Authentication for the WS endpoint

[jordan-dimov]

Hi,

Does anyone have an example of implementing authentication and / or some form of access control to the Perspective web socket endpoint in a FastAPI app. Particularly when using the PerspectiveStarletteHandler like this:

    async def websocket_handler(websocket: WebSocket):
        handler = PerspectiveStarletteHandler(
            perspective_server=perspective_server, websocket=websocket
        )
        await handler.run()

    app.add_api_websocket_route("/data", websocket_handler)

The use case is that certain users should only be able to access a filtered subset of the data in a table.
