1. 设备状态主动推送

1.1. 流程说明

1. 在开放平台-智能家居-品牌管理-权限管理中开启上报设备状态开关。此时会得到平台分配的 clientId，clientSecret。
2. 在用户绑定此品牌时，在 rokid 开放平台智能家居品牌中配置的 endpoint 地址会收到一个AcceptGrant（具体描述见下文）指令，payload 中会包含 code 和用户在 rokid 的用户 id。
3. 厂商需要按照 OAuth2.0 的标准，携带上一步得到的 code，去 rokid OAuth2.0 token endpoint（地址: https://oauth-service.rokid.com/oauth/token）换取 access_token,refresh_token (具体描述见 https://tools.ietf.org/html/rfc6749#section-4.1.3)，然后按照下文协议描述正确响应AcceptGrant指令。
4. 厂商需在 token 过期时间以内主动刷新 token，保证 token 永不过期。
5. 厂商状态上报地址为 https://homebase-openapi.rokid.com/async/events

1.2. AcceptGrant 指令

• AcceptGrant

Rokid 向厂商发送AcceptGrant指令 (POST)

{
  "header": {
    "namespace": "Rokid.Authorization",
    "name": "AcceptGrant",
    "messageId": "5f8a426e-01e4-4cc9-8b79-65f8bd0fd8a4",
    "authorization": {
      "type": "BearerToken",
      "token": "access-token"
    },
    "payloadVersion": "v1"
  },
  "payload": {
    "grant": {
      "type": "OAuth2.AuthorizationCode",
      "code": "VGhpcyBpcyBhbiBhdXRob3JpemF0aW9uIGNvZGUuIDotKQ==",
      "userId": "12e213e345" //用户在rokid的用户id
    }
  }
}

• AcceptGrant.Response

权限获取成功后的正常返回

{
  "header": {
    "messageId": "abc-123-def-456",
    "namespace": "Rokid.Authorization",
    "name": "AcceptGrantResponse",
    "payloadVersion": "v1"
  },
  "payload": {}
}

如果失败，请按协议返回标准错误。

1.3. 推送消息类型

消息推送地址 POST https://homebase-openapi.rokid.com/async/events

当设备状态变化时，支持以下三种异步消息

1.4. Q&A

1.4.1. 如何开启此功能？

rokid 开放平台-智能家居-品牌管理-基础信息-权限管理-上报设备状态 打开。

1.4.2. 老用户如何迁移？

开关打开后，新绑定的用户自动拥有此功能；老用户需被告知重新绑定即可。

1.4.3. 当 access_token 失效并且 refresh 不成功时，该如何做？

为了保证良好的用户体验，我们需要一种机制让用户在状态上报链路失效时感知到。 为此我们提供了接口 https://homebase-openapi.rokid.com/report/failed (WIP 暂未完成) 当 access_token 失效并且不能成功刷新时，厂商应当将AcceptGrant指令带来的 userId，和自身 clientId 上报告知 rokid，rokid 会选择合适的方式通知用户（包括在 rokid App 内发送通知、短信通知等）。 上报请求举例：

POST /report/failed HTTP/1.1
Host: homebase-openapi.rokid.com
Content-Type: application/x-www-form-urlencoded

userId=2erf3gfeg3gt&clientId=SplxlOBeZQQYbYS6WxSbIA&sign=3sdfsfesdfeffffffffff

签名算法：Hmac, sha256 代码举例（nodejs）

const crypto = require("crypto");

function sign(data, secret) {
  const hmac = crypto.createHmac("sha256", secret);
  hmac.update(data);
  return hmac.digest("hex");
}

sign(
  "userId=2erf3gfeg3gt&clientId=SplxlOBeZQQYbYS6WxSbIA",
  "the_client_secret"
);
