Smack facebook登录未经授权

Question

我完全坚持在我的Android应用程序中实现Facebook聊天。我正在使用aSmack库提供的XMPP连接。一切正常，如果我使用PLAIN机制和我的常规Facebook用户名和密码，就像这样

SASLAuthentication.supportSASLMechanism("PLAIN"); xmpp.login("my_username@mail.com", "my_password");

但如果我使用X-FACEBOOK-PLATFORM机制登录我的应用程序ID和访问令牌，那么我总是得不到authrized错误。

这是我的主要登录方式：

public void testLogin(){
        SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM", SASLXFacebookPlatformMechanism.class);
        SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);
        ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com",5222);
        config.setSASLAuthenticationEnabled(true);
        config.setSecurityMode(ConnectionConfiguration.SecurityMode.enabled);

        XMPPConnection xmpp = new XMPPConnection(config);

        try {
            //Async connecting to XMPPConnection
            new ConnectXMPP().execute(xmpp).get();

            Log.i("XMPPClient",
                    "Connected to " + xmpp.getHost());

        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }
        try {
            SmackConfiguration.setPacketReplyTimeout(1500);

            xmpp.login("145537185371985731", "145537185371985731|W3-5DTut4qFoNuBapOI-f5Bo_eQ", "Application");

            Log.i("10201970684380516", "Logged in to " + xmpp.getHost());
        } catch (XMPPException e) {
            e.printStackTrace();
        }
    }

这是我的SASLXFacebookPlatformMechanism类

public class SASLXFacebookPlatformMechanism extends SASLMechanism {

    private static final String NAME = "X-FACEBOOK-PLATFORM";

    private String apiKey = "";
    private String access_token = "";

    /**
     * Constructor.
     */
    public SASLXFacebookPlatformMechanism(SASLAuthentication saslAuthentication) {
        super(saslAuthentication);
    }

    @Override
    protected void authenticate() throws IOException, XMPPException {

        getSASLAuthentication().send(new AuthMechanism(NAME, ""));
    }

    @Override
    public void authenticate(String apiKey, String host, String acces_token)
            throws IOException, XMPPException {
        if (apiKey == null || acces_token == null) {
            throw new IllegalArgumentException("Invalid parameters");
        }

        this.access_token = acces_token;
        this.apiKey = apiKey;
        this.hostname = host;

        String[] mechanisms = { NAME };
        Map<String, String> props = new HashMap<String, String>();
        this.sc = Sasl.createSaslClient(mechanisms, null, "xmpp", host, props,
                this);
        authenticate();
    }

    @Override
    public void authenticate(String username, String host, CallbackHandler cbh)
            throws IOException, XMPPException {
        String[] mechanisms = { NAME };
        Map<String, String> props = new HashMap<String, String>();
        this.sc = Sasl.createSaslClient(mechanisms, null, "xmpp", host, props,
                cbh);
        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();

            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(access_token, "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;
    }
}

我总是遇到异常。
