Question

我正在使用mongodb和php。我有协议下载选项，当用户点击用户获得同意下载。点击后，我已导航到脚本，其中有php中的文件下载代码代码是

$mongoDbA = $mongoDb->findOne(array("agency_id" => new MongoId($_GET['id'])));
$filename = '../../images/upload/'.$mongoDbA['file'];

if (file_exists($filename)) 
{
header('Content-Description: File Transfer');
header('Content-Type: text/pdf');
header('Content-Disposition: attachment; filename='.basename($filename));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($filename));
readfile($filename);
exit;
}

我只允许上传pdf文件，因此数据库中只有pdf文件

当我点击它然后它给了我错误＆amp;给了我没有扩展名的白色文件＆amp;大小是1 kb几乎......发生了什么???

Answer 1

$filename = './images/upload/'.$mongoDbA['file'];

    $fileinfo = pathinfo($filename);
    $sendname = $fileinfo['filename'] . '.' . $fileinfo['extension'];

    header('Content-Type: application/pdf');
    header('Content-Disposition: attachment; filename="$sendname"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($filename));
    readfile($filename);
    exit;
