`req.getHeaders()` does not return values set using "rawHeaders" array

Inizia dal punto di ingresso delle richieste di node:http e traccia il modo in cui viene memorizzato l’array options.headers prima che vengano chiamati getHeaders(), getHeaderNames() e getRawHeaderNames(). Riproduci l’esempio, quindi verifica che questi metodi riportino gli header in modo coerente con le opzioni in forma di oggetto, preservando al contempo gli header della richiesta emessi.

What steps will reproduce the bug?

Headers set using the message.rawHeaders format are not available on the request's getHeaders() method

import { get } from 'node:http'

const request = get(
  'http://localhost:3000',
  {
    headers: ['foo', 'bar', 'baz', 'qux']
  },
  (res) => {
    let data = ''

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

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

request.on('error', () => {})

console.log(request.getHeaders()) // [Object: null prototype] {}
console.log(request.getHeaderNames()) // []
console.log(request.getRawHeaderNames()) // []
console.log(request._header) // GET / HTTP/1.1\r\nfoo: bar\r\nbaz: qux\r\nConnection: keep-alive

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

One would expect req.getHeaders() (and friends) to return a consistent value, whether an object or an array was passed as argument.

What do you see instead?

req.getHeaders() appears to be empty when request options are built using an array notation.
