consume-http-header

Consume an HTTP request or response stream until all headers have been read.

Leaves the stream ready to be consumed from the start of the HTTP body.

Installation

npm install consume-http-header --save

Usage

var net = require('net')
var consume = require('consume-http-header')

var socket = net.connect({ host: 'example.com', port: 80 })

socket.write('GET / HTTP/1.1\r\n')
socket.write('Host: example.com\r\n')
socket.write('\r\n')

consume(socket, function (err, req) {
  if (err) throw err

  console.log('New HTTP response:', req.method, req.url)

  console.log('Headers:')
  consooe.log(req.headers)

  console.log('Body:')
  socket.pipe(process.stdout)
})

API

consume(stream, callback)

The module exposes a single function which takes 3 arguments:

• stream - The stream to consume
• callback - The callback will be called when a complete set of HTTP headers have been read from the stream. The headers will be given as the second argument. An error is given as the first argument if the stream either ends before all the headers have been read or if the stream emits an error

Consuming the HTTP body

When the callback is called, continue consuming the stream to get the body of the request. But be aware of the following gotchas:

• If the stream is reused for multiple requests and responses, be aware of when the body ends
• If req.headers['transfer-encoding'] === 'chunked', be aware that the body is using Chunked Transfer Coding and you have to decode it accordingly. Decoding Chunked Transfer Coding is outside the scope of this module
