celery模块

#在task文件中


from __future__ import absolute_import, unicode_literals
import os

from celery import Celery

# set the default Django settings module for the 'celery' program.
#        AXF.settings:项目下的settings文件
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'AXF.settings')


broker = 'redis://127.0.0.1:6379/6'  # 将要进行的任务
backend = 'redis://127.0.0.1:6379/7' # 返回的结果
app = Celery('App', broker=broker, backend=backend)
# app = Celery('App')

# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
#   should have a `CELERY_` prefix.
# app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()     #自动搜索所有的任务

'debug开启'
# @app.task(bind=True)
# def debug_task(self):
#     print('Request: {0!r}'.format(self.request))

App下的init文件

发送邮件

from celery import shared_task

@shared_task     #可多次重用,@shared_task装饰可以让你无需任何具体的应用程序实例创建任务
def send_register_mail(username, email, token):
    # 发送邮件
    print('------------------------------------')
    sleep(10)
    print('------------------------------------')
    title = '激活'
    msg = ' '

    data = {
        'username': username,
        'url': 'http://127.0.0.1:8000/app/active/?token=' + token
    }
    temp = loader.get_template('user/active.html')
    html = temp.render(data)

    receiver = [
        email,
    ]

    send_mail(title,
              msg,
              from_email=settings.DEFAULT_FROM_EMAIL,
              recipient_list=receiver,
              html_message=html)

    print('send mail')

发送邮件调用

send_register_mail.delay(username, email, token)

开启任务队列

celery -A task worker -l info        或者
celery -A task worker --loglevel=info
