HarmonyOS 路由跳转怎么接收参数

参考代码：

//定义类
export class routerParams {
  key: string
  value: string

  constructor(key: string, value: string) {
    this.key = key
    this.value = value
  }
}
//跳转代码
buildRouterModel(RouterNameConstants.ENTRY_HAP, BuilderNameConstants.H5_PAGE,
  new routerParams('www.index.com', '点击'))
@Builder
export function harBuilder(value: routerParams) {
  NavDestination() {
    Column() {
      //这儿解析出来是对的
      Text(传入的参数：${JSON.stringify(value)}).onClick(() => {
      })
      //下=？？？
      H5Page({ url: value?.key }
      )
    }
    .width('100%')
    .height('100%')
  }
  .title('登录')
  .onBackPressed(() => {
    RouterModule.pop(RouterNameConstants.ENTRY_HAP);
    return true;
  }).hideTitleBar(true)
}
