I am attempting to authenticate via Oauth2 to an API however, I had trouble creating the request because of a private key. I was provided a sample code by the vendor which is Java and I converted it over to C# but I can't seem to get the private key into the JWT request.
Side note, the client, secret and URL's have been masked for this example.

I want to test if a given file exists at a remote SFTP server using Apache Camel.
The method has to return true if exists, false if not and an Exception in case
the client cannot get connected (timeout, wrong username/password, etc).
In fact to test if I can get logged in to the server is not a major problem
to test if the given file exists. Just send a request to the SFTP server, download=false and noop=true
and this is pretty much what it has to be done. An empty file will be downloaded to my TMP directory
in case the file exists, no file will be downloaded. In case I cannot logged in to the server an own Exception is thrown
(CannotConnectException).
My point is that I cannot catch this exception at my client.
I am pretty sure I am doing something wrong, but I do not know what.
I was thinking as a work around to set some error value in returned file is case I cannot get connected, but
this looks like a "hack" to me. Is there any way to catch the thrown exception? If not, what is the best way to
get an Exception my client in case I cannot get connected?
My code is as follows:
public final class MyFtpClient {
private static final Logger LOG = LoggerFactory.getLogger(MyFtpClient.class);
// Client settings
static String localPath = File.separator + "tmp";
public enum Existence{
EXIST, NOT_EXIST, UNKNOWN
}
private MyFtpClient() {
}
private static Existence doesFileExistAtServer(Main main, String protocol, String user, String password,
String server, int port, String filePathAtServer, String filenameAtServer, String localPath)
{
boolean fileExist = false;
try {
main.addRouteBuilder(new MyFtpClientRouteBuilder(protocol, user, password, server, port, filePathAtServer,
filenameAtServer, localPath));
main.start();
Thread.sleep(5000);
main.stop();
String filePath = localPath + File.separator + filenameAtServer;
File f = new File(filePath);
fileExist = f.exists();
if (fileExist) {
f.delete(); // Just delete it.
return Existence.EXIST;
} else {
return Existence.NOT_EXIST;
}
// I CANNOT CATCH THIS EXCEPTION
} catch (Exception e) {
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Cannot Connect to the Sftp Server " + server);
LOG.info(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Cannot Connect to the Sftp Server " + server);
LOG.info(e.getMessage());
return Existence.UNKNOWN;
}
}
public static void main(String[] args) throws Exception {
String protocol = "sftp";
int port = 22;
String server;
String user;
String password;
String filePathAtServer;
String filenameAtServer;
boolean fileExist;
Main main = new Main();
server = "unknown.com";
user = "demo";
password = "password";
filePathAtServer = "/";
filenameAtServer = "readme.txt";

LOG.info("\nThe accesibility of the file 1 " + filenameAtServer + " at the server " + server + " is " + fileExist + "\n")
}

I need to make a connection to the Granite Database using the ASI installed on the WebLogic application server 10.3.6.
The programming language is Java:
public void connect() throws Exception {
if (prop != null) {
ConnectionFactoryASI.setProtocol(prop);
ConnectionFactoryASI.setDataObjectFactoryType(prop);
serviceFactory = ConnectionFactoryASI.getServiceFactory(prop);
} else {
serviceFactory = ConnectionFactoryASI.getServiceFactory(user);
}
dataObjectFactory = serviceFactory.getDataObjectFactory();
setUser(serviceFactory.getClientSession().getLoginName());
logger.debug("ASI HostName: " + serviceFactory.getClientSession().getHostName()
+ ", DatabaseName: " + serviceFactory.getClientSession().getDatabaseName()
+ ", DbHostName: " + serviceFactory.getClientSession().getDbHostName());
}
It does not connect and gives me a connection error.
the ASI need a connection ticketName, without which you can not open a connection.
Here is the correct code, I added the parameter written above:
public void connect(String ticketName) throws Exception {
if (prop != null) {
ConnectionFactoryASI.setProtocol(prop);
ConnectionFactoryASI.setDataObjectFactoryType(prop);
serviceFactory = ConnectionFactoryASI.getServiceFactory(prop, ticketName);
} else {
serviceFactory = ConnectionFactoryASI.getServiceFactory(ticketName, user);
}
dataObjectFactory = serviceFactory.getDataObjectFactory();
setUser(serviceFactory.getClientSession().getLoginName());
logger.debug("ASI HostName: " + serviceFactory.getClientSession().getHostName()
+ ", DatabaseName: " + serviceFactory.getClientSession().getDatabaseName()
+ ", DbHostName: " + serviceFactory.getClientSession().getDbHostName());
}
I'm trying to make a Facebook Chat on Android with the Smack library. I've read the Chat API from Facebook, but I cannot understand how I have to authenticate with Facebook using this library.
Can anyone point me how to accomplish this?
Update: According to the no.good.at.coding answer, I have this code adapted to the Asmack library. All works fine except I receive as response to the login: not-authorized. Here is the code I use:
public class SASLXFacebookPlatformMechanism extends SASLMechanism
{
private static final String NAME = "X-FACEBOOK-PLATFORM";
private String apiKey = "";
private String applicationSecret = "";
private String sessionKey = "";
/**

public SASLXFacebookPlatformMechanism(SASLAuthentication saslAuthentication)
{

}
#Override

}
#Override
public void authenticate(String apiKeyAndSessionKey, String host,

{
throw new IllegalArgumentException("Invalid parameters");
}
String[] keyArray = apiKeyAndSessionKey.split("\\|", 2);
if (keyArray.length < 2)
{
throw new IllegalArgumentException(
"API key or session key is not present");
}
this.apiKey = keyArray[0];
Log.d("API_KEY", apiKey);
this.applicationSecret = applicationSecret;
Log.d("SECRET_KEY", applicationSecret);
this.sessionKey = keyArray[1];
Log.d("SESSION_KEY", sessionKey);
this.authenticationId = sessionKey;
this.password = applicationSecret;
this.hostname = host;
String[] mechanisms = { "DIGEST-MD5" };
Map<String, String> props = new HashMap<String, String>();

response = composedResponse.getBytes("utf-8");
}
String authenticationText = "";
if (response != null)
{

