HarmonyOS 内网环境定位失败

定位失败是因为http请求失败，需调整内网防火墙设置。无法收到回调是由于只有在定位成功的情况下才能触发回调，可以通过geoLocationManager.on('locationError')注册定位错误的监听，并根据不同错误码执行相应的业务操作。

onForeground(): void {
  // Ability has brought to foreground
  hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onForeground');

  // 增加监听定位状态改变
  let locationEnabledChange = (state:boolean):void => {
    console.log('locationEnabledChange: ' + JSON.stringify(state));
    this.context.eventHub.emit('refreshState', state)
  }
  try {
  geoLocationManager.on('locationEnabledChange', locationEnabledChange);
} catch (err) {
}
