Sql 异常：列名称“NormalizedUserName”无效

Question

我是 asp.net 核心的新手，我用 Asp.Net Core 2.2 +EF 创建了一个应用程序，使用 Identity Core 创建了一个注册页面，我在运行之后收到了这个错误该应用程序并引入了一些测试数据（电子邮件，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 table，但我的列没有像上面那样命名（我的列只有 "EmailAddress" 和 "Password"）

Answer 1

当您构建 Identity 时（通过单击 visual studio 中的 "individual user account"），它会为您生成模型。您需要运行在 该模型 上进行迁移。这将创建包含您缺少的列的 AspNet* 表。看起来你手动创建了这些表，没有 Microsoft Identity 期望的列

Answer 2

@AlexGodo 我知道这个话题很老了，但它可能会帮助那些将 ASP.NET 项目移动到 ASP.NET Core 的人，他们不想使用迁移，只是连接到现有的 AspNet* tables。要解决缺少列的问题，只需将它们添加到 AspNetUsers table（例如通过 SSMS）：

我缺少 4 列，其中 NormalizedUserName 是重要的一列（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，我运行更新以填充 NormalizedUserName 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栏条目发生变化，因此将无法再通过旧网站登录. （如果需要，最好备份此列。）

希望这对您有所帮助。
