|
|
===============
|
|
Here is a socket.io_ client library for Python. You can use it to write test code for your socket.io_ server.
|
|
|
|
|
|
Installation
|
|
------------
|
|
::
|
|
|
|
VIRTUAL_ENV=$HOME/.virtualenv
|
|
|
|
# Prepare isolated environment
|
|
virtualenv $VIRTUAL_ENV
|
|
|
|
# Activate isolated environment
|
|
source $VIRTUAL_ENV/bin/activate
|
|
|
|
# Install package
|
|
pip install -U socketIO-client
|
|
|
|
|
|
Usage
|
|
-----
|
|
Activate isolated environment. ::
|
|
|
|
VIRTUAL_ENV=$HOME/.virtualenv
|
|
source $VIRTUAL_ENV/bin/activate
|
|
|
|
For debugging information, run these commands first. ::
|
|
|
|
import logging
|
|
logging.basicConfig(level=logging.DEBUG)
|
|
|
|
Emit. ::
|
|
|
|
from socketIO_client import SocketIO
|
|
|
|
with SocketIO('localhost', 8000) as socketIO:
|
|
socketIO.emit('aaa')
|
|
socketIO.wait(seconds=1)
|
|
|
|
Emit with callback. ::
|
|
|
|
from socketIO_client import SocketIO
|
|
|
|
def on_bbb_response(*args):
|
|
print 'on_bbb_response', args
|
|
|
|
with SocketIO('localhost', 8000) as socketIO:
|
|
socketIO.emit('bbb', {'xxx': 'yyy'}, on_bbb_response)
|
|
socketIO.wait_for_callbacks(seconds=1)
|
|
|
|
Define events. ::
|
|
|
|
from socketIO_client import SocketIO
|
|
|
|
def on_aaa_response(*args):
|
|
print 'on_aaa_response', args
|
|
|
|
socketIO = SocketIO('localhost', 8000)
|
|
socketIO.on('aaa_response', on_aaa_response)
|
|
socketIO.emit('aaa')
|
|
socketIO.wait(seconds=1)
|
|
|
|
Define events in a namespace. ::
|
|
|
|
from socketIO_client import SocketIO, BaseNamespace
|
|
|
|
class Namespace(BaseNamespace):
|
|
|
|
def on_aaa_response(self, *args):
|
|
print 'on_aaa_response', args
|
|
self.emit('bbb')
|
|
|
|
socketIO = SocketIO('localhost', 8000, Namespace)
|
|
socketIO.emit('aaa')
|
|
socketIO.wait(seconds=1)
|
|
|
|
Define standard events. ::
|
|
|
|
from socketIO_client import SocketIO, BaseNamespace
|
|
|
|
class Namespace(BaseNamespace):
|
|
|
|
def on_connect(self):
|
|
print '[Connected]'
|
|
|
|
socketIO = SocketIO('localhost', 8000, Namespace)
|
|
socketIO.wait(seconds=1)
|
|
|
|
Define different namespaces on a single socket. ::
|
|
|
|
from socketIO_client import SocketIO, BaseNamespace
|
|
|
|
class ChatNamespace(BaseNamespace):
|
|
|
|
def on_aaa_response(self, *args):
|
|
print 'on_aaa_response', args
|
|
|
|
class NewsNamespace(BaseNamespace):
|
|
|
|
def on_aaa_response(self, *args):
|
|
print 'on_aaa_response', args
|
|
|
|
socketIO = SocketIO('localhost', 8000)
|
|
chat_namespace = socketIO.define(ChatNamespace, '/chat')
|
|
news_namespace = socketIO.define(NewsNamespace, '/news')
|
|
|
|
chat_namespace.emit('aaa')
|
|
news_namespace.emit('aaa')
|
|
socketIO.wait(seconds=1)
|
|
|
|
Connect via SSL. ::
|
|
|
|
from socketIO_client import SocketIO
|
|
|
|
SocketIO('https://localhost')
|
|
|
|
Specify params, headers, cookies, proxies thanks to the `requests`_ library. ::
|
|
|
|
from socketIO_client import SocketIO
|
|
from base64 import b64encode
|
|
|
|
SocketIO('localhost', 8000,
|
|
resource='my.io',
|
|
params={'q': 'qqq'},
|
|
headers={'Authorization': 'Basic ' + b64encode('username:password')},
|
|
cookies={'a': 'aaa'},
|
|
proxies={'https': 'https://proxy.example.com:8080'})
|
|
|
|
Wait forever. ::
|
|
|
|
from socketIO_client import SocketIO
|
|
|
|
socketIO = SocketIO('localhost')
|
|
socketIO.wait()
