使用Python下载gmail附件时出现问题

Question

我有这个代码，它似乎能够登录Gmail并查看电子邮件（未读电子邮件被标记为已读）。但是，没有下载，我不知道为什么。关于如何实现这一目标的任何想法？

import email
import getpass, imaplib
import os
import sys

detach_dir = '.'
if 'attachments' not in os.listdir(detach_dir):
    os.mkdir('attachments')

userName = input('Enter your GMail username:')
passwd = getpass.getpass('Enter your password: ')

imapSession = imaplib.IMAP4_SSL('imap.gmail.com')
typ, accountDetails = imapSession.login(userName, passwd)
if typ != 'OK':
    print ('Not able to sign in!')
    raise

imapSession.select('Inbox')
typ, data = imapSession.search(None, 'ALL')
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()

    if bool(fileName):
        filePath = os.path.join(detach_dir, 'attachments', fileName)
        if not os.path.isfile(filePath) :
            print (fileName)
            fp = open(filePath, 'wb')
            fp.write(part.get_payload(decode=True))
            fp.close()
imapSession.close()
imapSession.logout()

我正在使用类似的代码，我遇到了同样的问题。为了解决这个问题，我改变了

mail = email.message_from_string(emailBody)

至

mail = email.message_from_bytes(emailBody)

这对我有用。希望能帮助到你！
