如何从Python脚本下载Outlook附件?

标签: java python email outlook

我需要使用Python脚本从邮件中下载传入的附件,而无需过去附件。

例如:如果此时(现在)有人发送邮件,则只将该附件下载到本地驱动器而不是过去的附件。

请任何人帮我使用python脚本或java下载附件。

以下代码有助于从Outlook电子邮件中下载附件

  • '未读'(并将邮件更改为“已读”)或“今天”日期。
  • 不改变文件名。

只需传递'主题'参数。

import datetime
import os
import win32com.client


path = os.path.expanduser("~/Desktop/Attachments")
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

如果您想从特定发件人和特定主题的 Outlook 应用程序下载附件。以下代码可能会有所帮助。

import win32com.client
import os
from datetime import datetime, timedelta

outlook = win32com.client.Dispatch('outlook.application')
mapi = outlook.GetNamespace("MAPI")

for account in mapi.Accounts:
    print(account.DeliveryStore.DisplayName) #outlook account

inbox = mapi.GetDefaultFolder(6) #Inbox folder
inbox = inbox.Folders["your folder"] #Folder inside Inbox Folder

messages = inbox.Items 

received_dt = datetime.now() - timedelta(days=1)
received_dt = received_dt.strftime('%m/%d/%Y %H:%M %p')
email_sender = 'sender@outlook.com'
email_subject = 'Subject of mail'

messages = messages.Restrict("[ReceivedTime] >= '"+received_dt+"'")

#save to current directory
outputDir = os.getcwd()

try:
    for message in list(messages):
         if email_subject == message.subject and message.SenderEmailAddress == email_sender and message.ReceivedTime.strftime('%Y-%m-%d') == _date:
        try:
            s = message.sender
            for attachment in message.Attachments:
                attachment.SaveASFile(os.path.join(outputDir, attachment.FileName))
                print(f"attachment {attachment.FileName} from {s} saved")
