Web({ src: $rawfile('call.html'), controller: this.controller })
  .onLoadIntercept((event) => {
    if (event) {
      let url: string = event.data.getRequestUrl();
      if (url.indexOf('store://') === 0) {
        const want: Want = {
          uri: `store://appgallery.huawei.com/`
        }
        const context = getContext(this) as common.UIAbilityContext;
        context.startAbility(want).then(() => {
        }).catch(() => {
        })
        return true;
      }
    }
    return false;
  })
