Python猎鹰和异步操作 [英] Python falcon and async operations

问题描述

我正在使用python3 + falcon组合编写API.

I am writing an API using python3 + falcon combination.

方法中有很多地方可以向客户端发送回复，但是由于执行DB，I/O操作等繁琐的代码，它不得不等到繁重的部分结束.

There are lot of places in methods where I can send a reply to a client but because of some heavy code which does DB, i/o operations, etc it has to wait until the heavy part ends.

例如:

class APIHandler:                                                                      
  def on_get(self, req, resp):
    response = "Hello"
    #Some heavy code
    resp.body(response)

我可以在代码的第一行发送"Hello".我想要的是在后台运行沉重的代码并发送响应，而不管沉重的时间何时结束.

I could send "Hello" at the first line of code. What I want is to run the heavy code in a background and send a response regardless of when the heavy part finishes.

Falcon没有任何内置的异步功能，但是他们提到它可以与gevent之类的东西一起使用.我还没有找到有关如何将两者结合的文档.

Falcon does not have any built-in async capabilities but they mention it can be used with something like gevent. I haven't found any documentation of how to combine those two.

推荐答案

我将Celery用于异步相关的作品.我不知道gevent.请看一下 http://celery.readthedocs.org/en/latest/getting-started/introduction.html

I use Celery for async related works . I don't know about gevent .Take a look at this http://celery.readthedocs.org/en/latest/getting-started/introduction.html
