# websocket-client
websocket-client is a WebSocket client for Python. It provides access
to low level APIs for WebSockets. websocket-client implements version
[hybi-13](https://tools.ietf.org/html/draft-ietf-hybi-thewebsocketprotocol-13)
of the WebSocket protocol. This client does not currently support the
permessage-deflate extension from
[RFC 7692](https://tools.ietf.org/html/rfc7692).
## Documentation
This project's documentation can be found at
[https://websocket-client.readthedocs.io/](https://websocket-client.readthedocs.io/)
## Contributing
Please see the [contribution guidelines](https://github.com/websocket-client/websocket-client/blob/master/CONTRIBUTING.md)
## Installation
You can use either `python3 setup.py install` or `pip3 install websocket-client`
to install. This module is tested on Python 3.6+.
There are several optional dependencies that can be installed to enable
specific websocket-client features.
- To install `python-socks` for proxy usage and `wsaccel` for a minor performance boost, use:
`pip3 install websocket-client[optional]`
- To install `websockets` to run unit tests using the local echo server, use:
`pip3 install websocket-client[test]`
- To install `Sphinx` and `sphinx_rtd_theme` to build project documentation, use:
`pip3 install websocket-client[docs]`
Footnote: Some shells, such as zsh, require you to escape the `[` and `]` characters with a `\`.
## Usage Tips
Check out the documentation's FAQ for additional guidelines:
[https://websocket-client.readthedocs.io/en/latest/faq.html](https://websocket-client.readthedocs.io/en/latest/faq.html)
Known issues with this library include lack of WebSocket Compression
support (RFC 7692) and [minimal threading documentation/support](https://websocket-client.readthedocs.io/en/latest/threading.html).
## Performance
The `send` and `validate_utf8` methods can sometimes be bottleneck.
You can disable UTF8 validation in this library (and receive a
performance enhancement) with the `skip_utf8_validation` parameter.
If you want to get better performance, install wsaccel. While
websocket-client does not depend on wsaccel, it will be used if
available. wsaccel doubles the speed of UTF8 validation and
offers a very minor 10% performance boost when masking the
payload data as part of the `send` process. Numpy used to
be a suggested performance enhancement alternative, but
[issue #687](https://github.com/websocket-client/websocket-client/issues/687)
found it didn't help.
## Examples
Many more examples are found in the
[examples documentation](https://websocket-client.readthedocs.io/en/latest/examples.html).
### Long-lived Connection
Most real-world WebSockets situations involve longer-lived connections.
The WebSocketApp `run_forever` loop automatically tries to reconnect when a
connection is lost, and provides a variety of event-based connection controls.
```python
import websocket
import _thread
import time
def on_message(ws, message):
print(message)
def on_error(ws, error):
print(error)
def on_close(ws, close_status_code, close_msg):
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_open=on_open,
on_message=on_message,
on_error=on_error,
on_close=on_close)
ws.run_forever()
```
### Short-lived Connection
This is if you want to communicate a short message and disconnect
immediately when done. For example, if you want to confirm that a WebSocket
server is running and responds properly to a specific request.
```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, as seen below:
```python
from websocket import create_connection
ws = create_connection("ws://echo.websocket.org/",
sockopt=((socket.IPPROTO_TCP, socket.TCP_NODELAY),))
```
