Getting Started

The quickest way to get started with this library is to use the _wsdump.py script. For an easy example, run the following:

python _wsdump.py ws://echo.websocket.events/ -t "hello world"

The above command will provide you with an interactive terminal to communicate with the echo.websocket.events server. This server will echo back any message you send it. You can test this WebSocket connection in your browser, without this library, by visiting the URL https://websocket.org/echo.html.

The wsdump.py script has many additional options too, so it’s a great way to try using this library without writing any custom code. The output of python wsdump.py -h is seen below, showing the additional options available.

python wsdump.py -h
usage: wsdump.py [-h] [-p PROXY] [-v [VERBOSE]] [-n] [-r]
                 [-s [SUBPROTOCOLS [SUBPROTOCOLS ...]]] [-o ORIGIN]
                 [--eof-wait EOF_WAIT] [-t TEXT] [--timings]
                 [--headers HEADERS]
                 ws_url
