Hello,

I have a strange problem using OpAuth's Facebook strategy.

The strategy works correctly, I can connect via Facebook, but sometime I get this warning:

Warning (2): file_get_contents(https://graph.facebook.com/oauth/access_token?client_id=xxxxxx&client_secret=xxxxxxxx&redirect_uri=http%3A%2F%2Fdev.example.com%2Fauth%2Ffacebook%2Fint_callback&code=AQD5Rkdrhw4J_VRxH72N4R3eWUTO_ItVnY7X3EvQ-f2hAiQboKPv4IHowpk4AU6JJX6wFUc0PnaaItYbeVKtm9uQVWdQdmgXFz47aNI5EtmP_QT8RJIfU35nmhSLzSSE9aH3NZBm0RngUeEyq8-hLOyyhUDZy1-qGZaWyBdzZ3p6aIF193y6TuOxfjYvZfaiz1BEY35HPASCvqb_u9fooOuJIqBCo3qtbS5wgwPbcD6dqE0k3D0WfPJCskYg3KfHYhdbGej1w8fzDJrRvpvpNrWPXw03-m2-Xauj3CtQLO5xxBmfbCRV2keonrg330uIHyk): failed to open stream: HTTP request failed!

Facebook has deprecated the username in the new version 2.0 of the Graph Api, so Opauth is throwing an error Invalid response, missing required parameters.

https://developers.facebook.com/docs/apps/changelog

If we try to connect for the second time using Opauth for Facebook (when we already connected), to extend access token. Facebook won't return expires value.

FacebookStrategy.php:76 will return an error because expires is not set in results

Hello...

I have encountered this problem while using Opauth Facebook.

I cloned this repository into the Strategy folder just like what is instructed in README file.

However, the Facebook folder is seemed to be ignored by git. I was not able to push it into my project. I tried checking gitignore files, but it is not included in gitignore.

Can anyone help me regarding this issue? Thank you so much in advance!

Some people have a middle_name, like me.

First name: Kees middle name: van Last name: Dieren

When I login using Facebook, the 'info' hash contains:

        [info] => Array
            (
                [name] => Kees van Dieren
                [image] => ...
                [nickname] => ....
                [first_name] => Kees
                [last_name] => Dieren
                [urls] => Array
                    (
                        [facebook] => ...
                    )

            )

The middle_name is not present in info.

Solutions could be:

• add a middle_name key to info hash
• add middle_name as suffix to last name, e.g. making last_name 'van Dieren'

API 2.12 will be retired soon. We compared responses from Facebook using API 2.12 and API 6.0 (the latest version) ==> We found no differences in the responses.

Sometimes Facebook send errors without 'error_message', as result we have messages in the logs like this: PHP Notice: Undefined index: error_message in /var/www/website/vendor/opauth/facebook/FacebookStrategy.php on line 59

The FacebookStrategy::int_callback() method fails when there is an error as the response keys are still at the old API. This concerns v0.3 of this package. PR ahead.

In the functionprivate function me it´s necessary put other parameter to get the email

$me = $this->serverGet('https://graph.facebook.com/me', array('access_token' => $access_token,'fields' => 'id,name,email' ), null, $headers);

I have upgraded OAuth version 2.0 in my local repo as per the facebook doc https://developers.facebook.com/docs/apps/upgrading and its works fine for me. @uzyn please review and merge this PR.
