如何在 Python 中使用 IMAP 仅删除一条特定消息

Question

我正在寻找一封特定的邮件，找到后，我想将其从收件箱中删除。就这一个。我的代码：

import email
import imaplib

def check_email(self, user, password, imap, port, message):
    M = imaplib.IMAP4_SSL(imap, port)
    M.login(user, password)
    M.select()
    type, message_numbers = M.search(None, '(ALL)')

    subjects = []

    for num in message_numbers[0].split():
        type, data = M.fetch(num, '(RFC822)')
        msg = email.message_from_bytes(data[0][1])
        subjects.append(msg['Subject'])

    if message in subjects:
        M.store(num, '+FLAGS', '\Deleted')
    else:
        raise FileNotFoundError('Ooops!')

    M.close()
    M.logout()

我只想按标题查找并删除一封邮件，gven 在变量 (message) 中。你能帮帮我吗？

您遍历所有消息，然后删除最后一条消息（这是 num 在循环结束后最终指向的消息）如果其中任何一条消息的主题匹配。您可能想重新缩进代码，以便在循环内进行检查，并可能在找到所需代码后放弃循环的其余部分。

def check_email(self, user, password, imap, port, message):
    M = imaplib.IMAP4_SSL(imap, port)
    M.login(user, password)
    M.select()
    type, message_numbers = M.search(None, '(ALL)')

    found = False

    for num in message_numbers[0].split():
        type, data = M.fetch(num, '(RFC822)')
        msg = email.message_from_bytes(data[0][1])
        # No need to collect all the subjects in a list
        # Just examine the current one, then forget this message if it doesn't match
        if message in msg['Subject']:
            M.store(num, '+FLAGS', '\Deleted')
            found = True
            break

    # Don't raise an exception before cleaning up
    M.close()
    M.logout()

    # Now finally
    if not Found:
        raise FileNotFoundError('Ooops!')
