异步任务----Django-celery

推荐版本：

Django2.2.6
django-celery3.3.1
Django=redis4.11.0
redis2.10.6
celery==3.1.26post2

settings.py：

import djcelery

djcelery.setup_loader()
BROKER_URL = 'redis://127.0.0.1:6379/2'

INSTALLED_APPS = [
"djcelery",
]

创建celery需要的数据表

python manage.py migrate
如果失败的话可以试试
#python manage.py syncdb

然后在Django的APP下面在创建tasks.py

tasks.py：

from celery import task

from celery import task
import time

@task
def add(x, y):
result = x + y
time.sleep(5) # 可有可无，睡眠五秒
# print(f'{add.name}结果为：', result)
return result

Views.py：

from rest_framework.views import APIView
from rest_framework.response import Response
from app01.tasks import add

class TestCeleryView(APIView):
def get(self, request):

add.delay(5, 10) # delay是注册为celery异步任务的关键点

return Response({"code": 200})

启动celery：

python manage.py celery worker --loglevel=infov

如果报错不让超级管理员来启动，在settings.py加入以下配置
from celery import Celery, platforms
platforms.C_FORCE_ROOT = True
