将 Identity 2.0 函数移至存储库类

我在我的应用程序中使用 Identity 2.0，并希望将数据功能移动到存储库层，例如以下代码：

    public class ApplicationDbInitializer : DropCreateDatabaseIfModelChanges<ApplicationDbContext> {
    protected override void Seed(ApplicationDbContext context) {
        InitializeIdentityForEF(context);
        base.Seed(context);
    }

    //Create [email protected] with password=Admin@123456 in the Admin role        
    public static void InitializeIdentityForEF(ApplicationDbContext db) {
        var userManager = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();
        var roleManager = HttpContext.Current.GetOwinContext().Get<ApplicationRoleManager>();

现在的问题是HttpContext不存在于存储库层中，您必须将其传递到该层。但即使您这样做，电话也应该来自Web层。但你不想包括userManager在对其他层的每次调用中。有什么解决办法吗？

我找到了在存储库层创建用户管理器的方法：

            var roleStore = new RoleStore<IdentityRole>(context);
            var roleManager = new RoleManager<IdentityRole>(roleStore);
            var userStore = new UserStore<ApplicationUser>(context);
            var userManager = new UserManager<ApplicationUser>(userStore);               
            var user = new ApplicationUser { UserName = "sallen" };

            userManager.Create(user, "password");                    
            roleManager.Create(new IdentityRole { Name = "admin" });
            userManager.AddToRole(user.Id, "admin");
