Google Drive API downloadFile getIo Error

Я хочу создать приложение gDrive. Я могу получить DownloadUrl (как строка 'https://doc-0k-68-docs.googleusercontent.com/docs/securesc/gf6salc3nfs5me1dnqgnp4crl90gg593/21kfelc8h3l1qvkgskqacnee2pqjt5es/1343484000000/14678698184812381901/14678698184812381901/0B95t2gVGbZ61Sk0yNlY5TTZObUU?h=16653014193614665626&e=download&gd=true'(длина=251))

Но не могу скачать по этой ссылке. Я думаю, должна быть какая-то авторизация.

я пробую эти функции, я беру здесь

function downloadFile($service, $file) {
  $downloadUrl = $file->getDownloadUrl();
  if ($downloadUrl) {
    $request = new apiHttpRequest($downloadUrl, 'GET', null, null);
    $httpRequest = $service->getIo()->authenticatedRequest($request);
    if ($httpRequest->getResponseHttpCode() == 200) {
      return $httpRequest->getResponseBody();
    } else {
      // An error occurred.
      return null;
    }
  } else {
    // The file doesn't have any content stored on Drive.
    return null;
  }
}

я ошибаюсь

Вызов неопределенного метода apiDriveService ::getIo ()в....

пожалуйста, помогите мне. нигде не могу найти.
