ASP.NET MVC 5 在 Oracle 数据库中存储身份用户

Question

我是开发 ASP.NET 应用程序的新手，我开始了一个新项目，我正在使用带有 ODP 和 OLAC 插件的 Oracle DB。我设置了我的连接字符串，我可以在服务器资源管理器下看到数据库。

现在我也希望将身份用户存储在我的数据库中，但我现在找不到他们的存储位置。 app_data 文件夹是空的，任何地方都没有.mdf 文件，我的连接字符串是Oracle 连接字符串；但是当我设置 IdentityDBContext 以使用我自己的连接字符串时，我收到一条错误消息 “实体类型 ApplicationUser 不是当前上下文模型的一部分。” 我使用的是数据库优先方法：

这是为我的数据库上下文自动生成的代码：

public partial class ActivoContext : DbContext
{
    public ActivoContext()
        : base("name=ActivoContext")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        throw new UnintentionalCodeFirstException();
    }
......

这是项目生成的Identity码，我只是改了连接字符串：

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("name=ActivoContext", throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

web.config 文件：

<connectionStrings>
  <add name="ActivoContext" connectionString="metadata=res://*/Activo.csdl|res://*/Activo.ssdl|res://*/Activo.msl;provider=Oracle.ManagedDataAccess.Client;provider connection string=&quot;DATA SOURCE=localhost:1521/xe;PASSWORD=activos;USER ID=ACTIVOS&quot;" providerName="System.Data.EntityClient" />
</connectionStrings>

编辑 所以我意识到问题在于使用相同的连接字符串有两个不同的上下文。正因为如此，只有一个出现，而另一个不起作用：自动生成的 db-first ActivoContext 出现，而​​ ApplicationDbContext 没有。我应该如何将这两者合并或使它们一起工作？我无法修改 DbContext 导致其自动生成...

终于让 Identity 2.0 与我的 Oracle 数据库一起工作。这是我所做的：

如果您不想对默认 IdentityUser 进行任何更改（例如，如果您可以使用 char ID 而不是 int 或 long）并且只想要现有 Oracle 架构上的表，则以下步骤有效.

1) 在 Oracle 上创建身份表。您可以根据需要更改表名，只需确保包含 Identity 使用它所需的列。您还可以在您的应用程序中添加您可能需要的任何额外列（最初在 Devart 上找到的脚本，我将其复制到一个要点以防 URL 中断）：

要点here

2) 如果您使用的是 EDMX 文件，则需要添加一个新的连接字符串，因为自动生成的连接字符串不起作用，您需要一个标准连接字符串。尝试遵循此模板：

<add name="IdentityContext" connectionString="Data Source=localhost:1521/xe;PASSWORD=password;USER ID=username;" providerName="Oracle.ManagedDataAccess.Client" />

3) 告诉您的 ApplicationDbContext 使用您的新 connectionString

public ApplicationDbContext()
: base("IdentityContext", throwIfV1Schema: false)
{
}

4) 告诉 Identity 使用您现有的架构和表。在 IdentityModels.cs 中的 ApplicationDbContext 定义中添加此方法：

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder); // MUST go first.

modelBuilder.HasDefaultSchema("YOUR_SCHEMA"); // Use uppercase!

modelBuilder.Entity<ApplicationUser>().ToTable("AspNetUsers");
modelBuilder.Entity<IdentityRole>().ToTable("AspNetRoles");
modelBuilder.Entity<IdentityUserRole>().ToTable("AspNetUserRoles");
modelBuilder.Entity<IdentityUserClaim>().ToTable("AspNetUserClaims");
modelBuilder.Entity<IdentityUserLogin>().ToTable("AspNetUserLogins");
}

5) 重建，就是这样！

您可以使用此脚本在 Oracle DB 中正确创建身份表

如下所示修改 ConnectionString

<add name="DBContext" connectionString="Data Source=AAAA:1521/AA;PASSWORD=AAAA;USER ID=AAAA;" providerName="Oracle.ManagedDataAccess.Client" />

