How to create BasePage Model class in Razor Pages ?

Question

User-1042970710 posted

In my application after authentication I store my User object in the session and move to another pages. If the session is null I will divert to Login page.

Here is the Code where I check my Session

 public class IndexModel : PageModel
 {
        public IActionResult OnGet()
        {
            var usersLoginInfo = HttpContext.Session.GetObjectFromJson<UsersLoginInfo>("UserInfo");
           
            if (usersLoginInfo == null)
                return new RedirectToPageResult("/Login");
            else
                return Page();
        }
 }

What I was thinking to make separate class BasePageModel  inherited from PageModel  and then import all my pages from that class i.e BasePageModel  instead of PageModel.

My problem is when I separate the the class and try to override the OnGet method The framework is complaining  that the method is not overridable.  

I want to avoid checking my session in all my pages.... 

Is there any work around?

Thanks.

to override OnGet you need to make it virtual. though I think you have picked a bad design. your authentication logic should be in middleware.
