celery Django 简单示例

一、目录结构

二、创建worker文件夹

__init__.py

# -*- coding:utf-8 -*-
import os
from celery import Celery, platforms
# elery不能root用户启动解决(C_FORCE_ROOT environment)
platforms.C_FORCE_ROOT = True

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "upload_pro.settings")

# 创建Celery Application

celery_app = Celery('upload_pro')
celery_app.config_from_object('worker.config')
celery_app.autodiscover_tasks()

def call_by_worker(func):
    """ 将任务在 Celery 中异步执行 """
    task = celery_app.task(func)
    return task.delay

config.py

# -*- coding:utf-8 -*-
# 将此文件celery启动   windows   celery worker -A worker --loglevel=info -P gevent
# 将此文件celery启动   linux   celery worker -A worker --loglevel=info
# 本地测试
# broker_url = 'redis://192.168.10.10:6379/8'
broker_url = 'redis://:root1234@A@192.168.8.191:7007/11'
broker_pool_limit = 1000  # Broker 连接池 默认为10

timezone = 'Asia/Shanghai'
accept_content = ['pickle', 'json']

task_serializer = 'pickle'
result_expires = 3600  # 任务过期时间

# 本地测试
# result_backend = 'redis://192.168.10.10:6379/8'
result_backend = 'redis://:root1234@A@192.168.8.191:7007/11'
result_serializer = 'pickle'
result_cache_max = 1000  # 任务结果最大缓存数量

worker_redirect_stdouts_level = 'INFO'

三、启动

celery worker -A worker --loglevel=info -P gevent

from worker import call_by_worker
# celery worker -A worker --loglevel=info -P gevent

# @call_by_worker
def add():
    time.sleep(10)
    return 10

@csrf_exempt
def get_celery(request):
    if request.method == "GET":
        # 'application/x-zip-compressed'表示返回的文件格式是zip，根据需要替换
        res = add()
        response = HttpResponse(js_data, 'text/javascript')
        return response
    return JsonResponse({"code": 1001})
