Python的Websocket客戶端:Websocket-Client
Websocket-Client 是 Python 上的 Websocket 客戶端。它只支持 hybi-13,且所有的 Websocket API 都支持同步。
Installation
This module is tested on Python 2.7 and Python 3.x.
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 depend on
- six
- backports.ssl_match_hostname for Python 2.x
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:
import websocket
ws = websocket.WebSocket()
ws.connect("ws://example.com/websocket", http_proxy_host="proxy_host_name", http_proxy_port=3128)
: Example
Low Level API example:
from websocket import create_connection
ws = create_connection("ws://echo.websocket.org/")
print "Sending 'Hello, World'..."
ws.send("Hello, World")
print "Sent"
print "Reeiving..."
result = ws.recv()
print "Received '%s'" % result
ws.close() If you want to customize socket options, set sockopt.
sockopt example:
from websocket import create_connection
ws = create_connection("ws://echo.websocket.org/",
sockopt=((socket.IPPROTO_TCP, socket.TCP_NODELAY),)) JavaScript websocket-like API example:
import websocket
import 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()