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;
}
private String md5(String text) throws NoSuchAlgorithmException,
UnsupportedEncodingException
{
MessageDigest md = MessageDigest.getInstance("MD5");
md.update(text.getBytes("utf-8"), 0, text.length());
return convertToHex(md.digest());
}
private String convertToHex(byte[] data)
{
StringBuilder buf = new StringBuilder();
int len = data.length;
for (int i = 0; i < len; i++)
{
int halfByte = (data[i] >>> 4) & 0xF;
int twoHalfs = 0;
do
{
if (0 <= halfByte && halfByte <= 9)
{
buf.append((char) ('0' + halfByte));
}
else
{
buf.append((char) ('a' + halfByte - 10));
}
halfByte = data[i] & 0xF;
} while (twoHalfs++ < 1);
}
return buf.toString();
}
}
And this, is the communication with the server with the sent and received messages:

As read in the developers Facebook forum, it is needed to disable the "Disable Deprecated Auth Methods" setting from the Facebook settings page of your app. But, even doing that, I can't login. And the session key is the second part of the OAuth token in the form AAA|BBB|CCC, I mean, BBB.
Finally, thanks to the no.good.at.coding code and the suggestion of harism, I've been able to connect to the Facebook chat. This code is the Mechanism for the Asmack library (the Smack port for Android). For the Smack library is necessary to use the no.good.at.coding mechanism.

To use it:
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
config.setSASLAuthenticationEnabled(true);
XMPPConnection xmpp = new XMPPConnection(config);
try
{
SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM", SASLXFacebookPlatformMechanism.class);
SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);
xmpp.connect();
xmpp.login(apiKey + "|" + sessionKey, sessionSecret, "Application");
} catch (XMPPException e)
{
xmpp.disconnect();
e.printStackTrace();
}
apiKey is the API key given in the application settings page in Facebook. sessionKey is the second part of the access token. If the token is in this form, AAA|BBB|CCC, the BBB is the session key. sessionSecret is obtained using the old REST API with the method auth.promoteSession. To use it, it's needed to make a Http get to this url:
https://api.facebook.com/method/auth.promoteSession?access_token=yourAccessToken
Despite of the Facebook Chat documentation says that it's needed to use your application secret key, only when I used the key that returned that REST method I was able to make it works. To make that method works, you have to disable the Disable Deprecated Auth Methods option in the Advance tab in your application settings.
I'd used this about 6 months ago with Smack (not asmack) so I'm not sure how it'll hold up now but here goes, hope it helps!
I found an implementation of Facebook's X-FACEBOOK-PLATFORM authentication mechanism on the Ignite Realtime Smack forum where someone got it from the fbgc project. You'll find the a ZIP with the SASLXFacebookPlatformMechanism.java source in the answer I linked to. You can use it as follows:
public void login() throws XMPPException
{
SASLAuthentication.registerSASLMechanism(SASLXFacebookPlatformMechanism.NAME,
SASLXFacebookPlatformMechanism.class);
SASLAuthentication.supportSASLMechanism(SASLXFacebookPlatformMechanism.NAME, 0);
ConnectionConfiguration connConfig = new ConnectionConfiguration(host, port);
XMPPConnection connection = new XMPPConnection(connConfig);
connection.connect();
log.info("XMPP client connected");
connection.login(Utils.FB_APP_ID + "|" + this.user.sessionId, Utils.FB_APP_SECRET, "app_name");
log.info("XMPP client logged in");
}
I was doing this on the server without an SDK. I don't remember the details (and the Facebook documentation isn't very good) but from what I can tell from my code, after getting the user to authorize the app, I get a callback request from Facebook with a code parameter. I open a URLConnection to https://graph.facebook.com/oauth/access_token?client_id=<app_id>&redirect_uri=http://myserver/context/path/&client_secret=<app_secret>&code=<code>. The response should be the access token where the session id is the part after the | - something of the form XXX|<sessionId>.
Here's code I've been using successfully for authentication. Maybe this helps even though this is not related to Smack in any way. You can get sessionKey from access token received from FB, and for getting sessionSecret I've been using oldish REST API;
http://developers.facebook.com/docs/reference/rest/auth.promoteSession/
private final void processChallenge(XmlPullParser parser, Writer writer,

What do you want to do?
If you just want to login on FB chat, you connect to FB just like any other XMPP server.
I would look at and use "Authenticating with Username/Password" from Chat API, wich is supported by Smack. Unless I would like to write an FaceBook-application. Then I would try to login in with "Authenticating with Facebook Platform".
So, just use Smack to connect to FB chat as you would do with your ordinary Jabber client.
For the username, use your Facebook username. (see http://www.facebook.com/username/ )
For the domain, use: chat.facebook.com
For the password, use your Facebook password
Turn off SSL and TSL
Set connect port to: 5222 (which is the default for XMPP)
Set connect server to chat.facebook.com
