http2: code examples does not work on Windows with port 80

Version: master with http2: Introducing http/2 #14239
Platform: Windows 7 x 64
Subsystem: http2

The first examples from "Core API" chapter do not work properly on Windows with port 80 but work with other ports.

I've added some output and repeated request for easier debugging. Here are the code and output with port 81:

Server:

const http2 = require('http2');

// Create a plain-text HTTP/2 server
const server = http2.createServer();

server.on('stream', (stream, headers) => {
  console.log('headers: ', headers);
  stream.respond({
    'content-type': 'text/html',
    ':status': 200
  });
  stream.end('<h1>Hello World</h1>');
});

server.listen(81);

Client:

const http2 = require('http2');

function test() {
  const client = http2.connect('http://localhost:81');

  const req = client.request({ ':path': '/' });

  req.on('response', (headers) => {
    console.log(headers[':status']);
    console.log(headers['date']);
  });

  let data = '';
  req.setEncoding('utf8');
  req.on('data', (d) => data += d);
  req.on('end', () => { client.destroy(); console.log('data: ', data); });
  req.end();
}

setInterval(test, 2000);

Server output:

(node:7960) ExperimentalWarning: The http2 module is an experimental API.
headers:  { ':scheme': 'http',
  ':authority': 'localhost:81',
  ':method': 'GET',
  ':path': '/' }
headers:  { ':scheme': 'http',
  ':authority': 'localhost:81',
  ':method': 'GET',
  ':path': '/' }
headers:  { ':scheme': 'http',
  ':authority': 'localhost:81',
  ':method': 'GET',
  ':path': '/' }

Client output:

(node:6732) ExperimentalWarning: The http2 module is an experimental API.
200
Sun, 16 Jul 2017 13:40:19 GMT
data:  <h1>Hello World</h1>
200
Sun, 16 Jul 2017 13:40:21 GMT
data:  <h1>Hello World</h1>
200
Sun, 16 Jul 2017 13:40:23 GMT
data:  <h1>Hello World</h1>

When I change the port in both examples into 80, I get:
Server output:

(node:4792) ExperimentalWarning: The http2 module is an experimental API.

Client output:

(node:1784) ExperimentalWarning: The http2 module is an experimental API.

FWIW, I've tried to see what was going on with TCPView:

The first two is the Server, the last two are Client requests and they are trying to connect the 443 port.

Will look into it! Thank you! :-)

@vsemozhetbyt

ping @vsemozhetbyt — is this still the case for you?

@apapirovski

@apapirovski Yes, the behavior from the first post remains with Node.js 8.7.0 or the last nightly build.

@vsemozhetbyt

@vsemozhetbyt Could you try the same with http or net when you have a moment?

@apapirovski

@apapirovski Let me know if I use wrong test examples.
Server:

'use strict';

const http = require('http');

const hostname = 'localhost';
const port = 81;

const server = http.createServer((req, res) => {
  console.log(req.headers);

  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World\n');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

Client:

'use strict';

const http = require('http');

http.get({
  hostname: 'localhost',
  port: 81,
  path: '/',
}, (res) => {
  console.log(res.headers);
});

Port 81, Server:

Server running at http://localhost:81/
{ host: 'localhost:81', connection: 'close' }

Port 81, Client:

{ 'content-type': 'text/plain',
  date: 'Thu, 19 Oct 2017 12:30:28 GMT',
  connection: 'close',
  'content-length': '12' }

Port 80, Server:

Server running at http://localhost:80/
{ host: 'localhost', connection: 'close' }

Port 80, Client:

{ 'content-type': 'text/plain',
  date: 'Thu, 19 Oct 2017 12:31:35 GMT',
  connection: 'close',
  'content-length': '12' }

Thanks so much for testing http too! I think I have a rough lead on what's going on. Will update later tonight when I have a moment to confirm whether I'm right or not.
