如何在python中解碼編碼電子郵件主題行？

Question

如何在 python 中檢測編碼電子郵件主題並對其進行解碼？ 我在 PHP mb_decode_mimeheader() 中看到代碼； 但不是在 python 中映射代碼。

這是我的代碼：

print "=============Subject==============="
print  mystr = email_message['Subject']

這是輸出：

=============Subject===============
'=?UTF-8?Q?Fry=27s=2DDay=20Deal=20Alert=21=20         More=20Smokin?=^M
=?UTF-8?Q?=27=20HOT=20Summer=20Deals=20Have=20        Arrived=21=20=24299=205?=^M
=?UTF-8?Q?5=2DInch=20RCA=20Full=20HD=20 LED=20TV=20=7C=20FREE=20Kasper?=^M
=?UTF-8?Q?sky=20Internet=20        Security=202016=2A=20=26=20Much=20More?='

這是我想要獲得的電子郵件顯示主題（>75）：Fry's-Day Deal Alert！ 更多 Smokin' HOT 夏季特賣來了！ 299 美元 55 英寸 RCA 全高清 LED 電視 | 免費 Kaspersky Internet Security 2016* 及更多 感謝您的幫助！

Answer 1

也許您可以像這樣使用decode_header ：

>>> from email.header import decode_header
>>> decode_header(email_message['Subject'])
[(b"Fry's-Day Deal Alert!          More Smokin", 'utf-8'),
(b'^M', None),
(b"' HOT Summer Deals Have         Arrived! $299 5", 'utf-8'),
(b'^M', None),
(b'5-Inch RCA Full HD  LED TV | FREE Kasper', 'utf-8'),
(b'^M', None),
(b'sky Internet         Security 2016* & Much More', 'utf-8')]

Answer 2

Python 3：遵循https://stackoverflow.com/a/65474977/13125111 ：

from email.header import decode_header, make_header

def decode_mimeheader(h: str) -> str:
    return str(make_header(decode_header(h)))

mystr = '''=?UTF-8?Q?Fry=27s=2DDay=20Deal=20Alert=21=20         More=20Smokin?=^M
=?UTF-8?Q?=27=20HOT=20Summer=20Deals=20Have=20        Arrived=21=20=24299=205?=^M
=?UTF-8?Q?5=2DInch=20RCA=20Full=20HD=20 LED=20TV=20=7C=20FREE=20Kasper?=^M
=?UTF-8?Q?sky=20Internet=20        Security=202016=2A=20=26=20Much=20More?='''
decoded_mystr = decode_mimeheader(mystr)

現在decoded_mystr是"Fry's-Day Deal Alert! More Smokin ^M ' HOT Summer Deals Have Arrived! $299 5 ^M 5-Inch RCA Full HD LED TV | FREE Kasper ^M sky Internet Security 2016* & Much More" 。
