# Getting Started | ||
|
||
This guide explains how to use the `protocol-http2` gem to implement a basic HTTP/2 client. | ||
|
||
## Installation | ||
|
||
Add the gem to your project: | ||
|
||
``` bash | ||
$ bundle add protocol-http2 | ||
``` | ||
|
||
## Usage | ||
|
||
This gem provides a low-level implementation of the HTTP/2 protocol. It is designed to be used in conjunction with other libraries to provide a complete HTTP/2 client or server. However, it is straight forward to give examples of how to use the library directly. | ||
|
||
### Client | ||
|
||
Here is a basic HTTP/2 client: | ||
|
||
``` ruby | ||
require 'async' | ||
require 'async/io/stream' | ||
require 'async/http/endpoint' | ||
require 'protocol/http2/client' | ||
|
||
Async do | ||
endpoint = Async::HTTP::Endpoint.parse("https://www.google.com/search?q=kittens") | ||
|
||
peer = endpoint.connect | ||
|
||
puts "Connected to #{peer.inspect}" | ||
|
||
# IO Buffering: | ||
stream = Async::IO::Stream.new(peer) | ||
|
||
framer = Protocol::HTTP2::Framer.new(stream) | ||
client = Protocol::HTTP2::Client.new(framer) | ||
|
||
puts "Sending connection preface..." | ||
client.send_connection_preface | ||
|
||
puts "Creating stream..." | ||
stream = client.create_stream | ||
|
||
headers = [ | ||
[":scheme", endpoint.scheme], | ||
[":method", "GET"], | ||
[":authority", "www.google.com"], | ||
[":path", endpoint.path], | ||
["accept", "*/*"], | ||
] | ||
|
||
puts "Sending request on stream id=#{stream.id} state=#{stream.state}..." | ||
stream.send_headers(headers, Protocol::HTTP2::END_STREAM) | ||
|
||
puts "Waiting for response..." | ||
$count = 0 | ||
|
||
def stream.process_headers(frame) | ||
headers = super | ||
puts "Got response headers: #{headers} (#{frame.end_stream?})" | ||
end | ||
|
||
def stream.receive_data(frame) | ||
data = super | ||
|
||
$count += data.scan(/kittens/).count | ||
|
||
puts "Got response data: #{data.bytesize}" | ||
end | ||
|
||
until stream.closed? | ||
frame = client.read_frame | ||
end | ||
|
||
puts "Got #{$count} kittens!" | ||
|
||
puts "Closing client..." | ||
client.close | ||
end | ||
``` |
