其他系统中的URLDecoder.decode(authInfo.toString(),"UTF-8")方法在HarmonyOS 中使用什么方法代替？

可以参考这个：

aboutToAppear(): void {
  let a: string = 'https://www.huawei.com?key1=中文&key2=value2'
  let b: string = 'https%3A%2F%2Fwww.huawei.com%3Fkey1%3D%E4%B8%AD%E6%96%87%26key2%3Dvalue2'
  console.log('-----------------------------------------------')
  console.log(encodeURIComponent(a))
  console.log(decodeURIComponent(b))
  console.log('-----------------------------------------------')
}
