I am returning values from the server side using a php wrapper via JSON. But the the following error occurs when I am returning the value to the client side.
This is my client side code
@Override
protected Boolean doInBackground(String... arg0) {
try {
// Setup the parameters
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("FirstNameToSearch",
strNameToSearch));
// Create the HTTP request
HttpParams httpParameters = new BasicHttpParams();
// Setup timeouts
HttpConnectionParams
.setConnectionTimeout(httpParameters, 45000);
HttpConnectionParams.setSoTimeout(httpParameters, 45000);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
HttpPost httppost = new HttpPost(
"http://172.16.12.142/etsmobile/menuload.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
String result = EntityUtils.toString(entity);
// Create a JSON object from the request response
JSONObject jsonObject = new JSONObject(result);
// Retrieve the data from the JSON object
pasName = jsonObject.getString("Name");
pasPost = jsonObject.getString("Post");
pasStation = jsonObject.getString("Station");
} catch (Exception ex) {
ex.printStackTrace();
}
return true;
}
This is my Server Side Code
<?php
$firstname = $_POST["FirstNameToSearch"];
$con = mysql_connect("localhost", "root", "") or die("Unable to connect to MySQL");
if (mysqli_connect_errno()) {
echo 'Database connection error: ' . mysqli_connect_error();
exit();
}
$selected = mysql_select_db("ets", $con) or die("Could not select ets");
$userdetails = mysql_query("SELECT users.* FROM login, users WHERE username = '$firstname' and login.emp_no=users.emp_no");
$getUser_result = mysql_fetch_assoc($userdetails);
$name = $getUser_result['name'];
$post = $getUser_result['post'];
$station = $getUser_result['station'];
mysql_close($con);
$result_data = array('Name' => $name, 'Post' => $post, 'Station' => $station);
//print_r($result_data);
echo json_encode($result_data);
?>
This is my JSON Output
{"Name":"Sameera Yatawara","Post":"Station Master","Station":"Dematagoda"}
Try retrieving data with something like this:
...
String result = EntityUtils.toString(entity);
JSONArray array = (JSONArray) new JSONTokener(result).nextValue();
JSONObject json = array.getJSONObject(0);
json.getString('name');
...
or
...
String result = EntityUtils.toString(entity);
JSONObject json = (JSONObject ) new JSONTokener(result).nextValue();
json.getString('name');
...
Also check the PHP script encoding. I had similar problem. I set encoding to UTF-8 with DOM in text editor (Notepad++,..) and it start working.
