【问题描述】：

我正在尝试使用 smack API 集成 facebook 聊天。但我收到错误消息，提示使用摘要 md5 进行身份验证失败...

这是验证代码：

 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);

下面是我运行它时遇到的错误：

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，但没有成功 vit fb... 可以叫我看看有什么问题吗

【问题讨论】：

嘿任何人都可以提出一个解决方案请...运行超时

【参考方案1】：

对我来说，解决方案是在没有 DNS SRV 的情况下调用 login() 时不要在用户名中包含主机部分，而不是反对 Google Talk 服务。这也是described in the ignite forums.

例如

connection.login("[e-mail]", "password", "resource");

变成

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

【参考方案2】：

Ignite 有一个巨大的线程来处理这个问题。您可能想看看它，因为有几种适用于 Java 和 android 的解决方案似乎可行。

【讨论】：

是的，我尝试了那里给出的所有解决方案，但都没有奏效...在论坛上发布了问题，但没有回复

【参考方案3】：

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

我已经成功使用了这里提供的类

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

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

http://www.facebook.com/username/
