我想通过PHP从我的服务器下载PDF,也可以通过PDF上传。虽然它适用于某些文件,但我收到以下错误消息:单个文件:
ERR_CONTENT_LENGTH_MISMATCH
这是我的下载功能:
if($_GET['funktion'] == 'downloadallgemein')
{
$filename = basename($dateiname);
$path = '/kunden/261105_71522/webseiten/dev.delst/uploads/'.$filename.''; // the file made available for download via this PHP file
if (file_exists($path)) {
$mm_type="application/octet-stream"; // modify accordingly to the file type of $path, but in most cases no need to do so
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Type: " . $mm_type);
header("Content-Length: " .(string)(filesize($path)) );
header('Content-Disposition: attachment; filename="'.basename($path).'"');
header("Content-Transfer-Encoding: binary\n");
readfile($path); // outputs the content of the file
exit();
}
else
echo'Datei wurde nicht auf dem Server gefunden';
}
如果我删除标题(“Content-Length:”。(字符串)(filesize($ path))); 下载有效,但PDF文件会被破坏且无法打开
路径正确,文件位于服务器上。所以上传工作..
我做错了什么?
答案 0 :(得分:0)
标题('Content-Type:application / pdf');
header('Content-Disposition:attachment; filename =“'。basename($ filename)。'”');
header('Content-Length:'。filesize($ filename));
的ReadFile($文件名);
我使用此标题在我的php文件中下载pdf
