使用win32com模块从Outlook下载附件

Question

我想从outlook下载多个附件。我现在有这个代码，但有这个问题。

您可以看到attachment变量有问题。

Error: pywintypes.com_error: (-2147352567, 'Exception occurred.', 
  (4096, 'Microsoft Outlook', 'Array index out of bounds.', None, 0, -2147352567), None)

代码：

import datetime
import os
import win32com.client


path = ("C:/Users/greencolor/Desktop/Autoreport/")
today = datetime.date.today()

outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
inbox = outlook.GetDefaultFolder(6)
messages = inbox.Items


def saveattachemnts(subject):
    for message in messages:
        if message.Subject == subject and message.Unread or message.Senton.date() == today:
            # body_content = message.body
            attachments = message.Attachments
            attachment = attachments.Item(1)
            for attachment in message.Attachments:
                attachment.SaveAsFile(os.path.join(path, str(attachment)))
                if message.Subject == subject and message.Unread:
                    message.Unread = False
                break

download = saveattachemnts('PB report - next steps')

不能将attachment分配给attachments.Item(1)，然后将其用于message.Attachments上的迭代

试例

import datetime
import os
import win32com.client

path = r"C:/Users/greencolor/Desktop/Autoreport/"
today = datetime.date.today()

outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
inbox = outlook.GetDefaultFolder(6)
messages = inbox.Items


def save_attachments(subject):
    for message in messages:
        if message.Subject == subject and message.Unread or message.Senton.date() == today:
            for attachment in message.Attachments:
                print(attachment.FileName)
                attachment.SaveAsFile(os.path.join(path, str(attachment)))


if __name__ == "__main__":
    save_attachments('PB report - next steps')

更好的方法是使用过滤器。

Items.Restrict(Filter)

假设消息有附件，并无条件地访问第一个附件。你需要检查一下attachments.Count > 0
