How to pass additional parameters to `under` subroutine in Mojolicious?

Question

I have two routes:

$auth =  $r->under( \&auth );
$auth->get( "/test",   { level => 'user' }  )->to( "C#A1" );
$auth->get( "/secure", { level => 'admin' } )->to( "C#A2" );

I use under to check access level. But when auth subroutine is called it has not yet { level } value. The { level } will be available only at action.

How better pass to &auth function required user level for target route?

Answer 1

I have found answer. I should use stack method:

sub auth {
    ...
    return 1   if $c->match->stack->[-1]{ level } <= $user->level;
}

It contains:

[
  { api => 1, cb => sub { ... } },                     # stash at &auth
  { api => 1, cb => sub { ... }, level => "user" },    # stash at &C#A*
]
