我正在尝试使用最新版本的Smack 4.1.0-beta创建一个XMPP客户端.但是当我尝试登录到本地运行的OpenFire服务器时,我遇到了错误.
org.jivesoftware.smack.SmackException: SASL Authentication failed. No known authentication mechanisims.
我尝试了各种用户凭证的组合,但到目前为止还没有运气.当尝试使用Pidgin或Adium连接到服务器时,可以.任何线索我在代码中缺少什么？
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();
}
解决方法:
这是完整的解决方案,请仔细看看……
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
public void connectionClosed() {
Log.d("xmpp", "connection closed");
}
@Override
public void connectionClosedOnError(Exception e) {
Log.d("xmpp", "cononection closed on error");
}
@Override
public void reconnectionSuccessful() {
Log.d("xmpp", "reconnection successful");
}
@Override
public void reconnectingIn(int i) {
Log.d("xmpp", "reconnecting in " + i);
}
@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
public void onClick(View v) {
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;
XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();
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);
mConnection.addConnectionListener(connectionListener);
mConnection.connect();
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
e.printStackTrace();
}
return null;
}
}
}
更新： – 对于smack 4.2.0-beta2版本,使用以下代码配置XmppConnection进行PLAIN身份验证.
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.disableHostnameVerificationForTlsCertificicates(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());
