【问题描述】：

我正在使用 android 的 Smack 4.1 本机库来开发聊天应用程序。我能够在我的应用程序和我的服务器之间设置连接，但是我在登录时收到有关 SASL 身份验证的 SmackException。

注意事项。

我的服务器端不需要 SASL 身份验证。 我的应用程序没有崩溃，但出现了以下错误，我在下面的日志 cat 片段中显示了这些错误。

我使用的是 eclipse Luna 和 JDK 1.7 版，我在 libs 文件夹中包含了以下库。

jxmpp-core-0.4.1 jxmpp-util-cache-0.4.1 minidns-0.1.1 smack-android-4.1.0.jar smack-android-extensions-4.1.0 smack-core-4.1.0 smack-extensions-4.1.0 smack-im-4.1.0 smack-tcp-4.1.0

这是我用来建立连接的代码。

XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
        configBuilder.setUsernameAndPassword(userName, pass);
        configBuilder.setSecurityMode(XMPPTCPConnectionConfiguration.SecurityMode.disabled);
        configBuilder.setResource("testServices");
        configBuilder.setServiceName(DOMAIN);
        configBuilder.setPort(PORT);
        configBuilder.setHost(DOMAIN);
        configBuilder.setDebuggerEnabled(true);

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

        /** Connecting to the server */
        try 
            connection.connect();
            Log.i(TAG, "Connected to " + connection.getHost());
         catch (SmackException e) 
            e.printStackTrace();
         catch (IOException e) 
            e.printStackTrace();
         catch (XMPPException e) 
            Log.e(TAG, "Failed to connect to " + connection.getHost());
            Log.e(TAG, e.toString());
            e.printStackTrace();
        

        /** LogingIn to the server */
        try 

            //SASLMechanism.PLAIN();
            //SASLAuthentication.("PLAIN", 0);

            connection.login(userName, pass);
            // connection.login();
         catch (XMPPException e) 
            e.printStackTrace();
         catch (SmackException e) 
            e.printStackTrace();
         catch (IOException e) 
            e.printStackTrace();
        

        /** LogingOut from the server */
        connection.disconnect();

这是我的 logcat 输出。

提前感谢您的帮助。 干杯:)

【参考方案1】：

经过一番苦苦挣扎，我终于找到了解决问题的方法。

我必须导入 smack-sasl-provided-4.1.0.jar 以消除此 SASLAuthentication 错误。

你能详细描述一下你的答案吗？ @Taimur Khan
