与连接至Facebook XMMP MD5，DIGEST问题 [英] Problems with connecting to Facebook XMMP MD5-DIGEST
问题描述
我已经尝试了所有的东西与XMPP连接的Facebook，但我只有面对
这是一次错误的所有时间：
使用机制，DIGEST-MD5
我采取下面的方法来执行此任务SASL验证失败：
I have tried all the things to connect Facebook with XMPP but i have faced only
one error all the time which is :
SASL authentication failed using mechanism DIGEST-MD5
I am implementing following method to perform this task :
public class MySASLDigestMD5Mechanism extends SASLMechanism {
public MySASLDigestMD5Mechanism(SASLAuthentication saslAuthentication) {
super(saslAuthentication);
}
protected void authenticate() throws IOException, XMPPException {
String[] mechanisms = { getName() };
Map<String, String> props = new HashMap<String, String>();
sc = Sasl.createSaslClient(mechanisms, null, "xmpp", hostname, props, this);
super.authenticate();
}
public void authenticate(String username, String host, String password) throws IOException, XMPPException {
this.authenticationId = username;
this.password = password;
this.hostname = host;
String[] mechanisms = { getName() };
Map<String,String> props = new HashMap<String,String>();
sc = Sasl.createSaslClient(mechanisms, null, "xmpp", host, props, this);
super.authenticate();
}
public void authenticate(String username, String host, CallbackHandler cbh) throws IOException, XMPPException {
String[] mechanisms = { getName() };
Map<String,String> props = new HashMap<String,String>();
sc = Sasl.createSaslClient(mechanisms, null, "xmpp", host, props, (org.apache.harmony.javax.security.auth.callback.CallbackHandler) cbh);
super.authenticate();
}
protected String getName() {
return "DIGEST-MD5";
}
/*public void challengeReceived1(String challenge) throws IOException {
// Build the challenge response stanza encoding the response text
StringBuilder stanza = new StringBuilder();
byte response[];
if (challenge != null) {
response = sc.evaluateChallenge(Base64.decode(challenge));
} else {
response = sc.evaluateChallenge(null);
}
String authenticationText="";
if (response != null) { // fix from 3.1.1
authenticationText = Base64.encodeBytes(response, Base64.DONT_BREAK_LINES);
if (authenticationText.equals("")) {
authenticationText = "=";
}
}
stanza.append("<response xmlns=\"urn:ietf:params:xml:ns:xmpp-sasl\">");
stanza.append(authenticationText);
stanza.append("</response>");
// Send the authentication to the server
getSASLAuthentication().send(stanza.toString());
}*/
public void challengeReceived(String challenge)
throws IOException {
byte response[];
if (challenge != null) {
response = sc.evaluateChallenge(Base64.decode(challenge));
} else {
response = sc.evaluateChallenge(new byte[0]);
}
Packet responseStanza;
if (response == null) {
responseStanza = new Response();
} else {
responseStanza = new Response(Base64.encodeBytes(response, Base64.DONT_BREAK_LINES));
}
getSASLAuthentication().send(responseStanza);
}
}
和连接功能是：
try{
SASLAuthentication.registerSASLMechanism("DIGEST-MD5",MySASLDigestMD5Mechanism. class);
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com",5222);
config.setSASLAuthenticationEnabled(true);
config.setRosterLoadedAtLogin (true);
connection = new XMPPConnection(config);
connection.connect();
Log.d("Connect...", "Afetr Connect");
connection.login("username@chat.facebook.com", "password");
Log.d("done","XMPP client logged in");
}
catch(XMPPException ex)
{
Log.d("not done","in catchhhhhhhhh");
System.out.println(ex.getMessage ());
connection.disconnect();
}
}
but "After connect" it gone to the ctach and give me error like :
SASL authentication failed using mechanism DIGEST-MD5
我找遍了所有的博客，发现同样的事情，但我不知道我在做什么错在这里。
I searched all blog and find same thing but i dont know what am i doing wrong here..
如果有连接Facebook的XMPP其他任何方式或解决方案，那么请帮助我 尽快
If is there any other way or solution to connect Facebook XMPP then please Help me ASAP
推荐答案
最后，感谢no.good.at.coding code和harism的建议，我已经能够连接到Facebook的聊天。这code是Asmack库（该端口啪为Android）的机制。为的Smack库是必需使用no.good.at.coding机制
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.

要使用它：
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是在应用程序的设置页面中Facebook给出的API密钥。 sessionKey是接入令牌的第二部分。如果令牌在这种形式下，AAA | BBB | CCC，血脑屏障是会话密钥。 sessionSecret是使用与方法auth.promoteSession旧REST API获得。要使用它，它需要做出一个HTTP GET这个网址：
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:
<一个href="https://api.facebook.com/method/auth.promoteSession?access_token=yourAccessToken">https://api.facebook.com/method/auth.promoteSession?access_token=yourAccessToken
尽管Facebook的聊天文件说，这是需要使用你的应用程序的密钥，只有当我使用的返回REST方法我可以使它工作的关键。为了使该方法的工作，你必须在你的应用程序设置禁用在高级选项卡禁用德precated验证方法的选择。
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.
