Question

我遇到了这个问题，我无法解决。

代码：

 ConnectionConfiguration config = new ConnectionConfiguration(host, port);
        config.setDebuggerEnabled(true);
        config.setSASLAuthenticationEnabled(true);
        config.setSecurityMode(ConnectionConfiguration.SecurityMode.enabled);

        XMPPConnection connection = new XMPPConnection(config);
try{
            connection.connect();
            connection.login(login, password);
            //auth.authenticate(login, password, host);
        }
        catch (XMPPException exc){
            exc.printStackTrace();
        }

Answer 1

Smack库（3.2.2）期望第二个（在starttls之后）“stream：stream”数据包中的@id属性。

此属性是可选的，xmpp.odnoklassnki.ru不会发送它：

<stream:stream to="odnoklassniki.ru" xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams" version="1.0">

有两种方法可以解决这个问题：

要么修补PacketReader，要为流中没有@id属性的连接分配某种“假”ID：stream packet
或者请xmpp.odnoklassniki.ru的管理员/开发人员向流添加（虚假或真实）ID属性：stream packet

这是PacketReader的一部分“修补”：parsePackets（）方法。请注意新的connectionIdReceived变量和对应的“if”条件：

// We found an opening stream. Record information about it, then notify
// the connectionID lock so that the packet reader startup can finish.
else if (parser.getName().equals("stream")) {
    // Ensure the correct jabber:client namespace is being used.
    if ("jabber:client".equals(parser.getNamespace(null))) {
        // Get the connection id.
        boolean connectionIdReceived = false;
        for (int i=0; i<parser.getAttributeCount(); i++) {
            if (parser.getAttributeName(i).equals("id")) {
                // Save the connectionID
                connectionID = parser.getAttributeValue(i);
                if (!"1.0".equals(parser.getAttributeValue("", "version"))) {
                    // Notify that a stream has been opened if the
                    // server is not XMPP 1.0 compliant otherwise make the
                    // notification after TLS has been negotiated or if TLS
                    // is not supported
                    releaseConnectionIDLock();
                }
                connectionIdReceived = true;
            }
            else if (parser.getAttributeName(i).equals("from")) {
                // Use the server name that the server says that it is.
                connection.config.setServiceName(parser.getAttributeValue(i));
            }
        }
        if (!connectionIdReceived) {
            connectionID = "<unspecified>";
            if (!"1.0".equals(parser.getAttributeValue("", "version"))) {
                // Notify that a stream has been opened if the
                // server is not XMPP 1.0 compliant otherwise make the
                // notification after TLS has been negotiated or if TLS
                // is not supported
                releaseConnectionIDLock();
            }
        }
    }
}

Answer 2

我看到了几种可能性：

由于信任链或服务器提供的* -name，您的图书馆不接受您从服务器获得的证书：

主题：C = RU，L =莫斯科，O = Odnoklassniki有限公司，CN = * .odnoklassniki.ru

在“安全”模式下，您的库不喜欢该服务器提供的任何auth机制，因为只有两种非标准机制（X-ODKL-API，X-ODKL-BLOWFISH）和两个不太安全的机制（PLAIN，http://jabber.org/features/iq-auth）。

如果我不得不猜测它会是第二个。这不是大多数客户端库作者不太可能遇到的错误情况。关闭安全模式，然后重试。

Answer 3

你的XMPP域似乎有误，这也可能是问题所在。并且您还将两个流标头发送到不同的域：

标题1到 xmpp.odnoklassniki.ru ：

<stream:stream to="xmpp.odnoklassniki.ru" xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams" version="1.0">

标题2 odnoklassniki.ru ：

<stream:stream to="odnoklassniki.ru" xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams" version="1.0">

服务器总是回复....来自=“odnoklassniki.ru”.... 所以 odnoklassniki.ru 应该是您正确的XMPP域名。

Answer 4

试试这个......

它对我有用...尝试给出资源名称...我面临同样的问题gioving资源名称解决了它

 ConnectionConfiguration config;
config = new ConnectionConfiguration(ip, port, "Smack");
config.setSASLAuthenticationEnabled(false);
config.setReconnectionAllowed(true);
config.setCompressionEnabled(false);
config.setDebuggerEnabled(true);
connection = new XMPPConnection(config);
connection.connect();
if (connection.isConnected()) {
    connection.login(loginName, password);
}

无法通过smack连接到XMPP服务器：服务器没有响应
