eluceo/ical 如何删除事件

Question

我正在使用 eluceo/ical 将应用程序中的事件添加到我的日历中。这很好用，我已经成功地将多个事件添加到我的日历中，但是如果我从应用程序中删除一个事件，它就会被日历保留。我怎样才能删除事件？

考虑以下创建日历的函数。

    public function createUserCalendar(): Component
    {
        // Get the shortname of the user
        $boom = explode( ' ', $this->name );
        $shortName = $boom[0];

        $events = [];
        $pending = $this->calendarPending()->get();

        foreach ( $pending as $day ) {
            $eventUid = 'ecl-' . $day->user_id . '-' . $day->id;
            $uniqueIdentifier = new UniqueIdentifier($eventUid);

            if ( $day->half_days === 1 ) {
                $summary = $shortName . ' Half day ' . $day->period;
            } else {
                $summary = $shortName . ' Full day';
            }
            $event = new Event( $uniqueIdentifier );

            $firstDay = new Date(\DateTimeImmutable::createFromFormat( 'Y-m-d', $day->date ));
            $lastDay = new Date(\DateTimeImmutable::createFromFormat( 'Y-m-d', $day->date));

            $occurrence = new MultiDay($firstDay, $lastDay);

            $event->setSummary( $summary )
                ->setStatus( EventStatus::CONFIRMED())
                ->setDescription( $day->description )
                ->setOccurrence( $occurrence );

            $events[] = $event;
        }

        $cancelled = $this->calendarCancelled()->get();

        foreach ( $cancelled as $day ) {
            $eventUid = 'ecl-' . $day->user_id . '-' . $day->id;
            $uniqueIdentifier = new UniqueIdentifier($eventUid);

            $event = new Event( $uniqueIdentifier );
            $firstDay = new Date(\DateTimeImmutable::createFromFormat( 'Y-m-d', $day->date ));
            $lastDay = new Date(\DateTimeImmutable::createFromFormat( 'Y-m-d', $day->date));

            $occurrence = new MultiDay($firstDay, $lastDay);

            $event->setOccurrence( $occurrence )->setStatus( EventStatus::CANCELLED());

            $events[] = $event;
        }

        // 2. Create Calendar domain entity
        $calendar = new Calendar( $events );

        // 3. Transform domain entity into an iCalendar component
        return (new CalendarFactory())->createCalendar( $calendar );
    }

如果我运行它并添加到日历中，我会看到所有日期都按预期正确添加。如果我随后取消活动并重新提交日历，它仍会显示该活动。那么如何将其从我的日历中删除和/或取消此活动？

谢谢

这是我生成的 ics 文件中包含取消事件的示例。正如下面评论中提到的，如果有帮助，我正在使用 Laravel9 和 php8.1，eluceo/ical 的文档可以在 https://ical.poerschke.nrw/docs
