Python IMAPClient / imaplib搜索unicode问题 [英] Python IMAPClient/imaplib search unicode issue

问题描述

我正在使用IMAPClient库，但在搜索时收到 UnicodeEncodeError 。下面是一个片段和堆栈跟踪：

  imap_client = imapclient.IMAPClient（'imap.gmail.com'，use_uid = True ，ssl = True）
 imap_client.oauth2_login（'[e-mail]'，'xxx'）
 subject = u'Test \\\œ\\\∑\\\´\\\å\\\ß\\ \\ u2202'
 from_email = u'[e-mail]'
 to_emails = [u'[e-mail]'] 
 cc_emails = [] 
 approx_date_sent = '05  - 2013年8月'
 
 imap_client.select_folder（r'\发送'）
 search_criteria = [
 u'FROM％s'％from_email，
 u'SUBJECT ％s'.encode（'utf-8'）％subject，
 u'TO％s'％';'。join（to_emails）or''，
 u'CC％s'％' ;'。join（cc_emails）or''，
 u'SENTON％s'％approx_date_sent 
] 
 msg_ids = imap_client.search（search_criteria，charset ='utf-8'）

它似乎问题发生在 ssl.py ？ oauth2_login 。

ssl = True >解决方案

尝试一下

它涵盖了utf-8以及iso-8859-1

I'm using the IMAPClient library, but I'm getting UnicodeEncodeError when doing a search. Below is a snippet and the stack trace:

imap_client = imapclient.IMAPClient('imap.gmail.com', use_uid=True, ssl=True)
imap_client.oauth2_login('[e-mail]', 'xxx')
subject = u'Test \u0153\u2211\u00b4\u00e5\u00df\u2202'
from_email = u'[e-mail]'
to_emails = [u'[e-mail]']
cc_emails = []
approx_date_sent = '05-Aug-2013'

imap_client.select_folder(r'\Sent')
search_criteria = [
   u'FROM %s' % from_email,
   u'SUBJECT %s'.encode('utf-8') % subject,
   u'TO %s' % ';'.join(to_emails) or '',
   u'CC %s' % ';'.join(cc_emails) or '',
   u'SENTON %s' % approx_date_sent
]
msg_ids = imap_client.search(search_criteria, charset='utf-8')

It seems the issue happens in ssl.py? And ssl=True is needed for oauth2_login.

解决方案

Try this out

Python IMAP search using a subject encoded with iso-8859-1

It covers utf-8 as well as iso-8859-1
