nginx设置图片防盗链

编辑Nginx配置  可以用域名也可以用ip

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        valid_referers none blocked b2b_ecae.cn;
        if ($invalid_referer)
        {
            return 403;
        }
        expires      30d;
    }

valid_referers none blocked 后面的域名可以是多个  ip和域名是有区别的  如果域名下外链的图片 要填写域名

重启Nginx即可

测试

[root@localhost ~]# curl -I http://b2b_ecae.cn/test.jpg
HTTP/1.1 200 OK

或者下面这样测试  html文件放在另外一个非b2b_ecae.cn的域名下
