上传到谷歌云存储桶不起作用

Question

我正在使用最新的库google php-api-client

当我尝试上传时，我收到以下错误

PHP Warning:  file_get_contents(/upload/storage/v1beta2/b/filetransfer/o?uploadType=multipart): failed to open stream: No such file or directory in /src/Google/IO/Stream.php on line 109

用户将图像上传到我的服务器，我在服务器端进行处理，然后将图像发布到我的云存储桶......这是我的代码人员

一旦用户上传了图像，它就会被处理并驻留在我服务器上的/temp/目录中，然后我会执行以下操作

// Instantiate the Google Cloud Storage Client
$client = new Google_Client();
$client->setApplicationName("MY_CLOUD_STORAGE");
$service = new Google_Service_Storage($client);
if (isset($_SESSION['service_token'])) {
        $client->setAccessToken($_SESSION['service_token']);
 }
$key = file_get_contents($key_file_location);
$cred = new Google_Auth_AssertionCredentials(
           $service_account_name,
           array($gcs_url),
             $key
  );
$client->setAssertionCredentials($cred);
if($client->getAuth()->isAccessTokenExpired()) {
           $client->getAuth()->refreshTokenWithAssertion($cred);
 }
 $_SESSION['service_token'] = $client->getAccessToken();
 $objects = $service->objects;
 $gso = new Google_Service_Storage_StorageObject();
  $gso->setName("image.gif");
 $imgdata = file_get_contents($server_image_path);
 $postbody = array('uploadType' => 'multipart', 'data' => $imgdata);
 try {
 $result = $objects->insert('filetransfer', $gso, $postbody);
 } catch(Exception $e) {
  }
