用PHP一次向Google日历添加10000到20000个事件的最佳方式是什么？
如果我尝试单独添加它们，我会在每日最大之前出现"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，我似乎也找不到其他功能。日历订阅很好，但当事件发生更改时，我需要在日历中进行几乎"实时"的更新，而且还不清楚日历订阅何时更新，这可能需要从ICS文件的初始更改开始一天的时间。
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，目前正在积极处理。请阅读以下关于它的文章：https://developers.google.com/google-apps/calendar/batch
例如，请参阅我的multipleInsert函数：
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;
}
}
