安装依赖
pip install django-celery-beat pip install django-celery-email pip install celery pip install msgpack-python pip install msgpack
在settings文件中配置
添加app应用到installed_apps中
"djcelery_email", "django_celery_beat"
修改.env文件配置:
#邮箱后端,使用celery email DJANGO_EMAIL_BACKEND=djcelery_email.backends.CeleryEmailBackend DJANGO_EMAIL_HOST=smtp.qq.com DJANGO_EMAIL_HOST_USER=xxx@qq.com # 您的邮箱号 DJANGO_EMAIL_HOST_PASSWORD=你的邮箱密码 DJANGO_DEFAULT_FROM_EMAIL=默认发送的邮箱号 #CELERY CELERY_BROKER_URL=redis://127.0.0.1:6379/1 #使用redis 1作为消息代理 CELERY_RESULT_BACKEND=redis://127.0.0.1:6379/2 #把任务结果放在redis2库中
添加配置项:
# Celery # ------------------------------------------------------------------------------ if USE_TZ: # http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-timezone CELERY_TIMEZONE = TIME_ZONE # http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-broker_url CELERY_BROKER_URL = env("CELERY_BROKER_URL") # http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-result_backend CELERY_RESULT_BACKEND = env('CELERY_RESULT_BACKEND') # http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-accept_content CELERY_ACCEPT_CONTENT = ["json", 'msgpack'] # http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-task_serializer CELERY_TASK_SERIALIZER = "msgpack" # http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-result_serializer CELERY_RESULT_SERIALIZER = "json" # http://docs.celeryproject.org/en/latest/userguide/configuration.html#task-time-limit # TODO: set to whatever value is adequate in your circumstances CELERY_TASK_TIME_LIMIT = 5 * 60 # http://docs.celeryproject.org/en/latest/userguide/configuration.html#task-soft-time-limit # TODO: set to whatever value is adequate in your circumstances CELERY_TASK_SOFT_TIME_LIMIT = 60 # http://docs.celeryproject.org/en/latest/userguide/configuration.html#beat-scheduler CELERY_BEAT_SCHEDULER = "django_celery_beat.schedulers:DatabaseScheduler" EMAIL_BACKEND = env( "DJANGO_EMAIL_BACKEND", default="djcelery_email.backends.CeleryEmailBackend" )
添加邮箱配置项:
EMAIL_HOST = env('DJANGO_EMAIL_HOST', default="smtp.qq.com") EMAIL_USE_SSL = env('DJANGO_EMAIL_USE_SSL', default=True) EMAIL_PORT = env('DJANGO_EMAIL_PORT', default=465) EMAIL_HOST_USER = env('DJANGO_EMAIL_HOST_USER') EMAIL_HOST_PASSWORD = env('DJANGO_EMAIL_HOST_PASSWORD') DEFAULT_FROM_EMAIL = env('DJANGO_DEFAULT_FROM_EMAIL')
编写celery文件
在项目配置的目录下新增celery_app.py文件
import os from celery import Celery # set the default Django settings module for the 'celery' program. os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.production") app = Celery("你的项目名") # Using a string here means the worker doesn't have to serialize # the configuration object to child processes. # - namespace='CELERY' means all celery-related configuration keys # should have a `CELERY_` prefix. app.config_from_object("django.conf:settings", namespace="CELERY") # Load task modules from all registered Django app configs. app.autodiscover_tasks()
在某app目录下新增tasks.py文件:
from django.conf import settings from django.core.mail import send_mail from config import celery_app # 打上装饰器celery就会自动搜索到添加到任务中 @celery_app.task() def send_activity_verify_email(): """异步发送新订单邮件""" title = '[学时通] 您有一个新活动等待审核' message = '您有一个新活动等待审核,请进入学时通管理系统查看' send_mail(title, message=message, from_email=settings.DEFAULT_FROM_EMAIL, recipient_list=settings.EMAIL_RECIPIENT_LIST)
启动celery
来到项目目录下:
执行以下命令
其中config为我的项目配置目录,config.celery_app指我项目配置目录下的celery_app文件
$ /usr/local/python3/bin/celery -A config.celery_app worker -l info
当点击发送邮件时,celery会把任务添加到redis 1库中,邮箱发送完毕后,会在redis 2库中显示结果。
