snappy bundle中的Swiftmailer pdf附件

Question

我具有功能downloadPdf($id, \Knp\Snappy\Pdf $snappy, Request $request)。

此功能从对象下载的pdf信息一切正常。

这是功能：

public function downloadPdf($id, \Knp\Snappy\Pdf $snappy, Request $request): Response
{
    //search id
    $workOrder = $this->getDoctrine()->getRepository(WorkOrders::class)->find($id);

    //data to pdf template
    $html = $this->renderView('pdf/pdf.html.twig', array(
        'workOrder' => $workOrder,
    ));


    //name file
    $filename = $workOrder->getId();

    //download pdf
    return new PdfResponse(
        $snappy->getOutputFromHtml($html),
        $filename.'.pdf'
    );
}

然后我有了一个快速的邮件发送功能：

//check if signed and if check is true
        if ($data_uri) {
            //send workOrder to company
            if ($check == true) {
                $transport = (new \Swift_SmtpTransport('smtp.sendgrid.net', 587))
                    ->setUsername('sendgridUSERNAME')
                    ->setPassword('sendgridPASSWORD')
                    ;

                $mailer = new \Swift_Mailer($transport);

                $message = (new \Swift_Message('Werkbon '.$workOrder->getTitel()))
                    ->setFrom(['xxx' => 'xxx'])
                    ->setTo('xxx')
                    ->setBody('xxx')
                    ->attach(\Swift_Attachment::fromPath($this->downloadPdf()))
                    ;

                $result = $mailer->send($message);
            }

电子邮件工作正常，但我想在上面的代码中将其他功能的pdf附加到此电子邮件中，您可以看到我尝试过的内容，但我认为我完全错了。我不知道从哪里开始。

有人可以给我一点正确的方向吗？谢谢！

这是我的工作方式，

$invoicepdf = $this->get('knp_snappy.pdf')->getOutputFromHtml($html);



/* And instead of returning pdf, send it with mailer: */

$message = \Swift_Message::newInstance()
    ->setSubject('YOUR_TITLE')
    ->setFrom('[email protected]')
    ->setTo('[email protected]')
    ->attach(\Swift_Attachment::newInstance($invoicepdf, 'your_file_name','application/pdf'))
    ->setBody("yyy");
$mailer->send($message);
