php - 使用 PHP 将事件批量添加到 Google Calendar API

Question

我可以一次将 10,000 到 20,000 个事件添加到使用 PHP 的 Google 日历的最佳方法是什么？

如果我尝试单独添加它们，我会在每日最大值之前收到“超出限制”错误。

我也一直在考虑导入 ICAL/ICS 文件，但除了日历订阅之外，我似乎也找不到此功能。日历订阅很棒，但是当事件发生变化时，我需要在我的日历中进行几乎“实时”的更新，而且日历订阅何时更新还不清楚，这可能需要从 ICS 文件的初始更改开始最多一天的时间。

需要使用批处理请求。批处理请求由多个 API 调用组合成一个 HTTP 请求组成。批处理是一个已知的功能请求，并且正在积极处理。阅读以下关于它的文章：https ://developers.google.com/google-apps/calendar/batch

请参阅我的 multipleInsert 函数，例如：

class My_google_calendar
{
  ...

  /** Add single Event for Student */
  function addEvent($lesson, $instructor, $return_request = false, $enable_attendees = false)
  {
    $calendar = $this->getGoogleCalendar(); // get calendar service variable

    $lesson_from = date(DATE_RFC3339, $lesson->from);
    $lesson_to = date(DATE_RFC3339, $lesson->from + $lesson->duration); 

    $event = new Google_Service_Calendar_Event();
    $event->setSummary('Lesson with student: '$lesson->student_full_name);

    $start = new Google_Service_Calendar_EventDateTime();
    $start->setDateTime($lesson_from); 
    $start->setTimeZone($this->getGoogleCalendarTimeZone());
    $event->setStart($start);

    $end = new Google_Service_Calendar_EventDateTime();
    $end->setDateTime($lesson_to);
    $end->setTimeZone($this->getGoogleCalendarTimeZone());
    $event->setEnd($end);
    $event->setColorId(4);

    $description = "...";
    $event->setDescription($description);

    if (isset($student->email) && $enable_attendees) {
      $attendee1 = new Google_Service_Calendar_EventAttendee();
      $attendee1->setResponseStatus('needsAction');
      $attendee1->setEmail($student->email);
      $attendees = array($attendee1);
      $event->setAttendees($attendees);
    }

    $createdEvent = $this->calendar->events->insert($this->calendar_id, $event, array('fields' => 'id'));
    return $return_request ? $createdEvent : $createdEvent->getId();
  }

  /** Push group of events to the Calendar */
  function multipleInsert ($lessons, $instructor)
  {
    $this->use_batch = true;
    $this->client->setUseBatch($this->use_batch);
    $batch = new Google_Http_Batch($this->client);

    foreach($lessons as $time => $lesson) {      
        $lesson = array_shift($group['lessons']);
        $req = $this->addEvent($lesson, $instructor, true);
        $batch->add($req, $time);
      }
    }
    $results = $batch->execute();

    return $results;
  }

}
