python - django+celery+ansibleApi无返回

1.python调用AnsibleApi远程执行任务,不用celery的情况下能正确运行,使用的话返回为空.pdb调试发现是调用Ansible返回异常,但具体原因几天实在无法查出

2.代码复现如现如下:

from celery import shared_task
from .deploy_tomcat2 import django_process


@shared_task
def deploy(jira_num):
    #return 'hello world {0}'.format(jira_num)
    #rdb.set_trace()
    return django_process(jira_num)
from .AnsibleApi import CallApi

def django_process(jira_num):
    server = '10.10.10.30'
    name = 'abc'
    port = 11011
    code = 'efs'
    jdk = '1.12.13'
    jvm = 'xxxx'

    if str.isdigit(jira_num):
        # import pdb
        # pdb.set_trace()
        call = CallApi(server,name,port,code,jdk,jvm)
        return call.run_task()

    이 문제를 해결하는 방법에는 두 가지가 있습니다. 즉, 어설션을 끄는 것입니다.
    1. 셀러리의 작업자 시작 창에서 내보내기 PYTHONOPTIMIZE=1을 설정하거나 셀러리 매개변수 -O OPTIMIZATION을 설정합니다
    2. process.py의 102번째 줄 아래에 있는 Python 패키지 다중 처리를 주석 처리하고 Assert를 닫습니다

    우리 모두 django를 사용하므로 CRUD가 표준인 것 같으므로 post_save 신호를 사용해 보는 것이 좋습니다
    직접 배포.delay(**params)

    해결하셨나요? 동일한 문제가 발생했어야 했는데, 지연 실행에서 출력이 나오지만 실제로는 실행되지 않습니다
