假设这是一张防盗链的图片,直接打开时无法显示真实图片(除chrome浏览器外),而下面是两种破解的方法:
1. 使用iframe的方法
<script>window.sc="<img src='http://cdn.archdaily.net/wp-content/uploads/2011/06/1309476244-elicium-rai-01-528x351.jpg?"+Math.random()+"'>";</script>
<iframe id="imiframe" src="javascript:parent.sc" style="border:none; overflow: hidden;" scrolling="no" frameborder="0" οnlοad="javascript:var x=document.getElementById('imiframe').contentWindow.document.images[0];this.width=x.width+10;this.height=x.height+10;"></iframe>
2. curl的方法
PHP header发送各种类型文件下载
showpic.php
<?php
$url = $_GET["url"];
//$url = str_replace("http:/","http://",$url);
$dir = pathinfo($url);
$host = $dir['dirname'];
$refer = $host.'/';
$ch = curl_init($url);
curl_setopt ($ch, CURLOPT_REFERER, $refer);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);//激活可修改页面,Activation can modify the page
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
$ext = strtolower(substr(strrchr($img,'.'),1,10));
$types = array(
'gif'=>'image/gif',
'jpeg'=>'image/jpeg',
'jpg'=>'image/jpeg',
'jpe'=>'image/jpeg',
'png'=>'image/png',
);
$type = $types[$ext] ? $types[$ext] : 'image/jpeg';
header("Content-type: ".$type);
echo $data;
遇到PHP 提示错误Cannot modify header information headers already sent ,拜托,这些代码之前不要有任何的 内容输出,包括空白!
OK 你可以这样显示图片了:
<img src="http://your-domain-name/showpic.php?url=http://cdn.archdaily.net/wp-content/uploads/2011/06/1309476244-elicium-rai-01-528x351.jpg" />
