- # 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 3.7+.
-
- 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]`
-
- While not a strict dependency, [rel](https://github.com/bubbleboy14/registeredeventlistener)
- is useful when using `run_forever` with automatic reconnect. Install rel with `pip3 install rel`.
-
- 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 will automatically try to reconnect
- to an open WebSocket connection when a network
- connection is lost if it is provided with:
-
- - a `dispatcher` argument (async dispatcher like rel or pyevent)
- - a non-zero `reconnect` argument (delay between disconnection and attempted reconnection)
-
- `run_forever` provides a variety of event-based connection controls
- using callbacks like `on_message` and `on_error`.
- `run_forever` **does not automatically reconnect** if the server
- closes the WebSocket gracefully (returning
- [a standard websocket close code](https://www.rfc-editor.org/rfc/rfc6455.html#section-7.4.1)).
- [This is the logic](https://github.com/websocket-client/websocket-client/pull/838#issuecomment-1228454826) behind the decision.
- Customizing behavior when the server closes
- the WebSocket should be handled in the `on_close` callback.
- This example uses [rel](https://github.com/bubbleboy14/registeredeventlistener)
- for the dispatcher to provide automatic reconnection.
-
- ```python
- import websocket
- import _thread
- import time
- import rel
-
- 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):
- print("Opened connection")
-
- if __name__ == "__main__":
- websocket.enableTrace(True)
- ws = websocket.WebSocketApp("wss://api.gemini.com/v1/marketdata/BTCUSD",
- on_open=on_open,
- on_message=on_message,
- on_error=on_error,
- on_close=on_close)
-
- ws.run_forever(dispatcher=rel, reconnect=5) # Set dispatcher to automatic reconnection, 5 second reconnect delay if connection closed unexpectedly
- rel.signal(2, rel.abort) # Keyboard Interrupt
- rel.dispatch()
- ```
-
- ### 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.events/")
- print(ws.recv())
- print("Sending 'Hello, World'...")
- ws.send("Hello, World")
- print("Sent")
- print("Receiving...")
- result = ws.recv()
- print("Received '%s'" % result)
- ws.close()
- ```
