无法通过Google API将文件上传到Google云端硬盘

问题描述：

当我尝试通过Google API上传文件到Google云端硬盘时（https://github.com/google/google-api-php-client），我收到错误“权限不足”（读取的文件没有任何问题）。这里是代码示例：无法通过Google API将文件上传到Google云端硬盘

require_once 'google-api-php-client/vendor/autoload.php'; 

class GoogleConnector { 
    private $client; 
    public $report; 

    function __construct($filesToSend, $backupFolder) { 
     session_start(); 
     $this->client = new Google_Client(); 
     $this->client->setAuthConfig('client_secret.json'); 
     $this->client->addScope("https://www.googleapis.com/auth/drive"); 
     //also try different variants of this: 
     //$this->client->setScopes(implode(' ', array(Google_Service_Drive::DRIVE))); 

     if (isset($_SESSION['access_token']) && $_SESSION['access_token']) { 
      $this->client->setAccessToken($_SESSION['access_token']); 
      $service = new Google_Service_Drive($this->client); 
      $folderId = "FolderIdFromGoogleDrive"; 

      $this->report = ""; 
      foreach ($filesToSend as $file) { 
       $this->report .= $this->uploadFile($file, $folderID, $service); 
      } 
     } 
     else { 
      $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/googleapi/oauth2callback.php'; 
      header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL)); 
     } 
    } 

    function uploadFile($fileName, $folderID, Google_Service_Drive $driveService) { 
     $fileMetadata = new Google_Service_Drive_DriveFile(array(
       'name' => $fileName, 
       'parents' => array($folderId) 
     )); 

     try { 
      $content = file_get_contents($fileName); 
      $file = $driveService->files->create($fileMetadata, array(
        'data' => $content, 
        'mimeType' => 'application/x-gzip', 
        'uploadType' => 'multipart', 
        'fields' => 'id')); 
      return "File '$fileName' uploaded with id '$file->id'" . PHP_EOL; 
     } 
     catch (Exception $exc) { 
      return "Error working with file '$fileName':" . $exc->getMessage(); 
     } 
    } 
}

我该如何解决它？

确保您使用验证用户可以访问“FolderIdFromGoogleDrive – DaImTo

我只使用一个用户和该用户可以创建内部文件‘通过谷歌驱动的网站FolderIdFromGoogleDrive’。 – Varro

显然，如果你得到“权限不足”，试着做一个file.list，并确保该文件夹出现给用户，如果出现然后重新认证用户，你必须使用差别范围认证一次，然后 – DaImTo

答

确保你有效的Permissions for the file。您必须将权限角色设置为“所有者”，并将角色设置为用户（因为您是上传者）。
