使用方法
http://yourweb/文件名.php?url=http://图片地址 或者 http://yourweb/文件名.asp?url=http://图片地址
感谢wykslina提供的引用地址,服务器不限制iis,大家可以放心用.http://wyk.org.ru/163.asp?url=http://
另外提供一个php的
http://www.8341.cn/2/krdo.php?url=
php的
<?php
if(substr($_GET[‘url’], 0, 7)!=”http://”){
exit;
}
readfile($_GET[‘url’]);
?>
还是php的
