Question

我是MVC的新手，正在从事用户身份验证授权。我想用UniqueNumber而不是Email更改用户登录凭据。

我尝试过但是它抛出了这个错误

错误1：最佳重载方法匹配项'Microsoft.AspNet.Identity.Owin.SignInManager.PasswordSignInAsync（string，string，bool，bool）'包含一些无效参数

登录操作

public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }

        // This doesn't count login failures towards account lockout
        // To enable password failures to trigger account lockout, change to shouldLockout: true
        var result = await SignInManager.PasswordSignInAsync(model.UniqueNumber, model.Password, model.RememberMe, shouldLockout: false);
        switch (result)
        {
            case SignInStatus.Success:
                return RedirectToLocal(returnUrl);
            case SignInStatus.LockedOut:
                return View("Lockout");
            case SignInStatus.RequiresVerification:
                return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
            case SignInStatus.Failure:
            default:
                ModelState.AddModelError("", "Invalid login attempt.");
                return View(model);
        }
    }

LoginViewModel

public class LoginViewModel
{

    [Required]
    [Display(Name = "Unique Number")]
    public int UniqueNumber { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [Display(Name = "Remember me?")]
    public bool RememberMe { get; set; }
}

考虑到此问题，可能是以下SO answer的副本：

在致电UniqueNumber时，必须更改用户注册以使用var user = new ApplicationUser { UserName = model.UniqueNumber, Email = model.Email };而不是电子邮件。

是的，正如@Gonzalo Lorieto所说，您必须将UniqueNumber转换为字符串。
