Smack 4.1.7的XMPPBOSHConnection失败了吗？

Question

我们遇到此配置问题，通过http-bind连接到xmpp服务器。

        BOSHConfiguration.Builder configBuilder =   BOSHConfiguration.builder();
        configBuilder.setUsernameAndPassword("user", "pass");
        configBuilder.setHost("host.ltd");
        configBuilder.setPort(port);
        configBuilder.setFile("/http-bind/");
        configBuilder.setUseHttps(false);
        configBuilder.setServiceName("domain.ltd");

        Bytestream stream = new Bytestream();
        stream.setSessionID("123");
        configBuilder.setResource(stream.toXML().toString());



        AbstractXMPPConnection connection = new XMPPBOSHConnection(configBuilder.build());

        try {
            connection.connect();
            Log.e("alert", "connected");
        } catch (SmackException | IOException | XMPPException e) {
            // TODO Auto-generated catch block
            Log.e("alert", "problem : "+e);
            e.printStackTrace();
        }

我们尝试不用

        Bytestream stream = new Bytestream();
        stream.setSessionID("123");
        configBuilder.setResource(stream.toXML().toString());

但仍未连接到服务器。

我们用pidgin检查服务器连接，其他bosh连接正常工作
