JSON.CN让代码更轻
JSON 整理与类型生成可运行案例

设备列表：递归排序对象字段并保留数组顺序

递归按键名整理对象，便于人工检查。devices 的数组顺序不变；排序后的 JSON 文本不能直接当作通用签名规范或所有语言一致的 canonical JSON。

场景与操作说明

设备在线标记是采样时刻的状态，不能说明设备现在仍在线。此案例不扫描网络或连接任何设备。

battery 为演示百分比；网关的 100 只是样本值，不表示真实电源检测。

  1. 核对 设备列表 的字段层级，保留 deviceId 的字符串类型。
  2. 修改一项输入并运行，观察结果中的值或路径如何变化。
  3. 载入对照样本，复现下面的变化；恢复原例会替换当前输入。

对照样本

对照样本反转 devices 数组。字段排序不会把数组自动排回去，核对输出中的首条 deviceId。
