我搜索了许多地方,想方设法将Facebook聊天功能整合到Android / Smack中,但没有一个完全有效。有人可以提供适用于最新版本API的实用示例吗?

使用 X-FACEBOOK-PLATFORM SASLAuthentication进行身份验证。已于2014年1月14日通过Android 4.2.2验证工作。
jabber ID not username@chat.facebook.com。它被解析为一个数字ID,你可以检查名册。
<强> ChatActivity.java
public void connectToFb() throws XMPPException {
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM",SASLXFacebookPlatformMechanism.class);
SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);
config.setSASLAuthenticationEnabled(true);
config.setSecurityMode(SecurityMode.required);
config.setSendPresence(false);
XMPPConnection xmpp = new XMPPConnection(config);
try {
xmpp.connect();
xmpp.login(Session.getActiveSession().getApplicationId(), Session.getActiveSession().getAccessToken(), "Application");
//send a chat message
ChatManager chatmanager = xmpp.getChatManager();
Chat newChat = chatmanager.createChat("<jabber-id-here>@chat.facebook.com", new MessageListener() {
@Override
public void processMessage(Chat chat, Message msg) {
Log.d("test", "message sent = "+ msg);
}
});
newChat.sendMessage("Cowdy!");
//get roster
Roster roster = xmpp.getRoster();
Collection<RosterEntry> entries = roster.getEntries();
System.out.println("Connected!");
System.out.println("\n\n" + entries.size() + " buddy(ies):");
for (RosterEntry entry : entries) {
Log.i("test", entry.getName());
Log.i("test", entry.getUser());
}
} catch (XMPPException e) {
xmpp.disconnect();
e.printStackTrace();
}
}
<强> SASLXFacebookPlatformMechanism.java
public class SASLXFacebookPlatformMechanism extends SASLMechanism {
public static final String NAME = "X-FACEBOOK-PLATFORM";
private String apiKey = "";
private String accessToken = "";
/**
* Constructor.
*/
public SASLXFacebookPlatformMechanism(SASLAuthentication saslAuthentication) {
super(saslAuthentication);
}
@Override
protected void authenticate() throws IOException, XMPPException {
// Send the authentication to the server
getSASLAuthentication().send(new AuthMechanism(getName(), ""));
}
@Override
public void authenticate(String apiKey, String host, String accessToken) throws IOException, XMPPException {
this.apiKey = apiKey;
this.accessToken = accessToken;
this.hostname = host;
String[] mechanisms = { "DIGEST-MD5" };
Map<String, String> props = new HashMap<String, String>();
this.sc = Sasl.createSaslClient(mechanisms, null, "xmpp", host, props, this);
authenticate();
}
@Override
protected String getName() {
return NAME;
}
@Override
public void challengeReceived(String challenge) throws IOException {
byte[] response = null;
if (challenge != null) {
String decodedChallenge = new String(Base64.decode(challenge));
Map<String, String> parameters = getQueryMap(decodedChallenge);
String version = "1.0";
String nonce = parameters.get("nonce");
String method = parameters.get("method");
long callId = new GregorianCalendar().getTimeInMillis() / 1000L;
String composedResponse = "api_key=" + URLEncoder.encode(apiKey, "utf-8")
+ "&call_id=" + callId
+ "&method=" + URLEncoder.encode(method, "utf-8")
+ "&nonce=" + URLEncoder.encode(nonce, "utf-8")
+ "&access_token=" + URLEncoder.encode(accessToken, "utf-8")
+ "&v=" + URLEncoder.encode(version, "utf-8");
response = composedResponse.getBytes("utf-8");
}
String authenticationText = "";
if (response != null){
authenticationText = 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;
}
}
使用SASL / Plain的身份验证流程(提供用户名和密码时)
