由于使用版本0.6从Google云端硬盘下载文件不成功，我尝试将以下功能转换为适用于PHP API客户端库的1.0.0 alpha版本。特别是我不确定的一行是调用getAuth（）的那一行。它返回一个具有空http代码响应的对象。我在下面列出了回复。任何人都可以给我一个关于我做错的指针吗？
顺便说一下，$ service对象（由授权产生）很好，因为我用它来获取文件列表没有问题。function GetFile($service, $fileId) {
$fileVars = null;
try {
$file = $service->files->get($fileId);
$fileVars = get_object_vars($file);
$downloadUrl = $file->getDownloadUrl();
if ($downloadUrl) {
$client = $service->getClient();
$request = new Google_Http_Request($client, $downloadUrl, 'GET', null, null);
$httpRequest = $client->getAuth()->sign($request);
drupal_set_message(t("Google_Http_Request: <pre>@status</pre>", array('@status' => print_r($httpRequest, TRUE))));
error_log(print_r($httpRequest, 1));
if ($httpRequest->getResponseHttpCode() == 200) {
$content = $httpRequest->getResponseBody();
$fileVars['content'] = $content?($content):'';
} else {
// An error occurred.
return null;
}
} else {
// The file doesn't have any content stored on Drive.
return null;
}
} catch (apiServiceException $e) {
error_log('Error retrieving file from Drive: ' . $e->getMessage());
throw $e;
}
return json_encode($fileVars);
}

我使用以下代码下载Google驱动器文件：
function downloadFiles($downloadUrl) {
// $default_opts = array(
// 'http' => array(
// 'follow_location' => 1
// )
// );
//
// stream_context_set_default($default_opts);
$request = new Google_Http_Request($this->getGoogleClient(), $downloadUrl, 'GET', null, null);
$SignhttpRequest = $this->getGoogleClient()->getAuth()->sign($request);
$httpRequest = $this->getGoogleClient()->getIo()->makeRequest($SignhttpRequest);
if ($httpRequest->getResponseHttpCode() == 200) {
return array($httpRequest->getResponseHeaders(), $httpRequest->getResponseBody());
} else {
return null;
}
}
