处理多个http响应并在单个方法中一次返回它们

// 前端示例代码
function fetchMultipleUrls(urls) {
  const requests = urls.map(url => fetch(url));
  return Promise.all(requests)
    .then(responses => Promise.all(responses.map(response => response.json())))
    .catch(error => console.log(error));
}

const urls = ['https://api.example.com/data1', 'https://api.example.com/data2'];
fetchMultipleUrls(urls)
  .then(data => console.log(data))
  .catch(error => console.log(error));

// 后端示例代码（使用Express）
const express = require('express');
const axios = require('axios');
const app = express();

app.get('/data', async (req, res) => {
  try {
    const responses = await Promise.all([
      axios.get('https://api.example.com/data1'),
      axios.get('https://api.example.com/data2')
    ]);
    const data = responses.map(response => response.data);
    res.json(data);
  } catch (error) {
    console.log(error);
    res.status(500).json({ error: 'Internal server error' });
  }
});

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