title: Python - Broadcasting with WebSocket using AutobahnPython
body: <p>I have read this example from AutobahnPython: <code>https://github.com/tavendo/AutobahnPython/tree/master/examples/websocket/broadcast</code></p>
  
  <p>It looks pretty easy to understand and practice. But I want to add a little more. Members who submit the correct secret string can send the messages, anyone else can only view the information transmitted. Any idea?</p>
  
  <p>Thanks!</p>
