【问题描述】：

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";
  

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

谁能帮帮我？

问候和感谢。

【参考方案1】：

Laravel 使用 Composer 来处理依赖关系。在您的 composer.json 文件中添加 google/apiclient 作为依赖项。

【讨论】：

是的，我做到了。但我不知道如何调用控制器中的函数。

【参考方案2】：

<?php
    require_once "protected/vendor/google-api-php/Google/Client.php";
    require_once "protected/vendor/google-api-php/Google/Service/Drive.php

    $client = new Google_Client();

    $dr_service = new Google_Service_Drive($client);
    $file = new Google_Service_Drive_DriveFile();
    $file = new Google_Service_Drive_DriveFile();

    $mimetype = 'application/pdf';
    $uploadType = 'media';
    $filetitle = $file_name;
    $filedescription = 'Taskew ' . $model['discussion_title'];

    $datetime = date('d-m-y-h:s');

    $file->setTitle($datetime . $filetitle);
    $file->setDescription($filedescription);
    $file->setMimeType($mimetype);

    $data = file_get_contents($folder . $file_name);

    $createdFile = $dr_service->files->insert($file, array(
    'data' => $data,
    'mimeType' => $mimetype, //text/plain',
    'uploadType' => $uploadType
    ));

【讨论】：

Google_Service_Exception in REST.php ，需要登录，错误编号 401

【参考方案3】：

用于登录 + 驱动器上的文件上传 (https://github.com/google/google-api-php-client/blob/master/examples/large-file-upload.php)
