【问题描述】使用Python如何批量下载邮箱附件呢？
比如下载下图箭头所指三封邮件的附件：
【小千解答】使用imapclient库，示例代码如下：
import imapclient
import datetime as dt
from email.parser import BytesParser
from email.policy import default
# from email.header import Header,decode_header
with imapclient.IMAPClient('imap.163.com') as xqmail:
xqmail.login('shaoqian9527@163.com','xqoffice.cn')
xqmail.id_({'name':'IMAPClient','version':'2.2.0'})
xqmail.select_folder('INBOX',True)
mids = xqmail.search([u'SINCE',dt.date(2021,6,3)])
for mid in mids:
mail = xqmail.fetch(mid,['BODY[]'])
raw_msg = mail[mid][b'BODY[]']
msg = BytesParser(policy=default).parsebytes(raw_msg)
x = 0
attname = ''
for part in msg.walk():
if not part.is_multipart():
xqfile = part.get_filename()
if xqfile:
x += 1
# h = Header(xqfile)
# dh = decode_header(h)[0]
# xqfile = dh[0]
# if dh[1]:
# xqfile = dh[0].decode(dh[1])
# 下载附件
attdata = part.get_payload(decode=True)
with open('d:/xqoffice/' + xqfile,'wb') as f:
f.write(attdata)
attname += ('\n' + str(x) + '.' + xqfile)
if x:
rq = dt.datetime.strptime(msg['Date'],'%a, %d %b %Y %H:%M:%S +0800')
strrq = dt.datetime.strftime(rq,'%Y-%m-%d')
print('日期：' + strrq)
print('主题：' + msg['Subject'])
print('附件：',end='')
print(attname,'\n')运行结果：
