如何在node.js中发出HTTPS POST请求？

const https = require('https');
const querystring = require('querystring');

const postData = querystring.stringify({
  'key1': 'value1',
  'key2': 'value2'
});

const options = {
  hostname: 'api.example.com',
  port: 443,
  path: '/endpoint',
  method: 'POST',
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded',
    'Content-Length': Buffer.byteLength(postData)
  }
};

const req = https.request(options, (res) => {
  console.log(`状态码: ${res.statusCode}`);
  
  res.on('data', (chunk) => {
    console.log(`响应主体: ${chunk}`);
  });
  
  res.on('end', () => {
    console.log('响应已完成');
  });
});

req.on('error', (e) => {
  console.error(`请求遇到问题: ${e.message}`);
});

req.write(postData);
req.end();
