android username password send through json to php-->sql - php

Question

im trying to find a way to post username and password using json rather than normal http post that im currently using. i have being going through most of the tutorials and examples to undestand but yet i was unable to get an idea. i have json phasers available to get the data from my sql but not the post json.
thank you for the help
following is the currently used json post
EditText uname = (EditText) findViewById(R.id.log_Eu_name);
String username = uname.getText().toString();
EditText pword = (EditText) findViewById(R.id.log_Epass);
String password = pword.getText().toString();
String result = new String();
result = "";
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs
.add(new BasicNameValuePair("username", username));
nameValuePairs
.add(new BasicNameValuePair("password", password));
InputStream is = null;
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.loshwickphotography.com/log.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
Log.w("SENCIDE", "Execute HTTP Post Request");
String str = inputStreamToString(
response.getEntity().getContent()).toString();
Log.w("SENCIDE", str);
if (str.toString().equalsIgnoreCase("true")) {
Log.w("SENCIDE", "TRUE");
Toast.makeText(getApplicationContext(),
"FUking hell yeh!", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(),
"Sorry it failed", Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
Log.e("log_tag", "Error in http connection " + e.toString());
}
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());
}
try {
if (result != null) {
JSONArray jArray = new JSONArray(result);
Log.i("log_tag", Integer.toString(jArray.length()));
for (int i = 0; i < jArray.length(); i++) {
JSONObject json_data = jArray.getJSONObject(i);
}
} else {
Toast.makeText(getApplicationContext(), "NULL",
Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
Log.e("log_tag", "Error parsing data " + e.toString());
}
}
private Object inputStreamToString(InputStream is) {
// TODO Auto-generated method stub
String line = "";
StringBuilder total = new StringBuilder();
// Wrap a BufferedReader around the InputStream
BufferedReader rd = new BufferedReader(
new InputStreamReader(is));
// Read response until the end
try {
while ((line = rd.readLine()) != null) {
total.append(line);
}
} catch (IOException e) {
e.printStackTrace();
}
// Return full string
return total;
}
});
Is this correct which i have written?
how to write the Php for this?

Answer 1

use this
JSONObject myjson=new JSONObject();
myjson.put("userName", "someOne");
myjson.put("password", "123");
and StringEntity se = new StringEntity(myjson.toString());
and httpPost.setEntity(se);
