[felix-kot]

i try retrieve user photos on my site.
my code on PHP:

$oauthOptions = array(
            'requestScheme'        =>
Zend_Oauth::REQUEST_SCHEME_HEADER,
            'version'              => '1.0',
            'consumerKey'     => 'XXXXXXX',
            'consumerSecret'  => 'SSSSSSSSSS',
            'signatureMethod'      => 'HMAC-SHA1',
            'callbackUrl'          => 'http://mysite/oauth',
            'requestTokenUrl'      => 'https://www.google.com/accounts/
OAuthGetRequestToken',
            'userAuthorizationUrl' => 'https://www.google.com/accounts/
OAuthAuthorizeToken',
            'accessTokenUrl'       => 'https://www.google.com/accounts/
OAuthGetAccessToken'
        );

        $consumer = new Zend_Oauth_Consumer($oauthOptions);
        $token    = null;

        if ($_SESSION['GOOGLE_ACCESS_TOKEN']){
            $token = unserialize($_SESSION['GOOGLE_ACCESS_TOKEN']);
        } else if(isset($_GET['oauth_token'])) {
            $token = $consumer->getAccessToken( $_GET,
 
unserialize($_SESSION['GOOGLE_REQUEST_TOKEN']));
            $_SESSION['GOOGLE_ACCESS_TOKEN'] = serialize($token);
        }

        if(!$token) {
            $token = $consumer->getRequestToken(array( 'scope' =>
'https://picasaweb.google.com/data/'));
            $_SESSION['GOOGLE_REQUEST_TOKEN'] = serialize($token);
            $consumer->redirect();
        } else {
            die(var_dump($token));
        }
