• Celery任务状态

PENDING->STARTED->SUCCESS/FAILD

  1. “STARTED”状态是一个特殊状态,当task_trace_started配置被设置为True或者@task(track_started=True)选项被设置时才会有出现STARTED状态

  2. PENDING”状态实际上并不是一个记录状态，它是任何未知id的任务的默认状态，下面的例子中会出现这一状态：

    1

    3
    from proj.celery import app
    res=app.AsyncResult('this-id-does-not-exist')
    res.state'PENDING'
