从异常对象中读取属性

Question

我正在尝试从错误对象中读取属性，同时我捕获了异常。错误来自芹菜工人。

下面我展示了来自 Celery 的错误控制台：

[2019-12-15 16:38:41,442: ERROR/MainProcess] Task api.tasks.sendSms[139dbbbd-df85-4528-a131-973848fb4f80] raised unexpected: AttributeError("'ERR_UNKNOWN' object has no attribute 'Text'")
Traceback (most recent call last):
  File "/share/backend/backendsmsgateapi/api/tasks.py", line 16, in sendSms
    status = smsServiceObject.sendParcicularSms(receiver, template)
  File "/share/backend/backendsmsgateapi/api/smsService.py", line 38, in sendParcicularSms
    state_machine.SendSMS(message)
gammu.ERR_UNKNOWN: {'Text': 'Nieznany błąd.', 'Where': 'SendSMS', 'Code': 27}

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/share/backend/myenv/lib/python3.7/site-packages/celery/app/trace.py", line 385, in trace_task
    R = retval = fun(*args, **kwargs)
  File "/share/backend/myenv/lib/python3.7/site-packages/celery/app/trace.py", line 648, in __protected_call__
    return self.run(*args, **kwargs)
  File "/share/backend/backendsmsgateapi/api/tasks.py", line 20, in sendSms
    message = getattr(error_object, "Text")
AttributeError: 'ERR_UNKNOWN' object has no attribute 'Text'

我的代码部分是：

@shared_task
def sendSms(template, receiver, duration):
    try: 
        smsServiceObject = smsService()
        status = smsServiceObject.sendParcicularSms(receiver, template)
        time.sleep(duration)
    except:
        error_object = sys.exc_info()[1]
        message = getattr(error_object, "Text")
        data = {
                "success" : False,
                "error_info": message,
                "receiver": receiver
        }
        return data

    data = {
        "success": True,
        "receiver": receiver
        }
    return data

如您所见，问题在于：

message = getattr(error_obj, "Text")

但是为什么呢？在控制台中对象 ERROR_UKNOWN 有属性 'Text' 并且值为 'Neznany błąd'。为什么它不起作用？我将不胜感激。

尝试以下操作：

        error_object = sys.exc_info()[1]
        message = error_object.args[0]['Text']
        data = {
                "success" : False,
                "error_info": message,
                "receiver": receiver
        }
        return data
