HarmonyOS url里的字符串怎么解析

请参考：

import Url from '@ohos.url'
@Entry
@Component
struct ButtonExample {
  build() {
    Column(){
      Button('点击')
        .onClick(()=>{
          let urlParams = "mk:///WebView?fullscreen=true&opaque=true&progress_hidden=true&busy_hidden=false&url=https%3A%2F%2Fintouch-coach-app.uat.mybiz-eks-chn.mkiapp.com%2Femployee"
          let decodeURL = decodeURIComponent(urlParams);
          let paramsObject = new Url.URLParams(decodeURL);
          console.log('progress_hidden：'+ paramsObject.get("progress_hidden"))
          console.log('busy_hidden：'+ paramsObject.get("busy_hidden"))
          console.log('url：'+ paramsObject .get("url"))
        })
    }
  }
}
