Django celery异步任务实现代码示例

from __future__ import absolute_import

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celerypro import app as celery_app

from __future__ import absolute_import
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', 'voice_quality_assurance_configure.settings') #修改项目配置文件的地址
app = Celery('voice_quality_assurance_configure') #修改项目目录名称
# Using a string here means the worker will not have to
# pickle the object when using Windows.
app.config_from_object('voice_quality_assurance_configure.celeryconfig') #修改celery配置文件的地址
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)
