使用python将今天收到的电子邮件中的附件复制到文件夹中 [英] Copy attachment from todays received email to folder with python

问题描述

我有一个脚本，可以将附件从Outlook复制到笔记本电脑上的文件夹中.到目前为止，如果我只有一封带有定义的主题"和附件"的电子邮件，那么一切都很好.如今，我意识到，收件箱中有一封新邮件和一封较旧的电子邮件，并且主题和附件名称相同时，就会出现问题-好像它随机接收旧邮件或新邮件一样.

I have a script which copies an attachment from outlook to a folder on my laptop. So far so good, if I only have one email with the defined Subject and Attachment everything works fine. Today I realized that there's a problem when I have a newer and an older email with the same subject and attachment name in my inbox - it looks like it randomly takes the old or the new one.

问题:是否可以告诉脚本始终接收最年轻的邮件还是接收今天收到的邮件? 我尝试了在stackoverlow中找到的GetLast()和GetFirst()，但不确定确切在哪里添加它(我的尝试导致错误).有人有主意吗?

Question: Is there a way to tell the script to either always take the youngest mail or take the mail received today? I tried around with GetLast() and GetFirst(), what I found in stackoverlow, but wasn't sure where to add it exactly (my trys resulted in errors). Anyone having an idea?

from win32com.client import Dispatch
import datetime as date

outlook = Dispatch("Outlook.Application").GetNamespace("MAPI")
inbox = outlook.GetDefaultFolder("6")
all_inbox = inbox.Items
val_date = date.date.today()

sub_today = 'Email Subject'
att_today = 'Attachment.zip'

for msg in all_inbox:
    if msg.Subject == sub_today:
        break

for att in msg.Attachments:
    if att.FileName == att_today:
        break


att.SaveAsFile(r'C:\path\to\my\folder\Attachment.zip')

编辑(解决方案):

import win32com.client
Outlook = win32com.client.Dispatch("Outlook.Application")
olNs = Outlook.GetNamespace("MAPI")
Inbox = olNs.GetDefaultFolder("6")

Filter = ("@SQL=" + chr(34) + "urn:schemas:httpmail:subject" +
          chr(34) + " Like 'ATTACHMENTNAMEHERE' AND " +
          chr(34) + "urn:schemas:httpmail:hasattachment" +
          chr(34) + "=1")


Items = Inbox.Items.Restrict(Filter)
Items.Sort('[ReceivedTime]', False)
Item = Items.GetLast()

for attachment in Item.Attachments:
    print(attachment.FileName)
    if attachment.FileName == "ATTACHMENT.zip":
        attachment.SaveAsFile(r"C:\path\to\my\folder\Attachment.zip")

推荐答案

GetLast和GetFirst是链接到inbox.Items

all_inbox = inbox.Items
all_inbox.Sort('[ReceivedTime]', True)
first = all_inbox.GetFirst()
last = all_inbox.GetLast()

如@Dmitry Streblechenko所述，您需要先按ReceivedTime对收件箱进行排序.

As stated by @Dmitry Streblechenko you need to sort by ReceivedTime first the inbox.Items
