Java JsonObject数组的键值 [英] Java JsonObject array value to key

问题描述

我是Java的新手，所以这有点令人困惑

我想获取json格式的字符串

我想要的结果是

{ "user": [ "name", "lamis" ] }

我当前正在做的是这样:

JSONObject json = new JSONObject();         
json.put("name", "Lamis");
System.out.println(json.toString());

我得到这个结果

{"name":"Lamis"}

我尝试了这个，但是没有用 json.put("user"，json.put("name"，"Lamis")))

解决方案

尝试一下:

JSONObject json = new JSONObject();         
json.put("user", new JSONArray(new Object[] { "name", "Lamis"} ));
System.out.println(json.toString());

但是，您显示的错误"结果比正确"结果更自然地映射了存在具有 name 名称"的用户"lamis". /p>

为什么您认为正确"结果更好?

I'm new to java so this is a bit confusing

I want to get json formatted string

The result I want is

{ "user": [ "name", "lamis" ] }

What I'm currently doing is this :

JSONObject json = new JSONObject();         
json.put("name", "Lamis");
System.out.println(json.toString());

And I'm getting this result

{"name":"Lamis"}

I tried this but it didnt work json.put("user", json.put("name", "Lamis"));

解决方案

Try this:

JSONObject json = new JSONObject();         
json.put("user", new JSONArray(new Object[] { "name", "Lamis"} ));
System.out.println(json.toString());

However the "wrong" result you showed would be a more natural mapping of "there's a user with the name "lamis" than the "correct" result.

Why do you think the "correct" result is better?
