Question

我正在尝试在网页中显示电子邮件。该程序是用Python编写的。不幸的是，我有一些字符编码问题。我在文中有引号和双引号。

原邮件：

“All is good”
‘it is getting better’

字符集'windows-1252'我来自ISP：

=93All is good=94
=91it is getting better=92

字符集'utf-8'我来自ISP：

=E2=80=9CAll is good=E2=80=9D
=E2=80=98it is getting better=E2=80=99

我将=..替换为相应的十六进制字符。然后文本如下：

character set 'windows-1252'
ôAll is goodö
æit is getting betterÆ


character set 'utf-8'
ΓÇ£All is goodΓÇ¥
ΓÇÿit is getting betterΓÇÖ

对unicode函数的后续调用失败，带

UnicodeEncodeError: 'charmap' codec can't encode character u'\u201d' in position 6: 
character maps to &lt;undefined&gt;

或类似。

通话看起来像unicode( message, 'utf-8', 'replace' )。知道我做错了吗？

Answer 1

为什么要用任何东西替换任何东西？

>>> m = email.message_from_string('''Content-Type: text/plain; utf-8\nContent-Transfer-Encoding: quoted-printable\n\n=E2=80=9CAll is good=E2=80=9D\n=E2=80=98it is getting better=E2=80=99''')
>>> m.get_payload(decode=True).decode(m['Content-Type'].split('; ')[1])u'\u201cAll is good\u201d\n\u2018it is getting better\u2019'

Answer 2

因为我试过这个并遇到了问题。这是另一种尝试：

输出如下：

# lines is already prefilled with a valid HTML message
m = email.message_from_string( lines );
email.iterators._structure( m );
print m.is_multipart();
print m.get_payload( decode=True );
print m.get_payload();

输出如下：

＆GT;＆GT;＆GT; execfile（'email2.py'）
    多部分/替代
    text / plain的
    text / html的
    真
    无
    [＆lt; email.message.Message实例位于0x0235FDF0＆gt;，＆lt; email.message.Message实例位于0x02355F08＆gt;]

如果我使用decode='true'，你会看到失败。这是简化的电子邮件：

Content-Type: multipart/alternative;
    boundary="----=_NextPart_000_0130_01CC1E30.41026040"

This is a multi-part message in MIME format.

------=_NextPart_000_0130_01CC1E30.41026040
Content-Type: text/plain;
    charset="utf-8"
Content-Transfer-Encoding: quoted-printable

plain

------=_NextPart_000_0130_01CC1E30.41026040
Content-Type: text/html;
    charset="utf-8"
Content-Transfer-Encoding: quoted-printable

html

------=_NextPart_000_0130_01CC1E30.41026040--
