java - Smack 和 SASL 身份验证错误 - 没有已知的身份验证机制

Question

我正在尝试使用最新版本的 Smack 4.1.0-beta 创建 XMPP 客户端。但是我在尝试登录到本地运行的 OpenFire 服务器时遇到错误。

org.jivesoftware.smack.SmackException: SASL Authentication failed. No known authentication mechanisims.

我尝试了各种用户凭据组合，但到目前为止都没有成功。当尝试使用 Pidgin 或 Adium al 连接到服务器时是可以的。知道我在代码中遗漏了什么吗？

XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
            .setUsernameAndPassword("admin", "admin")
            .setServiceName("localhost")
            .setHost("localhost")
            .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
            .setPort(5222)
            .build();

    AbstractXMPPConnection connection = new XMPPTCPConnection(config);

    try {

        connection.connect();

        connection.login();

        connection.disconnect();

    } catch (SmackException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (XMPPException e) {
        e.printStackTrace();
    }

这是完整的解决方案，请仔细阅读...

            return null;
        }

}

更新:- 对于 smack 4.2.0-beta2 版本，使用下面的代码为 PLAIN 配置 XmppConnection身份验证。

XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();
builder.setHost("example.com");
builder.setPort(5222);
/*builder.setServiceName("example.com");*/ //for older version < 4.2.0-beta2
try
{
    builder.setXmppDomain(JidCreate.domainBareFrom("example.com"));
}
catch (XmppStringprepException e)
{
    e.printStackTrace();
}
/*builder.setServiceName("example.com");*/
builder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
builder.setCompressionEnabled(true);
builder.setConnectTimeout(30000);
/*builder.setSendPresence(false);*/
try
{
    TLSUtils.acceptAllCertificates(builder);
}
catch (NoSuchAlgorithmException|KeyManagementException e)
{
    e.printStackTrace();
}
TLSUtils.disableHostnameVerificationForTlsCertificates(builder);
final Map<String, String> registeredSASLMechanisms = SASLAuthentication.getRegisterdSASLMechanisms();
for(String mechanism:registeredSASLMechanisms.values())
{
    SASLAuthentication.blacklistSASLMechanism(mechanism);
}
SASLAuthentication.unBlacklistSASLMechanism(SASLPlainMechanism.NAME);

xmppConnection=new XMPPTCPConnection(builder.build());
