NextJS应用部署后偶现返回静态内容文本而非HTML的问题求助

我将采用App目录的Next.js 13.4.5应用部署到DigitalOcean应用平台后，偶尔会收到包含static内容的文本响应，而非预期的HTML页面。返回的内容示例如下：

1:HL["/_next/static/media/7777133e901cd5ed-s.p.woff2",{"as":"font","type":"font/woff2"}]
2:HL["/_next/static/media/916d3686010a8de2-s.p.woff2",{"as":"font","type":"font/woff2"}]
3:HL["/_next/static/media/9a881e2ac07d406b-s.p.woff2",{"as":"font","type":"font/woff2"}]
4:HL["/_next/static/media/c04551857776278f-s.p.woff2",{"as":"font","type":"font/woff2"}]
5:HL["/_next/static/media/d869208648ca5469-s.p.woff2",{"as":"font","type":"font/woff2"}]
6:HL["/_next/static/css/23bb12ed1ea5f9c7.css",{"as":"style"}]
0:[[["",{"children":["__PAGE__",{}]},"$undefined","$undefined",true],"$L7",[[["$","link","0",{"rel":"stylesheet","href":"/_next/static/css/23bb12ed1ea5f9c7.css","precedence":"next"}]],["$L8",["$","meta",null,{"name":"next-size-adjust"}]]]]]

本地环境无法复现该问题，更换Next.js版本也没能解决这个异常。

可能的解决方法 #

• 检查DigitalOcean缓存配置：确保平台的CDN没有错误缓存React Server Components（RSC）的序列化响应。需要为Next.js的路由设置正确的缓存策略，避免将RSC数据当作HTML缓存。
• 验证Next.js输出模式：确认部署时使用output: 'standalone'配置（Next.js 13+推荐），确保静态资源与服务端响应的分离逻辑正常。
• 检查请求头：确认客户端请求的Accept头包含text/html，如果请求头异常，Next.js可能返回RSC序列化数据而非渲染后的HTML。
• 清理部署缓存：重新部署应用时，清理DigitalOcean平台的构建缓存，避免旧产物残留导致的响应混淆。
• 排查自定义中间件：如果应用中有自定义中间件，检查是否错误修改了请求或响应头，导致服务端返回错误的内容类型。
