
var id = user.Result.Id;

在你的函数中试试这个，它应该可以工作:)
