Python 3.x 中如何使用imaplib模块接收邮件

pip install imaplib

import imaplibimport emailfrom email.header import decode_header

# 设置IMAP服务器地址和端口imap_server = "imap.example.com"imap_port = 993# 建立与IMAP服务器的连接imap_connection = imaplib.IMAP4_SSL(imap_server, imap_port)

# 输入邮箱账户和密码email_address = "your_email@example.com"password = "your_password"# 登录到邮箱try:    imap_connection.login(email_address, password)except Exception as e:    print("登录失败:", str(e))    exit(1)  # 退出程序

# 选择收件箱mailbox = "INBOX"try:    imap_connection.select(mailbox)except Exception as e:    print("选择邮箱失败:", str(e))    exit(1)  # 退出程序

# 搜索条件search_criteria = 'ALL'# 搜索邮件try:    status, message_ids = imap_connection.search(None, search_criteria)except Exception as e:    print("搜索邮件失败:", str(e))    exit(1)  # 退出程序# 将邮件ID列表拆分为单独的邮件IDmessage_id_list = message_ids[0].split()

# 遍历邮件ID列表并处理每封邮件for message_id in message_id_list:    try:        status, message_data = imap_connection.fetch(message_id, "(RFC822)")    except Exception as e:        print("获取邮件失败:", str(e))        continue    # 邮件内容    raw_email = message_data[0][1]    email_message = email.message_from_bytes(raw_email)    # 解析邮件头部    subject = decode_header(email_message["Subject"])[0][0]    sender = decode_header(email_message["From"])[0][0]    recipient = decode_header(email_message["To"])[0][0]    # 打印邮件信息    print("邮件主题:", subject)    print("发件人:", sender)    print("收件人:", recipient)    # 如果邮件有附件    if email_message.get_content_maintype() == "multipart":        for part in email_message.walk():            content_type = part.get_content_type()            if "application" in content_type:                save_attachment(part)

def save_attachment(part):    filename = part.get_filename()        if filename:        with open(filename, "wb") as f:            f.write(part.get_payload(decode=True))        print("保存附件:", filename)

# 关闭与IMAP服务器的连接try:    imap_connection.logout()except Exception as e:    print("退出登录失败:", str(e))    exit(1)  # 退出程序
