js怎么取服务器时间

const express = require('express');
const app = express();
const port = 3000;

app.get('/api/time', (req, res) => {
  const serverTime = new Date();
  res.json({ time: serverTime });
});

app.listen(port, () => {
  console.log(`Server running at http://localhost:${port}`);
});

async function getServerTime() {
  try {
    const response = await fetch('http://localhost:3000/api/time');
    const data = await response.json();
    console.log('Server Time:', data.time);
  } catch (error) {
    console.error('Error fetching server time:', error);
  }
}

getServerTime();

const cors = require('cors');
app.use(cors());

fetch('http://localhost:3000/api/time', { timeout: 5000 })
  .then(response => response.json())
  .then(data => console.log('Server Time:', data.time))
  .catch(error => console.error('Error fetching server time:', error));
