如何使用hono批量发送遥测数据

Question

我能够使用 hono 适配器通过 HTTP 发送遥测数据，我使用的是 cpp 方法。

当我一一发送每个功能时，我看到它反映在 DITTO 上 为单个特征生成的 jsonData 示例：

{"topic": "org.tip/dev1/things/twin/commands/modify","headers": {},"path": "/features/sensor1/properties/value","value": 1}

问题是我添加了一堆功能（传感器），每次我想发送遥测数据时，我都会在短时间内发送多个 HTTP 调用。所以现在我想将它们分组。但它不起作用。这是生成的jsonData：

{"topic": "org.tip/dev1/things/twin/commands/modify","headers": {},"data": 
 {path": "/features/sensor1/properties/value","value": 1},
 {path": "/features/sensor2/properties/value","value": 23},
 {path": "/features/sensor3/properties/value","value": 32},
 {path": "/features/sensor4/properties/value","value": 4},
 {path": "/features/sensor5/properties/value","value": 13},
 {path": "/features/sensor6/properties/value","value": 17}}

我收到

HTTP Status Code: 202

，所以它被接受，但我认为 json 格式是错误的。有没有任何参考或有人知道应该如何生成json
