JSON 整理与类型生成可运行案例

文件上传结果：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。files 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

上传结果中的文件名不保证实际文件格式，uploaded 字段也不替代服务端存储校验。示例只处理元数据，不读取或上传真实文件。

bytes 以字节计，换算 KB 前先确认平台采用 1000 还是 1024。

  1. 核对 文件上传结果 的字段层级，保留 fileId 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 files 数组。字段排序不会把数组自动排回去，核对输出中的首条 fileId。
