Question

尝试通过以下代码连接到 openfire 服务器时：

Connection connection = new XMPPConnection("https://192.168.0.101:5222");
connection.connect();

我得到一个例外，说：

https://192.168.0.101:5222:5222 Exception: Could not connect 
to https://192.168.0.101:5222:5222.; : remote-server-timeout(504)

这可能是什么原因？

注意：我已经允许openfire fire服务器通过防火墙。我也试过推迟防火墙，但结果相同.Server是我自己的机器。我正在尝试运行程序的同一台机器。

Answer 1

您可以使用

Connection connection = new XMPPConnection("192.168.0.101");
connection.connect();

或者如果要指定端口

ConnectionConfiguration config = new ConnectionConfiguration("192.168.0.101", 5222);
Connection connection = new XMPPConnection(config);   
connection.connect();

或类似的，默认为端口5222

ConnectionConfiguration config = new ConnectionConfiguration("192.168.0.101");
Connection connection = new XMPPConnection(config);
connection.connect();

Answer 2

试试这个：

Connection connection = new XMPPConnection("localhost:5222");
connection.connect();

Answer 3

您可以参考以下内容：

public XMPPConnection(String serviceName, CallbackHandler callbackHandler) {
    // Create the configuration for this new connection
    super(new ConnectionConfiguration(serviceName));
    config.setCompressionEnabled(false);
    config.setSASLAuthenticationEnabled(true);
    config.setDebuggerEnabled(DEBUG_ENABLED);
    config.setCallbackHandler(callbackHandler);
}

，或者没有用于提示密钥库密码的回调处理程序：

public XMPPConnection(String serviceName) {
    // Create the configuration for this new connection
    super(new ConnectionConfiguration(serviceName));
    config.setCompressionEnabled(false);
    config.setSASLAuthenticationEnabled(true);
    config.setDebuggerEnabled(DEBUG_ENABLED);
}

或：

public XMPPConnection(ConnectionConfiguration config) {
    super(config);
}

我试图连接到服务器时出现'remote-server-timeout'异常
