使用非ASCII名称将javax.mail.internet.MimeMessage发送给收件人吗？

treat your mods well 发表于 Java

好好对待你的mods：

我正在编写一段Java代码，该代码需要将邮件发送给具有非ASCII名称的用户。我已经弄清楚了如何对正文，主题行和通用标头使用UTF-8，但是我仍然停留在收件人上。

这是我在“收件人：”字段中想要的："ウィキペディアにようこそ" <[email protected]>。（针对我们今天的目的）这存在于名为的字符串中recip。

msg.addRecipients(MimeMessage.RecipientType.TO, recip) 给 "忙俾ェ▎S]" <[email protected]>
msg.addHeader("To", MimeUtility.encodeText(recip, "utf-8", "B")) 抛出 AddressException: Local address contains control or whitespace in string ``=?utf-8?B?IuOCpuOCo+OCreODmuODh+OCo+OCouOBq+OCiOOBhuOBk+OBnSIgPA==?= =?utf-8?B?Zm9vQGV4YW1wbGUuY29tPg==?=''

我该怎么发送此消息？

这是我处理其他组件的方式：

正文HTML： msg.setText(body, "UTF-8", "html");
标头： msg.addHeader(name, MimeUtility.encodeText(value, "utf-8", "B"));
学科： msg.setSubject(subject, "utf-8");

好好对待你的mods：

gh，它是通过一个愚蠢的骇客获得的：

/**
 * Parses addresses and re-encodes them in a way that won't cause {@link MimeMessage}
 * to freak out. This appears to be the only robust way of sending mail to recipients
 * with non-ASCII names. 
 * 
 * @param addresses  The usual comma-delimited list of email addresses.
 */
InternetAddress[] unicodifyAddresses(String addresses) throws AddressException {
    InternetAddress[] recips = InternetAddress.parse(addresses, false);
    for(int i=0; i<recips.length; i++) {
        try {
            recips[i] = new InternetAddress(recips[i].getAddress(), recips[i].getPersonal(), "utf-8");
        } catch(UnsupportedEncodingException uee) {
            throw new RuntimeException("utf-8 not valid encoding?", uee);
        }
    }
    return recips;
}

我希望这对某人有用。
