如何禁用flask app.run（）的默认消息？

Question

运行烧瓶应用程序时，例如

... 
if __name__ is "__main__":
    app.run(port=self.port)

...

有些消息正在运行。

* Serving Flask app "__main__" (lazy loading)
* Environment: production
  WARNING: Do not use the development server in a production environment.
  Use a production WSGI server instead.
* Debug mode: off
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

如何禁用所有这些消息？

Answer 1

要禁止Flask显示关于在生产环境中使用开发服务器的警告信息，请在运行flask之前添加以下2行：

from flask import Flask
import sys

cli = sys.modules['flask.cli']
cli.show_server_banner = lambda *x: None

app = Flask(__name__)
app.run(host='0.0.0.0', port='80')
