问题描述

我有JSON字符串，我想使用正则表达式从中提取一个字段.该字段可以是Object，Array，String，int或任何类型.我知道另一种方式，例如遍历JSON中的所有键并找到它.我想知道，是否可以使用Regex来实现.任何帮助都会很棒.

I have JSON String I would like to extract a Field from it Using Regex. The field can be an Object, Array, String, int or any type. I Know the other way like looping through all the keys in the JSON and finding it. I would like to know, This can be achieved using Regex or not. Any help would be great.

推荐答案

这可以使用或不使用正则表达式来实现

This can be achieved using Regex or not

不合理，不，因为正则表达式不太适合自行解释JSON之类的结构；与HTML一样，您需要一个适当的解析器.

Not reasonably, no, because regular expressions are not well-suited to interpreting structures like JSON on their own; as with HTML, you want a proper parser.

相反，请使用多个Java库中的任何一个来解析JSON，然后遍历其内容.在 JSON站点的底部有一个列表(我看到的是

Instead, use any of the several Java libraries for parsing the JSON and then traversing its content; there's a list of them at the bottom of the JSON site (I see Gson used a lot, but there are lots of options).
