HarmonyOS 如何获取用户所在省市区？

//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)) 
      } 
    }) 
  } 
})
