第8行;valid_referers none blocked *.espressos.cn *qq.com *baidu.com ;
就是白名单，允许文件链出的域名白名单，自行修改成您的域名！ *.espressos.cn这个指的是子域名，域名与域名之间使用空格隔开！baidu.com是搜索引擎，做qq.com的白名单是因为可能有用户用邮箱订阅你的站点，如果不设置为白名单，用户在邮箱就无法看见你的图了，同理，如果还有其他订阅方式、搜索引擎都最好添加一下。
验证代码：
[root@web01 www]# cat q.html <html> <body><img alt="http://192.168.1.24/cat.png" src="http://192.168.1.24/cat.png" height="auto" width="auto"></body> </html> [root@web01 www]#
另一台WEB服务器盗用WEB01的图片（配置如下）：
[root@lmr default]# cat /app/server/nginx/conf/vhosts/default.conf server { listen 80; server_name localhost; index index.html index.htm index.php; root /app/www/default; location ~ .*.(php|php5)?$ { #fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi.conf; } location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*.(js|css)?$ { expires 1h; } include /app/server/nginx/conf/rewrite/default.conf; access_log /app/log/nginx/access/default.log; }
验证：
[root@lmr default]# pwd /app/www/default [root@lmr default]# cat q.html <html> <body><img alt="http://192.168.1.24/cat.png" src="http://192.168.1.24/cat.png" height="auto" width="auto"></body> </html> [root@lmr default]#
防盗成功！！！
把web01上的防盗代码注释掉：
[root@web01 www]# cat /app/server/nginx/conf/vhosts/default.conf server { listen 80 default_server; server_name 192.168.1.24 web01.espressos.cn; root /app/www; index index.php index.html index.htm; #location ~* .(gif|jpg|png|swf|flv)$ { #valid_referers none blocked 192.168.1.24 web01.espressos.cn; #if ($invalid_referer) { # rewrite ^/ http://192.168.1.24/403.html; # return 404; # } #} location ~ .*.(php|php5)?$ { #fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi.conf; } access_log /app/log/nginx/access/default.log; } [root@web01 www]# /app/server/nginx/sbin/nginx -s reload
重新测式盗连图片的服务器，盗图是否成功：
图片盗连成功！！

注意上面的第19和20行：（图片服务器的IP：123.57.37.211）
[root@lmr default]# cat q.html <html> <body><img alt="cat.png" src="http://123.57.37.211/cat.png" height="auto" width="auto"></body> </html> [root@lmr default]# 本机是另外一台WEB服务器IP192.168.1.83
访问测试面q.html(上面的页网代码)，测试结果如下：
图片服务器的404.html:
