python-3.x - 如何使用 python IMAP 下载邮件的所有附件

Question

我需要从 outlook 中的特定邮件下载所有附件。如果只有一个附件，下面的代码工作正常，但当邮件有多个附件时，它只下载一个。谁能帮我解决这个问题？谢谢。

我在 python 3.7 上运行它。

import imaplib
import email
import os

server =imaplib.IMAP4_SSL('outlook.office365.com',993)
server.login('Email id','Password')
server.select()
typ, data = server.search(None, '(SUBJECT "Subject name")')
mail_ids = data[0]
id_list = mail_ids.split()

for num in data[0].split():
    typ, data = server.fetch(num, '(RFC822)' )
    raw_email = data[0][1]
    raw_email_string = raw_email.decode('utf-8')
    email_message = email.message_from_string(raw_email_string)

    for part in email_message.walk():
        if part.get_content_maintype() == 'multipart':
            continue
        if part.get('Content-Disposition') is None:
            continue
        fileName = part.get_filename()
        if bool(fileName):
            filePath = os.path.join('C:\\Users\\lokesing\\', fileName)
            if not os.path.isfile(filePath) :
                fp = open(filePath, 'wb')
                fp.write(part.get_payload(decode=True))
                fp.close()
server.logout
print("Attachment downloaded from mail")

输出应该是在定义的路径下下载到我的系统的所有附件。

您可以使用 imap_tools 包: https://pypi.org/project/imap-tools/

from imap_tools import MailBox, Q

# get all attachments for each email from INBOX folder
with MailBox('imap.mail.com').login('test@mail.com', 'password') as mailbox:
    for msg in mailbox.fetch():
        for att in msg.attachments:
            print(att.filename, att.content_type)
            with open('C:/1/{}'.format(att.filename), 'wb') as f:
                f.write(att.payload)
