带有 java 电子邮件的日历事件

Question

我制作了一个 .ics 文件从 org.apache.commons.mail.MultiPartEmail 发送，但每个电子邮件服务器的结果都不同；

示例：

发送到 G-Mail 地址时，收件人将 .ics 文件识别为事件，并在邮件正文中显示事件的详细信息。

在雅虎，它识别事件但不显示详细信息。

在 Microsoft 邮件服务器（hotmail、outlook）中，.ics 文件在邮件正文中显示为纯文本，无法被识别为事件。

我真的不知道如何让 Microsoft 邮件服务器识别事件并显示详细信息和添加到日历中的按钮。

这是.ics代码：

这是代码：

MimeMultipart mmp = new MimeMultipart("mixed");

    MimeMultipart mmpa = new MimeMultipart("alternative");

    MimeBodyPart plainPart = new MimeBodyPart();
    plainPart.setHeader("Content-Type", "text/plain; charset=UTF-8; format=flowed; delsp=yes");
    plainPart.setHeader("Content-Transfer-Encoding", "base64");
    ByteArrayDataSource dsPlain = new ByteArrayDataSource("","text/plain;method=REQUEST");
    DataHandler dhPlain = new DataHandler(dsPlain);
    plainPart.setDataHandler(dhPlain);
    mmpa.addBodyPart(plainPart);

    MimeBodyPart calendarPart = new MimeBodyPart();
    calendarPart.setHeader("Content-Type", "text/calendar; charset=UTF-8; method=REQUEST");
    calendarPart.setHeader("Content-Transfer-Encoding", "7bit");
    ByteArrayDataSource dsCalendario = new ByteArrayDataSource(str,"text/calendar;method=REQUEST");
    DataHandler dhCalendario = new DataHandler(dsCalendario);
    calendarPart.setDataHandler(dhCalendario);
    mmpa.addBodyPart(calendarPart);

    MimeBodyPart htmlAndTextBodyPart = new MimeBodyPart();
    htmlAndTextBodyPart.setContent(mmpa);
    mmp.addBodyPart(htmlAndTextBodyPart);


    email.addPart(mmp);

已解决！问题是当放入 SimpleEmail 时，为 MultiPartEmail 创建 mimepart 工作得很好。

SimpleEmail email = new SimpleEmail();

MimeMultipart mmpa = new MimeMultipart("alternative");

//Calendar
MimeBodyPart calendarPart = new MimeBodyPart();
calendarPart.setHeader("Content-Type", "text/calendar; charset=UTF-8; method=REQUEST");
ByteArrayDataSource dsCalendario = new ByteArrayDataSource(str,"text/calendar;method=REQUEST");
DataHandler dhCalendario = new DataHandler(dsCalendario);
calendarPart.setDataHandler(dhCalendario);
mmpa.addBodyPart(calendarPart);

email.setContent(mmpa);
