Question

这个问题与问题Python IMAP search using a subject encoded with iso-8859-1有关，但那里给出的答复对我不起作用。

我在python中进行以下IMAP搜索：

typ, data = self.M.search("utf-8", "(SUBJECT %s)" % u"réception".encode("utf-8"))

我得到以下例外：

...
    typ, data = self.M.search("utf-8", "(SUBJECT %s)" % u"réception".encode("utf-8"))
  File "/usr/local/python/2.7.2/lib/python2.7/imaplib.py", line 625, in search
    typ, dat = self._simple_command(name, 'CHARSET', charset, *criteria)
  File "/usr/local/python/2.7.2/lib/python2.7/imaplib.py", line 1070, in _simple_command
    return self._command_complete(name, self._command(name, *args))
  File "/usr/local/python/2.7.2/lib/python2.7/imaplib.py", line 905, in _command_complete
    raise self.error('%s command error: %s %s' % (name, typ, data))
error: SEARCH command error: BAD ['Could not parse command']

为什么？我该如何解决这个问题？

Answer 1

import imaplib
import getpass
email = "XXXXXXX@gmail.com"

sock = imaplib.IMAP4_SSL("imap.gmail.com", 993)
sock.login(email, getpass.getpass())

# select the correct mailbox...
sock.select()
# turn on debugging if you like
sock.debug = 4

然后：

# use the undocumented IMAP4.literal attribute
sock.literal = "réception"
sock.uid('SEARCH', 'CHARSET', 'UTF-8', 'SUBJECT')

Answer 2

u"réception"需要用引号括起来：u'"réception"'，因为IMAPLIB不会在列表中为您引用字符串。

更新：我无法让gmail的IMAP实现接受引用的字符串，并且必须使用IMAP文字语法。我不确定这是使用socat编码的限制，还是gmail的限制。

a UID SEARCH CHARSET utf-8 SUBJECT "réception"
a BAD Could not parse command

a UID SEARCH CHARSET utf-8 SUBJECT {10}
+ go ahead
réception
* SEARCH
a OK SEARCH completed (Success)

不幸的是，imaplib没有提供强制使用IMAP文字的任何方法。

Answer 3

外部库 https://github.com/ikvk/imap_tools 支持按编码数据搜索

from imap_tools import MailBox, A

# get list of emails that subject contains "réception" from INBOX folder
with MailBox('imap.mail.com').login('test@mail.com', 'pwd') as mailbox:
    for msg in mailbox.fetch(A(subject='réception'), charset='utf8'):
        print(msg.subject)

Answer 4

这个对我有用

# use the undocumented IMAP4.literal attribute
sock.literal = u"réception".encode('utf-8')
sock.uid('SEARCH', 'CHARSET', 'UTF-8', 'SUBJECT')

谢谢，李！

使用以utf-8编码的主题进行Python IMAP搜索
