我一直在尝试发布我获得的用户的纬度和经度数据。我使用 WAMP 创建了一个服务器。它是一个以 mysql 作为数据库的 PHP 服务器。在这段代码中，我没有收到任何错误，但问题是它没有在 url 上发布任何内容。下面是 PHP 脚本和代码。

PHP

<?php

$con = mysql_connect("localhost","root","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("radhika_db", $con);

 $latitude = $_POST['latitude'];
 $longitude = $_POST['longitude'];
 $service = $_POST['service'];
 $devid = $_POST['devid'];



$sql = "INSERT INTO  `radhika_db`.`locations` (
`id` ,
`devid` ,
`latitude` ,
`longitude` ,
`service`
)
VALUES (
NULL ,  '$devid',  '$latitude',  '$longitude',  '$service'
);";
if (!mysql_query($sql,$con))
{
  die('Error: ' . mysql_error());
  }

mysql_close($con);

?>

使用Gps.java

public class UseGps extends Activity 

{ 


/** Called when the activity is first created. */ 

@Override 

public void onCreate(Bundle savedInstanceState) 

{ 

 super.onCreate(savedInstanceState); 

setContentView(R.layout.main); 



 /* Use the LocationManager class to obtain GPS locations */ 

LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); 

LocationListener mlocListener = new MyLocationListener(); 



mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener); 



} 



/* Class My Location Listener */ 

public class MyLocationListener implements LocationListener 

{ 
  Context context;
public void onLocationChanged(Location loc) 

{ 


double latitude = loc.getLatitude(); 

double longitude = loc.getLongitude(); 
Toast.makeText(context, "Latitude:" +latitude + "Longitude:" +longitude, 5000).show();}
TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService  (Context.TELEPHONY_SERVICE);
String Devid = telephonyManager.getDeviceId();




//this is JSON part to put your information inside it

    e1.printStackTrace();

    httpResponse = httpClient.execute(httpPost);
    HttpEntity httpEntity = httpResponse.getEntity();
    if (httpEntity != null) {

        instream = httpEntity.getContent();
        BufferedReader reader = new BufferedReader(new InputStreamReader(instream,"iso-8859-1"),8);
