如何获取 servlet 所在的主机名(带端口) [英] How can I get a the host name (with port) that a servlet is at

问题描述

我认为 ServletContext 可能提供了一种方法.ServletContext 的 getAttribute() 方法是否提供任何帮助，即是否有一个有用的属性名称(可能是主机"、端口").

I thought ServletContext might provide a method. Does the getAttribute() method of ServletContext provide any help i.e. is there an attribute name (maybe "host", "port") that will be of help.

这样做的原因是我希望我的应用程序可以在部署的任何地方运行，并且有一次我必须允许用户单击指向文件服务器上某个位置的链接.因此我需要通过主机和端口引用，不能使用内部引用.

The reason for this is I want my application to run wherever it is deployed, and at one point I have to allow a user to click a link that points to a location on the file server. Hence I need to reference by the host and port and cannot use an internal reference.

推荐答案

ServletRequest.getServerName(...)
ServletRequest.getServerPort(...)
