1. 安装

   pip install django==1.11.7
   pip install celery

3. settings配置

   #email
   EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
   EMAIL_USE_TLS = False
   EMAIL_USE_SSL = True
   EMAIL_HOST = 'smtp.163.com'
   EMAIL_PORT = 465
   EMAIL_HOST_USER = 'sajinde@163.com'
   EMAIL_HOST_PASSWORD = '**********'
   DEFAULT_FROM_EMAIL = 'sam <sajinde@163.com>'
   

4. 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))
   

5. App下的init文件

   from __future__ import absolute_import, unicode_literals
   from task import app as celery_app
   
   __all__ = ['celery_app']
   

6. 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')
   

7. 发送邮件调用

   send_register_mail.delay(username, email, token)
   

8. 开启任务队列

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