如何在不加载页面的情况下使用NodeJS发送POST请求和返回响应

const http = require('http');

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

const options = {
  hostname: 'api.example.com',
  port: 80,
  path: '/endpoint',
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Content-Length': Buffer.byteLength(postData)
  }
};

const req = http.request(options, (res) => {
  let data = '';

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

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

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

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

const axios = require('axios');

const postData = {
  key1: 'value1',
  key2: 'value2'
};

axios.post('http://api.example.com/endpoint', postData)
  .then((response) => {
    console.log(response.data);
  })
  .catch((error) => {
    console.error(error);
  });
