将JSON字符串导入java

Question

是否可以将JSON字符串数组转换为java数组

例如类似于这个http://api.soundrop.fm/spaces/XJTt3mXTOZpvgmOc的东西

我需要获取当前播放和艺术家的值

Answer 1

我建议使用json-lib将JSON序列化为Java对象

然后可以从该对象获取JSONArray，并在其自己的数组中对其进行排序

示例：

JSONObject json = new JSONObject(jsonString);
JSONArray owners = (JSONArray) json.get("owners");

Iterator<String> iterator = owners.iterator();
while (iterator.hasNext()) {
    System.out.println(iterator.next());
}

输出：

Wr3pWSGt54GlRiEL
XJU7ZqZ3MYrQncIw

格式化JSON:

Answer 2

这是JSON格式，或者至少看起来是这样，有JSON的java解析器，所以尝试使用它，它将生成映射，而不是数组
