如何緩存和得到擴展身份，ASPUSER性能在ASP身份2.2

Question

支持tenan /公司，我添加/擴展新的屬性到AspUser Table稱爲OrgId在ASP MVC 5，身份2.2角色管理，我加相應ORGID一些其他表，looked here but no answers

在用戶Login()和UserSession

1. 我怎麼緩存，配置&檢索ORGID，讓我CA n爲組織特定記錄執行DBConext過濾/ CRUD表？
2. 建議：最好將此保存在Claim，FormsToken或Session中 - 如何在會話中設置tenanId上下文？

我知道如何獲得用戶，而不是擴大組織

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

Answer 1

您定製的用戶類別應該是這樣的：

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>(); 
     //...  
} 

而且你CustomizedApplicationDbContext類

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; } 
    //... 

} 

現在，請記住在代碼中使用CustomizedApplicationDbContext和CustomizedUser替換每個ApplicationDbContext引用（特別是在由mvc創建的ManageController中）。

從現在起，您可以輕鬆地訪問用戶表就像其他表：

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

而要獲取當前用戶ORGID，你可以使用這樣的事情（不包括查詢DB）：

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

希望這是有幫助的

你可以在ASP.NET Identity當前用戶，如下圖所示：

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())); 

對於來自AspNetUsers表中獲取自定義屬性：

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

希望這有助於...
