使用 php 发送 Outlook 会议邀请不起作用

Question

我正在使用ical_library生成会议邀请，它正在生成一个代码：

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Sabre//Sabre VObject 4.1.0//EN
CALSCALE:GREGORIAN
BEGIN:VEVENT
UID:sabre-vobject-4b0105a1-bac5-4068-bd65-b4581d3497c4
DTSTAMP:20160602T081647Z
SUMMARY:Training Schedule Invitation
DTSTART:2016-06-03 09:00:00
DTEND:2016-06-03 10:00:00
LOCATION:Bangalore
ATTENDEE:[e-mail]
END:VEVENT
END:VCALENDAR

但是当我将此代码作为邮件内容发送时，它不会转换为邀请。

将显示相同的代码。我正在使用codeigniter电子邮件库来发送电子邮件。

Answer 2

当我在线验证 ICS 数据时，它返回以下错误：

---

错误

无效的 DTSTART 值，必须是行 # 5 附近的日期或日期时间值

参考：RFC 5545 3.3.5。日期-时间

无效的 DTEND 值，必须是行 # 5 附近的日期或日期时间值

参考：RFC 5545 3.3.5。日期-时间

我也遇到了这个问题，最终将ics文件作为代码点火器中的附件发送：

$this->email->attach($ics_data_as_string, 'attachment', $name_for_ics_file_in_email, 'text/calendar');

希望这有所帮助。
