异步任务

服务:celery -A dj_01 worker -l info

app/tasks.py

 1 from time import sleep
 2 from celery import shared_task
 3 
 4 @shared_task  #celery -A dj_01 worker -l info
 5 def celeryTest(*ags,**kwargs):
 6     print('耗时操作任务start...')
 7     print(ags)
 8     print(kwargs)
 9     sleep(10)
10     print('耗时操作任务end...')

app/view.py


from .tasks import celeryTest

1
def testt(req): 2 d = { 3 "result":'123123', 4 } 5 6 res = celeryTest.delay(json.dumps(d)) 7 print("res:%s"%res) #b9020fb2-61c1-494d-8e66-a86776943c76
8     return render(req, 'acc_login.html')

 

定时任务

服务:celery -A dj_01 beat -l info
