如何获取ASP.NET Core MVC中最近登录的用户的列表

Question

我想获取最近登录的用户的列表，我如何获取最近登录的asp.net core MVC中的用户列表？

Answer 1

您可以创建模型类：

 public class LoginEntry
 { 
      [Key]
      public string EntryID { get; set; }
      public string UserID { get; set; }
      public ApplicationUser User { get; set; } //represents the user who was logged
      public DateTime? TimeOfLastLogin { get; set; } //time when the user logged last time
  }

因此，您需要在用户记录时进行输入的一些服务：

public class LoginEntryService
{
  public void DoEntry(ApplicationUser user)
  {
   var entry = dbcontext.LoginEntries.SingleOrDefault(e => e.UserID == userID);
   if (entry == null) //if Entry for the user does not exist then create it
       entry = new LoginEntry() {UserID = user.ID};
   entry.TimeOfLastLogin = DateTime.UtcNow; //update the last login time
   if (entry.ID == null)
       dbcontext.LoginEntries.Add(entry);
   dbcontext.SaveChanges();
  }
}

用户从登录中登录时，您可以调用DO0方法，例如，控制器或用户存储库实例
