This works a bit differently than python websockify implementation
since the server either runs in HTTP or in HTTPS and both web and
websocket servers only support the same mode. Specifying the --cert
parameter activates encrypted HTTPS/WSS mode.
This version requires a patched version of einaros/ws that can be
found here: https://github.com/kanaka/ws You can use the patched
version like this:
cd websockify/other
git clone https://github.com/kanaka/ws
npm link ./ws
Once the upstream 'ws' module supports subprotocol negotiation then
this will no longer be necessary.
Changes:
- Adds support for binary data and subprotocol negotiation of 'base64'
vs 'binary' with 'binary' preferred if the client offers it.
- Add client address to log messages.
- Close the target when the client closes.
- Catch errors when we try and send to a client that is no longer
connected.
It's probably broken and it's definitely still messy in several ways,
but basic tests work with Chrome.
Several other C websockify cleanups:
- Remove most of the non-thread safe global variable usage (still
a little bit that could be fixed so that threading would be easier).
- Remove wswrapper. It is unmaintained, out of date, and never worked
well anyways (since it really needed a way to do asynchronous queued
work but it was running in another process context making that
hard).
- Use md5 routines from openssl.
- Remove md5.c and md5.h since no longer needed.
Thanks to https://github.com/dew111 for spurring me on to get this
done by writing code. I didn't end up using much his forked code, but
having something there goaded me enough to just get it working.
