最近有一个我的项目须要对接海康监控，这里我写了一个demo，不便咱们来调用海康监控的相干接口
海康监控接口文档：https://open.hikvision.com/do...
海康监控demo：

应用海康监控demo简略示例
分页获取监控点资源
$data = [ 'pageNo' => 1,//指标页码,范畴 (0 , ~ ) 'pageSize' => 1000,//每页记录数,范畴 (0 , 1000) ]; $apiUrl = '/artemis/api/resource/v1/cameras'; $artemis = new Artemis($apiUrl, 'POST', $data); $data=$artemis->apiInterface();如上既能够获取到监控点资源，其余相干接口调用形式参照如上即可
