在 Nginx 的反向代理中为特定静态文件添加缓存？

Question

我想在客户端浏览器上使用 nginx 缓存单页应用程序的 js 和 css 文件。当我尝试当前注释掉的块时，指定的文件有 404 响应。尝试将块放入 location / { 块中，但发生了同样的错误。有人知道怎么修这个东西吗？帮助表示赞赏。

您得到 404，因为您没有提供任何服务，请将 proxy_pass 添加到前端应用程序

     location ~* \.(?:css|js)$ {
       expires 1d;  
        add_header Vary Accept-Encoding;
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
        add_header Cache-Control private;
        proxy_pass http://localhost:3000;
     }
