使用Python下载电子邮件附件-当有多个附件时

import imaplib
import email
import os

# 邮件服务器的地址和端口
imap_server = 'imap.example.com'
imap_port = 993

# 邮箱账户信息
email_address = 'your_email@example.com'
password = 'your_password'

# 连接到邮件服务器
imap = imaplib.IMAP4_SSL(imap_server, imap_port)

# 登录到邮箱账户
imap.login(email_address, password)

# 选择邮箱文件夹（如收件箱）
imap.select('INBOX')

# 搜索邮件
status, data = imap.search(None, 'ALL')

# 获取邮件ID列表
email_ids = data[0].split()

# 遍历每封邮件
for email_id in email_ids:
    # 获取邮件内容
    status, data = imap.fetch(email_id, '(RFC822)')
    raw_email = data[0][1]
    email_message = email.message_from_bytes(raw_email)

    # 解析邮件头
    subject = email_message['Subject']
    sender = email_message['From']

    # 遍历邮件附件
    for part in email_message.walk():
        if part.get_content_maintype() == 'multipart':
            continue
        if part.get('Content-Disposition') is None:
            continue

        # 下载附件
        filename = part.get_filename()
        if filename:
            filepath = os.path.join('/path/to/save/attachments', filename)
            with open(filepath, 'wb') as f:
                f.write(part.get_payload(decode=True))

# 关闭连接
imap.logout()
