使用PHP调用的Google驱动程序API返回响应，但不上传图像

感谢您的宝贵时间，

我有这样的代码:

$googleClient = Google::getClient();
$googleClient->setApplicationName("aiesec");
$googleClient->setScopes('Google_Service_Drive::DRIVE);
//$googleClient->setSubject('stivenson.rpm@gmail.com');
$googleClient->setAuthConfig('/opt/lampp/htdocs/aiesec/administration/aiesec-34835b27733e.json');

$service = new 'Google_Service_Drive($googleClient);

$himage = new Image; // only is helper class 
$file = new 'Google_Service_Drive_DriveFile();
$file->setName($attr['names'].' '.$attr['last_names']);
$file->setDescription('Foto de '.$attr['names'].' '.$attr['last_names'].' desde App');
$file->setMimeType('image/'.$himage->getMime($photo));

$createdFile = $service->files->create($file, [
      'data' => file_get_contents($himage->getPath($photo)),
      'mimeType' => 'image/'.$himage->getMime($photo),
      'uploadType' => 'multipart'
    ]);

And I Have this answer
