如何使用apache wicket 1.54获取服务器变量? [英] How can I obtain server variables using apache wicket 1.54?

问题描述

我正在尝试获取运行我的Web应用程序的当前服务器的名称和IP.我不确定该如何执行检票口1.54.我需要知道如何获取服务器变量.

I am trying to get the name and ip of the current server in which my web application is running on. I am not sure how to do this is wicket 1.54. I need to know how to get at my server variables.

在检票口1.4中，您可以执行以下操作:

In wicket 1.4 you could do:

HttpServletRequest hsr = getWebRequestCycle().getWebRequest().getHttpServletRequest();

然后，您可以使用hsr来获取标头或属性.

Then you could use hsr to grab headers or attributes.

在检票口1.54中，等效行是:

In wicket 1.54 the equivalent line is:

HttpServletRequest hsr = (HttpServletRequest)getRequestCycle().getRequest().getContainerRequest();
hsr.getAttribute("SERVER_NAME");

但是我总是得到一个空字符串.

However I always am getting a null string.

推荐答案

这对我在WebPage中使用Wicket 1.5.5有用:

This works for me with Wicket 1.5.5 inside a WebPage:

HttpServletRequest request = (HttpServletRequest) getRequest().getContainerRequest();
String serverName = request.getServerName();
String remoteAddr = request.getRemoteAddr();
