Adding WSS to Websocket/Autobahn/WAMP/Twisted

问题

There doesn't seem to be much out there right now on how to properly add WSS support to an Autobahn/Twisted setup. I'm starting with the Crossbar serial2ws example, which shows a WS-based connection between frontend and backend.

I'd like to know how to adapt the serial2ws example for an SSL connection.

I changed:

# serial2ws.py
router = args.router or 'ws://localhost:8080'
to
router = args.router or 'wss://localhost:8080'

And on the website JS:

connection = new autobahn.Connection({
  url: (document.location.protocol === "http:" ? "ws:" : "wss:") + "//" + ip + ":" + port,
  realm: 'realm1',
  ...
})

But, when I try to connect, it fails with:

WebSocket connection to 'wss://192.168.0.12:8080/' failed: Error in connection establishment: net::ERR_CONNECTION_CLOSED

The Python server logs:

2016-06-30 16:52:57-0400 [-] Log opened.
2016-06-30 16:52:57-0400 [-] Using Twisted reactor <class

To be clear, when the "wss" instances above are reverted to the original "ws", everything works.

Also tried:

Adding to serial2ws.py:

contextFactory = ssl.DefaultOpenSSLContextFactory('/root/keys/server.key', '/root/keys/server.crt')

# Change
reactor.listenTCP(args.web, Site(File(".")))
# to
reactor.listenSSL(args.web, Site(File(".")), contextFactory)
