如何让https.get请求将请求内的数据赋值给请求外的变量？

const https = require('https');

function getDataFromHttps(url) {
  return new Promise((resolve, reject) => {
    https.get(url, (res) => {
      let data = '';

      res.on('data', (chunk) => {
        data += chunk;
      });

      res.on('end', () => {
        resolve(data);
      });
    }).on('error', (error) => {
      reject(error);
    });
  });
}

// 使用示例
const url = 'https://example.com/api/data';
let responseData;

getDataFromHttps(url)
  .then((data) => {
    responseData = data;
    console.log(responseData);
  })
  .catch((error) => {
    console.error(error);
  });
