How can I use it ?

require('Client.php'); require('GrantType/IGrantType.php'); require('GrantType/AuthorizationCode.php');

const CLIENT_ID = 'your client id'; const CLIENT_SECRET = 'your client secret';

const REDIRECT_URI = 'http://url/of/this.php'; const AUTHORIZATION_ENDPOINT = 'https://graph.facebook.com/oauth/authorize'; const TOKEN_ENDPOINT = 'https://graph.facebook.com/oauth/access_token';

$client = new OAuth2\Client(CLIENT_ID, CLIENT_SECRET); if (!isset($_GET['code'])) { $auth_url = $client->getAuthenticationUrl(AUTHORIZATION_ENDPOINT, REDIRECT_URI); header('Location: ' . $auth_url); die('Redirect'); } else { $params = array('code' => $_GET['code'], 'redirect_uri' => REDIRECT_URI); $response = $client->getAccessToken(TOKEN_ENDPOINT, 'authorization_code', $params); parse_str($response['result'], $info); $client->setAccessToken($info['access_token']); $response = $client->fetch('https://graph.facebook.com/me'); var_dump($response, $response['result']); }

How can I add a new Grant Type ?

Simply write a new class in the namespace OAuth2\GrantType. You can place the class file under GrantType. Here is an example :

namespace OAuth2\GrantType;

/**

• MyCustomGrantType Grant Type / class MyCustomGrantType implements IGrantType { /*

  • Defines the Grant Type
  • @var string Defaults to 'my_custom_grant_type'. */ const GRANT_TYPE = 'my_custom_grant_type';

  /**

  • Adds a specific Handling of the parameters
  • @return array of Specific parameters to be sent.
  • @param mixed $parameters the parameters array (passed by reference) */ public function validateParameters(&$parameters) { if (!isset($parameters['first_mandatory_parameter'])) { throw new \Exception('The 'first_mandatory_parameter' parameter must be defined for the Password grant type'); } elseif (!isset($parameters['second_mandatory_parameter'])) { throw new \Exception('The 'seconde_mandatory_parameter' parameter must be defined for the Password grant type'); } } }

call the OAuth client getAccessToken with the grantType you defined in the GRANT_TYPE constant, As following : $response = $client->getAccessToken(TOKEN_ENDPOINT, 'my_custom_grant_type', $params);
