扩展IdentityRole和IdentityUser

Question

我正在使用ASPNet Identity在我的Web应用程序中实现安全性.

有一个要求,我需要扩展IdentityRole和IdentityUser.

这是扩展IdentityUser的代码.

public class ApplicationUser : IdentityUser
{
    public virtual User  User { get; set; }
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("name=CoreContext")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<IdentityUser>()
            .ToTable("AspNetUsers");
        modelBuilder.Entity<ApplicationUser>()
            .ToTable("AspNetUsers");
    }
}

我唯一的问题是IdentityRole

要扩展用户,请更新您的ApplicationUser班级(位于IdentityModels.cs)

public class ApplicationUser : IdentityUser
{
    public async Task<ClaimsIdentity> 
        GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        var userIdentity = await manager
            .CreateIdentityAsync(this, 
                DefaultAuthenticationTypes.ApplicationCookie);
        return userIdentity;
    }

    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }

    // Use a sensible display name for views:
    [Display(Name = "Postal Code")]
    public string PostalCode { get; set; }

}

要扩展角色,请创建一个类 ApplicationRole.cs

public class ApplicationRole : IdentityRole
{
    public ApplicationRole() : base() { }
    public ApplicationRole(string name) : base(name) { }
    public string Description { get; set; }
}

并在IdentityConfig.cs文件中添加类:

public class ApplicationRoleManager : RoleManager<ApplicationRole>
{
    public ApplicationRoleManager(
        IRoleStore<ApplicationRole,string> roleStore)
        : base(roleStore)
    {
    }
    public static ApplicationRoleManager Create(
        IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
    {
        return new ApplicationRoleManager(
            new RoleStore<ApplicationRole>(context.Get<ApplicationDbContext>()));
    }
}

现在清除旧数据库,运行应用程序并注册用户.它将在AspNetUsers表中创建另外3个字段(Address,City,State),并在AspNetRoles表中再创建一个字段(Description).而已.

您可以像继承 IdentityUser 一样从应用程序中继承 IdentityRole。为什么需要扩展 IdentityRole？请查看以下文章，其中详细解释了您要执行的操作http://typecastexception.com/post/2014/02/13/ASPNET-MVC-5-Identity-Extending-and-Modifying-Roles。 ASPX
