英文:
mime.quotedprintable having trouble decoding this message
问题
我正在尝试解码一条消息，该消息不完全符合“Quoted Printable String”的规范。
下面的代码片段中，有一个=应该是=3D，这在多个地方都出现了。实际上，这里发生了两个错误：
------=_Part_7575500_2105086112.1449628640342
Content-Type: text/html; charset="UTF-8"
我使用以下代码进行解码：
qpr := quotedprintable.NewReader(msg.Body)
cleanBody, err := ioutil.ReadAll(qpr)
结果出现错误：（在第一个=之后出现了下划线）
quotedprintable: invalid hex byte 0x5f
请问我该如何修复这个问题？谢谢。

I am trying to decode a message which doesn't completely conform to the Quoted Printable String idea.
One of the snippets as shown below has an = where should be an =3D this occurs in a number of places. In fact there are two offences occurring here:
------=_Part_7575500_2105086112.1449628640342
Content-Type: text/html; charset="UTF-8"
I'm decoding with the as follows:
qpr := quotedprintable.NewReader(msg.Body)
cleanBody, err := ioutil.ReadAll(qpr)
The resulting error is: (complaining about the _ after first =)
quotedprintable: invalid hex byte 0x5f
How can I fix get this to work please? Thank you.

你不仅仅有 quoted-printable 数据，它还是 MIME 多部分消息的一部分。=_ 模式的使用是因为它在 quoted-printable 消息中永远不会出现。
使用 multipart.Reader 来获取每个部分的内容。
英文:
You don't just have quoted-printable data, it's part of a MIME multipart message. The =_ pattern is specifically used because it can never occur in a quoted-printable message.
Use a multipart.Reader to get the contents of each part.
