我正在尝试解析电子邮件，但在使用邮件包时遇到了此类错误。是邮件包裹上的错误还是我应该自己处理？

短语中缺少单词:不支持字符集:“gb18030”

不支持的字符集:“koi8-r” 短语中缺少单词:不支持字符集:“ks_c_5601-1987”

我该如何修复它们？我想我应该使用 charset但我不确定如何 .这是电子邮件 header 的样子

编辑:

我尝试使用 charset打包但没有效果。我仍然在相同的消息上遇到相同的错误。

import "code.google.com/p/go-imap/go1/imap"
header := imap.AsBytes(rsp.MessageInfo().Attrs["RFC822.HEADER"])

            r, err := charset.NewReader("UTF-8", bytes.NewReader(header))
            if err != nil {
                log.Fatal(err)
            }
            fmt.Printf("new char is %v", r)

            msg, err := mail.ReadMessage(r)
            if err != nil {
                log.Fatal(err)
                return mgs, err
            }

            mg.From, err = msg.Header.AddressList("From")
            if err != nil {
                log.Errorf("NO FROM msg %s, err %v", header, err)
             return
              }

mail 包似乎只能解码rfc2047 但charset 包不支持这个

character set "rfc2047" not found

好像mahonia哪个可以解决这个问题？

最佳答案

我希望这对可能考虑使用 Go 处理电子邮件(即开发客户端应用程序)的人有所帮助。似乎标准的 Go 标准库对于电子邮件处理还不够成熟。它不处理多部分、不同的字符集等。在尝试了将近一天的不同 hack 和包之后，我决定放弃 go 代码并使用旧的优秀 JavaMail 解决方案。

关于email - "missing word in phrase: charset not supported", 使用邮件包时，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24902453/
