有几种方法可以做到这一点,但我更喜欢使用 .htaccess
所以我的链接看起来像http://example.com/files/filename.zip
url 中的额外参数可以使用用户名或密码,例如:
http://example.com/files/bob/filename.zip
http://example.com/files/18d52c/filename.zip
然后可以根据数据库检查是否允许用户下载该特定文件,就像您在付款后用于即时下载一样。但基本方法如下:
.htaccess
RewriteRule ^files/(.*)$ serve.php?file=$1
serve.php
<?php
if(isset($_GET['file'])){
$file=basename($_GET['file']);
//Protect the index.php && serve.php
if(basename($_GET['file'])=='index.php' || basename($_GET['file'])=='serve.php'){
header("HTTP/1.1 403 Forbidden");die();
}
$downloadFolder="original_location/";
if(file_exists($downloadFolder.$file)){
$fsize = filesize($downloadFolder.$file);
$ctype=finfo_file(finfo_open(FILEINFO_MIME_TYPE), $downloadFolder.$file);
if(ini_get('zlib.output_compression'))
ini_set('zlib.output_compression', 'Off');
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
if(strstr($_SERVER["HTTP_USER_AGENT"],"MSIE")==false) {
header("Content-Type: application/force-download");
header('Content-Description: File Transfer');
}else{
header("Content-Type: $ctype");
}
header("Content-Disposition: attachment; filename=\"".basename($file)."\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".$fsize);
ob_clean();
flush();
readfile('original_location/'.$file);
}else{
header("HTTP/1.0 404 Not Found");
}
die();
}
header("HTTP/1.0 404 Not Found");
?>
original_location/index.php
header("HTTP/1.1 403 Forbidden");
