Question

我正在尝试使用smack API集成Facebook聊天。但是我在使用摘要md5时收到错误告知身份验证失败...

这是验证码：

 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);

下面是我运行它时出现的错误：

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但是没有成功的vit fb ... 可以告诉我这个问题

Answer 1

对我而言，解决方案是在没有DNS SRV的情况下调用login()而不是Google Talk服务时，不包括用户名中的主机部分。这也是described in the ignite forums.

E.g。

connection.login("user@jabber.org", "password", "resource");

变为

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

Answer 2

Ignite有一个巨大的主题可以处理这个问题。您可能希望看一下它，因为有几种解决方案可供Java和Android使用。

Answer 3

我已成功使用DIGEST-MD5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SASLDigestMD5Mechanism类的内容

我已使用此处提供的课程成功

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

此外，您必须注意，在DIGEST-MD5机制中，您必须使用 facebook用户名登录，而不是使用电子邮件地址登录。默认情况下，Facebook帐户没有用户名，你必须创建一个fisrt，你可以在这里检查：

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