Login and KeepAlive Examples

[trader174.]

Hi!
I am a not professional programmer.
I use apiNG example for building my bot.
I can't understand, how i can login through my bot, and how i can create keep alive request.

Please help me!
P.S. I use Netbeans

I found a solution in another post:

package com.XXX.XXXX;

import java.net.*;
import java.io.*;
import javax.net.ssl.HttpsURLConnection;


public class Authentication
{
private static String loginTarget = "https://identitysso.betfair.com/api/login";
private static String keepAliveTarget = "https://identitysso.betfair.com/api/keepAlive";
private static String logoutTarget = "https://identitysso.betfair.com/api/logout";


public Authentication()
{
;
}

public static String login(String username, String password)
{
String token = "PROBLEM";

String s = "";

try
{
s = "&username=" + URLEncoder.encode(username, "UTF-8");
s+= "&password=" + URLEncoder.encode(password, "UTF-8");

s+= "&url=" + URLEncoder.encode("https://www.betfair.com/", "UTF-8");
}
catch(Exception ex)
{
ex.printStackTrace();
}

if(!s.equals(""))
token = makeCall(0, loginTarget, s);

return token;
}

public static String keepAlive()
{

outStream.writeBytes(query);
outStream.flush();
outStream.close();
conn.disconnect();

int responseCode = conn.getResponseCode();

{
if(responseCode == 200)
{

{

{
String cookie = conn.getHeaderField(i);

if(cookie.indexOf("ssoid") > -1)
outString = cookie.substring(cookie.indexOf("=") + 1, cookie.indexOf(";"));
}
}
}
}

else if(responseCode == 200)
outString = "" + responseCode;

}
