获取到的海拔altitude和邮政编码postalCode两个字段一直是空的

Answer 1

如果使用的是网络定位的话 那么是没有海拔返回的在室外，使用GPS定位一般都是有海拔返回的。

开发者可以尝试将LocationRequestPriority、LocationRequestScenario分别设置为ACCURACY、NAVIGATION。

再进行尝试后看是否能获取海拔和邮编https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-geolocationmanager-V5\#locationrequestscenario
