如何将数据从托管在Heroku上的Node.js应用程序发送到托管在完全独立的(Cpanel)服务器上的PHP文件？

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

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

const postData = querystring.stringify(data);

const options = {
  hostname: 'your-cpanel-server.com',
  port: 80,
  path: '/path/to/your/php/file.php',
  method: 'POST',
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded',
    'Content-Length': Buffer.byteLength(postData)
  }
};

const req = http.request(options, (res) => {
  console.log(`STATUS: ${res.statusCode}`);
  console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
  res.setEncoding('utf8');
  res.on('data', (chunk) => {
    console.log(`BODY: ${chunk}`);
  });
  res.on('end', () => {
    console.log('No more data in response.');
  });
});

req.on('error', (e) => {
  console.error(`problem with request: ${e.message}`);
});

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

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
  $key1 = $_POST['key1'];
  $key2 = $_POST['key2'];

  // 处理接收到的数据
  echo "Received data: key1 = $key1, key2 = $key2";
}
?>
