Openfire不响应Smack登录()

Question

我正在使用Smack，试图连接并登录到Openfire XMPP服务器，它是在我的笔记本电脑(localhost)上安装的。

    XMPPTCPConnectionConfiguration conf = XMPPTCPConnectionConfiguration.builder()
            .setServiceName("win10-xps15")
            .setHost("192.168.1.100")
            .setPort(5222)
            .setCompressionEnabled(false)
            .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
            .build();

    XMPPTCPConnection connection = new XMPPTCPConnection(conf);

    connection.connect();
    connection.login("admin", "password");

connect()方法成功，但NoResponse (超时值)异常导致登录()方法失败。

我在我的Windows笔记本上运行Openfire 3.9.3，本地IP是192.168.1.100。smack库的版本为4.1.6。

因为失败的是login()方法，所以我想知道是否有任何与登录/用户相关的Openfire服务器设置是我应该知道的？

此外，我尝试用火花IM客户端登录，它可以毫无问题地登录本地服务器。

致以问候。

更多的信息添加到下面。

我刚刚尝试了从火花IM github回购获得的一个旧版本的smack (3.4.1)，代码如下：

    ConnectionConfiguration conf = 
            new ConnectionConfiguration("192.168.1.100", 5222);
    XMPPConnection connection = new XMPPConnection(conf);

    connection.connect();
    connection.login("admin", "password");

现在代码工作正常。connect()和login()都正常。

但是我真的想知道为什么最近版本的smack不能像我预期的那样工作。因为我考虑在Android上使用smack，而旧版本不支持Android。

Answer 1

让我们从一步一步开始

1)添加依赖项

compile 'org.igniterealtime.smack:smack-tcp:4.1.0'
compile 'org.igniterealtime.smack:smack-android-extensions:4.1.0'
compile 'org.igniterealtime.smack:smack-im:4.1.0'

2)连接或登录到服务器的异步任务

//connect or login to server
private class MyOpenfireLoginTask extends AsyncTask<String, String, String> {
    private Context mContext;
    String username, password;
    ProgressDialog dialog;


    public MyOpenfireLoginTask(Context context) {
        mContext = context;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        dialog = new ProgressDialog(mContext);
        dialog.setMessage("Loading...");
        dialog.setCanceledOnTouchOutside(false);
        dialog.show();
    }

    @Override
    protected String doInBackground(String... params) {

        username = params[0];
        password = params[1];

        Log.e("Login using ", username + " , " + password);
        Config.config = XMPPTCPConnectionConfiguration.builder()
                .setUsernameAndPassword(username, password)
                .setHost("your host ex- wec.com")
                .setResource("Android")
                .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
                .setServiceName("domain name(@) ex-   secureserver.net")
                .setPort("5222")
                .setDebuggerEnabled(true)
                .build();
        Config.conn1 = new XMPPTCPConnection(Config.config);

        Config.conn1.setPacketReplyTimeout(5000);
        try {
            Config.conn1.connect();
            if (Config.conn1.isConnected()) {
                Log.w("app", "conn done");

            }
            Config.conn1.login();


            if (Config.conn1.isAuthenticated()) {
                Log.w("app", "Auth done");

            } else {
                Log.e("User Not Authenticated", "Needs to Update Password");

            }

        } catch (Exception e) {
            Log.w("app", e.toString());
        }

        return "";
    }

    @Override
    protected void onPostExecute(String result) {


        dialog.dismiss();

        if (Config.conn1.isAuthenticated()) {
             //success

        } else {
            Log.e(TAG, "username password wrong");

        }
    }
}

3)执行上述类

  if (username.length() > 0 && password.length() > 0) {
        MyOpenfireLoginTask task = new MyOpenfireLoginTask(activity);
        task.execute(username, password);
    }
