客户端缺少内容处置标头

wireshark http php

exec("cd tex && latex {$_SESSION['sen_id']}.tex && pdflatex {$_SESSION['sen_id']}.tex", $output);
$pdf = substr($file,0,-3).'pdf';
if (file_exists($pdf)) {
  //header('Content-Description: File Transfer');
  header('Content-Type: application/pdf');
  //header('Content-Length: ' . filesize($pdf));
  header('Content-Disposition: attachment;filename='.date('Ymd-His').'-'.basename($pdf));
  header('Content-Transfer-Encoding: binary');
  header('Expires: 0');
  header('Cache-Control: no-cache');
  header('Pragma: no-cache');
  ob_clean();
  flush();
  readfile($pdf);
  exit;
} else {
  echo '<h1>No PDF Produced</h1>';
  echo nl2br(print_r($output,true));
}

使用Wireshark,我注意到contentdispositionheader要么没有设置,要么没有到达客户端。
