socketIO-client
|
|
===============
|
|
Here is a socket.io_ client library for Python. You can use it to write test code for your socket.io_ server.
|
|
|
|
Thanks to rod_ for the `StackOverflow question and answer`__ on which this code is based.
|
|
|
|
Thanks to `Hiroki Ohtani`_ for websocket-client_, `Guillermo Rauch`_ for the `socket.io specification`_ and `Alexandre Bourget`_ for gevent-socketio_.
|
|
|
|
Thanks to `Paul Kienzle`_, `Zac Lee`_, `Josh VanderLinden`_, `Ian Fitzpatrick`_, `Lucas Klein`_ for submitting code to expand support of the socket.io protocol.

|
|
|
|
VIRTUAL_ENV=$HOME/.virtualenv
|
|
|
|
# Prepare isolated environment
|
|
virtualenv $VIRTUAL_ENV
|
|
|
|
# Activate isolated environment
|
|

Usage
|
|
-----
|
|
Activate isolated environment. ::
|
|
|
|
VIRTUAL_ENV=$HOME/.virtualenv
|
|
source $VIRTUAL_ENV/bin/activate
|
|
|
|
Emit. ::
|
|
|
|
from socketIO_client import SocketIO
|
|
with SocketIO('localhost', 8000) as socketIO:
|
|
socketIO.emit('aaa')
|
|
socketIO.wait(1) # Wait a second
|
|
|
|
Emit with callback. ::
|
|
|
|
from socketIO_client import SocketIO
|
|
|
|
def on_response(*args):
|
|
print args
|
|
|
|
with SocketIO('localhost', 8000) as socketIO:
|
|
socketIO.emit('aaa', {'bbb': 'ccc'}, on_response)
|
|
socketIO.wait(seconds=1, forCallbacks=True) # Wait for callback
|
|
|
|
Define events. ::
|
|
|
|
from socketIO_client import SocketIO
|
|
|
|
def on_ddd(*args):
|
|
print args
|
|
|
|
socketIO = SocketIO('localhost', 8000)
|
|
socketIO.on('ddd', on_ddd)
|
|
socketIO.wait() # Loop until CTRL-C
|
|
|
|
Define events in a namespace. ::
|
|
|
|
from socketIO_client import SocketIO, BaseNamespace
|
|
|
|
class Namespace(BaseNamespace):
|
|
|
|
def on_ddd(self, *args):
|
|
self.emit('eee', {'fff': 'ggg'})
|
|
|
|
socketIO = SocketIO('localhost', 8000)
|
|
socketIO.define(Namespace)
|
|
socketIO.wait() # Loop until CTRL-C
|
|
|
|
Define standard events. ::
|
|
|
|
from socketIO_client import SocketIO, BaseNamespace
|
|
|
|
class Namespace(BaseNamespace):
|
|
|
|
def on_connect(self):
|
|
print '[Connected]'
|
|
|
|
def on_disconnect(self):
|
|
print '[Disconnected]'
|
|
|
|
def on_error(self, reason, advice):
|
|
print '[Error] %s' % advice
|
|
|
|
def on_message(self, messageData):
|
|
print '[Message] %s' % messageData
|
|
|
|
socketIO = SocketIO('localhost', 8000)
|
|
socketIO.define(Namespace)
|
|
socketIO.wait() # Loop until CTRL-C
|
|
|
|
Define different namespaces on a single socket. ::
|
|
|
|
from socketIO_client import SocketIO, BaseNamespace
|
|
|
|
class MainNamespace(BaseNamespace):
|
|
|
|
def on_aaa(self, *args):
|
|
print 'aaa', args
|
|
|
|
class ChatNamespace(BaseNamespace):
|
|
|
|
def on_bbb(self, *args):
|
|
print 'bbb', args
|
|
|
|
class NewsNamespace(BaseNamespace):
|
|
|
|
def on_ccc(self, *args):
|
|
print 'ccc', args
|
|
|
|
socketIO = SocketIO('localhost', 8000)
|
|
socketIO.define(MainNamespace)
|
|
chatNamespace = socketIO.define(ChatNamespace, '/chat')
|
|
chatNamespace.emit('bbb')
|
|
newsNamespace = socketIO.define(NewsNamespace, '/news')
|
|
newsNamespace.emit('ccc')
|
|
socketIO.wait() # Loop until CTRL-C
|
|
|
|
Open secure websockets (HTTPS / WSS) behind a proxy. ::
|
|
|
|
SocketIO('localhost', 8000,
|
|
secure=True,
|
|
proxies={'http': 'http://proxy.example.com:8080'})
