How to use custom id as session id in Flask Socket IO












0















I am using flask socket-io for a basic chat app. But I have a problem. When my device connect to server, flask give to device a session id. But after disconnect and again connect, session id changes. So, this device can't receive old room's messages. I thought if I'd do if I assign custom session id to device.Is it true? Or what is your suggestions?

          What you need to do is map a session id to your user information in the connect event, and remove the mapping in the disconnect event. That way at any time you can find out what session id a user is currently on. If you need specific room assignments, those need to be done upon connection, and undone on disconnection.

          The session ids are supposed to be unique, even when a client reconnects. There is no way for an application to choose these ids, they are random numbers chosen by the server.



          What you need to do is map a session id to your user information in the connect event, and remove the mapping in the disconnect event. That way at any time you can find out what session id a user is currently on. If you need specific room assignments, those need to be done upon connection, and undone on disconnection.
