如何在Node中获取HTTPS网站的HTML源代码

const https = require('https');

const options = {
  hostname: 'example.com',
  port: 443,
  path: '/',
  method: 'GET'
};

const req = https.request(options, (res) => {
  let html = '';

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

  res.on('end', () => {
    console.log(html);
  });
});

req.on('error', (e) => {
  console.error(e);
});

req.end();
