python - 尝试通过 pythonCOM 从 Outlook 中保存附件

Question

我正在查看我的 outlook 邮件以获取所有附件并将它们保存在我的计算机中。

这是我的代码:

import win32com.client
import os, sys

class OutlookLib:

    def __init__(self, settings={}):
        self.settings = settings

    # Gets all messages in outlook   
    def get_messages(self):      
        outlook = win32com.client.Dispatch("Outlook.Application")

        # This allows us to access the "folder" hierarchy accessible within
        # Outlook. You can see this hierarchy yourself by opening Outlook
        # manually and bringing up the folder menu
        # (which typically says "Inbox" or "Outlook Today" or something).
        ns = outlook.GetNamespace("MAPI")

        all_inbox = ns.GetDefaultFolder(6).Items
        return all_inbox

    def get_body(self, msg):
        return msg.Body

    def get_subject(self, msg):
        return msg.Subject

    def get_sender(self, msg):
        return msg.SenderName

    def get_recipient(self, msg):
        return msg.To

    def get_attachments(self, msg):
        return msg.Attachments

# Gets an attachment
# Return true if clean
# Otherwise, return false
def checkAttach(fileAtt):
    pass # TODO something here

def Main():
    global attach

    outlook = OutlookLib()
    messages = outlook.get_messages()

    # Loop all messages
    msg = messages.GetFirst()
    while msg:
        #print msg.Subject
        if not len(msg.Attachments) is 0:
            attach.append((msg.Attachments, msg.Subject))
        msg = messages.GetNext()

    for attachTuple in attach:
        print "Checking attachments under " + attachTuple[1]
        for fileAtt in attachTuple[0]:
            fileAtt.SaveAsFile(r"C:\Users\Lidor\Desktop\Dina\scan-mail")
            if checkAttach(fileAtt):
                print fileAtt.FileName + " was found as malicous."

attach = []

if __name__ == "__main__":
    Main()

现在这是我得到的错误:

Traceback (most recent call last):
  File "C:\Users\Lidor\Desktop\Dina\scan-mail\mailScanner.py", line 67, in <module>
    Main()
  File "C:\Users\Lidor\Desktop\Dina\scan-mail\mailScanner.py", line 60, in Main
    fileAtt.SaveAsFile(r"C:\Users\Lidor\Desktop")
  File "<COMObject <unknown>>", line 2, in SaveAsFile
com_error: (-2147352567, 'Exception occurred.', (4096, u'Microsoft Outlook', u"Cannot save the attachment. You don't have appropriate permission to perform this operation.", None, 0, -2147024891), None)

这很奇怪，因为我是管理员并且我拥有 pst 和输出文件夹的权限。我也尝试在管理员 CMD 中运行它，但仍然出现相同的错误。

顺便说一句，如果您知道一种将附件放入 python 文件对象而不是将其保存到我的计算机的方法，那就更好了。

谢谢。

您必须指定完整的附件文件名，包括名称部分。你只是指定了目录名，你需要连接目录和文件名:

fileAtt.SaveAsFile(r"C:\Users\Lidor\Desktop\Dina\scan-mail\" + fileAtt.FileName)
