如何从java中的url编码字符串（而不是URL）中获取参数 [英] How to get parameters out of a url encoded string (not a URL) in java

问题描述

我有一个从我正在使用的API返回的url编码字符串。我想在字符串上做一些request.getParameter（paramname）。我正在寻找的是像str.request.getParameter（paramname）。有这样的东西吗？

I have a url encoded string that is returned from an API I am using. I want to do something request.getParameter("paramname") on the string. What I'm looking for is something like str.request.getParameter("paramname"). There's gotta be something like this right?

澄清api返回的内容如下：
name1 = val1& name2 = val2& name3 = val3

clarification the api returns something like: name1=val1&name2=val2&name3=val3

我知道我可以分开&然后浏览每个元素，但这似乎很愚蠢。请指教。谢谢！

I know i could do a split on "&" and then go through each element but that seems stupid. Please advise. Thanks!

推荐答案

使用Apache httpclient库中的URLEncodedUtils。

Use URLEncodedUtils from Apache httpclient library.

API ： http：// hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/client/utils/URLEncodedUtils.html

你会必须调用此方法来获取名称值对：

You will have to call this method to get name value pairs:

static List<NameValuePair>  parse(HttpEntity entity)
          Returns a list of NameValuePairs as parsed from an HttpEntity.
