Spdylay - SPDY C Library
|
|
========================
|
|
|
|
This is an experimental implementation of Google's SPDY protocol
|
|
version 2 in C.
|
|
|
|
The current status of development is in a beta stage now. As described
|
|
below, we can create SPDY client and server with the current Spdylay
|
|
API.
|
|
|
|
Build from git
|
|
--------------
|
|
|
|
Building from git is easy, but please be sure that at least autoconf 2.68 is
|
|
used.::
|
|
|
|
$ autoreconf -i
|
|
$ automake
|
|
$ autoconf
|
|
$ ./configure
|
|
$ make
|
|
|
|
Examples
|
|
--------
|
|
|
|
*examples* directory contains SPDY client and server implementation
|
|
using Spdylay. These programs are intended to make sure that Spdylay
|
|
API is acutally usable for real implementation and also for debugging
|
|
purposes. Please note that OpenSSL with `NPN
|
|
<http://technotes.googlecode.com/git/nextprotoneg.html>`_ support is
|
|
required in order to build and run these programs. At the time of
|
|
this writing, the Beta 2 of OpenSSL 1.0.1 supports NPN.
|
|
|
|
SPDY client is called ``spdycat``. It is a dead simple downloader like
|
|
wget/curl. It connects to SPDY server and gets resources given in the
|
|
command-line::
|
|
|
|
$ ./spdycat -vn https://www.google.com/
|

SPDY server is called ``spdyd``. It is a non-blocking server and only
|
|
serves static contents. It only speaks ``spdy/2``::
|
|
|
|
$ ./spdyd --htdocs=/your/htdocs/ -v 3000 server.key server.crt
|
|
The negotiated next protocol: spdy/2

|
Currently, ``spdyd`` needs ``epoll`` or ``kqueue``.
|
|
|
|
There is another SPDY server called ``spdynative``, which is
|
|
`node.native <https://github.com/d5/node.native>`_ style simple SPDY
|
|
server::
|
|
|
|
#include <iostream>
|
|
|
|
#include "spdy.h"
|
|
|
|
int main()
|
|
{
|
|
spdy server;
|
|
if(!server.listen("localhost", 8080, "server.key", "server.crt",
|
|
[](request& req, response& res) {
|
|
res.set_status(200);
|
|
res.set_header("content-type", "text/plain");
|
|
res.end("C++ FTW\n");
|
|
}))
|
|
return EXIT_FAILURE;
|
|
|
|
std::cout << "Server running at http://localhost:8080/" << std::endl;
|
|
return reactor::run(server);
|
|
}
|
|
|
|
Don't expect much from ``spdynative``. It is just an example and does
|
|
not support asynchronous I/O at all.
