使用第三方数据库假脱机时绕过假脱机

Question

我正在使用第三方软件包（Dextervip Citrax\DatabaseSwiftmailerBundle）将我的电子邮件发送到数据库中。但是，我仍然希望能够绕过某些特定操作的假脱机。之前，当我没有使用捆绑并仅使用常规假脱机时，我通过以下方式执行此操作：

public function sendSeparateMessage($subject, $fromEmail, $toEmail, $toCc, $body, $bypassSpool = false){

  $message = \Swift_Message::newInstance()
  ->setSubject($subject)
  ->setFrom($fromEmail)
  ->setTo($toEmail)
  ->setCc($toCc)
  ->setBody($body)
  ->setContentType("text/html");


  // Send the message
  $failedRecipients = [];
  $numSent = 0;

  foreach ($toEmail as $address => $name)
  {
    if (is_int($address)) {
      $toEmail = $message->setTo($name);
    } else {
        $toEmail = $message->setTo([$address => $name]);
    }
    $numSent += $this->mailer->send($message, $failedRecipients);
  }

  if($bypassSpool) {
    $spool = $this->mailer->getTransport()->getSpool();
  $transport = \Swift_MailTransport::newInstance();
    $spool->flushQueue($transport);
}

}

因此，只要该函数的最后一个参数设置为 true ，电子邮件就会立即发送出去，而不会存储以进行假脱机。

对于我现在的情况，我想有同样的事情，但当然我正在调用错误的 flushQueue 函数，因为我可能没有访问正确的假脱机程序。有人知道如何从该捆绑包访问假脱机程序吗？

该捆绑包中的服务类：
