HarmonyOS 如何获取用户所在省市区？

Answer 1

请参考指南中位置服务链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-geolocationmanager-V5\#reversegeocoderequest

首先申请权限，并且获得用户授权，再调用geoLocationManager.getCurrentLocation获取经纬度数据，最后调用geoLocationManager.getAddressesFromLocation获取用户所在省市区信息。代码如下：

//获取当前的地理位置
geoLocationManager.getCurrentLocation((err, location) => {
  if (err) {
    console.log('location getCurrentLocation err = ' + JSON.stringify(err))
  }
  if (location) {
    console.log('location getCurrentLocation = ' + JSON.stringify(location))
    //{"latitude":40,"longitude":116,"altitude":43.5,"accuracy":5,"speed":0,"timeStamp":1704176491,"direction":45,"timeSinceBoot":13563917977759,"additions":"","additionSize":0,"isFromMock":false}
    let latitude = location.latitude
    let longitude = location.longitude
    let maxItems = 1
    let reverseGeocodeReq:geoLocationManager.ReverseGeoCodeRequest = { 'latitude': latitude, 'longitude': longitude, 'maxItems': maxItems }
    //根据坐标转化为地理描述
    geoLocationManager.getAddressesFromLocation(reverseGeocodeReq, (err, val) => {
      if (err) {
        console.log('location getAddressesFromLocation err = ' + JSON.stringify(err))
        //{"code":3301300,"message":"BussinessError 3301300: Reverse geocoding query failed."}
      }
      if (val) {
        console.log('location getAddressesFromLocation = ' + JSON.stringify(val))
      }
    })
  }
})
