一个很好的库,用于在Java中执行URL查询字符串操作 [英] A good library to do URL Query String manipulation in Java
问题描述
我需要在Java中进行一些非常简单的URL操作。就像在查询中获取参数的值,或者更新它一样,...我期望在commons-lang包中找到一个简单的实用程序类,但是没有。我知道这是一个简单的问题,但是如果已经写了一些东西,为什么还要这样呢?你知道吗?
I need to do a few very simple URL manipulations in Java. Like get the value for a parameter in the query, or update it, ... I was expecting to find a simple utility class doing that in the commons-lang package, but no. I know it is a simple problem, but if there is something already written, why do it again ? Do you know of any ?
我想至少拥有以下功能:
I would like to have at least the following capabilities :
String myUrl = "http://www.example.com/test.html?toto=1&titi=2";
// get the value of a parameter
String parameterValue = UrlUtils.getParameterValue(myUrl, "toto");
Assert.equals(parameterValue, "1");
// update a parameter
String newUrl = UrlUtils.updateParameter(myUrl, "toto", 3);
parameterValue = UrlUtils.getParameterValue(myUrl, "toto");
Assert.equals(parameterValue, "3");
理想情况下,它会处理所有与编码相关的问题,并使用java.net.Url作为和Strings一样。
Ideally, it would take care of all encoding related issues, and work with java.net.Url as well as with Strings.
感谢您的帮助!
推荐答案
我认为你想要的是一个查询字符串解析器,而不是一个url操纵器,这里是一个: http:/ /ostermiller.org/utils/CGIParser.java.html
I think what you want is called a query string parser instead of an url manipulator and here's one: http://ostermiller.org/utils/CGIParser.java.html
