Losing session after Login - Java
- by Patrick Villela
I'm building an application that needs to login to a certain page and make a navigation. I can login, provided that the response contains a string that identifies it. But, when I navigate to the second page, I can't see the page as a logged user, only as anonymous. I'll provide my code.
import java.net.*;
import java.security.*;
import java.security.cert.*;
import javax.net.ssl.*;
import java.io.*;
import java.util.*;
public class PostTest {
static HttpsURLConnection conn = null;
private static class DefaultTrustManager implements X509TrustManager {
@Override
public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
@Override
public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
}
public static void main(String[] args) {
try {
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(new KeyManager[0], new TrustManager[] {new DefaultTrustManager()}, new SecureRandom());
SSLContext.setDefault(ctx);
String data = URLEncoder.encode("txtUserName", "UTF-8") + "=" + URLEncoder.encode(/*username*/, "UTF-8");
data += "&" + URLEncoder.encode("txtPassword", "UTF-8") + "=" + URLEncoder.encode(/*password*/", "UTF-8");
data += "&" + URLEncoder.encode("envia", "UTF-8") + "=" + URLEncoder.encode("1", "UTF-8");
connectToSSL(/*login url*/);
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
String resposta = "";
while((line = rd.readLine()) != null) {
resposta += line + "\n";
}
System.out.println("valid login -> " + resposta.contains(/*string that assures me I'm looged in*/));
connectToSSL(/*first navigation page*/);
rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while((line = rd.readLine()) != null) {
System.out.println(line);
}
} catch(Exception e) {
e.printStackTrace();
}
}
private static void connectToSSL(String address) {
try {
URL url = new URL(address);
conn = (HttpsURLConnection) url.openConnection();
conn.setHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
});
} catch(Exception ex) {
ex.printStackTrace();
}
}
}
Any further information, just ask.
Thanks in advance.
