Sql 异常：无效的列名“NormalizedUserName

Question

我是 asp.net core 的新手，我使用 Identity Core 使用 Asp.Net Core 2.2 +EF 创建了一个应用程序来创建注册页面，在运行该应用程序并引入一些测试数据（电子邮件、密码）后出现此错误：

SqlException: Invalid column name 'NormalizedUserName'.
              Invalid column name 'AccessFailedCount'.
              Invalid column name 'ConcurrencyStamp'.
              Invalid column name 'Email'.
              Invalid column name 'EmailConfirmed'.
              Invalid column name 'LockoutEnabled'.
              Invalid column name 'LockoutEnd'.
              Invalid column name 'NormalizedEmail'.
              Invalid column name 'NormalizedUserName'.
              Invalid column name 'PasswordHash'.
              Invalid column name 'PhoneNumber'.
              Invalid column name 'PhoneNumberConfirmed'.
              Invalid column name 'SecurityStamp'.
              Invalid column name 'TwoFactorEnabled'.
              Invalid column name 'UserName'.

我创建了一个表，但没有像上面那样命名的列（我的列只有“EmailAddress”和“Password”）

帐户控制器（忽略 LOGIN 方法）：

{
    public class AccountController : Controller
    {
        private readonly UserManager<ApplicationUser> _userManager;
        private readonly SignInManager<ApplicationUser> _signInManager;

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

        [HttpGet]

        [HttpGet]

        public IActionResult Login()
        {
            return View();
        }
        [HttpPost]

        public async Task<IActionResult> Login(LoginViewModel vm)//model binding
        {
            //date din vm sunt bune:
            if(ModelState.IsValid)
            {
                var result = await _signInManager.PasswordSignInAsync(vm.Email, vm.Password, vm.RememberMe, false);//folosit para pt IsPersistent(BOOL)
                if(result.Succeeded)
                {
                    return RedirectToAction("Privacy", "Home");
                }
                ModelState.AddModelError("","Invalid Login. Please Check your username/email or password.");
                return View(vm);
            }
            return View(vm);
        }

        public IActionResult Register()
        {
            return View();
        }

        [HttpPost]

        public async Task<IActionResult> Register(RegisterViewModel vm)//model binding
        {
            if (ModelState.IsValid)
            {

                var user = new ApplicationUser { UserName = vm.Email, Email = vm.Email };
                var result = await _userManager.CreateAsync(user, vm.Password);

                if (result.Succeeded)
                {
                    await _signInManager.SignInAsync(user, false);
                    return RedirectToAction("Index", "Home");

                }
                else
                {
                    foreach (var error in result.Errors)
                    {
                        ModelState.AddModelError("", error.Description); //erori de inregistrare in cont
                    }//iterare prin fiecare eroare

                }
            }
            return View(vm);
        }
    }
}

Answer 1

@AlexGodo 我知道这个主题很旧，但它可能会帮助那些将 ASP.NET 项目移动到 ASP.NET Core 的人，这些人不想使用迁移而只想连接到现有AspNet*表。要解决缺少列的问题，只需将它们添加到AspNetUsers表中（例如通过 SSMS）：

我缺少 4 列，其中NormalizedUserName重要的一列（随机数据类型 - TBC）：

NormalizedUserName nvarchar(256), null
NormalizedEmail nvarchar(256), null
LockoutEnd datetime, null
ConcurrencyStamp nvarchar(256), null

为了能够登录，我运行了更新来填充 NormalizedUserName 列，如下所示：

update AspNetUsers
   set NormalizedUserName = UPPER(Email)
where NormalizedUserName is null

注意：通过 ASP.NET Core 网站登录后，PasswordHash栏目条目发生变化，因此无法再通过旧网站登录。（如果需要，最好对此列进行备份。）

希望这可以帮助。
