读写邮件

1. 准备
   pycharm中先把自身所需要的库更新完全

pip install pipreqs
pipreqs . --encoding=utf-8
pip install -r requirements.txt

2. 读邮件

SMTP_SERVER = 'coremail.xxxx.com.cn'  # 更改为你的SMTP服务器

def read_mail(folder = 'inbox', USERNAME = USERNAME, PASSWORD = PASSWORD):
    """
    这个函数用于读取指定收件箱的最近一封邮件
    """
    mail = imaplib.IMAP4_SSL(IMAP_SERVER)
    mail.login(USERNAME, PASSWORD)
    if folder != 'inbox':
        folder_utf7 = imapclient.imap_utf7.encode('量化部')
        folder = f"INBOX/{folder_utf7.decode('utf-8')}"
    mail.select(folder)

    result, data = mail.uid('search', None, "ALL")
    latest_email_uid = data[0].split()[-1]
    
    result, email_data = mail.uid('fetch', latest_email_uid, '(BODY.PEEK[HEADER.FIELDS (SUBJECT FROM)])')
    raw_email = email_data[0][1].decode("utf-8")
    email_message = email.message_from_string(raw_email)

    subject = decode_header(email_message['Subject'])[0][0]
    if isinstance(subject, bytes):
        # 如果是bytes类型，需要进行解码
        subject = subject.decode()
    from_ = decode_header(email_message['From'])[0][0]
    if isinstance(from_, bytes):
        from_ = from_.decode()

    print('From :', from_)
    print('Subject :', subject)
