使用 net/mail 解析电子邮件

Question content

I am currently using net/mail in golang to parse emails.

import (
  "net/mail"
  "io"
  "strings"
)

func main() {
  email := "some email received"

  reader := strings.newreader(emailinput)
  msg, err := mail.readmessage(inputreader)
  check(err)

  body, err := io.readall(msg.body)
  check(err)

  fmt.println(string(body))
}

This works well for plain text emails. However, when I send an email using the apple mail app that contains html, the following body is returned:

--Apple-Mail=3D_4A1E75FB-9514-439D-B922-8526851CA743
Content-Transfer-Encoding: 7bit
Content-Type: text/plain;
    charset=3Dus-ascii

fn main() {
  println!("Hello world!");
}


--Apple-Mail=3D_4A1E75FB-9514-439D-B922-8526851CA743
Content-Transfer-Encoding: 7bit
Content-Type: text/html;
    charset=3Dus-ascii

<html><head><meta http-equiv=3D"Content-Type" content=3D"text/html; charset=
=3Dus-ascii"></head><body style=3D"word-wrap: break-word; -webkit-nbsp-mode=
