在 php 中使用 google 驱动器 api 列出所有文件时出错

Question

我正在使用 PHP 开发 google 驱动器 api。我在使用此驱动器 api 时遇到错误。我正在使用 google api 客户端库 "google/apiclient ^2.0"。我正在尝试使用 google 身份验证进行用户登录，并为此目的查看驱动器中可用的所有文件，我正在使用此库，但它显示错误：

Notice: Undefined property: Google_Client::$files in /Applications/XAMPP/xamppfiles/htdocs/google_app/index.php on line 31

Fatal error: Uncaught Error: Call to a member function listFiles() on null in /Applications/XAMPP/xamppfiles/htdocs/google_app/index.php:31 Stack trace: #0 /Applications/XAMPP/xamppfiles/htdocs/google_app/index.php(55): retrieveAllFiles(Object(Google_Client)) #1 {main} thrown in /Applications/XAMPP/xamppfiles/htdocs/google_app/index.php on line 31

include_once   'vendor/autoload.php';


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;
}


$client = new Google_Client();
$client->setAuthConfig('client_secrets.json');
$client->setAccessType("offline");        // offline access
//$client->setIncludeGrantedScopes(true);   // incremental auth
$client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
$redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
$client->setRedirectUri($redirect_uri);
if (isset($_GET['code'])) {
    $token = $client->fetchAccessTokenWithAuthCode($_GET['code']);
}
$service = new Google_service_Device();
echo retrieveAllFiles($service );

实际上我正在尝试使用我的文件 ID 检索我的 google 驱动器中的所有文件，然后设置状态自动发布特定文件。请帮助我摆脱这个错误。

提前致谢。

"Daily limit for unauthenticated Use Exceeded"

表示您在未正确验证脚本的情况下发出请求。您的 fetchAccessTokenWithAuthCode 可能有问题。

您可能会考虑使用较长的这些行

function getOauth2Client() {
    try {

        $client = buildClient();

        // Set the refresh token on the client. 
        if (isset($_SESSION['refresh_token']) && $_SESSION['refresh_token']) {
            $client->refreshToken($_SESSION['refresh_token']);
        }

        // If the user has already authorized this app then get an access token
        // else redirect to ask the user to authorize access to Google Analytics.
        if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {

            // Set the access token on the client.
            $client->setAccessToken($_SESSION['access_token']);                 

            // Refresh the access token if it's expired.
            if ($client->isAccessTokenExpired()) {              
                $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
                $client->setAccessToken($client->getAccessToken()); 
                $_SESSION['access_token'] = $client->getAccessToken();              
            }           
            return $client; 
        } else {
            // We do not have access request access.
            header('Location: ' . filter_var( $client->getRedirectUri(), FILTER_SANITIZE_URL));
        }
    } catch (Exception $e) {
        print "An error occurred: " . $e->getMessage();
    }
}

从我的示例项目中提取的代码 oauth2php

Undefined property Google_Client

表示您没有正确声明 google 客户端

Uncaught Error: Call to a member function listFiles() on null in

如果删除 $parameters 并只调用 $service->files->listFiles();

会发生什么
