我正在尝试使用 iCal 通过电子邮件发送邀请。我的电子邮件发送工作正常，但我没有正确收到 iCal 附件。以下是我处理电子邮件发送的 php 函数。

    function sendIcalEmail($firstname,$lastname,$email,$meeting_date,$meeting_name,$meeting_duration) {

        $from_name = "Sampath";
        $from_address = "my email";
        $subject = "Meeting Booking"; //Doubles as email subject and meeting subject in calendar
        $meeting_description = "Here is a brief description of my meeting.";
        $meeting_location = "My Office"; //Where will your meeting take place


        //Convert MYSQL datetime and construct iCal start, end and issue dates
        $meetingstamp = strtotime($meeting_date . " UTC");    
        $dtstart= gmdate("Ymd\THis\Z",$meetingstamp);
        $dtend= gmdate("Ymd\THis\Z",$meetingstamp+$meeting_duration);
        $todaystamp = gmdate("Ymd\THis\Z");

        //Create unique identifier
        $cal_uid = date('Ymd').'T'.date('His')."-".rand()."@example.com";

        //Create Mime Boundry
        $mime_boundary = "----Meeting Booking----".md5(time());

        //Create Email Headers
        $headers = "From: ".$from_name." <".$from_address.">\n";
        $headers .= "Reply-To: ".$from_name." <".$from_address.">\n";

        $headers .= "MIME-Version: 1.0\n";
        $headers .= "Content-Type: multipart/alternative; boundary=\"$mime_boundary\"\n";
        $headers .= "Content-class: urn:content-classes:calendarmessage\n";

        //Create Email Body (HTML)
        $message .= "--$mime_boundary\n";
        $message .= "Content-Type: text/html; charset=UTF-8\n";
        $message .= "Content-Transfer-Encoding: 8bit\n\n";

        $message .= "<html>\n";
        $message .= "<body>\n";
        $message .= '<p>Dear '.$firstname.' '.$lastname.',</p>';
        $message .= '<p>Here is my HTML Email / Used for Meeting Description</p>';    
        $message .= "</body>\n";
        $message .= "</html>\n";
        $message .= "--$mime_boundary\n";

        //Create ICAL Content (Google rfc 2445 for details and examples of usage) 
        $ical =    "BEGIN:VCALENDAR\n".
           "PRODID:-//Microsoft Corporation//Outlook 11.0 MIMEDIR//EN\n".
           "VERSION:2.0\n".

           "DTSTART:".$dtstart."\n".

           "PRIORITY:5\n".
           "CLASS:PUBLIC\n".
           "END:VEVENT\n".
           "END:VCALENDAR";   

        $message .= 'Content-Type: text/calendar;name="meeting.ics";method=REQUEST;charset=utf-8\n';
        $message .= 'Content-Type: text/calendar;name="meeting.ics";method=REQUEST\n';
        $message .= "Content-Transfer-Encoding: 8bit\n\n";
        $message .= $ical;            

        //SEND MAIL

        require_once "./swiftmailer/swift_required.php";

        $transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl")
            ->setUsername('my email')
            ->setPassword('password');

        $mailer = Swift_Mailer::newInstance($transport);

        $sendMessage = Swift_Message::newInstance('Meeting Invitation')
           ->setFrom(array($from_address => 'Sampath B. Herath'))
           ->setTo(array($email))
           ->setBody($message);

        $result = $mailer->send($sendMessage);

        if($result) {
            return true;
        } else {
            return false;
        }   
    }

以下是我在结果电子邮件中可以看到的内容。

我已经完成了我的任务，以下是我的完成方式。

    $meeting_date = "2013-08-20 13:00:00"; //mysql format

    $result = sendIcalEmail($firstname,$lastname,$email,$meeting_date,$meeting_name,$meeting_duration);

    $mail_sent = @mail( $email, $subject, $message, $headers );

    if($mail_sent)     {
        return true;
    } else {
        return false;
    }
}

我使用sendmail服务器来测试电子邮件发送。

我参考了这篇文章来完成任务。

首先，您输出 icalendar bodypart 的内容类型两次。

然后，此内容类型提及方法=REQUEST，而实际 iCalendar 包含 METHOD=PUBLISH。

我怀疑 gmail 只理解 METHOD=REQUEST 在这种情况下，您需要查看此类 iTIP 消息的强制属性。最明显的一个是缺少 ATTENDEE 属性。有关完整列表，请参阅https://www.rfc-editor.org/rfc/rfc5546#section-3.2.2。
