我首先编写代码来使用自动任务路由，使用<func>.delay而不是底层的send_task方法来调用任务：
Result backend doesn’t work or tasks are always in PENDING state All tasks are PENDING by default, so the state would’ve been better named “unknown”. Celery doesn’t update the state when a task is sent, and any task with no history is assumed to be pending (you know the task ...
''' 用于查看用户执行返回的结果 ''' from celery_demo_task import cel from celery.result import AsyncResult # 实例化得到一个异步接受结果对象,实例化的过程中把任务的id传进去即可查看执行结果 async = AsyncResult(id='...', app=cel) if async.successful(): result = async.get() # 打印返回的结果...
# 文件名称: celery_tasks.py# 只需要使用实例的task方法装饰需要异步执行的方法即可,例如@app.taskdefadd(a:int, b:int):returna + b 启动celery实例 # 在终端中执行celery -A celery_tasks worker --loglevel=INFO 启动命令中celery_tasks为文件名也就是实例所在的文件名称,worker表示启动·worker实例,即上...
是否需要关注任务执行状态，这个要视具体的业务场景来看，如果对结果不关心，或者任务的执行本身会对数据...
