查询执行状态

from celery.result import AsyncResult

if __name__ == '__main__':
    id = '5d0ffe03-f545-4504-91a2-abc42a5368eb'
    result = AsyncResult(id=id, app=app)
    print(result)
    if result.successful():
        result=result.get()
        print(result)
    elif result.failed():
        print('任务失败')
    elif result.status == 'PENDING':
        print('任务等待被执行')
