This documentation is for an old version of IPython. You can find docs for newer versions here.

Module: html.base.zmqhandlers

Tornado handlers for WebSocket <-> ZMQ sockets.

Authors:

• Brian Granger

2 Classes

class IPython.html.base.zmqhandlers.ZMQStreamHandler(application, request, **kwargs)

Bases: tornado.websocket.WebSocketHandler

allow_draft76()

Allow draft 76, until browsers such as Safari update to RFC 6455.

This has been disabled by default in tornado in release 2.2.0, and support will be removed in later versions.

check_origin(origin)

Check Origin == Host or Access-Control-Allow-Origin.

Tornado >= 4 calls this method automatically, raising 403 if it returns False. We call it explicitly in open on Tornado < 4.

clear_cookie(*args, **kwargs)

meaningless for websockets

class IPython.html.base.zmqhandlers.AuthenticatedZMQStreamHandler(application, request, **kwargs)

Bases: IPython.html.base.zmqhandlers.ZMQStreamHandler, IPython.html.base.handlers.IPythonHandler

set_default_headers()

Undo the set_default_headers in IPythonHandler

which doesn’t make sense for websockets
