Sql Exeption：无效的列名"规范化用户名"

Question

我是 asp.net 核心新手，我使用身份核心创建了一个使用 Core 2.2 +EF Asp.Net 应用程序来创建注册页面，在运行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，但我没有像上面那样命名我的列(我的只有"电子邮件地址"和"密码"(

Answer 1

> @AlexGodo我知道这个话题已经过时了，但它可能会帮助那些不想使用迁移而只是连接到现有AspNet*表的人 ASP.NET 项目移动到 ASP.NET Core。 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列很重要(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，我运行了更新以填充规范化用户名列，如下所示：

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

注意：通过 ASP.NET 核心网站登录后PasswordHash列条目会发生变化，因此无法再通过旧网站登录。 (如果需要，最好备份此列。

希望这有帮助。

当你搭建基架Identity(通过在 Visual Studio 中单击"个人用户帐户"(时，它会为你生成模型。您需要在该模型上运行迁移。这将创建 AspNet* 表，这些表将包含您缺少的列。 看起来您手动创建了这些表，没有 Microsoft Identity 期望的列
