防盗链

$ADMIN[defaulturl] = "http://siyizhu.com/404.htm";//盗链返回的地址
$okaysites = array("http://siyizhu.com/","http://www.siyizhu.com"); //白名单
$ADMIN[url_1] = "http://siyizhu.com/temp/download/";//下载地点1
$ADMIN[url_2] = "";//下载地点2,以此类推

$reffer = $HTTP_REFERER;
if($reffer) {
$yes = 0;
while(list($domain, $subarray) = each($okaysites)) {
if (ereg($subarray,"$reffer")) {
$yes = 1;
}
}
$theu = "url"."_"."$site";
if ($ADMIN[$theu] AND $yes == 1) {
header("Location: $ADMIN[$theu]/$file");
} else {
header("Location: $ADMIN[defaulturl]");
}
} else {
header("Location: $ADMIN[defaulturl]");
}

?>  
 


使用方法:将上述代码保存为dao4.php,
比如我测试用的validatecode.rar在我的站点http://siyizhu.com/temp/download里面,
则用以下代码表示下载连接.

  
文件名?site=1&file=文件 
 


例如以下URL.复制到你的站点下试试

  
http://722.512j.com/dao4.php?site=1&file=validatecode.rar
 


以上代码测试可用
