Google Drive Api与php的集成

Question

我想将我的谷歌驱动器显示到网站中。这意味着如果有人使用我的网站可以看到谷歌驱动器文件和文件夹没有登录。这里是我试图实现的一些代码。

include_once 'google-api-php-client/src/Google/autoload.php'; 
    $scopes = array('https://www.googleapis.com/auth/drive','https://www.googleapis.com/auth/drive.appdata', 
    'https://www.googleapis.com/auth/drive.file','https://www.googleapis.com/auth/drive.metadata','https://www.googleapis.com/auth/drive.metadata.readonly','https://www.googleapis.com/auth/drive.photos.readonly','https://www.googleapis.com/auth/drive.readonly'); 

    /** 
    * Create AssertionCredentails object for use with Google_Client 
    */ 
    $creds = new Google_Auth_AssertionCredentials(
     $serviceAccountName, 
     $scopes, 
     file_get_contents($keyFile) 
    ); 

    $creds->sub = $delegatedAdmin; 

    /** 
    * Create Google_Client for making API calls with 
    */ 
    $client = new Google_Client(); 
    $client->setApplicationName($appName); 
    $client->setClientId($clientId); 
    $client->setAssertionCredentials($creds); 

    /** 
    * Get an instance of the Directory object for making Directory API related calls 
    */ 
    $service = new Google_Service_Drive($client); 

    $optParams = array(
     'pageSize' => 10, 
     'fields' => "nextPageToken, files(id, name)" 
    ); 
    $results = $service->files->listFiles($optParams); 
    print_r($results); exit; 
    /** 

任何人都可以告诉我如何实现这一点。我收到此错误

Fatal error: Uncaught exception 'Google_Auth_Exception' with message 'Error refreshing the OAuth2 token, message: '{ "error" : "unauthorized_client", "error_description" : "Unauthorized client or scope in request." }

您需要添加

if ($client->getAuth()->isAccessTokenExpired()) { 
    $client->getAuth()->refreshTokenWithAssertion(); 
} 

后

$client->setAssertionCredentials($creds);
