复制代码 代码如下:
<?php
/**

$ADMIN = array(
"defaulturl"=> "http://www.xx.com/images/banner-header.gif", //盗链返回的地址
"url_1" => "http://www.xx.net/file",
"url_2" => "http://www.xx.net/file1",
);
$okaysites = array(
"http://box.baidu.com",
"http://tieba.baidu.com/p/1493336008", //白名单
"http://www.xx.com/1.html",
);
$reffer = $_SERVER["HTTP_REFERER"];
if ($reffer) {
$yes = 0;
while (list($domain, $subarray) = each($okaysites)) {
if (ereg($subarray, "$reffer")) {
$yes = 1;
}
}
$theu = "url_" . $_GET["site"];
$file = $_GET["file"];
if ($ADMIN[$theu] and $yes == 1) {
header("Location: $ADMIN[$theu]/$file");
} else {
header("Location: $ADMIN[defaulturl]");
}
} else {
header("Location: $ADMIN[defaulturl]");
}
print_r($_SERVER["HTTP_REFERER"]);
?>
