内容注入

在 Nginx 在反向代理或 CDN 层做内容注入（content injection） 的典型需求，例如给网站自动插入监控脚本、统计代码、或 CSP 报告器脚本等。
可以实现，但需要明确一点：Nginx 本身不会修改 HTML 内容，除非你启用额外的模块或通过 Lua/NJS 扩展。
有几种常见方式可以实现在 HTML 页面中自动插入 <script> 标签：
| 方式 | 可行性 | 性能 | 说明 |
|---|---|---|---|
① 使用 sub_filter 模块 | 简单直接 | 很快 | 适合替换或插入少量静态脚本 |
② 使用 ngx_http_lua_module | 灵活 | 中等 | 可动态判断 URL、User-Agent、域名等 |
③ 使用 njs（JavaScript for Nginx） | 较灵活 | 中等 | 官方支持的 JavaScript 脚本语言 |
| ④ 使用 CDN（如 Cloudflare Workers） | 最推荐 | 较优 | 可在边缘节点动态修改 HTML |
sub_filter
如果只是想在 HTML 中的特定位置（例如 </head> 前）插入一段脚本，ngx_http_sub_module 足够用了。
启用模块（大多数 Nginx 已内置）
先确认模块是否可用：
nginx -V 2>&1 | grep sub如果看到 --with-http_sub_module，说明已启用。
server {
listen 80;
server_name example.com;
location / {
proxy_pass http://127.0.0.1:8080;
sub_filter '</head>' '<script src="https://xxx.xxxx/xxx.js"></script></head>';
sub_filter_once on; # 只替换第一次出现的 </head>
sub_filter_types text/html;
}
}原理：
- 当 Nginx 代理后端返回 HTML 时，它会扫描响应体，将匹配到的
</head>替换为你的脚本+原文本。 - 这种方法最适合简单静态注入，比如插入统计脚本或监控脚本。
注意：
sub_filter仅对文本类型有效 (text/html)。- 对 gzip 压缩的响应需先禁用压缩或解压后再替换。
可在上方配置中添加：
proxy_set_header Accept-Encoding "";防止后端发送 gzip。
Lua 注入
如果需要：
- 只给特定 URL 注入；
- 动态生成脚本内容；
- 根据 Cookie / Header 条件决定是否注入；
可以使用 ngx_http_lua_module。
lua_need_request_body on;
server {
listen 80;
server_name example.com;
location / {
proxy_pass http://127.0.0.1:8080;
body_filter_by_lua_block {
local chunk = ngx.arg[1]
if ngx.ctx.injected then
ngx.arg[1] = chunk
return
end
if chunk and string.find(chunk, "</head>") then
chunk = string.gsub(chunk, "</head>", '<script src="https://xxx.xx/xx.js"></script></head>')
ngx.ctx.injected = true
end
ngx.arg[1] = chunk
}
}
}这段脚本：
- 会扫描返回的 HTML 块；
- 找到
</head>时插入<script>； - 可加入逻辑判断（例如只在某域名、某路径下生效）。
njs（官方 JS 模块）
js_import main from /etc/nginx/html/inject.js;
server {
listen 80;
location / {
proxy_pass http://127.0.0.1:8080;
js_body_filter main.inject;
}
}/etc/nginx/html/inject.js 内容：
function inject(r, data, flags) {
if (data.indexOf('</head>') !== -1) {
data = data.replace('</head>', '<script src="https://xxx.xxx.xxx/xx.js"></script></head>');
}
return data;
}
export default { inject };CDN/边缘层注入
如果网站有 CDN 层（例如 Cloudflare、Vercel、Netlify Edge Functions 等），可以直接在边缘节点处理响应 HTML：
示例（Cloudflare Workers）：
export default {
async fetch(request, env, ctx) {
let res = await fetch(request)
let html = await res.text()
html = html.replace('</head>', '<script src="https://monitor.yumeng.icu/track.js"></script></head>')
return new Response(html, res)
}
}这种方式无需改服务器配置，还能分发到全球节点，非常适合监控脚本注入。
注意事项
HTTPS 混合内容
如果你的站是 HTTPS，注入的脚本也必须是 HTTPS。
安全性
小心 XSS 风险，不要注入任何未经验证的外部脚本。
gzip 问题
对压缩过的响应，需要禁用压缩或先解压再替换。
缓存影响
CDN 或浏览器缓存可能导致脚本注入失效，要配置合适的缓存策略。
