nginx 和 nodejs 从动态文件夹中提供图像 [英] nginx and nodejs serve images from dynamic folder

问题描述

我有这个 nginx 设置:

Hi i have this nginx setup:

server {
listen 80;
server_name xxxxxx.xx www.xxxxxxx.xx;
root /home/xxxx/public_html;

location / {
    proxy_pass http://127.0.0.1:3000;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $connection_upgrade;
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host;
    #proxy_redirect off; 
    #proxy_cache_bypass $http_upgrade;
  }
}

我的应用程序在上传/用户中创建文件夹，然后是用户的 ID，然后将图像存储到其中.每个用户在uploads/user/xxxx 中都有自己的文件夹.

My app creates folders inside the uploads/user followed by the user's ID and then stores images into it. Every user have his own folder inside uploads/user/xxxx.

例如

/uploads/user/5878db663e67e3535a47c638/1085.github-logo.png

该应用在浏览器中运行良好，但当用户上传图像时，它无法显示，因此 404 上升.

The app works fine in browser but when the user uploads the image it cannot be displayed so a 404 rises.

我能做什么?

推荐答案

您可以使用 try_files 来提供静态内容(如果存在)，否则请遵循 NodeJS:

You can use try_files to serve up static content (if it exists) and otherwise defer to NodeJS:

root /home/xxxx/public_html;

location / {
    try_files $uri $uri/ @proxy;
}
location @proxy {
    proxy_pass http://127.0.0.1:3000;
    ...
}
