Why don't sessions work in Services?

Question

Laravel

public function boot()
    {
        // Задаеться роль гостя, если он не авторизован
        if(!Session::has('id_user')){
            Session::put('role', 'guest');
        }

        // Глобальная переменная о пользователе
        $myInfo = Users::find(Session::get('id_user'));
        view()->share('userInfo', $myInfo);

    }

If you enter the user id itself into find, then everything works fine, but it refuses with sessions, why, how to fix it?

Answer 1

The session is started from the middleware during the request/response. Starting, if I'm not mistaken, with Laravel 5.2.

The boot method starts earlier, which means it has no access to sessions. And this is quite logical, because, for example, there cannot be sessions in the CLI, which means that it makes no sense to launch and use them in the provider. It makes sense to register the view composer, because it resolves directly during the display of the view, which means that sessions may well already be there.