然后像这样修改你的 OnModelCreating 方法

`

protected override void OnModelCreating(DbModelBuilder modelBuilder)  
     {  
       base.OnModelCreating(modelBuilder);  
       modelBuilder.HasDefaultSchema("AAAAA");
       modelBuilder.Entity<ApplicationUser>()  
       .ToTable("ASPNETUSERS").Property(p => p.UserName).HasColumnName("USERNAME");  
       modelBuilder.Entity<ApplicationUser>()

       .ToTable("ASPNETUSERS").Property(p => p.LockoutEndDateUtc).HasColumnName("LOCKOUTENDDATEUTC");  
       modelBuilder.Entity<ApplicationUser>()  
       .ToTable("ASPNETUSERS").Property(p => p.TwoFactorEnabled).HasColumnName("TWOFACTORENABLED");  
       modelBuilder.Entity<ApplicationUser>()  
       .ToTable("ASPNETUSERS").Property(p => p.PhoneNumberConfirmed).HasColumnName("PHONENUMBERCONFIRMED");  
       modelBuilder.Entity<ApplicationUser>()  
       .ToTable("ASPNETUSERS").Property(p => p.PhoneNumber).HasColumnName("PHONENUMBER");  
       modelBuilder.Entity<ApplicationUser>()  
       .ToTable("ASPNETUSERS").Property(p => p.SecurityStamp).HasColumnName("SECURITYSTAMP");

       .ToTable("ASPNETUSERS").Property(p => p.PasswordHash).HasColumnName("PASSWORDHASH");  
       modelBuilder.Entity<ApplicationUser>()  
       .ToTable("ASPNETUSERS").Property(p => p.EmailConfirmed).HasColumnName("EMAILCONFIRMED");  
       modelBuilder.Entity<ApplicationUser>()  
       .ToTable("ASPNETUSERS").Property(p => p.Email).HasColumnName("EMAIL");  
       modelBuilder.Entity<ApplicationUser>()  
       .ToTable("ASPNETUSERS").Property(p => p.Id).HasColumnName("ID");  
       modelBuilder.Entity<IdentityUserRole>()  
       .ToTable("ASPNETUSERROLES").Property(p => p.RoleId).HasColumnName("ROLEID");  
       modelBuilder.Entity<IdentityUserRole>()  
       .ToTable("ASPNETUSERROLES").Property(p => p.UserId).HasColumnName("USERID");  
       modelBuilder.Entity<IdentityUserLogin>()  
       .ToTable("ASPNETUSERLOGINS").Property(p => p.UserId).HasColumnName("USERID");  
       modelBuilder.Entity<IdentityUserLogin>()  
       .ToTable("ASPNETUSERLOGINS").Property(p => p.ProviderKey).HasColumnName("PROVIDERKEY");  
       modelBuilder.Entity<IdentityUserLogin>()  
       .ToTable("ASPNETUSERLOGINS").Property(p => p.LoginProvider).HasColumnName("LOGINPROVIDER");  
       modelBuilder.Entity<IdentityUserClaim>()  
       .ToTable("ASPNETUSERCLAIMS").Property(p => p.Id).HasColumnName("ID");  
       modelBuilder.Entity<IdentityUserClaim>()  
       .ToTable("ASPNETUSERCLAIMS").Property(p => p.UserId).HasColumnName("USERID");  
       modelBuilder.Entity<IdentityUserClaim>()  
       .ToTable("ASPNETUSERCLAIMS").Property(p => p.ClaimType).HasColumnName("CLAIMTYPE");  
       modelBuilder.Entity<IdentityUserClaim>()

       modelBuilder.Entity<IdentityRole>()

       modelBuilder.Entity<IdentityRole>()  
       .ToTable("ASPNETROLES").Property(p => p.Name).HasColumnName("NAME");  
     }

这在我的项目中运行良好。
