1、假设充许连结图片的主机域名为:www.test.com

2、修改httpd.conf

 SetEnvIfNoCase Referer "^http://www.test.com/" local_ref=1

Order Allow,Deny
Allow from env=local_ref
 
 


这个简单的应用不光可以解决图片盗链的问题,稍加修改还可以防止任意文件盗链下载的问题。

使用以上的方法当从非指定的主机连结图片时,图片将无法显示,如果希望显示一张“禁止盗链”的图片,我们可以用mod_rewrite 来实现。

首先在安装 apache 时要加上 --enable-rewrite 参数加载 mod_rewrite 模组。

假设“禁止盗链”的图片为abc.gif,我们在 httpd.conf 中可以这样配置:


RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?test.com /.*$ [NC]
RewriteRule \.(gif|jpg)$ http://www.test.com/abc.gif [R,L] 
 


当主机的图片被盗链时,只会看到 abc.gif 这张“禁止盗链”的图片!
