Re: [Mojolicious] struggling with OAuth(2) from google

[Dan Book]

This looks like a bug in the module. The is_success method returns a
boolean value, not the result (which is returned by $tx->result).

[Mojolicious] struggling with OAuth(2) from google

[iwelch]

dear M experts.  I am again struggling with the OAuth module.  this is 
perhaps because I installed a new ubuntu 18.04.2 machine, and then updated 
Mojolicious to the current version.

first, for anyone else struggling, Mojolicious::Plugin::Web::Auth depends 
on Net::SSLeay, which fails installing.  I believe I fixed this by 
installing `apt install libssl-dev libz-dev`.  I know this is not M's 
fault, but I would suggest that the Auth author stop the install with a 
good instructive error message when these two libraries are not detected.  
grrr


second, my M code is still the same as before, but now it is dying with a 
non-informative error message at the point where I had hoped to get my 
Google authentication callback:

*Can't locate object method "headers" via package "1" (perhaps you forgot 
to load "1"?) at 
/usr/local/share/perl/5.26.1/Mojolicious/Plugin/Web/Auth/OAuth2.pm line 
122.*

I believe the callback I am getting from google is:

*http://auth.syllabus.space/auth/google/callback?state=hashcode=hashcode=email+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email+openid=0=g.ucla.edu_state=hashcodes=none*

I am guessing that google encodes the email address in one of the hash 
codes (which I have blanked here).

my relevant (I think) code excerpt that should be called is

package SylSpace::Controller::AuthAuthenticator;
use Mojolicious::Lite;

sub google {
  my ( $self, $access_token, $userinfo ) = @_;
  my $name = $userinfo->{displayName} || $userinfo->{name};
  my $email= $userinfo->{email};

  (defined($email)) or die "no good email.";

  return logandreturn( $self, $email, $name, 'google' );
}

looking at the code, the error comes from

(my $res = $tx->result->is_success ) or do {
return $callback->{on_error}->( $tx->res->body );
};

my $dat = $self->_response_to_hash($res);

...

my $exts = $types->detect( $res->headers->content_type );

could someone please help me?  what could have gone wrong here?
