python-spdy

python-spdy is a simple SPDY v2/v3 parser/(de)muxer for Python 2.6 or newer. Python 3 is supported.

Usage

import spdy.context, spdy.frames

#with an existing socket or something
context = spdy.context.Context(side=spdy.context.SERVER, version=2)

while True:
	data = sock.recv(1024)
	if not data:
		break

	context.incoming(data)

	while True:
		frame = context.get_frame()
		if not frame: 
			break
		
		if isinstance(frame, spdy.frames.Ping):
			pong = spdy.frames.Ping(frame.ping_id)
			context.put_frame(pong)

	outgoing = context.outgoing()
	if outgoing:
		sock.sendall(outgoing)	

Installation

requires:

pip install bitarray

then:

python setup.py install

Note: To use this library for I/O networking, the SPDY protocol usually needs below an SSL layer with NPN (Next-Protocol Negotiation) support. Python 3.3+ does support ssl.set_npn_protocols() call, only for environments running OpenSSL 1.0.1+.

  If you are not running Python 3.3+ over OpenSSL 1.0.1+, you can use 
  the tlslite module [1][2], from Python 2.6/2.7 instead. 
  
  Take a look at the /examples directory for client and server SPDY examples.
