How to decode socket response? - ruby

Question

I am try to decode socket response from web source, but I can to decode only 50% of message.
It looks strange, because it should be a full message decompress, if it can decompress some socket response, but maybe I wrong. Any help will be greatly appreciated!
require "faye/websocket"
require "eventmachine"
require "permessage_deflate"
require 'zlib'
require 'stringio'
EM.run do
ws = Faye::WebSocket::Client.new("wss://wss.winline.ru/data_ng?", [], :extensions => [PermessageDeflate])
ws.on :open do |event|
p [:open]
ws.send "lang"
ws.send "AQ=="
ws.send "data"
ws.send "WINLINE"
ws.send "getdate"
ws.send "no_fordata"
end
ws.on :message do |event|
gz = Zlib::GzipReader.new(StringIO.new(event.data.pack('C*')))
puts gz.read
end
ws.on :close do |event|
p [:close, event.code, event.reason]
ws = nil
end
end
I have receive the following data:
�$��$^���60.5
�$��$^��62.5'!�$i#�$^����31.5�I�$�6�$^���9.5�3�$^���11.5� �$^��10�3�$$W�$^����80:3ূ$�m���&ާ�$�m�id�rݧ�$�m�t
�$''�=�v�p��a��0ȣc�Cincinnati BearcatsDetroit Mercy Titans��}$1'':%���}$1''�G���}$1'n|
As u can see, some parts of the message are decodable and other is still not.
Without decompress, I have this msg from sock:
[242, 204, 179, 144, 33, 112, 239, 219, 8, 118, 124, 89, 134, 218, 170, 173, 183, 173, 126, 59, 167, 131, 63, 254, 48, 115, 255, 123, 7, 161, 157, 64, 184, 79, 95, 202, 7, 203, 254, 172, 245, 49, 72, 63, 3, 5, 128, 62, 243, 77, 202, 4, 219, 80, 245, 92, 169, 237, 174, 85, 242, 165, 252, 180, 73, 54, 149, 19, 245, 163, 88, 212, 49, 186, 65, 111, 156, 215, 136, 53, 70, 54, 205, 33, 147, 72, 255, 36, 246, 167, 135, 253, 65, 163, 224, 36, 28, 78, 38, 227, 165, 7, 191, 246, 98, 255, 235, 195, 126, 55, 101, 38, 246, 68, 188, 252, 63, 92, 112, 93, 239, 36, 118, 2, 0]
I think, this source are using pako to compress their data socket.
