smack 4.2.0 错误：IN AAAA 产生错误响应 NX_DOMAIN

Question

我启动 openFire 并用 spark 测试一切正常，但是当我尝试在 android studio 中连接 smack 4.2.0 时，我收到了这个错误：

Ljavax/naming/directory/InitialDirContext;

我的依赖项是这样的：

compile "org.igniterealtime.smack:smack-java7:4.2.0" compile "org.igniterealtime.smack:smack-tcp:4.2.0" compile "org.igniterealtime.smack:smack-im:4.2.0" compile "org.igniterealtime.smack:smack-extensions:4.2.0" compile "org.igniterealtime.smack:smack-android-extensions:4.2.0" compile "org.igniterealtime.smack:smack-bosh:4.2.0"

删除时： "compile org.igniterealtime.smack:smack-java7:4.2.0" 从依赖项中添加：编译 "org.igniterealtime.smack:smack-android:4.2.0" 我的依赖关系变成这样：

compile 'com.android.support:appcompat-v7:24.0.0' compile "org.igniterealtime.smack:smack-android:4.2.0" compile "org.igniterealtime.smack:smack-tcp:4.2.0" compile "org.igniterealtime.smack:smack-im:4.2.0" compile "org.igniterealtime.smack:smack-extensions:4.2.0" compile "org.igniterealtime.smack:smack-android-extensions:4.2.0" compile "org.igniterealtime.smack:smack-bosh:4.2.0"

我遇到了这个错误：

org.jivesoftware.smack.SmackException$ConnectionException: The following addresses failed: '192.168.209.2:5222' failed because: de.measite.minidns.hla.ResolutionUnsuccessfulException: Asking for 192.168.209.2. IN A yielded an error response NX_DOMAIN, '192.168.209.2:5222' failed because: de.measite.minidns.hla.ResolutionUnsuccessfulException: Asking for 192.168.209.2. IN AAAA yielded an error response NX_DOMAIN

当我尝试 conn.connect() 时出错的代码部分是这样的：

XMPPTCPConnectionConfiguration config = null;  
            try {  
                config = XMPPTCPConnectionConfiguration.builder()  
                        .setUsernameAndPassword("admin", "thepass")  
                        .setXmppDomain("192.168.1.3")  
                        .setHost("192.168.209.2")  
                        .setPort(5222)  
                        .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)  
                        .build();  
            } catch (Exception e) {  
                e.printStackTrace();  
            }  
                AbstractXMPPConnection conn1 = new XMPPTCPConnection(config);  
                conn1.setReplyTimeout(60000);  
                conn1.setPacketReplyTimeout(60000);  
                conn1.connect();

Answer 1

您遇到的错误是由于您的 XMPP 服务器寻址不完整造成的。

想象一下这个场景：

my ejabberd server is running on this address: 192.168.209.2 #ejabberd server

有一个名为"localhost"的xmpp域，有两个JID，

"davood@localhost" and "sadegh@localhost"

在 smack 中，我想对我的用户进行身份验证，比如 "davood@localhost"。然后我这样做：

            InetAddress addr = InetAddress.getByName("192.168.209.2");
            HostnameVerifier verifier = new HostnameVerifier() {
                @Override
                public boolean verify(String hostname, SSLSession session) {
                    return false;
                }
            };
            DomainBareJid serviceName = JidCreate.domainBareFrom("localhost");
            XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
                    .setHost(server) # it will be resolved by setHostAddress method
                    .setUsernameAndPassword("davood","mypass")
                    .setPort(5222)
                    .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
                    .setXmppDomain(serviceName)
                    .setHostnameVerifier(verifier)
                    .setHostAddress(addr)
                    .setDebuggerEnabled(true)
                    .build();
            AbstractXMPPConnection conn1 = new XMPPTCPConnection(config);

            conn1.connect();

            if(conn1.isConnected()){
                Log.d("XMPP","Connected");
            }
            conn1.login();

            if(conn1.isAuthenticated()){
                Log.d("XMPP","Authenticated");
                EntityBareJid jid = JidCreate.entityBareFrom("sadegh@localhost");
                org.jivesoftware.smack.chat2.Chat chat = ChatManager.getInstanceFor(conn1).chatWith(jid);
                chat.send("Eureka, I am connected!");


            }

请检查： https://github.com/igniterealtime/Smack/wiki/Smack-4.2-Readme-and-Upgrade-Guide

在以前的 Smack 版本中，ConnectionConfiguration.setHost(String) 可用于设置 XMPP 服务的主机 IP 地址。由于添加了 DNSSEC 支持，这不再可能。您必须改用新的连接配置 ConnectionConfiguration.setHostAddress(InetAddress)。

你也可以检查这个。

我在 Kotlin 中遇到了与 Xmpp 连接有些相同的问题，我根据@davood-falahati 的回答实施了一些更改的解决方案，对我来说效果很好：

private fun initializeXmppConnection(){
        val addr: InetAddress = InetAddress.getByName("90.182.109.19")
        val verifier: HostnameVerifier = HostnameVerifier { s, sslSession -> false }
        val serviceName: DomainBareJid = JidCreate.domainBareFrom("im.mydomain.ir")
        val config: XMPPTCPConnectionConfiguration = XMPPTCPConnectionConfiguration.builder()
            .setHost("90.182.109.19")
            .setUsernameAndPassword("60b9d4d75943a","9yqx7heu6aok4g40so8s0w8oocow8w8")
            .setPort(80)
            .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
            .setXmppDomain(serviceName)
            .setHostnameVerifier(verifier)
            .setHostAddress(addr)
            .setSendPresence(true)
            .setCompressionEnabled(false)
            .setConnectTimeout(30_000)
            .build()

        val conn: AbstractXMPPConnection = XMPPTCPConnection(config)
        conn.connect();

        if(conn.isConnected())
            Log.d("msn","Connected");

        conn.login();

        if(conn1.isAuthenticated()){
            Log.d("msn","Authenticated");

        }
    }
