HarmonyOS JSON.parse 返回值是Object 类型，但是怎么遍历Object类型属性呢

遍历json数据，可以参考下面示例

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]);
}
