在Ruby中发送HTTP / 2 POST请求 [英] Sending HTTP/2 POST request in Ruby

问题描述

我正在尝试使用新的 Apple推送通知 API，基于 HTTP / 2 。

I am trying to use the new Apple Push Notification API, which is based on HTTP/2.

我找到了 http-2 Ruby gem，但文档并不清楚如何作为客户端发出请求。

I found the http-2 Ruby gem, but the documentation isn’t clear about how to make requests as a client.

如何在Ruby / Rails中发出HTTP / 2请求？

推荐答案

有一个在中创建HTTP / 2客户端的示例这个档案。它可以适应这样的APN请求：

There is an example of creating HTTP/2 client in this file. It could be adapted to APN requests like this:

require 'socket'
require 'http/2'

payload = '{"foo":"bar"}'
device_token = '00fc13adff785122b4ad28809a3420982341241421348097878e577c991de8f0' # example
sock = TCPSocket.new('api.development.push.apple.com', 443)

conn = HTTP2::Client.new
conn.on(:frame) do |bytes|
  puts "Sending bytes: #{bytes.unpack("H*").first}"
  sock.print bytes
  sock.flush
end

stream = conn.new_stream

stream.on(:close) do
  sock.close
end

head = {
  ':scheme' => 'https',
  ':method' => 'POST',
  ':path' => "/3/device/#{device_token}",
  'apns-id' => '123e4567-e89b-12d3-a456-42665544000', # or you could omit this header
  'content-length' => payload.bytesize.to_s # should be less than or equal to 4096 bytes
}

puts 'Sending HTTP 2.0 request'
stream.headers(head, end_stream: false)
stream.data(payload)

while !sock.closed? && !sock.eof?
  data = sock.read_nonblock(1024)
  puts "Received bytes: #{data.unpack("H*").first}"

  begin
    conn << data
  rescue => e
    puts "Exception: #{e}, #{e.message} - closing socket."
    sock.close
  end
end
