如何在没有完整源代码的情况下获取邮件内容?

标签: java javax.mail

我用javax读了一些邮件 然后我想保存邮件的内容。

例如,我读了一封简单内容为By: Test的邮件 现在我用.getContent()方法阅读内容:

Object body = message.getContent();
String content = ((body instanceof String) ? (String) body : "NO STRING CONTENT");

但问题是,By: Test的简单电子邮件内容由消息的整个Outlook源代码显示:

<html xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:w="urn:schemas-microsoft-com:office:word" xmlns:m="http://schemas.microsoft.com/office/2004/12/omml" xmlns="http://www.w3.org/TR/REC-html40">

那么如何在不获取整个邮件源代码的情况下读出邮件内容呢?

首先,我首先要提取<body>的{​​{1}}部分中的内容。之后,它取决于您的喜好,但您可以删除每个String - 标签,但请注意,任何格式化(换行!)代码都会消失,而您只能获得大量文本。

我只记得简单而好的方法。您可以只收取电子邮件的简单/文本部分。

String content = getPlainText((Part)message);

private String getPlainText(Part p) throws MessagingException, IOException {
    if (p.isMimeType("text/plain")) {
        return (String) p.getContent();
    } else if (p.isMimeType("multipart/*")) {
        Multipart mp = (Multipart) p.getContent();
        for (int i = 0; i < mp.getCount(); i++) {
            String s = getPlainText(mp.getBodyPart(i));
            if (s != null) return s;
        }
    }
    return null;
}
