我试图通过以下代码附加 dompdf 文件而不保存到服务器：
我从 PHP 响应中得到的错误是：消息无法发送。邮件错误：未知编码：pdffilename.pdf
现在，我尝试使用 $mail->addAttachment 而不是 $mail->addStringAttachment 添加 base64，但是这些都不起作用，而且我不断收到错误。
我希望将 PDF 直接附加到电子邮件中，而不保存到服务器。
想知道是否有人可以帮忙！

exit();

catch (Exception $e)

echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}

使用 Sendgrid 的 PHP 库
use SendGrid\Mail\Mail;
我已经解决了这个问题并使用以下代码成功附加了我的 DOMPDF 文件：
$output = $dompdf->output();
$mail->addAttachment($output,'application/pdf','filename.pdf', 'attachment');
我想使用 PHPMailer 库也是同样的情况，但是，Sendgrid PHP 库正是我使用 Sendgrid API 发送邮件所需要的。
希望这可以帮助其他人寻找..
