I have a sample example for posting json data .
Have a look at this:
public class LoginActivity extends Activity {
private static final String TAG = "LoginActivity";
private Context mContext;
private Intent mIntent;
private ProgressDialog pdLoading;
private class LoginTask extends AsyncTask<Void, Void, String>
{
private ArrayList<NameValuePair> mParams = new ArrayList<NameValuePair>();
private JSONArray mJArray = new JSONArray();
private JSONObject mJobject = new JSONObject();
private String jsonString = new String();
@Override
protected void onPreExecute() {
super.onPreExecute();
pdLoading.show();
}
@Override
protected String doInBackground(Void... params) {
try {
mJobject.put("userName", "test");
mJobject.put("password", "test");
mJArray.put(mJobject);
mParams.add(new BasicNameValuePair("message", mJArray.toString()));
jsonString = WebAPIRequest.postJsonData("http://putyoururlhere.com/login.php?", mParams);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
return jsonString;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
pdLoading.dismiss();
if(result!=null)
{
/* try {
mJobject = new JSONObject(jsonString);
if(mJobject.getString("Success").equals("True"))
{
mJArray = mJobject.getJSONArray("user");
JSONObject mUser = mJArray.getJSONObject(0);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}*/
Log.e(TAG, jsonString);
}
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initialization();
new LoginTask().execute();
}
private void initialization() {
mContext = this;
mIntent = new Intent();
pdLoading = new ProgressDialog(mContext);
pdLoading.setMessage("loading...");
}
}
and
public class WebAPIRequest {
public static String convertStreamToString(InputStream is)
throws IOException {
if (is != null) {
StringBuilder sb = new StringBuilder();
String line;
try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(is, "UTF-8"));
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
} finally {
is.close();
}
return sb.toString();
} else {
return "";
}
}
public static String postJsonData(String url, List<NameValuePair> params) {
String response_string = new String();
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
httppost.addHeader("Content-Type", "application/x-www-form-urlencoded");
try {
httppost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
String paramString = URLEncodedUtils.format(params, HTTP.UTF_8);
String sampleurl = url + "" + paramString;
Log.e("Request_Url", "" + sampleurl);
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
if (response != null) {
InputStream in = response.getEntity().getContent();
response_string = WebAPIRequest.convertStreamToString(in);
}
} catch (Exception e) {
e.printStackTrace();
}
return response_string;
}
}
EDIT :
try,
print_r(json_decode($_POST['message'], true);
or
$data = file_get_contents('php://input');
$json = json_decode($data,true);
I hope it will be helpful !!
