python - 服务器在终端中运行，但未显示在页面中。 服务Flask应用“应用”（延迟加载）(Server runs in terminal but doesn't appear in the page. Serving Flask app “application” (lazy loading))

Question

• Serving Flask app "application" (lazy loading)

  (服务Flask应用“应用”（延迟加载）)

• Environment: production WARNING: Do not use the development server in a production environment.

  (环境：生产中警告：请勿在生产环境中使用开发服务器。)

  Use a production WSGI server instead.

  (请改用生产WSGI服务器。)

• Debug mode: off

  (调试模式：关闭)

  @application.route('/', methods=['POST', 'GET']) @application.route('/') def default():

  (@ application.route（'/'，methods = ['POST'，'GET']）@ application.route（'/'）def default（）：)

Originally, running python application.py works - the page appears but after a while of doing the same thing, the web page doesn't appear anymore and instead the warning above shows in my terminal.

(最初，运行python application.py可以正常工作-该页面出现，但经过一阵子相同的操作后，该网页不再显示，而是在我的终端中显示了以上警告。)

What is the problem?

" While lightweight and easy to use, Flask's built-in server is not suitable for production as it doesn't scale well and by default serves only one request at a time. "

(“虽然轻巧易用，但Flask的内置服务器不能很好地进行生产，因为它不能很好地扩展，并且默认情况下一次只能满足一个请求。”)

I also found this: warning message while running flask

(我也发现了这一点： 运行烧瓶时出现警告消息)

If you search with the warning/error message you get, you will find questions that were already answered.
