connection status problem

[DC-Lin]

Please help, how can I know that the user closed the connection and then I stop sending content to the user

[DC-Lin]

For example, I keep sending messages to the user, but the user closed the connection, I have to stop sending messages to the user, what should I do to know the user closed the connection status

Please do not write issues when you have questions. Use the discussion board instead.

When the user disconnects you receive the disconnect event.

Thank you very much！

Now, defining the disconnect event does not solve a problem. If disconnect is an event route, how does another route get the result returned by disconnect。
example:
@socketio.on('my_event')
def test_connect(auth):
whilt not disconnect: #if user don't closed this connection,but how can i get dicconnection flag here.
emit('my response', {'data': 'Connected'})

@socketio.on('disconnect')
def test_disconnect():
print('Client disconnected')

This package does not support a serial way of writing your logic, you have to structure your application with events. You shouldn't have a while loop in the connect handler, that is an event in which you have to allow or reject clients, it should return quickly. I suggest you look at the examples in this repository to learn about creating events.

For example, you can set a global variable or event object in your disconnect handler, so that another function that is serving the client know when to stop.
