我在使用icalendar时遇到了这个问题，当发送到gmail,yahoo, aoutlook.com时，它不显示附件和确认按钮。它以前没有HTML消息和多部分/混合头。现在当我收到电子邮件时，它只显示日历的文本，它不能识别它。内容类型:multipart/混合;边界= " 982 f8d486c3cbed0e28b314e7a433c3d "

你的第二个body部分有2个content-type header:
Content-Type: application/ics; name="Rv-invite.ics"
Content-Disposition: attachment; filename="Rv-invite.ics"
Content-Transfer-Encoding: base64
和
Content-Type: text/html; charset=UTF-8

看起来有些标题也属于顶层，而不是正文部分:
