破解图片防盗链的代码(asp/php)测试通过

<?php 
$p=$_GET['p']; 
$pics=file($p); 
for($i=0;$i< count($pics);$i++) 
{ 
echo $pics[$i]; 
} 
?> 
 

使用方法：将文件保存成i.php上传到根目录 
将不能外链的图片地址改成http://你的域名p.php?p=图片地址 

asp版，网上用的比较多的
 代码如下:
<% 
Dim url, body, myCache 
url = Request.QueryString("url") 
Set myCache = new cache 
myCache.name = "picindex"&url 
If myCache.valid Then 
body = myCache.value 
Else 
body = GetWebData(url) 
myCache.add body,dateadd("d",1,now) 
End If 
If Err.Number = 0 Then 
Response.CharSet = "UTF-8" 
Response.ContentType = "application/octet-stream" 
Response.BinaryWrite body 
Response.Flush 
Else 
Wscript.Echo Err.Description 
End if 
'取得数据
