我正在尝试获取存储在Google云端硬盘上的文件的文字内容（word和PDF），但经过大量研究后，我无法找到如何使其发挥作用。我正在使用Drive API，所有身份验证过程都正常。我可以使用API上传和访问文件。
认证后，我使用了GET代码：
$driveService = new Google_Service_Drive($client);
$id = ‘XXXX’;
$content = $driveService->files->get($id);
print_r($content);
我们测试中使用的文件是从API上传的“application / vnd.google-apps.document”。 它返回一个带有一些文件信息的对象但字段“webViewLink”e“webContentLink”是空白的，我真的不知道为什么？ 对象返回：
Google_Service_Drive_DriveFile Object

我也尝试过以不同的方式，使用EXPORT方法。这是我使用的代码：
$content = $driveService->files->export($id, 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', array(
'alt' => 'media' ));
print_r($content);
它返回一个不同的对象，但我不知道是否可以使用它来获取文件内容。这是回报：

我在网上进行了大量研究，大多数都是在stackoverflow上进行的。我找到了一些信息，但不是我想要做的解决方案。感谢有人可以帮助我。
