使用 Smack 集成 Facebook 聊天时 SASL 身份验证失败

Question

我正在尝试使用 smack API 集成 facebook 聊天。但是我收到一条错误消息，告诉我使用摘要 md5 身份验证失败...

这是身份验证代码：

 SASLAuthentication.registerSASLMechanism("DIGEST-MD5", SASLDigestMD5Mechanism.class);
  SASLAuthentication.supportSASLMechanism("DIGEST-MD5", 0);

    ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com",5222);
    connection = new XMPPConnection(config);
    config.setSASLAuthenticationEnabled(true);
    connection.connect();
    connection.login(userName, password);

下面是我运行它时收到的错误：

Exception in thread "main" SASL authentication failed using mechanism DIGEST-MD5: 
    at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:325)
    at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:395)
    at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:349)
    at JabberSmackAPIFacebook.login(JabberSmackAPIFacebook.java:31)
    at JabberSmackAPIFacebook.main(JabberSmackAPIFacebook.java:77)

我可以成功连接到 gtalk，但是我没有成功 vit fb... 苏莫能告诉我问题是什么吗

Answer 1

对我来说，解决方案是在不使用 DNS SRV 且不使用 Google Talk 服务的情况下调用 login() 时不在用户名中包含主机部分。这也在 ignite 论坛中进行了描述。

例如

connection.login("[email protected]", "password", "resource");

变成

connection.login("user", "password", "resource");

Answer 2

Ignite 上有一个巨大的线程处理这个问题。您可能想看看它，因为有几种针对 Java 和 Android 的解决方案似乎可行。

Answer 3

我已经使用 DIGEST-MD5 成功连接到 facebook，您发布的代码看起来不错。
但我们仍然需要检查您的 SASLDigestMD5Mechanism 类的内容

我已成功使用此处提供的类

http ://community.igniterealtime.org/message/200878#200878

另外，您还必须注意，在 DIGEST-MD5 机制中，您必须使用您的 facebook 用户名登录，而不是使用电子邮件登录地址。默认情况下，Facebook 帐户没有用户名，您必须先创建一个用户名，您可以在此处查看：

http://www.facebook.com/用户名/
