python websocket-client connection
参考:https://pypi.python.org/pypi/websocket-client/ https://www.cnblogs.com/saryli/p/6702260.html
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()
Short-lived one-off send-receive
This is if you want to communicate a short message and disconnect immediately when done.
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
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.
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),), class_=MyWebSocket)
