How to use g in generator?

[DAAworld]

app = current_app._get_current_object()
return Response(generate_res(app, g.token), content_type='text/event-stream')

I use a generator to implement streaming responses. But I found that I can't use g in the generator, and it says it's out of context.

You're looking for the stream_with_context function/decorator, documented here: https://flask.palletsprojects.com/page/patterns/streaming/#streaming-with-context
