HarmonyOS 使用定位库获取定位时海拔高度字段无值

这边写了一个demo，altitude可以取到不为0的值：

// 需要引入@ohos.geoLocationManager模块
import { geoLocationManager } from '@kit.LocationKit';
import { MapComponent, mapCommon, map } from '@kit.MapKit';
import { FaultLogger } from '@kit.PerformanceAnalysisKit';
import { Logger } from '../commen.util/Logger';
@Entry
@Component
struct AltitudeIsNullTest{
  private mapController?: map.MapComponentController;
  aboutToAppear(): void {
    this.getAltitude()
  }
  getAltitude(){
    // 获取用户位置坐标
    let latitude: number = 0;
    let longitude: number = 0;
    geoLocationManager.getCurrentLocation().then((result) => {
      console.log('current location: ' + JSON.stringify(result));
      latitude = result.latitude;
      longitude = result.longitude;
    });
    // 设置用户的位置
    let position: geoLocationManager.Location = {
      "latitude": latitude,
      "longitude": longitude,
      "altitude": 1,
      "accuracy": 0,
      "speed": 0,
      "timeStamp": 0,
      "direction": 0,
      "timeSinceBoot": 0
    };
     Logger.info('altitude的值为：'+position.altitude)
  }
  build() {
  }
}
