Openid - User details after authentication - perl

Question

I am trying to use Catalyst::Authentication::Credential::OpenID to authenticate users from Google.
Once authentication is successful, I get a Catalyst::Plugin::Authentication::User::Hash object as my user.
If users are logging in for the first time in my application, I want to get details of user from OpenID provider and store them in my DB.
This is to ease the process of registration, I want as much details from OpenID as possible.
But at least first name, last name, email etc..
But I am not able to achieve it. As an example, if I call, I get exception saying method *url,display * are not defined.
$c->user->url
$c->user->display
Any help in sorting it out is helpful.

Answer 1

After reading the Catalyst manual a number of times and getting some clue from Catalyst mailing lists, I came to know that we have to use extensions.
Because we will be using a number of different realms, I used progressive class.
Here is sample configuration used in my app, currently supporting only openID.
This uses Simple Registration Schema for OpenID Attribute Exchange defined at
http://www.axschema.org/types/
'Plugin::Authentication' => {
default_realm => 'progressive',
realms => {
progressive => {
class => 'Progressive',
realms => [ 'openid' ],
},
openid => {
credential => {
class => "OpenID",
store => {
class => "OpenID",
},
consumer_secret => "Don't bother setting",
ua_class => "LWP::UserAgent",
# whitelist is only relevant for LWPx::ParanoidAgent
ua_args => {
whitelisted_hosts => [qw/ 127.0.0.1 localhost /],
},
extensions => [
'http://openid.net/srv/ax/1.0' => {
mode => 'fetch_request',
'type.nickname' => 'http://axschema.org/namePerson/friendly',
'type.email' => 'http://axschema.org/contact/email',
'type.fullname' => 'http://axschema.org/namePerson',
'type.firstname' => 'http://axschema.org/namePerson/first',
'type.lastname' => 'http://axschema.org/namePerson/last',
'type.dob' => 'http://axschema.org/birthDate',
'type.gender' => 'http://axschema.org/person/gender',
'type.country' => 'http://axschema.org/contact/country/home',
'type.language' => 'http://axschema.org/pref/language',
'type.timezone' => 'http://axschema.org/pref/timezone',
required => 'nickname,fullname,email,firstname,lastname,dob,gender,country',
if_available => 'dob,gender,language,timezone',
}
],
},
}
}
},
