此脚本适用于我的http文件服务器。我有我的文件脱离web根目录,所以我使用php脚本来抓取文件并将其发送到客户端。问题是,当我点击文件下载浏览器时(ff和chrome)不问我是否要保存文件。在chrome的网络工具中,在网络下,我看到download.php确实成功执行。事实上,我甚至可以看到文件以字节传输到请求的位置。但下载的文件不在客户端计算机上。为什么浏览器客户端询问/下载文件?PHP下载脚本工程但客户端浏览器不下载
Web服务器是Nginx。
<?php
$path = "/trunk/";
$file = $_POST['filename'];
$file_ext = pathinfo($file, PATHINFO_EXTENSION);
$file_name = pathinfo($file, PATHINFO_BASENAME);
$file_full = $path . $file_name;
$finfo = new finfo(FILEINFO_MIME_TYPE);
$ctype = $finfo -> file($file_full);
header("Content-Disposition: attachment; filename=\"".$file_name."\"");
header("Content-Type: " .$ctype);
header("Content-Length: " .filesize($file_full));
error_log(filesize($file_full));
readfile($file_full);
?>
