HarmonyOS 有没有将字符串用url编码的api，或者三方库

请参考使用encodeURIComponent()和decodeURIComponent()。参考代码：

aboutToAppear(): void {
  let a: string = 'xxxxx'
  let b: string = 'xxxx'
  console.log('test-----------------------------------------------')
  console.log('test: ' + encodeURIComponent(a))
  console.log('test: ' + decodeURIComponent(b))
  console.log('test-----------------------------------------------')
}
