连接到ejabberd服务器时出现未知主机异常。

public static final String HOST = "http://54.254.220.129:5280/admin";
public static final int PORT = 5222;
public static final String SERVICE = "localhost";
public static final String USERNAME = "admin@localhost";
public static final String PASSWORD = "########";



ConnectionConfiguration connConfig = new ConnectionConfiguration(HOST, PORT, SERVICE);
XMPPConnection connection = new XMPPConnection(connConfig);
enter code here
            try {
                connection.connect();
                Log.i("XMPPChatDemoActivity",
                        "[SettingsDialog] Connected to "
                                + connection.getHost());
            } catch (XMPPException ex) {
                Log.e("XMPPChatDemoActivity",
                        "[SettingsDialog] Failed to connect to "
                                + connection.getHost());
                Log.e("XMPPChatDemoActivity", ex.toString());
                setConnection(null);
            }

任何答案都会很明显！感谢

Answer 1

传统XMPP不使用HTTP

您无法连接到http://54.254.220.129:5280/admin（这适用于浏览器！）

您只需要使用IP地址

public static final String HOST = "54.254.220.129";

Answer 2

在您的HOST字符串中，您已经编写了端口号。所以我认为你只需要编写没有端口的ip地址和像http://54.254.220.129这样的管理员。 - 之后尝试连接。并尝试登录。

试试这个;

public static final String HOST = "http://54.254.220.129";
public static final int PORT = 5222;
public static final String SERVICE = "localhost";
public static final String USERNAME = "admin@localhost";
public static final String PASSWORD = "########";

ConnectionConfiguration connConfig = new ConnectionConfiguration(HOST, PORT, SERVICE);
XMPPConnection connection = new XMPPConnection(connConfig);

connection.connect();
connection.login(USERNAME, PASSWORD);
