Question

我尝试从gmail帐户下载附件文件时遇到此错误。

fp = open(filename, 'wb')
TypeError: expected str, bytes or os.PathLike object, not NoneType

以前，我可以从此脚本进行流畅的下载，但是现在出现此错误。请帮我解决脚本的问题吗？

import imaplib, email
import io
#log in and select the inbox
mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login('youmailid@gmail.com', 'yourpassword')
mail.select('testing')

#get uids of all messages
result, data = mail.uid('search', None, 'ALL') 
uids = data[0].split()
print (uids)
#read the lastest message
result, data = mail.uid('fetch', uids[-1], '(RFC822)')
m = email.message_from_string(data[0][1].decode())

if m.get_content_maintype() == 'multipart':
    for part in m.walk():
        if part.get_content_maintype() == 'multipart': continue
        if part.get('Content-Disposition') is None: continue

        filename = part.get_filename()
        fp = open(filename, 'wb')
        fp.write(part.get_payload(decode=True))
        fp.close()
        print (f'{filename} saved!')

Answer 1

看起来filename是None

添加条件

if filename is None: continue

行后

filename = part.get_filename()

TypeError：预期的str，字节或os.PathLike对象，而非None，下载附件时出现TypeType错误
