尝试从 aSmack Android 客户端连接到 XMPP 服务器时出现 ConnectionException

问题描述

几个小时以来，我一直在尝试从我的 aSmack Android 客户端连接到我的(本地托管的)Openfire XMPP 服务器，但它仍然无法正常工作.

我得到一个 org.jivesoftware.smack.SmackException$ConnectionException 就是这样.

代码:

public class MainActivity extends Activity {@覆盖protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);SmackAndroid.init(getApplicationContext());连接();}私人布尔连接(){XMPPConnection connection = new XMPPTCPConnection(HOST);尝试{连接.connect();connection.login("user", "user");}catch(异常 e){e.printStackTrace();}返回真；}

服务器已启动并正在运行.

主机是我的服务器名，也试过我的主机名，试过不同的端口...还尝试从另一个线程启动 connect() 方法.尝试使用登录或匿名连接，但在此之前抛出异常，在行:connection.connect();

非常感谢任何帮助.

解决方案

不，不是.如果您查看 javadocConnectionException:

如果 Smack 无法连接到所有，则抛出 ConnectionException给定 XMPP 服务的主机.可以使用以下命令检索失败的主机getFailedAddresses()，这将导致异常连接失败设置和检索HostAddress.getException().

因此调用 ConnectionException.getFailedAddresses() 来检索列表并使用 HostAddress.getException() 检查导致 Smack 无法连接到主机的原因.>

I have been trying to connect to my (locally hosted) Openfire XMPP server from my aSmack Android client for hours now, and it's still not working.

I get a org.jivesoftware.smack.SmackException$ConnectionException and that's it.

Code:

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    SmackAndroid.init(getApplicationContext());
    connect();
}

private boolean connect(){
    XMPPConnection connection = new XMPPTCPConnection(HOST);
    try{
        connection.connect();
        connection.login("user", "user");
    }catch (Exception e){
        e.printStackTrace();
    }
    return true;
}

Server is up and running.

Host is my server name, tried my host name too, tried different ports...Also tried to launch the connect() method from another thread.Tried to use a login or anonymous connection, but Exception is thrown before even that, at line: connection.connect();

Any help highly appreciated.

解决方案

No, it's not. If you look at the javadoc for ConnectionException:

So call ConnectionException.getFailedAddresses() to retrieve the list and check with HostAddress.getException() what caused Smack to be unable to connect to the host.
