如何使用Servlet从请求中获取上一页URL [英] How to get previous page URL from request using a servlet

问题描述

如何使用servlet从请求中获取上一页URL.例如，我来自index.html，并且我提交了来自index的表单，如何获取index.html URL并在servlet中使用它?

How do I get the previous page URL from request using a servlet. For example, I'm from the index.html and I submitted a form from index, how do I get the index.html URL and use it in a servlet?

request.getRequestURL()

getRequestURL不起作用，因为它仅返回servlet的URL.

getRequestURL doesn't work since it only returns the URL of the servlet.

推荐答案

在Servlet中编写以下代码

Write in your Servlet the following code

字符串url = request.getHeader("referer");

String url = request.getHeader("referer");

这对我来说很有效.希望它也对您有用

This worked in my case.Hope it works for you as well
