龙卷风烧瓶关闭等待 [英] tornado flask close wait

问题描述

当我使Web应用程序使用 torado + flask 时，我遇到一个问题，当我向应用程序发送请求时，它对我什么都没有响应，并且始终等待着.当我发现问题时，我发现我的服务器计算机(linux)中有许多关闭等待" .我不知道如何解决这个问题，有人可以帮我吗?这是我使用龙卷风的代码:

when i make a web application use torado+flask ,i meet a question that when i send a request to my application,it response nothing to me ,and its always await. when i find the problem,i found that there is many 'close wait' in my server machine(linux). i don't know how to resolve this question,can anybody help me? here is the code i use tornado:

#coding=utf-8
from tornado.wsgi import WSGIContainer
from tornado.httpserver import HTTPServer`enter code here`
from tornado.ioloop import IOLoop
from service import app #app is a flask in another file:app=Flask(__name__)
from config import SERVER_CONF
from appLog import logging


def startService():
    logging.info('start web,http://%s:%s/test'%(SERVER_CONF['IP'],SERVER_CONF['PORT']))
    try:
        http_server=HTTPServer(WSGIContainer(app))
        http_server.listen(SERVER_CONF['PORT'],address=SERVER_CONF['IP'])
        IOLoop.instance().start()
    except Exception as e:
        logging.error('start failed:')
        logging.error(e)


if __name__=='__main__':
    startService()

推荐答案

我的理解是，您需要使用 FallbackHandler ，如

My understanding is that you need to use FallbackHandler, as described in this answer.

话虽如此，我强烈建议您不要使用这种方法-Tornado包含出色的自己的微框架，它与服务器的集成度更高，并且在许多方面都优于Flask.如果使用Flask很重要，我建议您探索一种不同的方式来确保并发性(例如，在nginx负载均衡器后面的多个实例)，或者甚至看看 Sanic ，它既异步又与Flask非常相似.

That being said, I would strongly recommend against using this approach -- Tornado includes an excellent microframework of its own, which integrates much better with the server and is in many ways superior to Flask. If using Flask is important I would recommend exploring a different ways to ensure concurrency (e.g. multiple instances behind a nginx load balancer), or even taking a look at Sanic, which is both asynchronous and very similar to Flask.
