调用 Office365 API 同步事件，节流

Question

我正在尝试将一些事件从 Outlook 同步到我的本地数据库，我调用 API 如下：

$url = 'https://outlook.office365.com/api/v2.0/users/' . $this->user . '/CalendarView/'
    . '?startDateTime=' . $start_datetime
    . '&endDateTime=' . $end_datetime

这为我提供了两个特定日期之间来自 Outlook 的所有事件。

然后我使用下面的代码保存所有这些事件。它的问题是它 returns 一次只有 10 个事件。

$http = new \Http_Curl();
        $http->set_headers( $this->get_headers() );
        $response = $http->get( $url );

        $data = array();

        $continue = true;
        while ( $continue ) {
            if ( isset($response->value) ) {
                $arr = array();

                foreach ( $response->value as $event ) {
                    $arr[] = $event;
                }

                $data = array_merge( $data, $arr );
            }

            $property = '@odata.nextLink';
            if ( isset( $response->$property ) ) {
                $url = $response->$property;
                $response = $http->get( $url );
            } else {
                $continue = false;
            }
        }

        unset( $http );

        return $data;

然后我尝试像下面那样调用 API，将 top 参数设置为 10，但我最终得到了许多空事件。

$url = 'https://outlook.office365.com/api/v2.0/users/' . $this->user . '/CalendarView/'
    . '?startDateTime=' . $start_datetime
    . '&endDateTime=' . $end_datetime
     .'&top=100'

我尽量避免每分钟拨打超过 60 次电话。有什么方法可以先获取两个日期之间的事件数，然后再检索所有事件，所以top参数实际上应该是事件总数。

正确的查询参数是 $top 而不是 top。注意那里的$。

5.1.5 System Query Options $top and $skip The $top system query option requests the number of items in the queried collection to be included in the result. The $skip query option requests the number of items in the queried collection that are to be skipped and not included in the result. A client can request a particular page of items by combining $top and $skip. The semantics of $top and $skip are covered in the [OData-Protocol] document. The [OData-ABNF] top and skip syntax rules define the formal grammar of the $top and $skip query options respectively.
