如何一次获取监听http.get的两个观察量的值？

const http = require('http');

function getObservables() {
  return new Promise((resolve, reject) => {
    const observable1 = new Promise((resolve, reject) => {
      http.get('http://example.com/observable1', (res) => {
        let data = '';
        res.on('data', (chunk) => {
          data += chunk;
        });
        res.on('end', () => {
          resolve(data);
        });
      }).on('error', (err) => {
        reject(err);
      });
    });

    const observable2 = new Promise((resolve, reject) => {
      http.get('http://example.com/observable2', (res) => {
        let data = '';
        res.on('data', (chunk) => {
          data += chunk;
        });
        res.on('end', () => {
          resolve(data);
        });
      }).on('error', (err) => {
        reject(err);
      });
    });

    Promise.all([observable1, observable2])
      .then((values) => {
        resolve(values);
      })
      .catch((err) => {
        reject(err);
      });
  });
}

getObservables()
  .then((values) => {
    console.log('Observable 1:', values[0]);
    console.log('Observable 2:', values[1]);
  })
  .catch((err) => {
    console.error('Error:', err);
  });
