HarmonyOS 鸿蒙Next routerMap中的 customData自定义数据如何获取

参考https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V13/js-apis-bundlemanager-hapmoduleinfo-V13#routeritem12，可以通过bundleManager.getBundleInfoForSelf()获取自身配置信息，当需要获取routerMap信息时bundleFlags参数传入GET_BUNDLE_INFO_WITH_HAP_MODULE和GET_BUNDLE_INFO_WITH_ROUTER_MAP获取，进而获取customData字符串或用JSON.parse()解析为对象

  let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_HAP_MODULE | bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_ROUTER_MAP;

 try {
   bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => {
     let routerMap = data.routerMap
     let jsonStr: string = '';
     for (let i = 0 ; i < routerMap.length; i++) {
       if (routerMap[i].name === 'Destination') {
         jsonStr = routerMap[i].customData
       }
     }
     let obj: XObject = JSON.parse(jsonStr)
     console.info('routerMap:' + jsonStr)
     hilog.info(0x0000, 'testTag', 'getBundleInfoForSelf successfully. Data: %{public}s', JSON.stringify(data));
   }).catch((err: BusinessError) => {
     hilog.error(0x0000, 'testTag', 'getBundleInfoForSelf failed. Cause: %{public}s', err.message);
   });
 } catch (err) {
   let message = (err as BusinessError).message;
   hilog.error(0x0000, 'testTag', 'getBundleInfoForSelf failed: %{public}s', message);
 }
