( flask )如何检测flask插座中的客户端断开连接

pip install flask-socketio

from flask import Flask, render_template
from flask_socketio import SocketIO, disconnect

app = Flask(__name__)
app.config['SECRET_KEY'] = 'your_secret_key'
socketio = SocketIO(app)

@socketio.on('connect')
def handle_connect():
    print('Client connected')

@socketio.on('message')
def handle_message(message):
    print('Received message: ' + message)

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

if __name__ == '__main__':
    socketio.run(app)
