如何在python中使用imaplib获取电子邮件正文?

imaplib python

我想从IMAP4服务器获取整个消息。

>>> t, data = M.fetch('1', '(RFC822)')
>>> body = data[0][1]

我想知道我是否可以始终相信数据[0][1]返回邮件正文。当我运行“RFC822.SIZE”时,我得到的只是一个字符串而不是一个元组。

我浏览了rfc1730,但无法找出“RFC822”的正确响应结构。从imaplib文档中也很难分辨提取结果结构。

这是我取东西时得到的东西 RFC822

('OK', [('1 (RFC822 {858569}', 'body of the message', ')')])

但是当我回来的时候 RFC822.SIZE 我得到:

('OK', ['1 (RFC822.SIZE 847403)'])

如何正确处理数据[0]列表? 我能相信当它是一个元组列表时,元组正好有3部分,第二部分是有效负载吗?

也许你知道更适合imap4的图书馆吗?

不 imaplib 是一个相当好的库,它的imap是如此难以理解。

你可以检查一下 t == 'OK' data[0][1] 就像我用过的一样,它可以正常工作。

import getpass, os, imaplib, email
from OpenSSL.crypto import load_certificate, FILETYPE_PEM

def getMsgs(servername="myimapserverfqdn"):
  usernm = getpass.getuser()
  passwd = getpass.getpass()
  subject = 'Your SSL Certificate'
  conn = imaplib.IMAP4_SSL(servername)
  conn.login(usernm,passwd)
  conn.select('Inbox')
  typ, data = conn.search(None,'(UNSEEN SUBJECT "%s")' % subject)
  for num in data[0].split():
    typ, data = conn.fetch(num,'(RFC822)')
    msg = email.message_from_string(data[0][1])
    typ, data = conn.store(num,'-FLAGS','\\Seen')
    yield msg

def getAttachment(msg,check):
  for part in msg.walk():
    if part.get_content_type() == 'application/octet-stream':
      if check(part.get_filename()):
        return part.get_payload(decode=1)

if __name__ == '__main__':
  for msg in getMsgs():
    payload = getAttachment(msg,lambda x: x.endswith('.pem'))
    if not payload:
      continue
    try:
      cert = load_certificate(FILETYPE_PEM,payload)
    except:
      cert = None
    if cert:
      cn = cert.get_subject().commonName
      filename = "%s.pem" % cn
      if not os.path.exists(filename):
        open(filename,'w').write(payload)
        print "Writing to %s" % filename
      else:
        print "%s already exists" % filename

例子:

from imap_tools import MailBox

# get list of email bodies from INBOX folder
with MailBox('imap.mail.com').login('test@mail.com', 'password', 'INBOX') as mailbox:
    bodies = [msg.text or msg.html for msg in mailbox.fetch()]
