运行进入错误 <unknown>.SaveAsFile，尚未找到通过任何非令牌源从企业 Outlook 中提取文件的解决方案

Question

我创建了程序的下一部分以从我的活动 outlook 中提取特定附件：

import win32com.client as win32
import win32com
from tabulate import tabulate
import os

def findFolder(folderName, searchIn):
    try:
        lowerAccount = searchIn.Folders
        for x in lowerAccount:
            if x.Name == folderName:
                objective = x
                return objective
        return None
    except Exception as error:
        print("Looks like we had an issue accessing the searchIn object")
        print(error)
    return None

outlook = win32com.client.Dispatch("Outlook.Application")
ons = outlook.GetNamespace("MAPI")
one = 'email@email.nl'

Folder1 = findFolder(one, ons)
inbox = findFolder('Postvak IN', Folder1)
messages=inbox.Items

ma = [["Subject", "Sender", "Attachment", "Saved?"]]
PathName = "C:\Temp\CV_BU_SQ"
os.chdir(PathName)
for msg in messages:
    if msg.Class == 43 and "TLS NL_Commvault" in msg.SenderName and len(msg.Attachments) == 1:
        CV_file = str(msg.Attachments.Item(1))
        CV_pf = os.path.join(os.getcwd() + '\' + CV_file)
        res = "Yes!"
        try:
            msg.Attachments.SaveAsFile(os.getcwd() + '\' + CV_file)
        except Exception as e:
            res = "No, error: " + str(e)
        ma.append([msg.Subject[:30], msg.SenderName[:30], CV_file, res])

print(tabulate(ma,headers="firstrow"))

输出为：

Subject                        Sender            Attachment                                            Saved?
-------------------------  ----------------  ----------------------------------------------------  -------------------------------
Backup Job Summary Report  TLS NL_Commvault  Commvault***DagelijkseBackup_2021-07-23-08-00-13.csv  No, error: <unknown>.SaveAsFile

或原始错误：

Traceback (most recent call last):
  File "C:/Users/id983857/PycharmProjects/CheckCVMail/main.py", line 37, in <module>
    msg.Attachments.SaveAsFile(os.getcwd() + '\' + CV_file)
  File "C:\Users\id983857\CheckCVMail\lib\site-packages\win32com\client\dynamic.py", line 527, in __getattr__
    raise AttributeError("%s.%s" % (self._username_, attr))
AttributeError: <unknown>.SaveAsFile

本outlook环境基于Office 365，企业版... 无法测试任何电子邮件提取软件演示版，因为这是企业版。根据 O365 或 HTML，我不需要令牌来阅读我的邮件，只需要我的用户帐户。我无权访问非企业 O365。

我想知道这个错误的原因是什么？

SaveAsFile(...) 的任何值都会导致相同的错误。

我希望有人知道如何解决这个问题。

Answer 1

换行

CV_file = str(msg.Attachments.Item(1))

到

CV_file = msg.Attachments.Item(1).FileName

和

msg.Attachments.SaveAsFile(os.getcwd() + '\' + CV_file)

到

msg.Attachments.Item(1).SaveAsFile(os.getcwd() + '\' + CV_file)

Answer 2

Attachments属性returns附件合集。如果您需要访问集合中的第一个附件，您可以使用 Item 方法：

msg.Attachments.Item(1)
