Python SPDY library on top of Spdylay C library

Project Description

Python-spdylay is a Python SPDY library on top of Spdylay C library. It supports SPDY/2 and SPDY/3 protocol.

It does not perform any I/O operations. When the library needs them, it calls the callback functions provided by the application. It also does not include any event polling mechanism, so the application can freely choose the way of handling events.

It provides almost all API Spdylay provides with Pythonic fashion.

The core library API works with Python 2 and 3. But ThreadedSPDYServer requires Python 3.3 because it uses TLS NPN extension.


First install Spdylay library. You can grab a source distribution from download page or clone git repository.

See Spdylay documentation for the required packages and how to build Spdylay from git repository.

After Spdylay is installed, run build_ext command to build extension module:

$ python build_ext

If you installed Spdylay library in other than standard location, use --include-dirs and --library-dirs to specify header file and library locations respectively.


See python-spdylay documentation.


Here is a simple SPDY server:

#!/usr/bin/env python

# The example SPDY server. Python 3.3 or later is required because TLS
# NPN is used in spdylay.ThreadedSPDYServer. Put private key and
# certificate file in the current working directory.

import spdylay

# private key file
# certificate file

class MySPDYRequestHandler(spdylay.BaseSPDYRequestHandler):

    def do_GET(self):
        self.send_header('content-type', 'text/html; charset=UTF-8')

        content = '''\
<head><title>SPDY FTW</title></head>
<h1>SPDY FTW</h1>
<p>The age of HTTP/1.1 is over. The time of SPDY has come.</p>


if __name__ == "__main__":
    HOST, PORT = "localhost", 3000

    server = spdylay.ThreadedSPDYServer((HOST, PORT),

Here is a simple SPDY client:

#!/usr/bin/env python

# The example SPDY client.  You need Python 3.3 or later because we
# use TLS NPN.
# Usage: URL...
import sys
import spdylay

class MyStreamHandler(spdylay.BaseSPDYStreamHandler):
    def on_header(self, nv):
        for k, v in nv:
            sys.stdout.write('{}: {}\n'.format(k, v))

    def on_data(self, data):

    def on_close(self, status_code):
        sys.stdout.write('Stream#{} closed\n'.format(self.stream_id))

if __name__ == '__main__':
    uris = sys.argv[1:]
    spdylay.urlfetch(uris, MyStreamHandler)
