HarmonyOS web页面如何使用deeplink跳转到系统地图

使用webView onLoadIntercept拦截前端请求，目的是获取拉起应用的url，或者使用其他方式例如javaScriptProxy，获取url，再在应用侧通过context.startAbility(want)拉起系统地图

import { common, Want } from '@kit.AbilityKit';

@Entry
@Component
struct StartAblity {
  @State message: string = 'Hello World';

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(()=>{
            let context = getContext(this) as common.UIAbilityContext;
            let petalMapWant: Want = {
              bundleName: 'com.huawei.hmos.maps.app',
              uri: 'maps://routes',
              parameters: {
                linkSource: 'com.other.app',
                destinationLatitude: 40.0382556,
                destinationLongitude: 116.3144536,
                destinationName: '清河站',
                originName: '香山公园',
                originLatitude: 39.9901079,
                originLongitude: 116.1887467
              },
            }
            context.startAbility(petalMapWant)
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
