HarmonyOS Object接口解析

对于不固定的key可以参考demo ，转成Map：

@Component
@Entry
struct Index {
  @State str: string = '{"id_1":{"xxx":"123"},"id_2":{"222":"333"}}'

  build() {
    Text('asadasd').onClick(() => {
      let jsonRecord: Map<string, Object> = new Map(Object.entries(JSON.parse(this.str)))
      jsonRecord.forEach((value, key) => {
        console.log("key:" + key)
        console.log("value:" + value)
      })
    })
  }
}
