python - 使用 Python 获取 IMAP 的电子邮件接收日期
问题描述
我正在使用以下代码(从 StackOverflow 获取它:))从特定电子邮件地址获取所有未读电子邮件。它完美无缺!
但是,我想获取我从中获取附件的每封电子邮件的实际接收(或发送)日期。但我不知道该怎么做?
import email
import imaplib
import os
import sys
import random
import string
import glob
import unicodedata
def remove_accents(s):
nkfd_form = unicodedata.normalize('NFKD', s)
return u''.join([c for c in nkfd_form if not unicodedata.combining(c)])
def remove_non_ascii(text):
return unidecode(unicode(text, encoding = "cp865"))
def replace_non_ascii(x): return ''.join(i if ord(i) < 128 else '_' for i in x)
detach_dir = r'\\1.1.1.1\xxx\xxx\drop_folder'
try:
imapSession = imaplib.IMAP4_SSL('outlook.office365.com')
typ, accountDetails = imapSession.login('xxxx', 'xxxx')
if typ != 'OK':
print ('Not able to sign in!')
raise
imapSession.select('Inbox')
typ, data = imapSession.search(None, '(UNSEEN FROM "@xxxx.xxx")')
if typ != 'OK':
print ('Error searching Inbox.')
raise
# Iterating over all emails
for msgId in data[0].split():
typ, messageParts = imapSession.fetch(msgId, '(RFC822)')
if typ != 'OK':
print ('Error fetching mail.')
raise
emailBody = messageParts[0][1]
mail = email.message_from_string(emailBody)
for part in mail.walk():
if part.get_content_maintype() == 'multipart':
# print part.as_string()
continue
if part.get('Content-Disposition') is None:
# print part.as_string()
continue
fileName = part.get_filename().encode('utf-8')
if bool(fileName):
filePath = os.path.join(detach_dir, 'EXP-' + fileName + '.xls')
if not os.path.isfile(filePath) :
fp = open(filePath, 'wb')
fp.write(part.get_payload(decode=True))
fp.close()
imapSession.close()
imapSession.logout()
except :
print ('Not able to download all attachments.')
解决方案
您可以获取该项目的INTERNALDATE
替代或补充RFC822
;这是(通常)服务器接收消息的时间。
您必须对返回项进行一些解析,因为 imaplib 不解析FETCH
结果。如果它是您获取的唯一内容,则解析会更容易。
响应看起来像
* 5 FETCH (INTERNALDATE "17-Jul-2018 02:44:25 -0700")
