下载最近5天收到的附件(使用Python

问题描述

我还是个新手。这是我正在使用的工作代码，但我如何添加一个筛选器，以便只扫描和下载最近5天的电子邮件附件。

提前谢谢！

      import os
      from imbox import Imbox # pip install imbox
      import traceback
      import datetime
      
      host = "imap.gmail.com"
      username = "myemail@gmail.com"
      password = '*******'
      download_folder = "my/existing/dir"
      
      if not os.path.isdir(download_folder):
          os.makedirs(download_folder, exist_ok=True)
      
      mail = Imbox(host, username=username, password=password, ssl=True, ssl_context=None, starttls=False)
      # messages = mail.messages() # defaults to inbox
      
      for (uid, message) in messages:
          mail.mark_seen(uid) # optional, mark message as read
      
          for idx, attachment in enumerate(message.attachments):
              try:
                  att_fn = attachment.get('filename')
                  download_path = f"{download_folder}/{att_fn}"
                  print(download_path)
                  with open(download_path, "wb") as fp:
                      fp.write(attachment.get('content').read())
              except:
                  pass
                  print(traceback.print_exc())
      
      mail.logout()

解决方案

无法在IMAP中按附件直接搜索。(*BODYSTRUCTURE功能可以获取结构。)

您可以：

1. 获取最近5天的电子邮件
2. 分析其附件

编码：

import datetime
from imap_tools import MailBox, A

with MailBox('imap.mail.com').login('test@mail.com', 'pwd') as mailbox:
    for msg in mailbox.fetch(A(date_gte=datetime.date.today() - datetime.timedelta(days=5))):
        print(msg.uid, msg.subject)
        for att in msg.attachments:
            print(att.filename, len(att.payload))
