使用PHPMailer发送电子邮件后无法打开FPDF PDF文件

Question

我正在尝试使用FPDF创建一个PDF文件，并使用PHPMailer通过电子邮件发送。它确实发送了文件，但由于某些原因，我无法打开文件，无论是从我的电子邮件还是使用 Adobe Reader（这给了我一些文件损坏的东西）。

这是我的代码

require('fpdf.php');
require 'PHPMailerAutoload.php';
header("Access-Control-Allow-Origin: *");
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','UB',28);
$pdf->Cell(0,10,"My Profile",0,1,'C');
$pdf->Ln();
$mail = new PHPMailer();
$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = '[e-mail]';                 // SMTP username
$mail->Password = 'password';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;
// a random hash will be necessary to send mixed content
$separator = md5(time());
// carriage return type (we use a PHP end of line constant)
$eol = PHP_EOL;
// main header
$headers  = "From: ".$from.$eol;
$headers .= "MIME-Version: 1.0".$eol; 
$headers .= "Content-Type: multipart/mixed; boundary="".$separator.""";
// no more headers after this, we start the body! //
$body = "--".$separator.$eol;
$body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;
$body .= "This is a MIME encoded message.".$eol;
// message
$body .= "--".$separator.$eol;
$body .= "Content-Type: text/html; charset="iso-8859-1"".$eol;
$body .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$body .= $message.$eol;
// attachment
$body .= "--".$separator.$eol;
$body .= "Content-Type: application/octet-stream; name="".$filename.""".$eol; 
$body .= "Content-Transfer-Encoding: base64".$eol;
$body .= "Content-Disposition: attachment".$eol.$eol;
$body .= $attachment.$eol;
$body .= "--".$separator."--";
$pdfdoc = $pdf->Output('','S');
$attachment = chunk_split(base64_encode($pdfdoc));
//Set who the message is to be sent from
$mail->setFrom('[e-mail]', 'Baby Diary');
//Set who the message is to be sent to
$mail->addAddress('[e-mail]', 'haha');
//Set the subject line
$mail->Subject = 'PHPMailer mail() test';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AddStringAttachment($attachment, 'doc.pdf', 'base64', 'application/pdf');
if (!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message sent!";
}

当我使用 $pdf->Output（） 时，它确实给了我输出，这暗示我问题不应该出在 FPDF 端。任何建议将不胜感激。

你的问题出在phpmailer上，而不是fpdf上。尝试使用标准的 PHPMailer 类方法。

如果我是你，我会尝试从 PHPMailer 文档示例中包含的附加示例重写您的代码。特别是我会坚持使用PHPMailer方法，而不是做我自己的smtp格式化。

因此，首先将pdf保存到文件，然后尝试使用$mail->addAttachment()附加文件。并让PHPMailer处理邮件的格式。

所以你最终可能会得到下面这样的代码（我没有运行它，你可能需要微调它）：

require('fpdf.php');
require 'PHPMailerAutoload.php';
header("Access-Control-Allow-Origin: *");
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','UB',28);
$pdf->Cell(0,10,"My Profile",0,1,'C');
$pdf->Ln();
$pdfoutputfile = '/some-tmp-dir/temp-file.pdf';
$pdfdoc = $pdf->Output($pdfoutputfile, 'F');
// We're done with the pdf generation
// now onto the email generation
$mail = new PHPMailer();
$mail->isSMTP();                 // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;          // Enable SMTP authentication
$mail->Username = '[e-mail]';   // SMTP username
$mail->Password = 'password';            // SMTP password
$mail->SMTPSecure = 'tls';       // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;
$separator = md5(time());        // a random hash will be necessary to send mixed content
//Set who the message is to be sent from
$mail->setFrom('[e-mail]', 'From Test address');
//Set who the message is to be sent to
$mail->addAddress('[e-mail]', 'to test address');
//Set the subject line
$mail->Subject = 'Test message with attachement';
$mail->Body    = 'Test message with attached files.';
$mail->AddAttachment($pdfoutputfile, 'my-doc.pdf');
if (!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message sent!";
}
