flask出现This is a development server. Do not use it in a production deployment. Falsk WSGI两种解决办法

WARNING: This is a development server. Do not use it in a production deployment. Falsk WSGI

“这个模式用于开发环境调试，部署线上需要使用WSGI替代”，这个提示的原因是flask需要使用WSGI启动服务，那就是用WSGI呗

两种方法：

方法一：

# pip install gevent 
from gevent import pywsgi

if __name__ == '__main__':
	server = pywsgi.WSGIServer(('0.0.0.0', 5000), app)
	server.serve_forever()

方法二：

from wsgiref.simple_server import make_server

if __name__ == '__main__':
	server = make_server('', 64570, app)
	server.serve_forever()
