关于celery的一个小demo

1. demo的目录结构（请自行忽略test.py文件 => 无效）
   

task.py(实例化celery)
#! /usr/bin/env python
# encoding: utf-8

import time
from celery import Celery

app = Celery('tasks', broker='redis://localhost:6379/0', backend='redis://localhost:6379/1')


@app.task
def send_mail(email):
    print('send email to:', email)
    time.sleep(6)
    return 'send email success'

user.py（应用celery中定义的任务）
#! /usr/bin/env python
# encoding: utf-8

import time
from tasks import send_mail


def register():
    start = time.time()
    print('1. 插入记录到数据库')
    print('2. celery 帮我发邮件')
    send_mail.delay('[email protected]')
    print('3. 告诉用户注册成功')
    print('总耗时：%s秒' % (time.time() - start))


if __name__ == '__main__':
    register()
