如何使用它下载文件？

谢谢。

最佳答案

您可以通过以下方式下载文件(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对象的标头返回。

谢谢。
