# 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 `pip install websocket-client` to install, or `pip install -e .`
|
||||
to install from a local copy of the code. This module is tested on Python 3.8+.
|
||||
|
||||
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:
|
||||
`pip install websocket-client[optional]`
|
||||
- To install `websockets` to run unit tests using the local echo server, use:
|
||||
`pip install websocket-client[test]`
|
||||
- To install `Sphinx` and `sphinx_rtd_theme` to build project documentation, use:
|
||||
`pip 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 `pip 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()
|
||||
```
