django + celery

首先安装必要的包:

pip install celery

pip install redis

project层:

setting.py

BROKER_URL = 'redis://127.0.0.1:6379/1'
CELERY_RESULT_BACKEND = 'redis://127.0.0.1:6379/3'
BROKER_TRANSPORT = 'redis'

celery.py

from __future__ import absolute_import  # 解决命名问题

import os
import django

from celery import Celery
from django.conf import settings

os.environ.setdefault('DJANGO_SETTINGS_MODULE', '项目名.settings')
# 设置配置文件
django.setup()

app = Celery('项目名')

app.config_from_object('django.conf:settings')  # 制定celery配置文件
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)  # 任务
# app.conf.result_backend = 'redis://localhost:6379/2'

__init__.py

from __future__ import absolute_import, unicode_literals

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

__all__ = ('celery_app',)

现在来到app:

tasks.py

from djcelery.celery import app

@app.task
def send():
    import time
    print('begin')
    time.sleep(5)
    print('end')
    return 25

views.py

from django.shortcuts import  HttpResponse
from .tasks import send

def test(request):
    send.delay()
    return HttpResponse('nihao')

开启任务:

 　　celery -A djcelery worker -l debug
