I am developing an android application which has an access to a php script and parse the result returned by the code php. The code php connects to the base and return a result. The problem is that I get an error : Error parsing data org.json.JSONException: Value
Thanks for your help :) Java code :
public class ville extends Activity {
TextView txt;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LinearLayout rootLayout = new LinearLayout(getApplicationContext());
txt = new TextView(getApplicationContext());
rootLayout.addView(txt);
setContentView(rootLayout);
// Définir le texte et appeler la fonction de connexion.
txt.setText("Connexion...");
// Appeler la méthode pour récupérer les données JSON
txt.setText(getServerData(strURL));
}
// Mettre l'adresse du script PHP
// Attention localhost ou 127.0.0.1 ne fonctionnent pas. Mettre l'adresse IP local.
public static final String strURL = "http://192.168.1.2/www/nouveaudossier/ville.php";
private String getServerData(String returnString) {
InputStream is = null;
String result = "";
// Envoyer la requête au script PHP.
// Script PHP : $sql=mysql_query("select * from tblVille where Nom_ville like '".$_REQUEST['ville']."%'");
// $_REQUEST['ville'] sera remplacé par L dans notre exemple.
// Ce qui veut dire que la requête enverra les villes commençant par la lettre L
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("Nom_ville","L"));
// Envoie de la commande http
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(strURL);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection " + e.toString());
}
// Convertion de la requête en string
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
}catch(Exception e){
Log.e("log_tag", "Error converting result " + e.toString());
}
// Parse les données JSON
try{
JSONArray jArray = new JSONArray(result);
for(int i=0;i<jArray.length();i++){
JSONObject json_data = jArray.getJSONObject(i);
// Affichage ID_ville et Nom_ville dans le LogCat
Log.i("log_tag","ID_ville: "+json_data.getInt("ID_ville")+
", Nom_ville: "+json_data.getString("Nom_ville")
);
// Résultats de la requête
returnString += "\n\t" + jArray.getJSONObject(i);
}
}catch(JSONException e){
Log.e("log_tag", "Error parsing data " + e.toString());
}
return returnString;
}
}
php code :
<?php
mysql_connect("localhost","root","password");
mysql_select_db("bdVille");
$sql=mysql_query("select * from tblVille where Nom_ville like '".$_REQUEST['ville']."%'");
while($row=mysql_fetch_assoc($sql))
$output[]=$row;
print(json_encode($output));
mysql_close();
?>
