How to add a web server to an existing long-running Python program?
问题
我有一个长时间运行的Python程序，定期执行工作。我需要它还能够托管一个Web服务器，以便提供指标和其他管理功能。我想使用Flask作为Web框架，虽然这不是硬性要求 - 我只需要路由一些URL。有适合在后台线程上托管的Web服务器吗？
我想要的解决方案类似于Golang的net/http Web服务器，其中我可以在其自己的goroutine上托管并启动/停止它。
我已经使用Flask内置的开发服务器使其工作，但其文档建议不要在生产中使用。同样，适用于Python的http.server。
编辑：我还尝试在后台线程上使用Gunicorn的BaseApplication，但在幕后，它监听操作系统信号，这在除了主Python解释器线程以外是不允许的。对于twisted也是如此。
英文:
I have a long-running Python program that is periodically performing work. I have a requirement for it to also host a web server so that it can serve metrics and other admin capabilities. I'd like to use Flask as the web framework, although this isn't a deal-breaker - I only need to route a few URLs. Is there a suitable web server that I can host on a background thread?
I suppose the solution I'm looking for is akin to Golang's net/http web server wherein I can host and start/stop it on its own goroutine.
I have got this working using Flask's inbuilt development server but its documentation advises that this should not be used in production. Likewise for Python's http.server.
Edit: I have also tried using Gunicorn's BaseApplication on a background thread but, under-the-hood, it listens for OS signals which isn't allowed on anything but the main Python interpreter thread. Ditto for twisted.

Flask不适合生产环境，因为它不具备良好的扩展性...但是你可以使用像Bottle这样的框架。
英文:
Flask is not suitable for production because it doesn't scale well...
however you can use a framework like Bottle.
