Hi,
First off, sorry to bring up this question about this error message:
SASL authentication X-FACEBOOK-PLATFORM failed: not-authorized
I am building a simple facebook chat client using JAVA, smack and X-FACEBOOK-PLATFORM for authentication for school project.
I have a valid access token through the facebook-documented client side flow. I have the xmpp_permissions obtained.
I found the custom X-FACEBOOK-PLATFORM elsewhere on this forums and stackoverflow. Trying to reuse it, but getting the above said error.
Here is the class and the code.
import java.io.IOException;import java.net.URLEncoder;import java.util.GregorianCalendar;import java.util.HashMap;import java.util.Map; import javax.security.sasl.Sasl; import org.jivesoftware.smack.SASLAuthentication;import org.jivesoftware.smack.XMPPException;import org.jivesoftware.smack.sasl.SASLMechanism;import org.jivesoftware.smack.util.Base64; publicclass SASLXFacebookPlatformMechanism extends SASLMechanism { publicstaticfinal String NAME = "X-FACEBOOK-PLATFORM"; private String apiKey = ""; private String accessToken = ""; /** * Constructor. */ public SASLXFacebookPlatformMechanism(SASLAuthentication saslAuthentication) { super(saslAuthentication); } @Override protectedvoid authenticate() throws IOException, XMPPException { // Send the authentication to the server getSASLAuthentication().send(new AuthMechanism(getName(), "")); } @Override publicvoid authenticate(String apiKey, String host, String accessToken) throws IOException, XMPPException { this.apiKey = apiKey; this.accessToken = accessToken; this.hostname = host; String[] mechanisms = {"DIGEST-MD5"}; Map<String, String> props = new HashMap<String, String>(); this.sc = Sasl.createSaslClient(mechanisms, null, "xmpp", host, props, this); authenticate(); } @Override protected String getName() { return NAME; } @Override publicvoid challengeReceived(String challenge) throws IOException { byte[] response = null; if (challenge != null) { String decodedChallenge = new String(Base64.decode(challenge)); Map<String, String> parameters = getQueryMap(decodedChallenge); String version = "1.0"; String nonce = parameters.get("nonce"); String method = parameters.get("method"); long callId = new GregorianCalendar().getTimeInMillis() / 1000L; String composedResponse = "api_key=" + URLEncoder.encode(apiKey, "utf-8") + "&call_id=" + callId + "&method=" + URLEncoder.encode(method, "utf-8") + "&nonce=" + URLEncoder.encode(nonce, "utf-8") + "&access_token=" + URLEncoder.encode(accessToken, "utf-8") + "&v=" + URLEncoder.encode(version, "utf-8"); response = composedResponse.getBytes("utf-8"); } String authenticationText = ""; if (response != null){ authenticationText = Base64.encodeBytes(response, Base64.DONT_BREAK_LINES); } // Send the authentication to the server getSASLAuthentication().send(new Response(authenticationText)); } private Map<String, String> getQueryMap(String query) { Map<String, String> map = new HashMap<String, String>(); String[] params = query.split("\\&"); for (String param : params) { String[] fields = param.split("=", 2); map.put(fields[0], (fields.length > 1 ? fields[1] : null)); } return map; } }
Here is the main code:

I searched, but found mostly old post from 2012 and also with no working solutions for me. Whatever minor changes were suggested I tried them. But to no use.
Any kind of help is appreciated. Also, very much a java and smack newbie here. So even the basic errors I might have done, please do point out and guide me. Thanks in advance.
