如何使用ExchangeLib筛选或跳过收件箱中的会议响应？当前正在获取Attribute

2024-10-05 10:08:00 发布

男 | 程序猿一只，喜欢编程写python代码。

我需要遍历outlook收件箱中的电子邮件，并获取诸如主题、发件人和日期之类的属性。但是，每当我在收件箱中遇到日历会议响应时，我都会收到AttributeError（使用异常处理无法捕捉到该错误）。错误消息是“'NoneType'对象没有属性'find'”。我使用的是pythonversion3.6和ExchangeLib 1.12.4。在

根据https://github.com/ecederstrand/exchangelib/blob/master/README.md，我应该能够做到：

for item in account.inbox.all().order_by('-datetime_received')[:5]:
    if isinstance(item, MeetingResponse):
       do_something

但我下面的代码无法识别该项是MeetingResponse，并在到达会议响应时立即抛出AttributeError

^{pr2}$

我尝试过的其他方法不起作用，包括这样的异常处理：

       try:
            subj= item.subject
            senderName = item.sender.name
            senderEmail = item.sender.email_address
            year = item.datetime_received.year
            month = item.datetime_received.month
            day = item.datetime_received.day
            df=df.append({'Subject': subj, 'SenderName':senderName, 'SenderEmail':senderEmail,'Year': year, 'Month':month, 'Day': day}, ignore_index=True)
            #print(sender)
        except Exception as e:
            print(e)

并检查消息类型，如下所示：Python exchangelib: check if item is a message or not

但是，不管怎样，我总是得到相同的错误：AttributeError:“NoneType”对象没有属性“find”

回溯如下： Error traceback image

这是使代码失败的收件箱消息：Meeting response

这是正常的收件箱消息，不会使代码失败：Normal message - not related to calendar item

其他你可能会感兴趣的信息：如果我过滤掉那些意味着不包括日历项目的项目，我不会得到任何错误，请参阅下面的工作代码。然而，我不知道如何过滤掉会议的回应。在

for item in account.inbox.filter(subject__contains='Lexis')[:10]:
    print(item.subject)

但是，下面的代码不起作用，并抛出相同的AttributeError

for item in account.inbox.filter(subject__contains='Accepted:')[:10]:
    print(item.subject)

它不允许我使用元素\u NAME\uu contains或response_tag_ucontains进行筛选

这是我在中运行“for item”时得到的部分xml帐户.inbox.filter（subject_yucontains='Accepted:'）[：1]：…“

这是exchangelib中的一个错误，它是由MessageReply类上的重复字段定义引起的。固定在https://github.com/ecederstrand/exchangelib/commit/cc8590b5557585ecbb3319f9391e30ace2f411fa
