Php 如何使用sendgrid发送日历邀请？

我正在尝试使用SendGrid发送日历邀请，当收到电子邮件时，邀请是一个.ics附件。我希望已显示邀请

以下是我当前添加日历的方式：

$email->addContent（“文本/日历”、$mimeMessage）

$mimeMessage设置为以下消息：

From: <from@someemail.com>
    To: <to@someemail.com>
        Subject: Program Calendar Event
        MIME-Version: 1.0
        Content-Type: text/calendar; method=REQUEST; charset="UTF-8"
        Message-ID: 2797a6bab44c7188e16e6e2408b02a4a.somedomain.com
        \r\nContent-Transfer-Encoding: 7bit

        BEGIN:VCALENDAR
        PRODID:-//Microsoft Corporation//Outlook 16.0 MIMEDIR//EN
        VERSION:2.0
        METHOD:REQUEST
        X-MS-OLK-FORCEINSPECTOROPEN:TRUE
        BEGIN:VEVENT
        LOCATION:123 Hill Top

        SEQUENCE:0
        SUMMARY:Program Calendar Event
        TRANSP:OPAQUE

        END:VEVENT
        END:VCALENDAR

谢谢大家!

看起来这是一张长期发行的票，请您试一下$附件->设置类型（“文本/日历；方法=请求”）；此外，我还可以通过标签（底部）发送日历事件，并通过gmail解析它们：$mail->addAttachment（新建\SendGrid\mail\Attachment（base64\u encode（'ICS\u CONTENT\u HERE'），“text/calendar；method=REQUEST”，“invite.ICS”","附件","附件");；非常感谢你！我将addContent改为include；方法=请求。于是它变成了：$email->addContent（“text/calendar；method=REQUEST”，$mimeMessage）；一切都在按预期进行。不用担心，只是为了证明有时候一个好的谷歌可以给你答案
