我想将我的Google驱动器中的所有文件列出到我的“DriveFiles.php”文件中,我可以在其中显示文件及其详细信息。我是一个初学者,所以完整的代码将会有所帮助。谢谢。列出Google Drive中的所有文件

我的代码:

<?php 


require_once 'google-api-php-client/src/Google_Client.php'; 
require_once 'google-api-php-client/src/contrib/Google_DriveService.php'; 
require_once 'google-api-php-client/src/io/Google_HttpRequest.php'; 
require_once 'google-api-php-client/src/contrib/Google_Oauth2Service.php'; 

// initialize a client with application credentials and required scopes. 
$client = new Google_Client(); 
$client->setClientId('CLIENT_ID'); 
$client->setClientSecret('CLIENT_SECRET'); 
$client->setRedirectUri('REDIRECT_URI'); 
$client->setScopes(array(
      'https://www.googleapis.com/auth/drive', 
      'https://www.googleapis.com/auth/userinfo.email', 
      'https://www.googleapis.com/auth/userinfo.profile')); 
$client->setUseObjects(true); 


if (isset($_GET['code'])) 
    { 
    session_start(); 
    print_r($_SESSION); 
    $client->authenticate($_GET['code']); 
    $_SESSION['token'] = $client->getAccessToken(); 
    $client->setAccessToken($_SESSION['token']); 
    // initialize the drive service with the client. 
    $services = new Google_DriveService($client); 
    retrieveAllFiles($services);  

    } 



if(!$client->getAccessToken()){ 
    $authUrl = $client->createAuthUrl(); 
    echo '<a class="login" href="'.$authUrl.'">Login</a>'; 
    } 


function retrieveAllFiles($service) { 
    $result = array(); 
    $pageToken = NULL; 

      do { 
      try { 
       $parameters = array(); 
       if ($pageToken) { 
       $parameters['pageToken'] = $pageToken; 
       } 
       $files = $service->files->listFiles($parameters); 

       $result = array_merge($result, $files->getItems()); 
       $pageToken = $files->getNextPageToken(); 
      } catch (Exception $e) { 
       print "An error occurred: " . $e->getMessage(); 
       $pageToken = NULL; 
      } 
      } while ($pageToken); 
      return $result; 
     } 
     ?> 

当我执行的代码,我得到了以下错误:

Fatal error: Uncaught exception 'Google_Exception' with message 'Cant add services after having authenticated' in D:\GT_local\Public\google-api-php-client\src\Google_Client.php:115 Stack trace: #0 D:\GT_local\Public\google-api-php-client\src\contrib\Google_DriveService.php(1258): Google_Client->addService('drive', 'v2') #1 D:\GT_local\Public\quickstart.php(55): Google_DriveService->__construct(Object(Google_Client)) #2 {main} thrown in "FILE_LOCATION(C://google-api-php-client\src\Google_Client.php on line 115)"

我怎样才能解决这个问题。

我会从最新的客户端库开始。你正在使用的那个不再被开发。 https://github.com/google/google-api-php-client – DaImTo 2014-11-04 09:47:51

尝试在脚本顶部开始会话,并在您必须执行任何操作之前尝试执行所有身份验证。同样使用最新的API,因此您可以使用这些库:

require_once '/src/Google/autoload.php'; 
require_once '/src/Google/Client.php'; 
require_once '/src/Google/Service/Oauth2.php'; 
require_once '/src/Google/Service/Drive.php';
