Google authentication - google-authentication

Question

I got a problem on google authenticate, it worked for a month but since a few days I got this error :
Fatal error: Uncaught exception 'apiAuthException' with message
'Invalid token format' in /home/project/html/google/auth/apiOAuth2.php:127 Stack trace:
#0 /home/project/html/google/auth/apiOAuth2.php(89): apiOAuth2->setAccessToken('{? "access_tok...')
#1 /home/project/html/google/apiClient.php(132): apiOAuth2->authenticate(Array)
#2 /home/project/html/hk/connects/google.php(22): apiClient->authenticate()
#3 {main} thrown in /home/project/html/google/auth/apiOAuth2.php on line 127
In apiOAuth2.php I have the code :
$accessToken = json_decode($accessToken, true);
if (! isset($accessToken['access_token']) || ! isset($accessToken['expires_in']) || ! isset($accessToken['refresh_token'])) {
throw new apiAuthException("Invalid token format");
}
I noticed that google doesn't send me the $accessToken['refresh_token'].
It doesn't seem to come from google cause I did a correct connexion on http://stackoverflow.com
Maybe it's cause of my code :
session_start();
$client = new apiClient();
$plus = new apiPlusService($client);
if (!isset($_GET['code'])) {
header('Location: '.$client->createAuthUrl()); // Calls the same page
} else {
$client->authenticate(); // Fails at this level
}
EDIT:
I figured a way to do it, like I don't know what is refresh_token made for I added this line :
if (!isset($accessToken['refresh_token'])) $accessToken['refresh_token'] = 12345678910;
It works for the moment...

There is a new explicit parameter called "access_type" required by the google authentication api to obtain a valid refresh token.
With this parameter you declare that you need offline access to the account and the api provides you a refresh token.
Download the latest google PHP SDK that automatically handles the new required parameter
