socketIO async_mode=eventlet unable to display some logs

[liuqijie6]

socketIO config

socket_io = SocketIO(cors_allowed_origins='*',
                     async_mode="threading",  # eventlet  gevent # threading
                     # engineio_logger=True,
                     # logger=True,
                     message_queue=f'redis://:{password}@{host}:{port}/0',
                     )

app.py

__all__ = ["app"]
import eventlet
eventlet.monkey_patch()
from __init__ import create_app
from units.extensions import socket_io
from config import CONFIG

app = create_app()

if __name__ == "__main__":
    host, port = CONFIG.get("web_server", "host"), CONFIG.get("web_server", "port")
    # print(app.url_map)
    # app.run(host=host, port=port, threaded=False, debug=False)
    socket_io.run(app, host=host, port=port, debug=False)

if async_mode = eventlet , cant print this.
if async_mode = threading , can print this.

I think this is a misunderstanding on your part. When you use threading, you are using the Flask development web server. If you change the async mode to eventlet you are using eventlet's web server. The choice to log or not to log depends on each web server. The eventlet server uses the log_output option in the socket_io.run() function to determine if logging is enabled or not.
