ASP MVC5用户身份抽象

问题描述

我想建立默认身份2提供的N-轮胎的Web应用程序。所以，我的数据层包含模型定义纯C＃类，没有任何externad依赖。但是，这是不可能不增加AspNet.Identity参考了一些类，我的应用程序用户联系起来。

I want to build N-tire web application with default Identity 2 provider. So, my Data layer contains pure c# classes with model definition, without any externad dependency. But it is impossible to link some classes to my Application User without adding AspNet.Identity reference.

我试图让用户类的接口：

I have tried to make an interface of User class:

public interface ISystemUser
{
    string Id { get; set; }
    string Title { get; set; }
}

public class Place
{
    public int Id { get; set; }
    public string Address { get; set; }

    public ISystemUser User { get; set; }
}

和基础设施层实现替代它：

And in Infrastructure layer substitute it with implementation:

public class ApplicationUser : IdentityUser, ISystemUser
{
    public string Title { get; set; }
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext() : base("DefaultConnection", throwIfV1Schema: false)
    {
    }

    public DbSet<Place> Places { get; set; }
}

但实体框架没有建立实体之间的关系。

But entity framework does not creates relation between entities.

有没有'正确'的方式就实现这个或者是necesarry添加引用？

Is there any 'right' way do implement this or it is necesarry to add reference?

推荐答案

有一个变通方法，这在我看来是pretty难看，但工作。

There's a workaround, which is pretty ugly in my opinion but works.

您将需要2类，一为用户，另一个是 ApplicationUser 。 ApplicationUser 必须具有用户的所有属性。像这样的：

You will need 2 classes, one for the User and another for the ApplicationUser. ApplicationUser must have all properties of User. Like this:

//Domain Layer
public class User
{
     public string Id { get; set; }
     public string Title { get; set; }
}

//Infrastructure Layer
public class ApplicationUser
{
     public string Title { get; set; }
}

现在，关键是映射用户类的 ApplicationUser 类的同桌。像这样的：

Now, the trick is mapping the User class to the same table of the ApplicationUser class. Like this:

public class UserConfig : EntityTypeConfiguration<User>
{
    public UserConfig()
    {
        HasKey(u => u.Id);

        ToTable("AspNetUsers");
    }
}
