如何使用 Smack 4.2 连接到 ejabberd？

Question

我已更改我的应用程序以使用 Smack 4.2 替换 Smack 4.1

但我在 config.setServiceName();

中遇到错误

此方法的参数已从 String 更改为 DomainBareJid。我不知道如何在这个新的 Smack 中使用 DomainBareJid 和 setServiceName。

XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration
                .builder();
        config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);


        config.setServiceName("What should i put here?");


        config.setHost(serverAddress);
        config.setPort(5222);
        config.setDebuggerEnabled(true);
        connection = new XMPPTCPConnection(config.build());

        connection.setUseStreamManagement(true);

如果我不设置服务名称，则会出现以下错误：

请提供一些设置服务名称的示例代码以提供帮助。

Answer 1

服务名称应该是您提供服务的主机名。例如：

config.setServiceName("gtalk.com");

Answer 2

DomainBareJid serviceName = JidCreate.domainBareFrom("example.org");
config.setServiceName(serviceName);

Answer 3

这是我的连接代码，效果很好。

    DomainBareJid domainBareJid = JidCreate.domainBareFrom(mServiceName) ;
    XMPPTCPConnectionConfiguration.Builder builder=
            XMPPTCPConnectionConfiguration.builder();
    builder.setServiceName(domainBareJid);
    builder.setHostAddress(InetAddress.getByName(mServiceName));
    builder.setUsernameAndPassword(mUsername, mPassword);
     builder.setResource("resource");
    builder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);

    mConnection = new XMPPTCPConnection(builder.build());
    mConnection.addConnectionListener(this);
    mConnection.connect();
    mConnection.login();

Answer 4

        DomainBareJid serviceName = null;
        try
        {
            serviceName = JidCreate.domainBareFrom("yourdomain.com");
        }
        catch (XmppStringprepException e)
        {
            e.printStackTrace();
        }

XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
                .setUsernameAndPassword("1234567890@test", "123")
                .setHost("yourhostname.com")
                .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
                //.setSendPresence(true)
                .setXmppDomain(serviceName)
                .setPort(5222)
                .setDebuggerEnabled(true) // to view what's happening in detail
                .build();

        conn = new XMPPTCPConnection(config);

我已经测试过了并且工作正常。

Answer 5

这是使用 Smack 4.4 的方法

   XMPPTCPConnectionConfiguration conf = XMPPTCPConnectionConfiguration.builder()
            .setHostAddress(InetAddress.getByName(host))
            .setXmppDomain(JidCreate.domainBareFrom(Domain))
            .setUsernameAndPassword("username", "password")
            .setPort(5222)
            .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
            .build();
    AbstractXMPPConnection connection = new XMPPTCPConnection(conf);
    connection.connect();
    connection.login();
