Question

当附件在Microsoft Outlook中保存的消息时，它会保存为“.msg”文件，其中包含电子邮件的所有内容以及附件文件。我想提取电子邮件正文的文本内容及其附件。 Apache Tika是否支持'.msg'文件？如果没有其他想法？

Answer 1

如果查看list of mail formats supported by Apache Tika 1.9（当前是最新版本），您会看到Outlook MSG文件被列为受支持。

从Apache POI project's test files获取一个简单的MSG文件示例，并使用Tika App独立jar来简化测试，我们可以轻松获取内容和元数据：

This is a test message.

元数据，包括发件人，收件人，日期等，文字，所有你想要的！

或者，如果您有特殊需求/要求并希望完全控制，则可以使用基础Apache POI HSMF library来解析MSG文件，查看HSMF unit tests的使用示例

Tika支持msg files

您可以使用apache POI周围有一些示例one

样品：

  public static void main(String[] args) throws Exception{
    MsgParser msgp = new MsgParser();
    Message msg = msgp.parseMsg("c:/temp/test2.msg");

    String fromEmail = msg.getFromEmail();
    String fromName = msg.getFromName();
    String subject = msg.getSubject();
    String body = msg.getBodyText();

    System.out.println("From :" + fromName + " <" + fromEmail + ">");
    System.out.println("Subject :" + subject);
    System.out.println("");
    System.out.println(body);
    System.out.println("");

    List atts = msg.getAttachments();
    for (Attachment att : atts) {
      if (att instanceof FileAttachment) {
        FileAttachment file = (FileAttachment) att;
        System.out.println("Attachment : " + file.getFilename());
        // you get the actual attachment with
        // byte date[] = file.getData();
      }
    }
  }
