<?php
$ADMIN[defaulturl] = "http://www.phprm.com/404.htm"; //盗链返回的地址
$okaysites = array(
    "http://www.phprm.com/",
    "http://163.com"
); //白名单
$ADMIN[url_1] = "http://www.phprm.com/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]");
}
?>
Copy after login

使用方法:将上述代码保存为dao4.php,比如测试用的validatecode.rar在站点http://phprm.com/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://www.phprm.com/dao4.php?site=1&file=validatecode.rar,以上代码测试可用
