通过 Symfony2（Swift 邮件程序）生成并发送 .ics 文件

Question

我正在尝试在 Symfony2 中生成日历事件 MS Outlook/Google Calendar，而电子邮件是使用 .ics 文件发送的，但我无法将事件添加到日历中。当我尝试打开文件时，它显示

Failed to import events: Unable to process your iCal/CSV file..

这就是我尝试生成 iCal 文件的方式

$message="
    BEGIN:VCALENDAR
    VERSION:2.0
    CALSCALE:GREGORIAN
    METHOD:REQUEST
    BEGIN:VEVENT
    DTSTART:".date('Ymd\THis', strtotime($meetingStartTime))."
    DTEND:".date('Ymd\THis', strtotime($meetingEndTime))."
    DTSTAMP:".date('Ymd\THis', strtotime($meetingStartTime))."
    ORGANIZER;CN=XYZ:mailto:do-not-reply@example.com
    UID:".rand(5, 1500)."
    ATTENDEE;PARTSTAT=NEEDS-ACTION;RSVP= TRUE;CN=Sample:emailaddress@testemail.com
    DESCRIPTION:".$this->getUser()->getName()." requested Phone/Video Meeting Request
    LOCATION: Phone/Video
    SEQUENCE:0
    STATUS:CONFIRMED
    SUMMARY:Meeting has been scheduled by ".$this->getUser()->getName()."
    TRANSP:OPAQUE
    END:VEVENT
    END:VCALENDAR";

$messageObject = \Swift_Message::newInstance();
$messageObject->setContentType("text/calendar");
$messageObject->setSubject("Your meeting has been booked")
              ->setFrom($this->container->getParameter('mailer_user'), "From Name")
              ->setTo($this->getUser()->getEmail())
              ->setBody(trim($message));
$this->get('mailer')->send($messageObject);

如果我能就我做错的事情获得一些帮助，我将不胜感激，这会导致 无法导入事件：无法处理您的 iCal/CSV 文件

Answer 1

您应该将 iCal 文件写入您的服务器（使用 Filesystem component or with native PHP functions like file_put_contents），然后将其作为附件发送：

use Symfony\Component\Filesystem\Filesystem;
use Symfony\Component\Filesystem\Exception\IOExceptionInterface;

$fs = new Filesystem();

//temporary folder, it has to be writable
$tmpFolder = '/tmp/';

//the name of your file to attach
$fileName = 'meeting.ics';

$icsContent = "
    BEGIN:VCALENDAR
    VERSION:2.0
    CALSCALE:GREGORIAN
    METHOD:REQUEST
    BEGIN:VEVENT
    DTSTART:".date('Ymd\THis', strtotime($meetingStartTime))."
    DTEND:".date('Ymd\THis', strtotime($meetingEndTime))."
    DTSTAMP:".date('Ymd\THis', strtotime($meetingStartTime))."
    ORGANIZER;CN=XYZ:mailto:do-not-reply@example.com
    UID:".rand(5, 1500)."
    ATTENDEE;PARTSTAT=NEEDS-ACTION;RSVP= TRUE;CN=Sample:emailaddress@testemail.com
    DESCRIPTION:".$this->getUser()->getName()." requested Phone/Video Meeting Request
    LOCATION: Phone/Video
    SEQUENCE:0
    STATUS:CONFIRMED
    SUMMARY:Meeting has been scheduled by ".$this->getUser()->getName()."
    TRANSP:OPAQUE
    END:VEVENT
    END:VCALENDAR"
;

//creation of the file on the server
$icfFile = $fs->dumpFile($tmpFolder.$fileName, $icsContent);

//message to include as body to your mail
$body = 'Hello...';

$messageObject = \Swift_Message::newInstance();
$messageObject->setSubject("Your meeting has been booked")
              ->setFrom($this->container->getParameter('mailer_user'), "From Name")
              ->setTo($this->getUser()->getEmail())
              ->setBody($body)
              ->attach(Swift_Attachment::fromPath($tmpFolder.$fileName))
;
$this->get('mailer')->send($messageObject);

//remove the created file
$fs->remove(array('file', $tmpFolder, $fileName));

如果您想要创建 OOP，可以使用包：https://github.com/markuspoerschke/iCal

可以使用 composer 完成安装，SF 用户无需在 appKernel 中添加包。
