配置

dj_01/dj_01/__init__.py

 import pymysql
 from .celery import app as celery_app

 pymysql.install_as_MySQLdb()
 __all__ = ['celery_app']

dj_01/dj_01/celery.py

 from __future__ import absolute_import, unicode_literals
 import os
 from celery import Celery
 from django.conf import settings
 # set the default Django settings module for the 'celery' program.
 os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'dj_01.settings')

 app = Celery('dj_01',backend='amqp', broker='amqp://guest:guest@localhost:5672//')
 app.config_from_object('django.conf:settings')
 app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

dj_01/dj_01/setting.py

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'mytest',

)

# Celery 设置
 # CELERY_BROKER_URL = 'redis://localhost:6379/0'
 BROKER_URL = 'amqp://guest:guest@127.0.0.1:5672//'
 CELERY_ACCEPT_CONTENT = ['json']
 CELERY_TASK_SERIALIZER = 'json'
 CELERY_RESULT_SERIALIZER = 'json'
 # CELERY_RESULT_BACKEND = 'django-db'

 from datetime import timedelta

 # 定时任务
 CELERYBEAT_SCHEDULE = {
     'add-every-30-seconds': {
         'task': 'mytest.tasks.add',  # 任务名
         'schedule': timedelta(seconds=2),  # 每2s执行一次该任务
         'args': (2, 3)
     }
 }

异步任务

服务：celery -A dj_01 worker -l info

app/tasks.py

 from time import sleep
 from celery import shared_task

 @shared_task  #celery -A dj_01 worker -l info
 def celeryTest(*ags,**kwargs):
     print('耗时操作任务start...')
     print(ags)
     print(kwargs)
     sleep(10)
     print('耗时操作任务end...')

app/view.py

from .tasks import celeryTest

1 def testt(req):
     d = {
         "result":'',
     }

     res = celeryTest.delay(json.dumps(d))
     print("res:%s"%res) #b9020fb2-61c1-494d-8e66-a86776943c76

     return render(req, 'acc_login.html')

定时任务

服务：celery -A dj_01 beat -l info
