如何在Go中解码邮件正文

Question

I'm working on an email client and part of this I need to decode the email body. I'm using the IMAP package to fetch the messages but there is no "decode" method. I also checked the net/mail package with no luck either. Only the headers seem to have a parser. Is there any lib that I can use?

You can check if a project like artagnon/ibex, which uses the go-imap package, does provide that feature.
See for instance its artagnon/ibex/imap.go#L288-L301 test.

var body []byte
cmd, err = imap.Wait(c.UIDFetch(set, "BODY.PEEK[]"))
if (err != nil) {
    fmt.Println(err.Error())
    return nil
}
body = imap.AsBytes(cmd.Data[0].MessageInfo().Attrs["BODY[]"])
cmd.Data = nil

bytestring, err := json.Marshal(MessageDetail{string(body)})
if (err != nil) {
    fmt.Println(err.Error())
    return nil
}
return bytestring
