Express路径在本地提供服务时有效，但一旦部署便会失败

const express = require('express');
const app = express();

// 本地路径配置
const localPath = '/local/path';
// 生产环境路径配置
const productionPath = '/production/path';

const pathToUse = process.env.NODE_ENV === 'production' ? productionPath : localPath;

app.get(pathToUse, (req, res) => {
  res.send('Path matched!');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

const express = require('express');
const path = require('path');
const app = express();

// 设置静态资源路径
app.use(express.static(path.join(__dirname, 'public')));

app.get('/static/path', (req, res) => {
  res.sendFile(path.join(__dirname, 'public', 'index.html'));
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

server {
  listen 80;
  server_name yourdomain.com;

  location / {
    proxy_pass http://localhost:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}
