Google Drive PHP SDK 保存无标题文件

我正在使用以下函数来插入文件：

function insertFile($service, $title, $description, $parentId, $mimeType, $filename) {
  $file = new DriveFile();
  $file->setTitle($title);
  $file->setDescription($description);
  $file->setMimeType($mimeType);
  if ($file->parentId != null) {
    $parentsCollectionData = new DriveFileParentsCollection();
    $parentsCollectionData->setId($file->parentId);
    $file->setParentsCollection(array($parentsCollectionData));
  }
  try {
    $datafile = file_get_contents($filename);
    $createdFile = $service->files->insert($file, array(
      'data' => $datafile,
      'mimeType' => $mimeType,
    ));
    print_r($datafile);
  return $createdFile;
  } catch (Exception $e) {
    print "An error occurred: " . $e->getMessage();
  }}

该函数上传文件，但没有标题。它在我的 Google 云端硬盘中创建了一个“无标题”文件。我正在使用 API v2。

打印_r（$文件）：
