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;

#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 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：

[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：
