php - 在 Laravel 中使用 Google Drive API

Question

我想在我的 Laravel 项目中使用 Google Drive API 来存储 PDF。不幸的是，示例代码是针对普通 PHP 的，我不知道如何在 Laravel 中实现它。

<?php
  require_once 'Google/Client.php';
  require_once 'Google/Service/Books.php';
  $client = new Google_Client();
  $client->setApplicationName("Client_Library_Examples");
  $client->setDeveloperKey("YOUR_APP_KEY");
  $service = new Google_Service_Books($client);
  $optParams = array('filter' => 'free-ebooks');
  $results = $service->volumes->listVolumes('Henry David Thoreau', $optParams);

  foreach ($results as $item) {
    echo $item['volumeInfo']['title'], "<br /> \n";
  }

我想我必须包括 https://github.com/google/google-api-php-client在我的依赖项中，但我不知道如何访问 API 的功能。

谁能帮帮我？

问候和感谢。
