由Google Maps Query返回的JSON包含编码字符，如\x26（如何解码？） [英] JSON returned by Google Maps Query contains encoded characters like \x26 (how to decode?)

问题描述

在一个Java应用程序中，我得到了JSON（来自Google Maps），其中包含字符如 \x26 ，我想将它转换为原始字符 &安培; 。据我所知，这是一个UTF-8符号，但我不完全确定。在源JSON中，可以出现各种编码字符（例如 \ x3c / div\x3e ）。如何解码它们？

我试过了：

 字符串json =\\x3c / div\\x3e; 
 byte [] b = json.getBytes（UTF-8）; 
 json = new String（b，UTF-8）; 
  

没有运气。任何想法？

解决方案

> 字符串json =\\x3c / div\\x3e;
json = URLDecoder.decode（\\，％） ）
.replace（\\&，=）
.replace（\\？，=）;


Google地图查询JSON结果导致的其他问题需要另外三个替换。

In a Java app, i get JSON (from Google Maps) with characters like \x26 which i want to convert to its original character &. As far as i can see, that's a UTF-8 notation, but i am not completely sure. In the source JSON all kinds of encoded characters can appear (e.g. \x3c/div\x3e). How can i decode them?

I tried:

String json = "\\x3c/div\\x3e";
byte [] b = json.getBytes("UTF-8");
json = new String(b,"UTF-8");

No luck. Any ideas?

解决方案

Got it to work:

String json = "\\x3c/div\\x3e";        
json = URLDecoder.decode(json.replace("\\x", "%"), "UTF-8")
        .replace("\\=", "=")
        .replace("\\&", "=")
        .replace("\\?", "=");

The three other replaces are needed for other problems that occur with the result of a Google Maps Query JSON Result.
