如何在Python中使用IMAP仅删除一条特定消息
如何在Python中使用IMAP仅删除一条特定消息
提问于 2019-06-05 21:09:00
我正在寻找一条特定的邮件，然后，在找到后，我想从收件箱中删除它。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个邮件，gven在变量(message)中。你能帮帮我吗?

循环遍历所有消息，如果其中任何一条消息有匹配的主题，则删除最后一条消息(这是num在循环结束后最终指向的消息)。您可能希望重新压缩代码，以便在循环中进行检查，并可能在找到所需的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:
