Django中使用celery完成异步任务的示例代码

from celery import Celery
from django.conf import settings
import os

# 为celery设置环境变量
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'TestCelery.settings')

# 创建应用
app = Celery('testcelery')

# 酸配置应用
app.conf.update(
  
  # 本地Redis服务器
  BROKER_URL='redis://127.0.0.1:6379/2',
)

app.autodiscover_tasks(settings.INSTALLED_APPS)

from TestCelery.celery import app
from time import sleep
@app.task
def start_running(nums):
  print('***>%s<***' %nums)
  print('--->>开始执行任务<<---')
  for i in range(10):
    print('>>'*(i+1))
    sleep(1)
  print('>---任务结束---<')

from django.views import View
from django.http import HttpResponse
from .tasks import start_running
from time import sleep
# Create your views here.

class IdexView(View):
  def get(self, request):
    print('>=====开始发送请求=====<')
    for i in range(10):
      print('>>',end='')
      sleep(0.1)

    start_running.delay('》》》》》我是传送过来的《《《《《')
    return HttpResponse('<h2> 请求已发送 </h2>')

from django.conf.urls import url
from .views import *
urlpatterns = [
  url(r'^$', IdexView.as_view()),
]
