java - 使用 java 电子邮件的日历事件

Question

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

<小时/>

示例:

发送到 G-Mail 地址时，接收者会像事件一样识别 .ics 文件，并在邮件正文中显示该事件的详细信息。

在雅虎，它标识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，并且不会被识别为事件。

<小时/>

我真的不知道如何让 Microsoft 邮件服务器识别该事件并显示详细信息和要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);

解决了!问题是，为 MultiPartEmail 创建 mimepart 放入 SimpleEmail 时效果很好。

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);
