Hello,
I now have a solution to my problem, as I only needed to authenticate
via HTTPS, encrypting username and password, get the session cookie,
and use this cookie for future HTTP communication. However, I would
like to understand why there was an IOException generated from a
getResponseMessage(), even though the response from the server was:
Received authentication challenge is null
Even though this would output to the log, the exception would be
thrown:
java.io.IOException: Received authentication challenge is null
If I remove that line, the cookies are pulled from the header with no
problem, and there is no exception.
public void onClick(View v) {
// Perform action on click
try {
URL url = new URL("https://www.mysite.com/session.xml";);
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setRequestMethod("POST");
/* used this to force verification (from example
http://25digital.blogspot.com/2008/02/account-authentication-api-y-android.html).
This is a security problem, as host is no longer validated, though
encryption remains between server and client
*
* needed because of Android bug
http://groups.google.com/group/android-developers/browse_thread/thread/cd8d3ba7652fd99b
*
*/
conn.setHostnameVerifier(new HostnameVerifier(){
public boolean verify (String hostname, SSLSession session) {
return true;
}
});
OutputStreamWriter outputStreamWriter = new OutputStreamWriter
(conn.getOutputStream());
outputStreamWriter.write("email=" + URLEncoder.encode("userName"));
outputStreamWriter.write("&");
outputStreamWriter.write("password=" + URLEncoder.encode
("userPassword"));
outputStreamWriter.flush();
outputStreamWriter.close();
// THIS FAILS
Log.i("login", "Response message: " + conn.getResponseMessage());
String[] cookies = conn.getHeaderField("set-cookie").split(";");
} catch (Exception e) {
Log.e("login", e.getMessage());
}
}
Thank you,
Steve
