js不同ip访问不同页面

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

app.use((req, res, next) => {
  const ip = req.ip; // 获取客户端IP地址

  // 这里可以根据IP地址进行判断
  if (ip === '127.0.0.1') {
    res.redirect('/local-page');
  } else if (ip === '192.168.1.1') {
    res.redirect('/remote-page');
  } else {
    res.redirect('/default-page');
  }
});

app.get('/local-page', (req, res) => {
  res.send('This is the local page');
});

app.get('/remote-page', (req, res) => {
  res.send('This is the remote page');
});

app.get('/default-page', (req, res) => {
  res.send('This is the default page');
});

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

fetch('/get-ip')
  .then(response => response.json())
  .then(data => {
    const ip = data.ip;
    if (ip === '127.0.0.1') {
      window.location.href = '/local-page';
    } else if (ip === '192.168.1.1') {
      window.location.href = '/remote-page';
    } else {
      window.location.href = '/default-page';
    }
  });

const ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;
