使用asmack在Android上使用新的访问令牌的Facebook聊天 [英] facebook chat using asmack on android with the new access token

问题描述

我已经为Android开发的FB聊天客户端。我一直在使用Facebook的Andr​​oid的SDK，以获得用户的访问令牌。使用asmack，用户登录到聊天。令牌形式：226409362971500 | 3b29bc82baa7901a9baca042.4-72793766 | 9eb417f06fc376897222938295a0dd0c的code我用的是：

I have a FB chat client developed for Android. I've been using facebook android-sdk to obtain the access token from a user. Using asmack, user was logged into the chat. Token was in the form: 226409362971500|3b29bc82baa7901a9baca042.4-72793766|9eb417f06fc376897222938295a0dd0c The code I used was:

XMPPConnection xmpp = new XMPPConnection(config);
SASLAuthentication.registerSASLMechanism("DIGEST-MD5", SASLDigestMD5Mechanism.class);
SASLAuthentication.supportSASLMechanism("DIGEST-MD5", 0);
xmpp.connect();
xmpp.login("226409362971500", "3b29bc82baa7901a9fbaca042.4-72793766|9eb417f06fc376897222938295a0dd0c", "Application");

现在看来，Facebook已经改变了令牌格式。我曾尝试与旧令牌登录，但我总是得到XMPPException。我试着登录与新的访问令牌：

Now it seems that Facebook has changed the token format. I have tried logging in with the old token, but I always get XMPPException. I've tried logging in with the new access token:

xmpp.login（令牌，应用程序），
但仍没有运气。 不知道如何解决这个问题？

xmpp.login(token, "Application"),
but still no luck. Any idea how to solve this?

推荐答案

在一点上的官方FB文档真的很好），我来到了一个如下结论：
 1. XMPP连接必须使用SSL
 在响应2， session_key可以必须替换为 access_token

After a bit of research (php example on the official FB documentation is really good), I came to a following conclusion:
1. xmpp connection must use ssl
2. in a response, session_key must be replaced with access_token

在短期：

ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
config.setSASLAuthenticationEnabled(true);
config.setSecurityMode(ConnectionConfiguration.SecurityMode.enabled);
XMPPConnection xmpp = new XMPPConnection(config);
SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM",SASLXFacebookPlatformMechanism.class);
SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);
xmpp.connect();
xmpp.login(appSecret, accessToken, "Application");    

SASLXFacebookPlatformMechanism 是我班从 org.jivesoftware.smack.sasl.SASLMechanism
