java - 当我尝试连接到服务器时出现“远程服务器超时”异常

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();

我收到一个异常:

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 server穿过防火墙。我也尝试关闭防火墙，但结果相同。服务器是我自己的机器。我尝试在同一台机器上运行该程序。

Answer 1

您可以使用

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

或者如果您想指定端口

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

或类似的，默认端口 5222

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