Reverse Proxy on nginx and nodejs

nginx:

location / {
            root /home/web2_root;
            proxy_pass http://127.0.0.1:8080/web/;
            proxy_read_timeout 300;
            proxy_connect_timeout 300;
            proxy_redirect     off;

            proxy_set_header   X-Forwarded-Proto $scheme;
            proxy_set_header   Host              $http_host;
            proxy_set_header   X-Real-IP         $remote_addr;
        }

node.js:

const express = require('express');
const proxy = require('http-proxy-middleware');

const app = express();
app.use('/static', express.static(`${__dirname}/static`));
app.use('/v2', proxy({
  target: 'http://api.douban.com',
  changeOrigin: true,
}));

app.get('/*', (req, res) => {
  res.sendFile(`${__dirname}/index.html`);
});
app.listen(8000);
