Zend Gmail Oauth: How to get authenticated user profile? - zend-framework

Question

I am using Zend Gmail Oauth 1.0 for implementing login with Gmail feature.
After successful authentication, how can I get authenticated user's profile, specifically user's unique gmail id? Here is the code:
$THREE_LEGGED_SCOPES = array('https://mail.google.com/',
'https://www.google.com/m8/feeds');
$options = array(
'requestScheme' => Zend_Oauth::REQUEST_SCHEME_HEADER,
'version' => '1.0',
'consumerKey' => $THREE_LEGGED_CONSUMER_KEY,
'consumerSecret' => $THREE_LEGGED_CONSUMER_SECRET_HMAC,
'callbackUrl' => getCurrentUrl(),
'requestTokenUrl' => 'https://www.google.com/accounts/OAuthGetRequestToken',
'userAuthorizationUrl' => 'https://www.google.com/accounts/OAuthAuthorizeToken',
'accessTokenUrl' => 'https://www.google.com/accounts/OAuthGetAccessToken'
);
if ($THREE_LEGGED_SIGNATURE_METHOD == 'RSA-SHA1') {
$options['signatureMethod'] = 'RSA-SHA1';
$options['consumerSecret'] = new Zend_Crypt_Rsa_Key_Private(
file_get_contents(realpath($THREE_LEGGED_RSA_PRIVATE_KEY)));
} else {
$options['signatureMethod'] = 'HMAC-SHA1';
$options['consumerSecret'] = $THREE_LEGGED_CONSUMER_SECRET_HMAC;
}
$consumer = new Zend_Oauth_Consumer($options);
/**
* When using HMAC-SHA1, you need to persist the request token in some way.
* This is because you'll need the request token's token secret when upgrading
* to an access token later on. The example below saves the token object
* as a session variable.
*/
if (!isset($_SESSION['ACCESS_TOKEN'])) {
if (!isset($_SESSION['REQUEST_TOKEN'])) {
// Get Request Token and redirect to Google
$_SESSION['REQUEST_TOKEN'] = serialize($consumer->getRequestToken(array('scope' => implode(' ', $THREE_LEGGED_SCOPES))));
$consumer->redirect();
} else {
// Have Request Token already, Get Access Token
$_SESSION['ACCESS_TOKEN'] = serialize($consumer->getAccessToken($_GET, unserialize($_SESSION['REQUEST_TOKEN'])));
header('Location: ' . getCurrentUrl(false));
exit;
}
} else {
// Retrieve mail using Access Token
$accessToken = unserialize($_SESSION['ACCESS_TOKEN']);
}

Answer 1

near as I can tell you can't.
Gmail doesn't have an api just a read only feed.
However if you want that feed the scope url is:
https://mail.google.com/mail/feed/atom/
There are some api's for working with gmail accounts in the context of Google Apps.
