dedecms How to prevent hotlinking in software download channels?
Due to website revision, many previous websites were linked to our internal pages. This results in a poor user experience and prevents some websites from stealing our resources.

dedeThe shortcomings of making a software site
is that others repost your downloads When reposting http://www.xxx.com/plus/download.php...
, you can download it by directly opening the download address list page, which costs a lot of money Resources but cannot bring users.
After research, I finally solved the problem of anti-leeching for software channel downloads. The code is distributed and shared with everyone. I hope it can be used.
The modified function is
If the software information The page address is: https://www.xxx.net/soft/1.htm
The download address link is: https://www.xxx.net/plus/download.php?.... .....
Determine the origin,
If it is not https://www.xxx.net/soft/1.htm,
Jump directly to https ://www.xxx.net/soft/1.htm
If the source is https://www.xxx.net/soft/1.htm, the download address will be displayed
Description Next: The code below is directly copied from my own site. I have enabled Thunder download for the whole site. When I open it, Thunder download will be automatically used. You can also make small modifications to prevent the use of Thunder download
No It is easy to modify using Xunlei: delete the Xunlei related code and just quote $link
The file that needs to be modified is /plus/download.php
Demo:
https://www.xxx.net/do/plus/download.php?open=0&aid=20975&cid=3
Must start from https://www.xxx.net/codes/20975.html It is normal to enter the page.
The code is as follows:
<script src="http://pstatic.xunlei.com/js/webThunderDetect.js"></script>
<?php require("encode.inc"); ?>
<?php
require_once(dirname(__FILE__)."/../include/config_base.php");
require_once(dirname(__FILE__)."/../include/inc_channel_unit.php");
if(!isset($open)) $open = 0;
if(!isset($aid)) $aid = "";
$dsql = new DedeSql(false);
//读取文档基本信息
$arctitle = "";
$arcurl = "";
$gquery = "Select
dede_archives.title,dede_archives.senddate,dede_archives.arcrank,
dede_archives.ismake,dede_archives.typeid,dede_archives.channel,dede_archives.money,
dede_arctype.typedir,dede_arctype.namerule
From dede_archives
left join dede_arctype on dede_arctype.ID=dede_archives.typeid
where dede_archives.ID='$aid'
";
$arcRow = $dsql->GetOne($gquery);
if(is_array($arcRow)){
$arctitle = $arcRow['title'];
$arcurl = GetFileUrl($aid,$arcRow['typeid'],$arcRow['senddate'],$arctitle,$arcRow['ismake'],$arcRow['arcrank'],$arcRow['namerule'],$arcRow['typedir'],$arcRow['money']);
}else{
$dsql->Close();
ShowMsg("无法获取未知文档的信息!","-1");
exit();
}
$cu = new ChannelUnit($arcRow['channel'],$aid);
if(!is_array($cu->ChannelFields)) {
$cu->Close();
$dsql->Close();
ShowMsg("获取文档链接信息失败！","-1");
exit();
}
$vname = "";
foreach($cu->ChannelFields as $k=>$v){
if($v['type']=="softlinks"){ $vname=$k; break; }
}
if(!is_array($cu->ChannelFields)) {
$cu->Close();
$dsql->Close();
ShowMsg("获取文档链接信息失败！","-1");
exit();
}
if(!strstr($_SERVER['HTTP_REFERER'],$arcurl))
{
echo "<script language='javascript'>location=\"$arcurl\";</script>";
}
$row = $dsql->GetOne("Select $vname From ".$cu->ChannelInfos['addtable']." where aid='$aid'");
$downlinks = $cu->GetAddLinks($row[$vname]);
$dsql->Close();
$cu->Close();
$link = base64_decode($link);
$thunderUrl = ThunderEncode($link);
echo "<script>OnDownloadClick('".$thunderUrl."','',location.href,'07231',2,'')</script>";

link display method in the channel settings: Request to enter the download address list page
2. If the example situation is different from your website, you can also manually modify your /plus/download .php
The modification method is as follows:
Find:
$row = $dsql->GetOne("Select $vname From ".$cu->ChannelInfos['addtable']." where aid='$aid'");Add
if(!strstr($_SERVER['HTTP_REFERER'],$arcurl))
{
echo "<script language='javascript'>location=\"$arcurl\";</script>";
