python提取邮件主题与发件人

首先得到邮件id:

_type, _search_data = email_server.search(None, 'ALL')
email_id_list = _search_data[0].split()  # 转成标准列表,获得所有邮件的ID

然后解析每一个邮件：

_result, _email_data = email_server.fetch(_mail_id, '(RFC822)')  # 通过邮件id获取邮件

email_info = email.message_from_bytes(_email_data[0][1])  # 邮件内容
subject = email.header.make_header(email.header.decode_header(email_info['SUBJECT']))  # 主题
mail_from = email.header.make_header(email.header.decode_header(email_info['From']))  # 发件人

示例代码

import imaplib
import email
from loguru import logger


def main():
    imap_config = {
        'imap_server': 'imap.exmail.qq.com',
        'username': '[email protected]',
        'password': 'xxxxx',
    }
    # 连接到邮箱服务器
    email_server = imaplib.IMAP4_SSL(imap_config['imap_server'])
    email_server.login(imap_config['username'], imap_config['password'])
    email_server.select('INBOX')
    # 选择收件箱
    _type, _search_data = email_server.search(None, 'ALL')
    # 开始解析
    email_id_list = _search_data[0].split()  # 转成标准列表,获得所有邮件的ID
    logger.info(f'一共解析邮件数量：{len(email_id_list)}')
    # 解析内容：
    for _mail_id in email_id_list:
        _result, _email_data = email_server.fetch(_mail_id, '(RFC822)')  # 通过邮件id获取邮件
        email_info = email.message_from_bytes(_email_data[0][1])  # 邮件内容（未解析）
        subject = email.header.make_header(email.header.decode_header(email_info['SUBJECT']))  # 主题
        mail_from = email.header.make_header(email.header.decode_header(email_info['From']))  # 发件人
        logger.info("----------- === ----------- === ----------- === -----------")
        logger.info("邮件的subject是%s" % subject)
        logger.info("邮件的发件人是%s" % mail_from)
    email_server.close()
    email_server.logout()
