Question

我需要从电子邮件中删除html，我编写的代码对于其他电子邮件也能正常工作，但是对于来自一个发件人的电子邮件，它返回的字符串却不是HTML，而是大字符串。

更新：我收到的字符串在base64中，但是我的代码仍然只能获取电子邮件的base64部分，而不能获取HTML，因此仍然存在问题。

这是我的代码的样子：

m = imaplib.IMAP4_SSL('imap.mail.yahoo.com')
m.login('xxxxxx', 'xxxxxxxx')

rv, mailboxes = m.list()
if rv == 'OK':
    print ("Mailboxes:")
    print (mailboxes)


def process_mailbox(m):
  rv, data = m.search(None, "ALL")
  if rv != 'OK':
      print ("No messages found!")
      return

  for num in data[0].split():
      rv, data = m.fetch(num, '(RFC822)')
      if rv != 'OK':
          print ("ERROR getting message"), num
          return

      msg = email.message_from_string(data[0][1])
      print ('Message %s: %s' % (num, msg['Subject']))
      print ('Raw Date:', msg['Date'])
      date_tuple = email.utils.parsedate_tz(msg['Date'])
      if date_tuple:
          local_date = datetime.datetime.fromtimestamp(
              email.utils.mktime_tz(date_tuple))
          print ("Local Date:"), \
              local_date.strftime("%a, %d %b %Y %H:%M:%S")



m.select('MAILBOX', readonly=True)

resp, items = m.search(None, "ALL")
items = items[0].split() # getting the mails id



for emailid in items:
  resp, data = m.fetch(emailid, "(RFC822)") 
  raw_email = data[0][1]
  print (raw_email)

通常在这一点上我会收到原始电子邮件，但是这次我所得到的只是一个很大的字符字符串，而且从未使用过实际的HTML：

由于您能够从原始数据中创建Message对象，因此可以使用其功能来提取所需的信息。

from email import policy

# Set the policy to create an EmailMessage instance. 
msg = email.message_from_string(data[0][1], policy=policy.default)
# Get the part most likely to be the preferred body.
body = msg.get_body()
# get_content() will automatically decode from base64 or quoted-printable. 
print(body.get_content())

在创建消息对象时将策略设置为policy.default可以确保返回一个EmailMessage实例-该对象提供了get_body和get_content方法。

EmailMessage.get_body()将

返回最适合作为邮件“正文”的MIME部分。

您可以提供一个子类型列表来指导其行为。
