Question

我正在尝试使用PHP访问和更新Google云端硬盘中的文件。一切顺利，直到我尝试调用$ file_to_update-＆gt; setTitle（“NEW TITLE”）。

我可以下载文件的元数据，但我无法更新任何内容。

require_once 'google-api-php-client/Google_Client.php';
require_once 'google-api-php-client/contrib/Google_DriveService.php';



$client = new Google_Client();
// Get your credentials from the console
$client->setClientId('');
$client->setClientSecret('');
$client->setRedirectUri('');
$client->setScopes(array(''));

$service = new Google_DriveService($client);

$authUrl = $client->createAuthUrl();

//Request authorization
print "Please visit:\n$authUrl\n\n";
print "Please enter the auth code:\n";
$authCode = trim(fgets(STDIN));

// Exchange authorization code for access token
$accessToken = $client->authenticate($authCode);
$client->setAccessToken($accessToken);


retrieveAllFiles($service);

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

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


  $fileIDs = array();

  $file = ($files[items]);
  foreach($file as $f){
    array_push($fileIDs, $f["id"]);
    print $f["id"]."\n";
  }

  $str = $fileIDs[1];

  $file_to_update = $service->files->get($str);

  $file_to_update->setTitle("NEW TITLE");

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

您对$ service-＆gt; files-＆gt; get（$ str）的调用不会返回对象。

如果你检查功能：

public function get($fileId, $optParams = array()) {
  $params = array('fileId' => $fileId);
  $params = array_merge($params, $optParams);
  $data = $this->__call('get', array($params));
  if ($this->useObjects()) {
    return new Google_DriveFile($data);
  } else {
    return $data;
  }
}

它会检查您是否要使用对象：

$这 - ＆GT; useObjects（）

您需要配置＆＃39; use_objects＆＃39;真的＆＃39;在你的api config.php文件中，它被设置为＆＃39; false＆＃39;默认情况下。

＆＃39; use_objects＆＃39; =＆GT;假，

Google Drive API - 尝试更新文件时，调用非对象上的成员函数
