使用sabre/vobject库，我正在创建一个像这样的 ics 文件：

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Sabre//Sabre VObject 4.1.2//EN
CALSCALE:GREGORIAN
BEGIN:VEVENT
UID:sabre-vobject-d4b1ccb3-2197-4ee4-aab8-7bc2516adbf8
DTSTAMP:20170123T182612Z
SUMMARY:testev2
DESCRIPTION:
DTSTART;TZID=Europe/Athens:20170214T090000
DTEND;TZID=Europe/Athens:20170215T170000
LOCATION:
ORGANIZER;CN=Organizer Name:mailto:organizer@example.com
ATTENDEE;CN=Test User:MAILTO:test.user@somewhere.com
END:VEVENT
END:VCALENDAR

然后使用phpmailer，我将生成的文件附加到电子邮件中，并将其发送给参与活动的用户。使用 Thunderbird（带有 Lightning 扩展程序 - 默认情况下处于打开状态）的用户会收到以下格式的电子邮件：

在此处输入图像描述

正如您在图片中看到的，ics 文件被解析并呈现在电子邮件底部的表格中。但是表头（以红色标记的）没有显示正确的信息。测试用户从未确认过他/她的存在，如果他/她确认过，ics 文件不会提供任何有关它的信息。

我的ics文件格式错误吗？

它是雷鸟/闪电的已知错误吗？

您应该使 ics 附件的 Content-Type 类似于：

Content-Type: text/calendar; charset="utf-8"; method=REQUEST

method选项是神奇的词。我不完全确定这是否有效，但至少更接近规范。如果它不起作用，我很乐意更新我的答案。
