@luelueking

const http2 = require('http2');
const querystring = require('querystring');

const client = http2.connect('http://localhost:8088');
const data = querystring.stringify({ key1: 'value1', key2: 'value2' });

const req = client.request({
  ':method': 'POST',
  ':path': '/api/echo',
  'content-type': 'application/x-www-form-urlencoded',
  'content-length': Buffer.byteLength(data)
});

req.setEncoding('utf8');
req.write(data);

let response = '';
req.on('data', (chunk) => { response += chunk; });
req.on('end', () => {
  console.log('Response:', response);
  client.close();
});
req.end();
