欢迎使用 Google Home 开发者中心,您可以在这里学习有关如何开发智能家居 Action 的新平台。注意:你将继续在 Actions 控制台中构建操作。

识别并同步

使用集合让一切井井有条 根据您的偏好保存内容并对其进行分类。

创建智能家居 Action 后,下一步是在执行方式中添加功能,以便处理智能家居 intent 并返回 Google 助理可识别的响应。

识别用户

Google 助理会使用 OAuth 2.0 服务器在 Authorization 标头中提供的访问令牌向智能家居 Action 的执行方式发出请求。

POST /fulfillment HTTP/1.1
Host: smarthome.example.com
Content-Type: application/json
Authorization: Bearer ACCESS_TOKEN

在响应任何请求之前,你的执行方式逻辑应验证此令牌凭据是否有效并确定关联的用户帐号。如果访问令牌无效,你的执行方式应返回 HTTP 401 Unauthorized 错误。

列出设备及其功能

Google 助理会向你的执行方式发送 action.devices.SYNC intent,以请求与指定用户及其功能相关联的设备列表。你的执行方式必须在 SYNC 响应的 agentUserId 字段中返回每个用户的唯一 ID。此 ID 必须是表示你的云服务用户的不可变值。我们建议你不要根据用户可更改的设置提供电子邮件地址或其他属性。

SYNC 响应的 devices 字段包含用户授权 Google 助理访问的所有设备、设备支持的类型和特征,以及为特定设备配置特征行为所需的属性。

SYNC intent 会在帐号关联期间或在用户手动重新同步其设备时触发。如果用户的设备列表、支持的特征或属性值发生变化,请使用请求同步 触发新的 SYNC intent,并向 Google 报告更新内容。
