从安卓手机在服务器上发帖

Question

已经很久了，经过大量研究后，我无法找到我真正想要的解决方案。我制作了一个 GPS 跟踪应用程序。现在我想将我从手机获得的坐标发布到我的本地主机服务器。而且它也每 5 分钟发布一次坐标。我使用 WAMP 制作了一个服务器。

PHP 脚本

?php

echo 'Hello, world!';

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

mysql_select_db("ric_db", $con);

$devid = $_POST["devid"];
$latitude = $_POST["latitude"];
$longitude = $_POST["longitude"];





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

mysql_close($con);

?>

Java 文件

@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) 

{ 
StringBuilder sb = null;
   String result = null;
   InputStream is = null;

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
String postData = "{\"request\":{\"type\":\"locationinfo\"},\"userinfo\":{\"Devid\":\""+Devid+"\",\"latitude\":\""+latitude+"\",\"longitude\":\""+longitude+"\"}}";

String url="http://localhost/mehul/store.php";


List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("Devid", Devid));
nameValuePairs.add(new BasicNameValuePair("latitude", Double.toString(latitude) )); 
nameValuePairs.add(new BasicNameValuePair("longitude", Double.toString(longitude))); 

HttpClient httpclient = new DefaultHttpClient();

HttpPost httppost = new HttpPost(url);

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

HttpResponse response = httpclient.execute(httppost);

HttpEntity http_entity = response.getEntity();

Log.i("postData", response.getStatusLine().toString());
BufferedReader br = new BufferedReader(
new InputStreamReader(http_entity.getContent()));
String res = br.readLine();
System.out.println(res);


}





public void onProviderDisabled(String arg0) {
// TODO Auto-generated method stub

}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub

}
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub

}

请帮我解决这个问题...

不要在你的 url 中使用localhost，而是使用服务器的 IP 地址。 而且您的 PHP 脚本有错误的开始标记：?php 而不是 <?php

如果这没有帮助，请评论您会遇到什么错误...
