Question

为了支持天安/公司，我在ASP MVC 5，Identity 2.2角色管理中添加/扩展了一个新属性到名为OrgId 的Login()，我添加了相应的或者对其他一些表格looked here but no answers

在用户UserSession和ApplicationUser user = System.Web.HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>().FindById(System.Web.HttpContext.Current.User.Identity.GetUserId());

期间

如何缓存，配置＆amp;检索OrgId，以便我可以为组织特定记录执行DBConext过滤/ CRUD ？
建议：最好将其保存在Claims，FormsToken或Session中如何在会话中设置tenanId上下文？

我知道如何获得用户，但不知道扩展的组织

您的自定义用户类应如下所示：

public class CustomizedUser : IdentityUser
    {
        public int OrgId {get; set;}
        public DateTime JoinDate { get; set; }
        //...
        // and other simple fields

       //Fields related to other tables
        public virtual ICollection<Article> Articles { get; set; } = new List<Article>();
      //...      
}

您的CustomizedApplicationDbContext类

public class CustomizedApplicationDbContext : IdentityDbContext<CustomizedUser>, IApplicationDbContext
{
    public CustomizedApplicationDbContext()
        : base("DefaultConnection", throwIfV1Schema: false)
    {
    }

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

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        //your entity configurations go here if you have any

        base.OnModelCreating(modelBuilder);
    }

    //These fields are neccessary in order to maintain the power of base class
    public DbChangeTracker Changetracker => base.ChangeTracker;
    public Database DatabBase => base.Database;

    //your own dbsets go here except CustomizedUser, because the base class IdentityDbContext<CustomizedUser> handles it
    public IDbSet<Article> Articles { get; set; }
    //...

}

现在，请记住用CustomizedApplicationDbContext替换每个ApplicationDbContext引用，并在代码中使用CustomizedUser引用每个IdentityUser引用（特别是在mvc创建的ManageController中）。

从现在开始，您可以像其他表一样轻松访问用户表：

var db = new CustomizedApplicationDbContext();
var user = db.CustomizedUsers.First(x=> x.OrgId == 10 || Email == "sth@yahoo.com");

要获得当前用户OrgId，您可以使用类似的东西（不查询数据库）：

var currentUserOrgId = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>().FindById(User.Identity.GetUserId()).OrgId;

希望这是有帮助的

您可以在ASP.NET Identity中获取当前用户，如下所示：

ApplicationUser user = System.Web.HttpContext.Current.GetOwinContext()
    .GetUserManager<ApplicationUserManager>()
    .FindById(System.Web.HttpContext.Current.User.Identity.GetUserId());

//If you use int instead of string for primary key, use this:
ApplicationUser user = System.Web.HttpContext.Current.GetOwinContext()
    .GetUserManager<ApplicationUserManager>()
    .FindById(Convert.ToInt32(System.Web.HttpContext.Current.User.Identity.GetUserId()));

从AspNetUsers表中获取自定义属性：

ApplicationUser user = UserManager.FindByName(userName);
string name = user.Name;

希望这会有所帮助......
