===============
|

Here is a `socket.io <http://socket.io>`_ client library for Python. You can use it to write test code for your socket.io server.
|
||||
Here is a socket.io_ client library for Python. You can use it to write test code for your socket.io_ server.
|
||||
|
||||
Please note that this version implements `socket.io protocol 1.x <https://github.com/automattic/socket.io-protocol>`_, which is not backwards compatible. If you want to communicate using `socket.io protocol 0.9 <https://github.com/learnboost/socket.io-spec>`_ (which is compatible with `gevent-socketio <https://github.com/abourget/gevent-socketio>`_), please use `socketIO-client 0.5.6 <https://pypi.python.org/pypi/socketIO-client/0.5.6>`_.
|
||||
Thanks to rod_ for the `StackOverflow question and answer`__ on which this code is based.
|
||||
|
||||
Thanks to liris_ for websocket-client_ and to guille_ for the `socket.io specification`_.
|
||||
|
||||
Thanks to `Paul Kienzle`_, `Josh VanderLinden`_, `Ian Fitzpatrick`_ for submitting code to expand support of the socket.io protocol.
