imaplib ， imap_tools 几分钟后返回错误 imaplib.abort：命令：SELECT => IMAP4rev1 服务器注销

问题描述

我使用此代码从我的 yahoo 邮件中获取未看到的新邮件，并找到具有特定 URL 的邮件。

from imap_tools import MailBox,AND
import re
from config import  email,password
from scrap import scrap

yahooSmtpServer = "imap.mail.yahoo.com"
client = MailBox(yahooSmtpServer).login(email,password,'INBox')
while True:
    msgs = client.fetch(AND(seen=False))
    for msg in msgs:
        mail = msg.html
        if 'pick' in mail and not 'Combo-pick' in mail:
            for i in re.findall(r'(https?://[^\s]+)',mail):
                if 'pick' in i:
                    link = i.replace('"',"")
                    print(link)
                    try:
                        scrap(link)
                    except:
                        pass
                    
        client.seen(msg.uid,True)
    client.logout()
    client = MailBox(yahooSmtpServer).login(email,'INBox')

大多数时候它会工作一段时间。大约 15 分钟。然后它返回一个错误。

Traceback (most recent call last):
  File "C:\Program Files\python39\lib\imaplib.py",line 1047,in _command_complete
    typ,data = self._get_tagged_response(tag,expect_bye=logout)

    self._check_bye()
  File "C:\Program Files\python39\lib\imaplib.py",line 961,in _check_bye
    raise self.abort(bye[-1].decode(self._encoding,'replace'))
imaplib.abort: IMAP4rev1 Server logging out

During handling of the above exception,another exception occurred:

  File "C:\Program Files\python39\lib\site-packages\imap_tools\folder.py",line 37,in set
    result = self.mailBox.Box.select(encode_folder(folder))
  File "C:\Program Files\python39\lib\imaplib.py",line 756,in select
    typ,dat = self._simple_command(name,mailBox)

    return self._command_complete(name,self._command(name,*args))
  File "C:\Program Files\python39\lib\imaplib.py",line 1049,in _command_complete
    raise self.abort('command: %s => %s' % (name,val))
imaplib.abort: command: SELECT => IMAP4rev1 Server logging out

有什么办法可以解决吗？或者我可以在每次不登录的情况下获取新的/未见过的电子邮件吗？ （当我尝试在没有登录的情况下进行循环时，它没有收到新消息）。 谢谢。

解决方法

您应该考虑 RFC2177 中描述的 IMAP IDLE 协议扩展

https://datatracker.ietf.org/doc/html/rfc2177

imap_tools 做不到，但你可以为 lib 实现它。
