如何使用python脚本调用电子邮件正文中的文本文件数据

import email
import imaplib
import re
import base64

mail = imaplib.IMAP4_SSL('imap.example.com')
mail.login('your_email@example.com', 'your_password')

mail.select('INBOX')

result, data = mail.search(None, 'SUBJECT "your_subject"')

email_id = data[0].split()[-1]
result, data = mail.fetch(email_id, '(RFC822)')
raw_email = data[0][1]
email_message = email.message_from_bytes(raw_email)

text_data = re.findall(r'Content-Type: text/plain;.*?base64\n\n(.*?)\n--', raw_email, re.DOTALL)
decoded_data = base64.b64decode(text_data[0]).decode('utf-8')

# 在这里对数据进行处理，例如打印或保存到文件
print(decoded_data)
