I'm writing a client j2me app that connects to a php based api using a post method. For security purposes the app and the api should interact within a session with a 30 minutes timeout. My problem is that, the application user has to keep on logging in even when the session time out is not yet done. My php code is fine because I've tested it on a browser and it works fine; however but the application fails and I have to keep on logging in. Might I be missing something? These are the headers am sending to the server using my Java app.
String phonenumber = this.phonenumberTextbox.getString();
String password = this.passwordTextBox.getString();
HttpConnection httpConn = null;
String url = "http://192.168.56.1/?action=login-user";
InputStream is;
OutputStream os;
is = null;
os = null;
String sReply = "";
boolean loggedIn = false;
try {
// Open an HTTP Connection object
httpConn = (HttpConnection) Connector.open(url);
// Setup HTTP Request to POST
httpConn.setRequestMethod(HttpConnection.POST);
httpConn.setRequestProperty("User-Agent", "Profile/MIDP-1.0 Confirguration/CLDC-1.0");
httpConn.setRequestProperty("Accept_Language", "en-US");
//Content-Type is must to pass parameters in POST Request
httpConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
os = httpConn.openOutputStream();
String params;
params = "phonenumber=" + phonenumber + "&password=" + password;
os.write(params.getBytes());
// Read Response from the Server
StringBuffer sb = new StringBuffer();
is = httpConn.openDataInputStream();
int chr;
while ((chr = is.read()) != -1) {
sb.append((char) chr);
}
// Web Server just returns stuff
sReply = sb.toString();
} catch (IOException ex) {
System.out.println("Cannot find server");
} finally {
if (is != null) {
try {
is.close();
} catch (IOException ex) {
}
}
if (os != null) {
try {
os.close();
} catch (IOException ex) {
}
}
if (httpConn != null) {
try {
httpConn.close();
} catch (IOException ex) {
}
}
}
// do something with sReply
