我如何使用它来下载文件？

谢谢。

Answer 1

您可以通过以下操作下载文件（pdf、txt、doc）：

$content = $service->files->get($file->id, array( 'alt' => 'media' ));
foreach ($content->getHeaders() as $name => $values) {
    header($name . ': ' . implode(', ', $values));
}
header('Content-Disposition: inline; filename="' . $yourfilename . '"');
echo $content->getBody();

使用GuzzleHttp对象返回的头。

谢谢。
