Nginx 防盗链：三行规则保住你的图片带宽_我的网站

冰与火之歌

一 | (ECNS) -- Shanghai is accelerating its digital transformation under a new blueprint for the 15th Five-Year Plan period (2026-2030), with a focus on breakthroughs in 6G technology and next-generation digital infrastructure. The city plans to advance the commercial deployment of 6G and develop intelligent experimental networks. It will also expand 5G-A coverage across a wide range of scenarios and strengthen links with the "Thousand Sails Constellation" satellite internet project. Beyond communications infrastructure, Shanghai aims to develop into a leading international data processing hub. The city plans to build advanced data centers in key areas including Lingang and Hongqiao, while facilitating cross-border data flows through a more practical negative-list system. The measures are intended to make international data exchanges more secure and efficient for multinational companies and other global businesses. The plan also places greater emphasis on high-performance computing, including the integration of AI computing and supercomputing resources into a unified service platform. At the same time, Shanghai will deepen digital cooperation with Singapore and BRICS countries, further strengthening its role as a gateway connecting China with the global digital economy. The strategy underscores China's push to lead the development of next-generation technologies while expanding international cooperation in the digital sector.

　一键部署OpenClaw 月底一看流量报表，消耗翻倍，查访问日志发现一堆陌生域名在直接引用你站上的图。

三 | 别人家的页面加载你付钱买的带宽，这买卖不能做。防盗链Nginx原生支持，就是referer模块。原理一句话：浏览器请求图片时会带上Referer头标明来路，不是你允许的来路就直接拒掉或换图。核心就三行。

location ~* \.(jpg|jpeg|png|gif|webp|mp4)$ {    valid_referers none blocked server_names    *.yoursite.com yoursites-cdn.com;    if ($invalid_referer) {    return 403; # 也可以 return 302 到一张提示图    }    }

none表示空Referer放行——用户直接在地址栏敲图片URL、部分邮件客户端都不带Referer，一刀切拦掉会误伤真人。blocked是Referer被代理或防火墙抹掉的情况，也建议放行。

四 | 真正的目标只有那些站外页面。

五 | 微信、QQ、微博这些平台的抓图请求Referer各不相同，如果你希望图片能在社交分享卡片里显示，把对应域名加进valid_referers列表。

六 | 改完nginx -t测试、nginx -s reload生效，然后用一个在线防盗链检测工具或在自己另一个域名挂个img标签试试，403就是生效了。顺带说一句： Referer是可以伪造的，防得住君子防不住定向爬虫。真要保护付费内容，走签名URL（secure_link模块）或者直接挪到对象存储的私有桶。对绝大多数个人站长，referer这套已经能省下可观的带宽钱。数据来源：nginx.org官方文档 ngx_http_referer_module 模块说明
