【Flask】WARNING: This is a development server. Do not use it in a production deployment.

在用flask进行开发的时候，突然看到有如下警告

* Serving Flask app "5star" (lazy loading)
* Environment: production
  WARNING: This is a development server. Do not use it in a production deployment.
  Use a production WSGI server instead.
* Debug mode: on

解决问题的关键就在于

Use a production WSGI server instead.

很快搜到了解决方案：

if __name__ == '__main__':
    server = make_server('127.0.0.1', 5000, app)
    server.serve_forever()
    app.run()
