开发时有时服务端返回的json中包含url，url中可能含有一些特殊字符，这些特殊字符在传输的过程中可能会被转义成编码。这时候我们拿到手里要如何转换回去呢，先看下那些字符可能会被编码
例：
String url = "http://www.baidu.com/signedUrl%3Fsignature=eyJhbGciOiJSUzI1NiJ9.ey"; String url2 = "http://192.168.73.88:9099/hefei/decision/road/cartrack?type=bus%26carId=1123%26startTime=2020-12-18%2012:10:01%26endTime=2020-12-18%2014:20:16";
这里面的 %3F 应该是 ? ，%26 是 & ，那么如何转回去
package com.x; import java.io.UnsupportedEncodingException; import java.net.URLDecoder; import java.net.URLEncoder; public class Test { public static void main(String[] args) throws UnsupportedEncodingException { String url = "http://127.0.0.1:9099/hefei/decision/road/cartrack?type=bus%26carId=1123%26startTime=2020-12-18%26endTime=2020-12-18"; String url2 = "http://192.168.73.88:9099/hefei/decision/road/cartrack?type=bus%26carId=1123%26startTime=2020-12-18%2012:10:01%26endTime=2020-12-18%2014:20:16"; String deurl = URLDecoder.decode(url, "UTF-8"); String deurl2 = URLDecoder.decode(url2, "UTF-8"); System.out.println("deurl:" + deurl); System.out.println("deurl2:" + deurl2); System.out.println(); // 再次decode不会影响结果 String decode = URLDecoder.decode(deurl, "UTF-8"); String decode2 = URLDecoder.decode(deurl2, "UTF-8"); System.out.println("decode:" + decode); System.out.println("decode2:" + decode2); System.out.println(); String encodeUrl = URLEncoder.encode(deurl, "UTF-8"); System.out.println("encodeUrl:" + encodeUrl); String decodeUrl = URLDecoder.decode(encodeUrl, "UTF-8"); System.out.println("decodeUrl:" + decodeUrl); } }
