Solve the following python programming problem given the following code:
def GET(self, token = None, **kwargs) : 
    '
        Return a websocket connection of Salt\'s event stream

        .. http:get:: /ws/(token)

        :query format_events: The event stream will undergo server-side
            formatting if the ``format_events`` URL parameter is included
            in the request. This can be useful to avoid formatting on the
            client-side:

            .. code-block:: bash

                curl -NsS <...snip...> localhost:8000/ws?format_events

        :reqheader X-Auth-Token: an authentication token from
            :py:class:`~Login`.

        :status 101: switching to the websockets protocol
        :status 401: |401|
        :status 406: |406|

        **Example request:** ::

            curl -NsSk \\
                -H \'X-Auth-Token: ffedf49d\' \\
                -H \'Host: localhost:8000\' \\
                -H \'Connection: Upgrade\' \\
                -H \'Upgrade: websocket\' \\
                -H \'Origin: https://localhost:8000\' \\
                -H \'Sec-WebSocket-Version: 13\' \\
                -H \'Sec-WebSocket-Key: \'"$(echo -n $RANDOM | base64)" \\
                localhost:8000/ws

        .. code-block:: http

            GET /ws HTTP/1.1
            Connection: Upgrade
            Upgrade: websocket
            Host: localhost:8000
            Origin: https://localhost:8000
            Sec-WebSocket-Version: 13
            Sec-WebSocket-Key: s65VsgHigh7v/Jcf4nXHnA==
            X-Auth-Token: ffedf49d

        **Example response**:

        .. code-block:: http

            HTTP/1.1 101 Switching Protocols
            Upgrade: websocket
            Connection: Upgrade
            Sec-WebSocket-Accept: mWZjBV9FCglzn1rIKJAxrTFlnJE=
            Sec-WebSocket-Version: 13

        An authentication token **may optionally** be passed as part of the URL
        for browsers that cannot be configured to send the authentication
        header or cookie:

        .. code-block:: bash

            curl -NsS <...snip...> localhost:8000/ws/ffedf49d

...
