Depending on your server-side language, you can pass the json parameters by adding parameter as a string e.g
For passing parameters to a PHP server-side
String url = "http://www.test.com/test.php?";
url += "method=" + session.getToken;
url += "&phonenumber:=1212345687";
url += "&PIN:=1234";
For your response.. try this
public void get()
{
HttpConnection connection = null;
String results;
byte responseData[] = null;
try {
connection = (HttpConnection) new
ConnectionFactory().getConnection(URL).getConnection();
int len = (int) connection.getLength();
responseData = new byte[len];
DataInputStream dis;
dis = new DataInputStream(connection.openInputStream());
dis.readFully(responseData);
results = new String(responseData);
screen.add(new RichTextField("Reponce Message: "+results));
} catch (Exception e) {
// TODO Handle exception
screen.add(new RichTextField(""+e));
}
}
