const http = require('http');
var querystring = require('querystring');
const postData = JSON.stringify(
    {

  console.log(postData);
  
  const options = {
    hostname: '',
    port: 8089,
    path: '',
    method: 'POST',
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded',
      'Content-Length': Buffer.byteLength(postData)
    }
  };
  
  const req = http.request(options, (res) => {
    console.log(`: ${res.statusCode}`);
    console.log(`: ${JSON.stringify(res.headers)}`);
    res.setEncoding('utf8');
    res.on('data', (chunk) => {
      console.log(`: ${chunk}`);
    });
    res.on('end', () => {
      console.log('');
    });
  });
  
  req.on('error', (e) => {
    console.error(`: ${e.message}`);
  });
  
  // 
  req.write(postData);
  req.end();

finally I sent the past in this way
