[blstdmi]

1 Client Get html+js
2 socketio connect url
window.socket = io.connect('http://IP:5000?psid=12f3aa43fdc7446881a0386c850ad8b8');
3 psid = hash unique pass in databasess and it session id

    def _handle_connect(self, environ, start_response, transport, b64=False):
        """Handle a client connection request."""
        query = urllib.parse.parse_qs(environ.get('QUERY_STRING', ''))
        if 'psid' in query:
            sid = query['psid'][0]
        else:
            sid = uuid.uuid4().hex
        #sid = self._generate_id()

how can send password to socketio in step 1 get html , maybe flask session cookie (socketio session cookie?)?
or
whan socketio connected send in io , password? give example

maybe example send hash password

You can use request.args['psid'] to get your password hash in the connect handler:

@socketio.on('connect')
def on_connect():
    psid = request.args['psid']
    # do what you need to do to authorize user
    # return False if password is not valid

thx, i now, I understand that I was not able to form question;
probably one of the bad login attempts;
Now I look and see what to do on the server side after already spent connect event, maybe
facundoolano/socketio-auth
better-authentication-for-socket-io-no-query-strings

Sure, those are valid options. You can also do the authentication over HTTP and save the result on the session variable, which you can access from any Socket.IO handlers.
