如何使用PHP使用Google Drive API正确定义Google_Service_Drive变量来创建文件夹？

Question

我是新手，因此希望您能对我有所帮助，我正在检查Google Drive API文档，因为我想使用PHP在Google Drive中创建一个文件夹，我使用的是代码示例，但我注意到我必须首先定义此“ $ driveService”变量。

我必须说我之前已经完成了前面的步骤（创建项目，通过composer安装，生成我的client_secret.json文件等）。

因此，我尝试使用编写以下代码的示例：

<?php
 require_once __DIR__.'/vendor/autoload.php';

 $client = new Google_Client();
 $client->setAuthConfigFile('64*****-client_secret.json');
 $client->setRedirectUri('https://www.mywebsite.com/drive/oauth2callback.php');
 $client->addScope(Google_Service_Drive::DRIVE);

 $driveService = new Google_Service_Drive($client);
 $fileMetadata = new Google_Service_Drive_DriveFile(array(
   'name' => 'TEST',
   'mimeType' => 'application/vnd.google-apps.folder'));

 $file = $driveService->files->create($fileMetadata, array('fields' => 'id'));

 printf("Folder ID: %s\n", $file->id);

?>

但是，当我执行该页面时，它在浏览器中什么也没显示，而是在终端中显示：

PHP Fatal error:  Uncaught exception 'Google_Service_Exception' with 
 message '{
  "error": {
  "errors": [
  {
   "domain": "global",
   "reason": "required",

   "locationType": "header",
   "location": "Authorization"
  }
 ],
 "code": 401,
 "message": "Login Required"
 }
}

我还添加了以下几行：

 $client = new Google_Client();
 $client->setAuthConfigFile('64*****-client_secret.json');
 $client->setRedirectUri('https://www.mywebsite.com/drive/oauth2callback.php');
 $client->setAuthConfig('credentials.json');
 $client->setAccessType('offline');
 $client->addScope(Google_Service_Drive::DRIVE);

但是仍然一样，我无法创建文件夹并获取文件夹ID。 我该如何解决？

谢谢您的回答。

您需要先获取访问令牌； 用户需要通过用户同意屏幕授予您对其驱动器文件的访问权限。 哟可以试试看；

 $client = new Google_Client();
 $client->setAuthConfigFile('64*****-client_secret.json');
 $client->setRedirectUri('https://www.mywebsite.com/drive/oauth2callback.php');
 $client->addScope(Google_Service_Drive::DRIVE);

         /** checks if the access token has previously been obtained and sets it **/
    if (isset($_SESSION['access_token']) && $_SESSION['access_token']){
    $client->setAccessToken($_SESSION['access_token']);
     //what ever code you want to run
      else{
     //redirects the user to authenticate
  $redirect_uri = 'https://www.mywebsite.com/drive/oauth2callback.php';
    header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
    }

    }

$ client-> setAuthConfig（'credentials.json'）; 您添加的是重复项，没有必要。 同样要记住在这样的代码开头调用会话开始：session_start（）;
