Question

我是ASP.NET Core的新手，我使用Identity Core创建了一个使用Asp.Net Core 2.2 + EF的应用程序来创建注册页面，运行该应用程序并引入了一些测试数据后，出现此错误（密码）：

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（我的列仅是“ EmailAddress”和“ Password”）

帐户控制器（忽略LOGIN方法）：

    {
        private readonly UserManager<ApplicationUser> _userManager;
        private readonly SignInManager<ApplicationUser> _signInManager;

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

        [HttpGet]

        public IActionResult Login()

            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]

        {
            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

在脚手架Identity（在Visual Studio中单击“个人用户帐户”）时，它将为您生成模型。您需要在该模型上运行迁移。这将创建AspNet *表，其中将包含您缺少的列。看起来您是手动创建了这些表，没有Microsoft Identity期望的列

SQL示例：无效的列名称“ NormalizedUserName”
