Question

Ciao

我正在使用IdentityServer和ASP.NET Identity从事.NET Core 2.2项目。

我有以下实体：

ExtraDatas表

+----+-------------+
| Id | Description |
+----+-------------+
| 1  | A           |
| 2  | B           |
| 3  | C           |
+----+-------------+

AspNetRoles

+----+-------+----------------+------------------+
| Id | Name  | NormalizedName | ConcurrencyStamp |
+----+-------+----------------+------------------+
|  1 | Admin | Admin          | [NULL]           |
|  2 | User  | User           | [NULL]           |
+----+-------+----------------+------------------+

RoleExtraDatas

+-------------+-----------------+
| RoleId (FK) | ExtraDataId (FK)|
+-------------+-----------------+
|           1 |               1 |
|           1 |               3 |
|           2 |               2 |
+-------------+-----------------+

由以下类代表：

public class ExtraData
{
    [Key, Required]
    public int Id { get; set; }

    [Required, MaxLength(128)]
    public string Description { get; set; }

    public virtual ICollection<RoleExtraData> ExtraDatas { get; set; }
}

public class ApplicationRole: IdentityRole
{
    public virtual ICollection<RoleExtraData> ExtraDatas { get; set; }
}

public class RoleExtraData
{
    public string RoleId { get; set; }
    public ApplicationRole Role { get; set; }
    public int ExtraDataId { get; set; }
    public ExtraData ExtraDatas { get; set; }
}

在我的 Startup.cs 中，我已经配置了ASP.NET Identity，并传递了我的 ApplicationRole 类的引用：

services.AddIdentity<IdentityUser, ApplicationRole>()
    .AddEntityFrameworkStores<MyIdentityDbContext>()
    .AddDefaultTokenProviders();

在具有依赖项注入的服务内部，我获得了 UserManager 和 RoleManager 属性，但是当我尝试执行此代码时， role.ExtraDatas 是空：

IdentityUser user = userManager.GetUserAsync(context.Subject).Result;
Task<IList<string>> roleList = userManager.GetRolesAsync(user);

foreach (var roleId  in roleList.Result)
{
    ApplicationRole role = roleManager.FindByNameAsync(roleId).Result;

    // the property role.ExtraDatas is empty
}

如何解决此问题？

非常感谢

如何在ASP.NET Core Identity中扩展角色对象？
