celery使用方法

1、celery4.0以上不支持windows，用pip安装celery

2、启动redis-server.exe服务

3、编辑运行celery_blog2.py

!/usr/bin/python

coding:utf-8

import requests

import time

from celery import Celery

app = Celery('celery_blog2', broker='redis://localhost:6379/1')

@app.task

def fetch_url(url):

resp = requests.get(url)

print 'mhj '+url

def func(urls):

start = time.time()

for url in urls:

fetch_url.delay(url)

print "It took ", time.time()-start, "seconds"

if name == 'main':

func(["http://oneapm.com", "http://jd.com", "https://taobao.com", "http://baidu.com", "http://news.oneapm.com"])

4、在celery_blog2.py目录运行一个worker，用来执行这个

celery -A celery_blog2 worker --loglevel=info
