列出对象字段 / json.keys

使用场景 / Purpose

Json: keys. 本技能对提供的参数执行计算，输入输出契约如下。文档例子来自已实现函数的固定验收样例；网页本身不执行代码。

字段	类型	要求	约束与说明
`data`	"object"	必填 Required	`{"properties": {}, "required": [], "additionalProperties": {"type": ["object", "array", "string", "number", "boolean", "null"], "maxProperties": 1000, "maxItems": 1000, "maxLength": 60000, "minimum": -1e+100, "maximum": 1e+100}, "maxProperties": 1000}`

输入例子 / Example input

{
  "data": {
    "b": 2,
    "a": 1
  }
}

预期输出 / Expected output
