将Identity 2.0函数移动到存储库类

Question

我的应用程序使用identity 2.0，并希望将数据功能移动到存储库层，如以下代码:

    public class ApplicationDbInitializer : DropCreateDatabaseIfModelChanges<ApplicationDbContext> {
    protected override void Seed(ApplicationDbContext context) {
        InitializeIdentityForEF(context);
        base.Seed(context);
    }
    //Create User=[e-mail] 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不在存储库层中，您必须将其传递给该层。但即使这样做，调用也应该来自Web层。但是，您不希望在每次调用其他层时都包含userManager。有解决方案吗?

我找到了在存储库层上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");
