使用PHP使用Google Drive API上传文件

Question

我正在尝试使用PHP将文件上传到Google云端硬盘，我已经复制了官方Google代码（https://developers.google.com/drive/api/v3/manage-uploads） 当我从CLI运行文件时，出现此错误：

PHP Fatal error:  Uncaught Google_Service_Exception: {
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "insufficientPermissions",
    "message": "Insufficient Permission: Request had insufficient authentication scopes."
   }
  ],
  "code": 403,
  "message": "Insufficient Permission: Request had insufficient authentication scopes."
 }
}

代码：

//Omitted code can be found here -> https://developers.google.com/drive/api/v3/quickstart/php
// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Drive($client);


$fileMetadata = new Google_Service_Drive_DriveFile(array('name' => 'backup.sql'));
$content = file_get_contents('/var/www/html/backup-db/backup.sql');
$file = $service->files->create($fileMetadata, array(
    'data' => $content,
    'mimeType' => 'application/sql',
    'uploadType' => 'multipart',
    'fields' => 'id'));
printf("File ID: %s\n", $file->id);
