我正在尝试使用dompdf创建文件并将其附加到mime,而不进行保存。我从https://stackoverflow.com/a/12008553/9727103得到了答案,所以我使用了它,但是电子邮件中包含了某些意外内容。

这是我的部分代码。

$pdf = $dompdf->output();

$mm = new Mail_mime();

$msg = 'Hello world to all.';

$mm->setTxtBody($msg);
$mm->addAttachment($pdf,'application/pdf','output.pdf', false);

$body = $mm->get();
$subject = 'Hello World - ['.$customer.']';

$recipients = 'a@b.com';
$headers['From']= 'ab@bc.com'; 
$headers['To']= 'a@b.com';
$headers['Subject'] = $subject;
$params['host'] = 'smtp.sendgrid.net';
$params['port'] = '587';
$params['auth'] = true;
$params['username'] = 'my@user.name';
$params['password'] = 'my@user.pass';


$mail_object = Mail::factory('smtp', $params); // Print the parameters you are using to the page

// Send the message
$mail_object->send($recipients, $headers, $body);
if (PEAR::isError($mail_object)) {
    echo("<p>" . $mail_object->getMessage() . "</p>");
} else {
    echo("Message sent!");
}

它发送成功,但是我收到的电子邮件是这个。

附加的文件转换为字符串,并且有

Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset=ISO-8859-1

我没打算。当我使用https://www.freeformatter.com/base64-encoder.html#ad-output复制pdf字符串并单击“解码并下载”时,它会下载我附加的pdf文件,但我希望它只是附带附件的普通电子邮件。

有什么办法可以解决这个问题?任何帮助将不胜感激。谢谢!

我认为您错过了重点。 PDF已正确附加到您的电子邮件中。您的电子邮件(根据您的帖子)包含:

Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset=ISO-8859-1

并且:

Content-Transfer-Encoding: base64
Content-Type: application/pdf;
 name=output.pdf
Content-Disposition: attachment;
 filename=output.pdf;
 size=5444

如果您在电子邮件客户端中查看此电子邮件,您将看到PDF作为附件出现,并且电子邮件中的消息将是“所有人的世界您好”。纯文本格式(即无格式)。
