编码和解码rfc2396 URL [英] Encode and Decode rfc2396 URLs

问题描述

对URL字符串进行编码的最佳方法是什么，使它们符合rfc2396并解码符合rfc2396的字符串，例如将％20替换为空格字符？

What is the best way to encode URL strings such that they are rfc2396 compliant and to decode a rfc2396 compliant string such that for example %20 is replaced with a space character?

编辑：
URLEncoder和URLDecoder类执行不编码/解码符合rfc2396的URL，它们编码为MIME类型application / x-www-form-urlencoded，用于编码HTML表单参数数据。

edit: URLEncoder and URLDecoder classes do not encode/decode rfc2396 compliant URLs, they encode to a MIME type of application/x-www-form-urlencoded which is used to encode HTML form parameter data.

推荐答案

使用URI类如下：

URI uri = new URI("http", "//www.someurl.com/has spaces in url", null);
URL url = uri.toURL();

或者如果你想要一个字符串：

or if you want a String:

String urlString = uri.toASCIIString();
