Basics
2+
============
3+
4+
ws4py provides high-level, yet simple, interface to provide your application with WebSocket support.
5+
6+
.. code-block:: python
7+
8+
from ws4py.websocket import WebSocket
9+
10+
The :class:`WebSocket <ws4py.websocket.WebSocket>` should be sub-classes by your application to make something sensible with it. To the very least we suggest you override the :func:`received_message(message) <ws4py.websocket.WebSocket.received_message>` method.
11+
12+
For instance a straightforward echo application would look like this:
13+
14+
.. code-block:: python
15+
16+
class EchoWebSocket(WebSocket):
17+
def received_message(self, message):
18+
self.send(message.data, message.is_binary)
19+
20+
Other useful methods to implement are:
21+
22+
* :func:`opened() <ws4py.websocket.WebSocket.opened>` which is called whenever the WebSocket handshake is done.
23+
* :func:`closed(code, reason=None) <ws4py.websocket.WebSocket.closed>` which is called whenever the WebSocket connection is terminated.
24+
25+
You may want to know if the connection is currently usable or :attr:`terminated <ws4py.websocket.WebSocket.terminated>`.

Client
2+
======
3+
4+
Built-in
5+
--------
6+
7+
ws4py comes with various client implementation but they roughly share the same aspects when your application needs one.
8+
9+
An example is better than any word so let's have a look at a basic client:
10+
11+
.. code-block:: python
12+
13+
from ws4py.client.threadedclient import WebSocketClient
14+
15+
class DummyClient(WebSocketClient):
16+
def opened(self):
17+
def data_provider():
18+
for i in range(1, 200, 25):
19+
yield "#" * i
20+
21+
self.send(data_provider())
22+
23+
for i in range(0, 200, 25):
24+
print i
25+
self.send("*" * i)
26+
27+
def closed(self, code, reason):
28+
print "Closed down", code, reason
29+
30+
def received_message(self, m):
31+
print "=> %d %s" % (len(m), str(m))
32+
if len(str(m)) == 175:
33+
self.close(reason='Bye bye')
34+
35+
if __name__ == '__main__':
36+
try:
37+
ws = DummyClient('ws://localhost:9000/', protocols=['http-only', 'chat'])
38+
ws.connect()
39+
except KeyboardInterrupt:
40+
ws.close()
41+
42+
This example demonstrates how to implement a client, here based on a thread-model, that is able to send and receive messages from a connected endpoint at ws://localhost:9000/.
43+
44+
In this snippet, when the handshake is successful, the :func:`opened() <ws4py.websocket.WebSocket.opened>` method is called and within this method we immediatly send to the server a bunch of messages. First we demonstrate how you can use a generator to do so, then we simply send strings.
45+
46+
Assuming the server echoes messages as they arrive, the :func:`received_message(message) <ws4py.websocket.WebSocket.received_message>` method will print out the messages returned by the server and simply closes the connection once it receives the last sent messages , which length is 175.
47+
48+
Finally the :func:`closed(code, reason=None) <ws4py.websocket.WebSocket.closed>` method is called with the code and reason given by the server.
49+
50+
Tornado
51+
-------
52+
53+
If you are using a Tornado backend you may use the Tornado client that ws4py provides as follow:
54+
55+
56+
.. code-block:: python
57+
58+
from ws4py.client.tornadoclient import WebSocketClient
59+
60+
The previous example runs exactly in the same way.
61+
62+
63+
gevent
64+
------
65+
66+
If you are using a gevent backend you may use the gevent client that ws4py provides as follow:
67+
68+
69+
.. code-block:: python
70+
71+
from ws4py.client.geventclient import WebSocketClient
72+
73+
The previous example runs exactly in the same way.
