I'm having some trouble with Drive SDK. I am trying to get all files from my Google Drive account into my app. I feel like I am doing everything that the Drive SDK documentation tells me to do, but every time I go to grab files, I get an empty array returned ... and no errors. I'm using the SDK as a service account, so the set up is a bit different. My site is running drupal by the way. Here is my code:
1) first off, I build the service (this is the body of a function named buildService():
$key = PATH_TO_KEY_FILE;
if (file_exists($key)) {
try {
$auth = new Google_AssertionCredentials(
SERVICE_ACCOUNT_EMAIL,
array(DRIVE_SCOPE),
$key);
$client = new Google_Client();
$client->setUseObjects(true);
$client->setAssertionCredentials($auth);
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
return new Google_DriveService($client);
}
else{
return "can't find key file';
}
This block is completely fine, I get an object from Google_DriveService
2) the other side, I grab the service object, and attempt to list Drive files:
$parameters = array();
$service = buildService(); //my function from step 1
$files = retrieveAllFiles($service, $parameters);
3) Here is the the retrieveAllFiles function (straight from the SDK documentation):
function retrieveAllFiles($service, $parameters) {
$result = array();
$pageToken = NULL;
do {
try {
if ($pageToken) {
$parameters['pageToken'] = $pageToken;
}
$files = $service->files->listFiles($parameters);
$result = array_merge($result, $files->getItems());
$pageToken = $files->getNextPageToken();
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
$pageToken = NULL;
}
} while ($pageToken);
return $result;
}
As I said, I am getting an empty result returned, no errors, nothing.
Any Ideas as to why my result is empty?
Any help or suggestions are greatly appreciated.
