|
Installation
|
||
|
|
============
|
||
|
|
|
||
|
|
This module is tested on Python 2.7 and Python 3.4+.
|
||
|
|
|
||
|
|
Type "python setup.py install" or "pip install websocket-client" to install.
|
||
|
|
|
||
|
|
.. CAUTION::
|
||
|
|
|
||
|
|
from v0.16.0, we can install by "pip install websocket-client" for Python 3.
|
||
|
|
|
||
|
|
This module depends on
|
||
|
|
|
||
|
|
- six
|
||
|
|
- backports.ssl_match_hostname for Python 2.x
|
||
|
|
|
||
|
|
Performance
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The "send" and "validate_utf8" methods are too slow on pure python. If you want to get better performace, please install both numpy and wsaccel.
|
||
|
|
|
||
|
|
|
||
|
|
How about Python 3
|
||
|
|
==================
|
||
|
|
|
||
|
|
Now, we support Python 3 on single source code from version 0.14.0. Thanks, @battlemidget and @ralphbean.
|
||
|
|
|
||
|
|
HTTP Proxy
|
||
|
|
==========
|
||
|
|
|
||
|
|
Support websocket access via http proxy.
|
||
|
|
The proxy server must allow "CONNECT" method to websocket port.
|
||
|
|
Default squid setting is "ALLOWED TO CONNECT ONLY HTTPS PORT".
|
||
|
|
|
||
|
|
Current implementation of websocket-client is using "CONNECT" method via proxy.
|
||
|
|
|
||
|
|
|
||
|
|
example
|
||
|
|
|
||
|
|
.. code:: python
|
||
|
|
|
||
|
|
import websocket
|
||
|
|
ws = websocket.WebSocket()
|
||
|
|
ws.connect("ws://example.com/websocket", http_proxy_host="proxy_host_name", http_proxy_port=3128)

|

|
|
Long-lived connection
|
||
|
|
---------------------
|
||
|
|
This example is similar to how WebSocket code looks in browsers using JavaScript.
|
||
|
|
|
||
|
|
.. code:: python
|
||
|
|
|
||
|
|
import websocket
|
||
|
|
try:
|
||
|
|
import thread
|
||
|
|
except ImportError:
|
||
|
|
import _thread as thread
|
||
|
|
import time
|
||
|
|
|
||
|
|
def on_message(ws, message):
|
||
|
|
print(message)
|
||
|
|
|
||
|
|
def on_error(ws, error):
|
||
|
|
print(error)
|
||
|
|
|
||
|
|
def on_close(ws):
|
||
|
|
print("### closed ###")
|
||
|
|
|
||
|
|
def on_open(ws):
|
||
|
|
def run(*args):
|
||
|
|
for i in range(3):
|
||
|
|
time.sleep(1)
|
||
|
|
ws.send("Hello %d" % i)
|
||
|
|
time.sleep(1)
|
||
|
|
ws.close()
|
||
|
|
print("thread terminating...")
|
||
|
|
thread.start_new_thread(run, ())
|
||
|
|
|
||
|
|
|
||
|
|
if __name__ == "__main__":
|
||
|
|
websocket.enableTrace(True)
|
||
|
|
ws = websocket.WebSocketApp("ws://echo.websocket.org/",
|
||
|
|
on_message = on_message,
|
||
|
|
on_error = on_error,
|
||
|
|
on_close = on_close)
|
||
|
|
ws.on_open = on_open
|
||
|
|
ws.run_forever()
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Short-lived one-off send-receive
|
||
|
|
--------------------------------
|
||
|
|
This is if you want to communicate a short message and disconnect immediately when done.
|
||
|
|
|
||
|
|
.. code:: python
|
||
|
|
|
||
|
|
from websocket import create_connection
|
||
|
|
ws = create_connection("ws://echo.websocket.org/")
|
||
|
|
print("Sending 'Hello, World'...")
|
||
|
|
ws.send("Hello, World")
|
||
|
|
print("Sent")
|
||
|
|
print("Receiving...")
|
||
|
|
result = ws.recv()
|
||
|
|
print("Received '%s'" % result)
|
||
|
|
ws.close()
|
||
|
|
|
||
|
|
|
||
|
|
If you want to customize socket options, set sockopt.
|
||
|
|
|
||
|
|
sockopt example
|
||
|
|
|
||
|
|
.. code:: python
|
||
|
|
|
||
|
|
from websocket import create_connection
|
||
|
|
ws = create_connection("ws://echo.websocket.org/",
|
||
|
|
sockopt=((socket.IPPROTO_TCP, socket.TCP_NODELAY),))
|
||
|
|
|
||
|
|
|
||
|
|
More advanced: Custom class
|
||
|
|
---------------------------
|
||
|
|
You can also write your own class for the connection, if you want to handle the nitty-gritty details yourself.
|
||
|
|
|
||
|
|
.. code:: python
|
||
|
|
|
||
|
|
import socket
|
||
|
|
from websocket import create_connection, WebSocket
|
||
|
|
class MyWebSocket(WebSocket):
|
||
|
|
def recv_frame(self):
|
||
|
|
frame = super().recv_frame()
|
||
|
|
print('yay! I got this frame: ', frame)
|
||
|
|
return frame
|
||
|
|
|
||
|
|
ws = create_connection("ws://echo.websocket.org/",
|
||
|
|
sockopt=((socket.IPPROTO_TCP, socket.TCP_NODELAY, 1),), class_=MyWebSocket)
