坐标返回地址的回调函数如何写？

function address(lat,lng){
request('https://maps.googleapis.com/maps/api/geocode/json?latlng='+ lat +','+ lng +'&sensor=false', function (error, response, data) {
  if (!error && response.statusCode == 200) {
        
        //var dd = JSON.stringify(data);
        //console.log(data);
        var result = JSON.parse(data);
        var dd = JSON.stringify(result);
        //console.log(result);
        var address = result.results[0].formatted_address;
        console.log(address)
        return address;
  }
})}
            console.log(address(22.333,113.5555));
