哈喽！今天心血来潮给大家带来了《使用net/mail库来解析电子邮件》，想必大家应该对Golang都不陌生吧，那么阅读本文就都不会很困难，以下内容主要涉及到，若是你正在学习Golang，千万别错过这篇文章~希望能帮助到你！
问题内容
我目前正在 golang 中使用 net/mail 解析电子邮件。
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))
}
这对于纯文本电子邮件来说效果很好。但是，当我使用包含 html 的 apple mail 应用程序发送电子邮件时，返回了以下正文：
--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
