Vijay,
你的代码对我帮助很大，谢谢！我在这里发帖是为了提供我的解决方案来解决使用AccountManager登录Google talk的问题。到目前为止，我还没有找到完整的解决方案，但我根据上面的代码开发了我的解决方案，并纠正了一些不起作用的行。
解决方案有两个部分。第一个是基于上面的思路和代码。就是创建SASL机制的子类：
import java.io.IOException;
import java.net.URLEncoder;
import org.jivesoftware.smack.SASLAuthentication;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Packet;
import org.jivesoftware.smack.sasl.SASLMechanism;
import android.util.Base64;
import android.util.Log;
public class GTalkOAuth2 extends SASLMechanism {
public static final String NAME="X-GOOGLE-TOKEN";
public GTalkOAuth2(SASLAuthentication saslAuthentication) {
super(saslAuthentication);
}
@Override
protected String getName() {
return NAME;
}
static void enable() { }
@Override
protected void authenticate() throws IOException, XMPPException
{
String authCode = password;
String jidAndToken = "\0" + URLEncoder.encode( authenticationId, "utf-8" ) + "\0" + authCode;
StringBuilder stanza = new StringBuilder();
stanza.append( "<auth mechanism=\"" ).append( getName() );
stanza.append( "\" xmlns=\"urn:ietf:params:xml:ns:xmpp-sasl\">" );
stanza.append( new String(Base64.encode( jidAndToken.getBytes( "UTF-8" ), Base64.DEFAULT ) ) );
stanza.append( "</auth>" );
Log.v("BlueTalk", "Authentication text is "+stanza);
// Send the authentication to the server
getSASLAuthentication().send( new Auth2Mechanism(stanza.toString()) );
}
public class Auth2Mechanism extends Packet {
String stanza;
public Auth2Mechanism(String txt) {
stanza = txt;
}
public String toXML() {
return stanza;
}
}
/**
* Initiating SASL authentication by select a mechanism.
*/
public class AuthMechanism extends Packet {
final private String name;
final private String authenticationText;
public AuthMechanism(String name, String authenticationText) {
if (name == null) {
throw new NullPointerException("SASL mechanism name shouldn't be null.");
}
this.name = name;
this.authenticationText = authenticationText;
}
public String toXML() {
StringBuilder stanza = new StringBuilder();
stanza.append("<auth mechanism=\"").append(name);
stanza.append("\" xmlns=\"urn:ietf:params:xml:ns:xmpp-sasl\">");
if (authenticationText != null &&
authenticationText.trim().length() > 0) {
stanza.append(authenticationText);
}
stanza.append("</auth>");
return stanza.toString();
}
}
}
第二部分是它的使用。没有其他示例给我的重要一点是，当从 AccountManager 系统获取令牌时，令牌类型不是“ah”而是“mail”。这个想法存在于与谷歌服务器直接通信以获取令牌的示例中，但不是从 AccountManager 请求它。将它们放在一起意味着您需要在驱动程序代码中执行以下操作。创建一个函数来获取令牌：
public String getAuthToken(String name)
{
Context context = getApplicationContext();
Activity activity = this;
String retVal = "";
Account account = new Account(name, "com.google");
AccountManagerFuture<Bundle> accFut = AccountManager.get(context).getAuthToken(account, "mail", null, activity, null, null);
try
{
Bundle authTokenBundle = accFut.getResult();
retVal = authTokenBundle.get(AccountManager.KEY_AUTHTOKEN).toString();
}
catch (OperationCanceledException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (AuthenticatorException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
return retVal;
}
然后在确保使用正确的 SASL 系统后调用它：
SASLAuthentication.registerSASLMechanism( GTalkOAuth2.NAME, GTalkOAuth2.class );
SASLAuthentication.supportSASLMechanism( GTalkOAuth2.NAME, 0 );
config.setSASLAuthenticationEnabled(true);
String saslAuthString = getAuthToken(acct.name);
connection = new XMPPConnection(config);
try {
connection.connect();
connection.login(name, saslAuthString);
} catch (XMPPException e) {
// Most likely an expired token
// Invalidate the token and start over. There are example of this available
}
快乐谷歌交谈！
