# 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 procotol. 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

First, install the following dependencies:
- six
- backports.ssl\_match\_hostname for Python 2.x

You can install the dependencies with the command `pip install six` and
`pip install backports.ssl_match_hostname`

You can use either `python setup.py install` or `pip install websocket-client`
to install. This module is tested on Python 2.7 and Python 3.4+. Python 3
support was first introduced in version 0.14.0, but is a work in progress.

## 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).

## License

- LGPL version 2.1

### Performance

The `send` and `validate_utf8` methods are very slow in pure Python. 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, please install both numpy and wsaccel, and import them into your
project files - these other libraries will automatically be used when available.
Note that wsaccel can sometimes cause other issues.

### 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.
The project documentation has
[additional examples](https://websocket-client.readthedocs.io/en/latest/examples.html)

```python
import websocket
try:
    import thread
except ImportError:
    import _thread as 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_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.
The project documentation has
[additional examples](https://websocket-client.readthedocs.io/en/latest/examples.html)

```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),))
```
