socket.write('Host: example.com\r\n')
socket.write('\r\n')

consume(socket, function (err, req) {

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
