用java将LAC:00008015 和CID:00000CFC3281转换成为经纬度
由于LAC和CID只是基站的标识符,无法直接转换成经纬度,需要借助基站定位技术来实现。
一种常用的方法是使用Google Maps API或其它基站定位服务提供商的API,通过发送LAC和CID信息查询基站的位置信息,进而得到对应的经纬度。
以下是一个使用Google Maps API实现的示例代码:
import java.io.*;
import java.net.*;
import org.json.*;
public class LocationConverter {
public static void main(String[] args) throws Exception {
String lac = "00008015";
String cid = "00000CFC3281";
String url = "https://www.googleapis.com/geolocation/v1/geolocate?key=YOUR_API_KEY";
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
// set request method
con.setRequestMethod("POST");
// set request headers
con.setRequestProperty("Content-Type", "application/json");
// set request body
String requestBody = "{\"considerIp\": \"false\", \"cellTowers\": [{\"cellId\": \"" + cid + "\", \"locationAreaCode\": \"" + lac + "\", \"mobileCountryCode\": 460, \"mobileNetworkCode\": 0}]}";
con.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(con.getOutputStream());
writer.write(requestBody);
writer.flush();
// get response
int responseCode = con.getResponseCode();
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
// parse response
JSONObject jsonResponse = new JSONObject(response.toString());
double lat = jsonResponse.getJSONObject("location").getDouble("lat");
double lng = jsonResponse.getJSONObject("location").getDouble("lng");
System.out.println("Latitude: " + lat + ", Longitude: " + lng);
}
}
其中,YOUR_API_KEY需要替换为自己的Google Maps API密钥。运行该程序,即可得到对应的经纬度信息
