HarmonyOS 使用JSON.parse将一个字符串转换成JSON后如何遍历Json中的Key value

遍历Json数据可参考下面示例:

const jsonStr = '{"name": "Alice", "age": 30}';
let jsonObj: Object = JSON.parse(jsonStr);

let keyArr: string[] = Object.keys(jsonObj);
let valueArr: string[] = Object.values(jsonObj);
let entryArr: [string, string][] = Object.entries(jsonObj)
for (let i = 0; i < entryArr.length; i++) {
  console.log(keyArr[i] + ":" + valueArr[i]);
}
