网关新增子设备请求 功能介绍 网关主动新增其下接入的子设备，在平台上完成开户。网关与子设备关系，请查看网关与子设备。 Topic 上行: $oc/devices/{device_id}/sys/events/up 参数说明 字段名 必选/可选 类型 参数描述 object_device_id
使用HTTP/HTTPS转发 概述 订阅推送的示意图如下图所示： 物联网平台采用HTTPS协议向应用服务器进行消息推送时，物联网平台需要校验应用服务器的真实性，需要在物联网平台上加载CA证书，该证书由应用服务器侧提供（调测时可自行制作调测证书，商用时建议更换为商用证书，否则会带来安全风险）。
使用前必读 概述 MQTT是一种底层传输协议，一般用于网络通信，它提供有序有的、可靠的、双向字节流传输，支持设备到云端和云端到设备之间的消息传递，是基于发布/订阅模模式的“轻量级”通信协议。MQTT最大优点在于，可以以极少的代码和有限的带宽，为连接远程设备提供实时可靠的消息服务。
