HarmonyOS 根据经纬度逆地理解析一直报错：BussinessError 3301000: Location service is unavailable.

1、定位权限module.json5已配置：

{
"name": "ohos.permission.LOCATION",
"reason": "$string:text_location_reason",
"usedScene": {
  "abilities": [
  "FormAbility"
  ],
  "when":"inuse"
}},
{
"name": "ohos.permission.APPROXIMATELY_LOCATION",
"reason": "$string:text_location_reason",
"usedScene": {
  "abilities": [
  "FormAbility"
  ],
  "when":"inuse"
}}

2、程序启动EntryAbility中onWindowStageCreate方法里已调用申请权限：

private async getLocal() {
  let permissions: Array<Permissions> = ["ohos.permission.LOCATION", "ohos.permission.APPROXIMATELY_LOCATION"]
  let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager()
  let auth = await atManager.requestPermissionsFromUser(this.context, permissions)
}

3、根据经纬度逆地理解析报错，代码：

let isAvailable = geoLocationManager.isGeocoderAvailable();
if (isAvailable) {
  try {
    let reverseGeocodeRequest:geoLocationManager.ReverseGeoCodeRequest = {"latitude": this.carConditionData.latitude, "longitude": this.carConditionData.longitude, "maxItems": 1};
    geoLocationManager.getAddressesFromLocation(reverseGeocodeRequest , (err, data) => {
      let str = 'lat:'+this.carConditionData.latitude+' lon:'+this.carConditionData.longitude
      let x = data
      if (!err) {
      }
    })
  } catch (err) {
    console.error("errCode:" + JSON.stringify(err));
  }
}

4、打断点一直报错：BussinessError 3301000: Location service is unavailable.网络连接个人手机热点，不存在网络不通情况。
