The earliest safe hook to get post information is the template_redirect hook. All the hooks in question runs before WordPress has setup postdata, so any post info are still unavailable at that point.
The globals like $wp_query and $post will still contain no data, that is why your efforts returns nothing.
EDIT
Extra info as per comment by @TheDeadMedic
Actually
wpis an earlier, still-safe hook – just make sure to useget_queried_object()instead of relying on$postglobal
