socketIO-client 0.6.5

A socket.io client library

socketIO-client

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, which is not backwards compatible. If you want to communicate using socket.io protocol 0.9 (which is compatible with gevent-socketio), please use socketIO-client 0.5.6.

Installation

Install the package in an isolated environment.

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

Launch your socket.io server.

# Get package folder
PACKAGE_FOLDER=`python -c "import os, socketIO_client;\
    print(os.path.dirname(socketIO_client.__file__))"`
# Start socket.io server
DEBUG=* node $PACKAGE_FOLDER/tests/serve.js
# Start proxy server in a separate terminal on the same machine
DEBUG=* node $PACKAGE_FOLDER/tests/proxy.js

For debugging information, run these commands first.

import logging
logging.getLogger('requests').setLevel(logging.WARNING)
logging.basicConfig(level=logging.DEBUG)

Emit.

from socketIO_client import SocketIO, LoggingNamespace

with SocketIO('localhost', 8000, LoggingNamespace) as socketIO:
    socketIO.emit('aaa')
    socketIO.wait(seconds=1)

Emit with callback.

from socketIO_client import SocketIO, LoggingNamespace

def on_bbb_response(*args):
    print('on_bbb_response', args)

with SocketIO('localhost', 8000, LoggingNamespace) as socketIO:
    socketIO.emit('bbb', {'xxx': 'yyy'}, on_bbb_response)
    socketIO.wait_for_callbacks(seconds=1)

Define events.

from socketIO_client import SocketIO, LoggingNamespace

def on_aaa_response(*args):
    print('on_aaa_response', args)

socketIO = SocketIO('localhost', 8000, LoggingNamespace)
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', verify=False)

Specify params, headers, cookies, proxies thanks to the requests library.

from socketIO_client import SocketIO
from base64 import b64encode

SocketIO(
    localhost', 8000,
    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', 8000)
socketIO.wait()
