1. 针对不同的文件类型

#Preventing hot linking of images and other file types
location ~* ^.+\.(gif|jpg|png|swf|flv|rar|zip)$ {
    valid_referers none blocked server_names *.xtgly.com xtgly.com http://localhost baidu.com;
    if ($invalid_referer) {
        rewrite ^/ http://www.xtgly.com/images/default/logo.gif;
        # return 403;
    }
}

2. 针对不同的目录

location /img/ {
    root /data/www/wwwroot/bbs/img/;
    valid_referers none blocked server_names *.xtgly.com http://localhost baidu.com;
    if ($invalid_referer) {
        rewrite ^/ http://www.xtgly.com/images/default/logo.gif;
        #return 403;
    }
}

3. 同实现防盗链和expires的方法

#Preventing hot linking of images and other file types
location ~* ^.+\.(gif|jpg|png|swf|flv|rar|zip)$ {
    valid_referers none blocked server_names *.xtgly.com xtgly.com http://localhost ;
    if ($invalid_referer) {
        rewrite ^/ http://www.xtgly.com/images/default/logo.gif;
    }
    access_log off;
    root /data/www/wwwroot/bbs;
    expires 1d;
    break;
}
