WebSocket 是一种网络传输协定，可在单个 TCP 连贯上进行全双工通信，位于 OSI 模型的应用层。WebSocket 协定在 2011 年由 IETF 标准化为 RFC 6455，后由 RFC 7936 补充标准。
WebSocket 使得客户端和服务器之间的数据交换变得更加简略，容许服务端被动向客户端推送数据。在 WebSocket API 中，浏览器和服务器只须要实现一次握手，两者之间就能够创立持久性的连贯，并进行双向数据传输。本文次要跟大家分享一下智汀家庭云的WebSocket API 音讯定义。
1.音讯定义
通常，一个 WebSocket 音讯格局如下：
{ "id": 1, "domain": "", "service": "", "service_data": { "device_id": 1 }}·id: 音讯ID，必填，服务端会返回对应 ID 的后果
·domain: plugin或者插件id
- 设施相干命令
2.1插件设施状态变更
{ "type": "attribute_change", "identity": "2762071932", "instance_id": 2, "attr": { "attribute": "power", "val": "on", "val_type": "string" }}2.2发现设施
申请：Request
{ "id": 1, "service": "discover"}响应：Response
{ "id": 1, "type": "", "result": { "device": { "name": "zhiting_M1", "identity": "hijklmn", "model": "M1", "manufacturer": "zhiting", "plugin_id": "demo" } }, "success": true}2.3获取设施属性
申请：Request
{ "id": 1, "domain": "zhiting", "service": "get_attributes", "identity": "2762071932"}响应：Response
{ "id": 1, "result": { "identity": "2762071932", "device": { "name": "", "identity": "2762071932", "instances": [ { "type": "light_bulb", "instance_id": 0, "attrs": [ { "attribute": "power", "val": "on", "val_type": "string" }, { "attribute": "brightness", "val": 55, "val_type": "int" }, { "attribute": "color_temp", "val": 3500, "val_type": "int" } ] } ] } }, "success": true}2.4 设置设施属性
申请：Request
{ "id": 1, "domain": "zhiting", "service": "set_attributes", "identity": "2762071932", "service_data": { "attributes": [ { "instance_id": 1, "attribute": "power", "val": "on" } ] }}响应：Response
{ "id": 1, "type": "response", "success": true, "error": "error"}3.装置插件
{ "id": 1, "domain": "plugin", "service": "install", "service_data": { "plugin_id": "plugin_id" }}{ "id": 1, "success": true}以上，感激大家观看，感兴趣的能够在评论区给小编留言哦。
