Parse email fields with Golang

问题

我正在尝试在Go中解析我的电子邮件,我需要帮助。

如何访问邮件的Content-type字段?

    cmd, _ = c.Fetch(set, "BODY[HEADER]", "BODY[1]")
    for cmd.InProgress() {
    for _, rsp = range cmd.Data {
        header := imap.AsBytes(rsp.MessageInfo().Attrs["BODY[HEADER]"])
    	body := imap.AsString(rsp.MessageInfo().Attrs["BODY[1]"])
        if msg, _ := mail.ReadMessage(bytes.NewReader(header)); msg != nil {

通过这样做,我可以访问正文和标题,但是当电子邮件包含附件时,使用BODY[1]会获取到所有的元数据,而不仅仅是纯文本。为了避免这种情况,我可以使用BODY[1.1],但是我需要根据Content-Type:[multipart/alternative]进行条件判断,而我无法访问到该字段。

英文:

I am trying to parse my emails in Go and I need help.

How to get access to Content-type field of mail?

    cmd, _ = c.Fetch(set, "BODY[HEADER]", "BODY[1]")
    for cmd.InProgress() {
    for _, rsp = range cmd.Data {
        header := imap.AsBytes(rsp.MessageInfo().Attrs["BODY[HEADER]"])
    	body := imap.AsString(rsp.MessageInfo().Attrs["BODY[1]"])
        if msg, _ := mail.ReadMessage(bytes.NewReader(header)); msg != nil {

with this I can gain access to Body and Header, but when email contain included file then with BODY[1] I have all meta-data, not only pure text. To avoid that I can use BODY[1.1], but I need condition by Content-Type:[multipart/alternative] and I can't gain access ot that field.

好的,以下是翻译好的内容:

好的,所以我自己找到了答案。但是无论如何,也许其他人对此感兴趣。你可以通过以下方式访问邮件的各个字段:

msg.Header.Get("Content-type")

而且你可以用任何标头部分的名称替换Content-type

fmt.println(msg)

可以知道它具有哪些字段名称。

英文:

Ok, so i figured it out by my self. But anyway, maybe someone else interested in that. You can have access to varios fields of mail by

msg.Header.Get("Content-type")

and instead of Content-type you can put any header part name.

fmt.println(msg)

to know what name fields it have
