Question

我故意复制粘贴this question不要因为重复而生气。在这个主题中有几个不明确的时刻：

1）

xmpp.login(apiKey + "|" + sessionKey, sessionSecret, "Application");

sessionKey是访问令牌的第二部分。如果令牌在这个形式，AAA | BBB | CCC，BBB是会话密钥

但我的访问令牌如下：BAADcfjCWMLABAIyzRSZA69eAtA9Dr3EQVlXA8Ql6rr5odDWxNYZCHhssiaar8S0gaPLZAm1ZBKCqWO3QFegJPR39hT0JR5ZCyIP1AJZC19qh9mFAExUd9KDjJ05yjE3IUZD

所以我看不到任何“第二部分”......

2）

使用旧的REST API和方法获取sessionSecret   auth.promoteSession。要使用它，需要让Http得到它   网址：

https://api.facebook.com/method/auth.promoteSession?access_token=yourAccessToken

尽管Facebook Chat文档说它需要   使用你的应用程序密钥，只有当我使用密钥时   返回REST方法，我能够使它工作。为此   方法有效，您必须禁用禁用不推荐使用的身份验证方法   应用程序设置中“高级”选项卡中的选项。

我已阅读here已弃用REST

我们不会在图谱API中支持此方法。

我该怎么办？我只使用Graph API。有没有其他方法可以获得sessionSecret？

谢谢！

我测试了这个，它对我有用。

首先编辑您的SASLXFacebookPlatformMechanism类。复制并粘贴此代码。

package com.facebook.android;

import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.GregorianCalendar;
import java.util.HashMap;
import java.util.Map;

import org.apache.harmony.javax.security.auth.callback.CallbackHandler;
import org.apache.harmony.javax.security.sasl.Sasl;
import org.jivesoftware.smack.SASLAuthentication;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.sasl.SASLMechanism;
import org.jivesoftware.smack.util.Base64;

import android.util.Log;


public class SASLXFacebookPlatformMechanism extends SASLMechanism {

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

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

        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
    public void authenticate(String username, String host, CallbackHandler cbh) throws IOException, XMPPException {
        String[] mechanisms = { "DIGEST-MD5" };
        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");

            String composedResponse =
                "method=" + URLEncoder.encode(method, "utf-8") +
                        "&nonce=" + URLEncoder.encode(nonce, "utf-8") +
                        "&access_token=" + URLEncoder.encode(accessToken, "utf-8") +
                        "&api_key=" + URLEncoder.encode(apiKey, "utf-8") +
                        "&call_id=0" +
                        "&v=" + URLEncoder.encode(version, "utf-8");
            response = composedResponse.getBytes();
        }

        String authenticationText = "";

        if (response != null) {
            authenticationText = Base64.encodeBytes(response);
        }

        // 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;
    }
}

然后在您想要登录Facebook的活动类中使用此方法。

private void testLogin(){
        ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
        config.setSASLAuthenticationEnabled(true);
        config.setSecurityMode(ConnectionConfiguration.SecurityMode.enabled);
        xmpp = new XMPPConnection(config);
        SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM",SASLXFacebookPlatformMechanism.class);
        SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);
        Log.i("XMPPClient",
                "Access token to " + mFacebook.getAccessToken());
        Log.i("XMPPClient",
                "Access token to " + mFacebook.getAppId());
        Log.i("XMPPClient",
                "Access token to " + mFacebook.getAccessToken());
        try {
            xmpp.connect();
            Log.i("XMPPClient",
                    "Connected to " + xmpp.getHost());

        } catch (XMPPException e1) {
            Log.i("XMPPClient",
                    "Unable to " + xmpp.getHost());

            e1.printStackTrace();
        }
        try {
            xmpp.login(PreferenceConnector.APP_ID, mFacebook.getAccessToken());

            getRoster(xmpp);


        } catch (XMPPException e) {
            e.printStackTrace();
        }  
    }

带有Java Asmack库和X-FACEBOOK-PLATFORM的XMPP
