我正在使用以下代码开始下载,但下载的弹出窗口未打开。相反,它显示该 pdf 文件的二进制格式。它在本地服务器上运行良好,但在托管服务器上运行不正常。
$file = '../Notes/chapter01.pdf';
if (file_exists($file)) {
header('Content-Description: File Transfer');
// header('Content-Type: application/octet-stream');
header('Cache-Control: public'); // needed for i.e.
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
//header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_end_clean();
flush();
readfile($file);
exit;
}
else {
die('Error: File not found.');
}
