Flask-SocketIO

[mal2tin]

First of all Thanks for the library. I have a small program that works very well with websocket and aiohttp. For implementation reasons, they ask me to use a single port. I found "Flask-SocketIO", but I feel at a loss on how to make it work ... Did anyone? any ideas?

Hello. Glad to hear that the library useful for you.

I just created a PR #181 that explains how to write websocket adapters. Does that help you?

Not really. It's my first time in python and it's really hard for me ... I'm trying to do something like that but I can't ... Thanks for your time.

Can you fix the indenting of the code? And can you elaborate on why this code doesn't work?

[mal2tin]

It tells me that the websocket does not have the recv property. I understand that I do not import the websockets library but I use the one from fastapi ... the truth is that I do not know how to do it so that it works together. I only manage to connect, but I can't do the .start (). It really worked very well for me if I used fastapi ... :( Thank you for your time, you are incredible and I am immensely grateful. I attach a program to avoid indentation problems. El mié, 3 mar 2021 a las 5:02, Auke Willem Oosterhoff (< notifications@github.com>) escribió:

FAST API is not support for "wss"(secure), it is only for ws.
