HarmonyOS HashMap使用JSON.stringify()打印出来为{}

class MethodCollector {
  methodName: string = "";
  args: HashMap<string, string> = new HashMap()
  returnValue: object = new Object();
}

for (let i = 0; i < arrayList.length; i++) {
  let m: MethodCollector = arrayList[i];
  let c = m.args;
  c.forEach((value?: string, key?: string) => {
    console.log('zztest', "value:" + value, "key:" + key);
    console.log('zztest', JSON.stringify(arrayList));
    hilog.info(0x0001, "zztest", "print object: %{public}s", JSON.stringify(arrayList));
  });
}
