终止脚本后通过APIlity连接到Google Adwords时出错。为什么?

$apilityUser->getManagersClientAccounts()

有什么想法吗?

require_once('apility/apility.php');
$apilityUser = new APIlityUser(
 $email,
 $password,
 $client_email,
 $developer_token,
 $application_token
);

# get all of the accounts (IT DIES HERE)
if(!$emailAccounts = $apilityUser->getManagersClientAccounts()){
 fwrite($STDERR, '** ERROR ** There was an error while trying to connect to the partner!'."\n");
 fclose($STDERR);
 exit;
}
