flask_socketio 与 flask_script的融合

1. • 实现代码：

# -*- coding=utf8 -*-
from flask_migrate import MigrateCommand
from flask_script import Manager
from App import create_app
from flask_socketio import SocketIO

app = create_app()
manage = Manager(app=app)
manage.add_command('db', MigrateCommand)
# socketio = SocketIO()
socketio = SocketIO(logger=True, engineio_logger=True)  # 将日志输出到终端
socketio.init_app(app, cors_allowed_origins='*')    # 解决跨域问题


@manage.command
def run():
    socketio.run(app, host='0.0.0.0', port=5000)


# 主函数
if __name__ == '__main__':
    # app.debug = False
    # app.run()
    manage.run()

2. 关键代码

@manage.command
def run():
    socketio.run(app, host='0.0.0.0', port=5000)

控制台正常运行：
