Smack和SASL身份验证错误-没有已知的身份验证机制

Question

I am trying to create an XMPP client using the latest version of Smack 4.1.0-beta. But i am running into an error when trying login into a local running OpenFire server.

org.jivesoftware.smack.SmackException: SASL Authentication failed. No known authentication mechanisims.

I tried all kind of combinations of user credentials but so far no luck. When trying to connect to the server with Pidgin or Adium al is ok. Any clue what i am missing in the code?

XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
            .setUsernameAndPassword("admin", "admin")
            .setServiceName("localhost")
            .setHost("localhost")
            .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
            .setPort(5222)
            .build();

    AbstractXMPPConnection connection = new XMPPTCPConnection(config);

    try {

        connection.connect();

        connection.login();

        connection.disconnect();

    } catch (SmackException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (XMPPException e) {
        e.printStackTrace();
    }

Here is the complete solution please look at this carefully...

public class NewClientActivity extends Activity {
    EditText etUsername, etPassword;
    Button bSubmit;
    AbstractXMPPConnection mConnection;
    ConnectionListener connectionListener = new ConnectionListener() {
        @Override
        public void connected(XMPPConnection xmppConnection) {
            Log.d("xmpp", "connected");
            try {
                SASLAuthentication.registerSASLMechanism(new SASLMechanism() {
                    @Override
                    protected void authenticateInternal(CallbackHandler callbackHandler) throws SmackException {

                    }

                    @Override
                    protected byte[] getAuthenticationText() throws SmackException {
                        byte[] authcid = toBytes('\u0000' + this.authenticationId);
                        byte[] passw = toBytes('\u0000' + this.password);
                        return ByteUtils.concact(authcid, passw);
                    }

                    @Override
                    public String getName() {
                        return "PLAIN";
                    }

                    @Override
                    public int getPriority() {
                        return 410;
                    }

                    @Override
                    public void checkIfSuccessfulOrThrow() throws SmackException {

                    }

                    @Override
                    protected SASLMechanism newInstance() {
                        return this;
                    }
                });
                mConnection.login();
            } catch (XMPPException e) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(NewClientActivity.this, "Incorrect username or password", Toast.LENGTH_LONG).show();
                    }
                });
                e.printStackTrace();
            } catch (SmackException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        @Override
        public void authenticated(XMPPConnection xmppConnection, boolean b) {
            Log.d("xmpp", "authenticated");
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    Toast.makeText(NewClientActivity.this,"Logged in successfully...",Toast.LENGTH_LONG ).show();
                }
            });
        }

        @Override

        }

        @Override

        public void reconnectionFailed(Exception e) {
            Log.d("xmpp", "reconnection failed");
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_new_client);
        findViews();
    }

    private void findViews() {
        etUsername = (EditText) findViewById(R.id.etUsername);
        etPassword = (EditText) findViewById(R.id.etPassword);
        bSubmit = (Button) findViewById(R.id.bSubmit);
        bSubmit.setOnClickListener(new View.OnClickListener() {
            @Override

                String[] params = new String[]{etUsername.getText().toString(), etPassword.getText().toString()};
                new Connect().executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);
            }
        });
    }

    class Connect extends AsyncTask<String, Void, Void> {
        @Override
        protected Void doInBackground(String... params) {

            XMPPTCPConnectionConfiguration config = null;

            builder.setServiceName("192.168.1.60").setHost("192.168.1.60")
                    .setDebuggerEnabled(true)
                    .setPort(5222)
                    .setUsernameAndPassword(params[0], params[1])
                    .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
                    .setCompressionEnabled(false);
            config = builder.build();

            mConnection = new XMPPTCPConnection(config);
            try {
                mConnection.setPacketReplyTimeout(10000);

            } catch (XMPPException e) {
                e.printStackTrace();
            }
            return null;
        }
    }
}

Update :- For smack 4.2.0-beta2 version use below code to configure XmppConnection for PLAIN authentication.

XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();
builder.setHost("example.com");
builder.setPort(5222);
/*builder.setServiceName("example.com");*/ //for older version < 4.2.0-beta2
try
{
    builder.setXmppDomain(JidCreate.domainBareFrom("example.com"));
}
catch (XmppStringprepException e)
{
    e.printStackTrace();
}
/*builder.setServiceName("example.com");*/
builder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
builder.setCompressionEnabled(true);
builder.setConnectTimeout(30000);
/*builder.setSendPresence(false);*/
try
{
    TLSUtils.acceptAllCertificates(builder);
}
catch (NoSuchAlgorithmException|KeyManagementException e)
{
    e.printStackTrace();
}
TLSUtils.disableHostnameVerificationForTlsCertificates(builder);
final Map<String, String> registeredSASLMechanisms = SASLAuthentication.getRegisterdSASLMechanisms();
for(String mechanism:registeredSASLMechanisms.values())
{
    SASLAuthentication.blacklistSASLMechanism(mechanism);
}
SASLAuthentication.unBlacklistSASLMechanism(SASLPlainMechanism.NAME);

xmppConnection=new XMPPTCPConnection(builder.build());

I wrongly imported the wrong dependencies. When checking out the documentation ( https://github.com/igniterealtime/Smack/wiki/Smack-4.1-Readme-and-Upgrade-Guide ) importing the correct dependencies using Gradle solved the issue.

compile("org.igniterealtime.smack:smack-java7:4.1.0-beta1")
compile("org.igniterealtime.smack:smack-tcp:4.1.0-beta1")
compile("org.igniterealtime.smack:smack-extensions:4.1.0-beta1")
