PHP将文件上传到Google云端硬盘 [英] PHP upload a file on google Drive

问题描述

我正在学习Google驱动器API并从此文档中学习( https://developers.google.com/drive/v3/web/manage-uploads )中有一个代码示例，但是在代码中的某个地方，我发现了一些错误.

I am learning google drive API and from this documentation (https://developers.google.com/drive/v3/web/manage-uploads) there is a code example but somewhere in the code, I find something wrong.

这是Google api文档中的代码:

This is the code in the google api documentaiton:

$fileMetadata = new Google_Service_Drive_DriveFile(array(
  'name' => 'photo.jpg'));
$content = file_get_contents('files/photo.jpg');
$file = $driveService->files->create($fileMetadata, array(
  'data' => $content,
  'mimeType' => 'image/jpeg',
  'uploadType' => 'multipart',
  'fields' => 'id'));
printf("File ID: %s\n", $file->id);

但是我不知道，这段代码是如何工作的，因为$ driveService之前没有初始化或为空

But I do not know, how this piece of code works since $driveService was not initialized before or it is null

$file = $driveService->files->create($fileMetadata, array(
      'data' => $content,
      'mimeType' => 'image/jpeg',
      'uploadType' => 'multipart',
      'fields' => 'id')); 

有人可以帮我吗.非常感谢你.

Can someone help me please. Thank you very much.

推荐答案

您忘记先阅读快速入门.

You forgot to read the quickstart first.

https://developers.google.com/drive/v3/web/quickstart/php

第3步是完整的PHP实施，服务为 $ service = new Google_Service_Drive($ client);

Full PHP Implement is in step 3 and the service is $service = new Google_Service_Drive($client);
