1.celery设置
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'steam_user', # steam
'djcelery', # celery 注册到应用中
'rest_framework',
]
REDIS_HOST = '10.133.3.26'
REDIS_POST = 6379
REDIS_DATABASE = 3
REDIS_PASSWORD = ''
import djcelery
djcelery.setup_loader()
# celery中间人 redis://redis服务所在的ip地址:端口/数据库号
BROKER_URL = 'redis://:{}@{}:{}/{}'.format(REDIS_PASSWORD, REDIS_HOST, REDIS_POST, REDIS_DATABASE)
# celery结果返回，可用于跟踪结果
CELERY_RESULT_BACKEND = 'redis://:{}@{}:{}/{}'.format(REDIS_PASSWORD, REDIS_HOST, REDIS_POST, REDIS_DATABASE)
CELERY_IMPORTS = ('apps.steam_user.tasks') # tasks 路径
CELERY_BROKER_URL = 'redis://:{}@{}:{}/{}'.format(REDIS_PASSWORD, REDIS_HOST, REDIS_POST, REDIS_DATABASE)
# celery内容等消息的格式设置
CELERY_ACCEPT_CONTENT = ['application/json', ]
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
# celery时区设置，使用settings中TIME_ZONE同样的时区
CELERY_TIMEZONE = 'Asia/Shanghai'
2.在项目目录下创建celery.py文件 与setting.py同级目录
from __future__ import absolute_import, unicode_literals
from celery import Celery
from django.conf import settings
from os import path, environ
project_name = path.split(path.dirname(__file__))[-1] # okr_manage
project_settings = "{}.settings".format(project_name)
# 设置环境变量
environ.setdefault("DJANGO_SETTINGS_MODULE", project_settings)
# 实例化Celery
app = Celery(project_name)
# 使用django的settings文件配置celery
app.config_from_object("django.conf:settings")
# Celery加载所有注册的应用
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)
@app.task(bind=True)
def debug_task(self):
print("Request: {0!r}".format(self.request))
3.在应用下创建tasks.py文件
from __future__ import absolute_import, unicode_literals
