[英]JSON - Create JSONObject with array
I need to create in a Java (Android) a JSONObject/JSONArray with the exact following structure: 我需要在Java(Android)中创建具有以下确切结构的JSONObject / JSONArray:
{
"listId":
[
"c02bc683-fcd7-47a5-b157-853e26ed099e",
"f8e1c9d7-ae45-4433-a315-726c1d912d09"
]
}
Can somebody help me on this please? 有人可以帮我吗?
EDIT: 编辑:
What i have is this: 我所拥有的是:
JSONArray obj = new JSONArray();
JSONObject jsonObject = new JSONObject();
jsonObject.put("listId", folderId);
obj.put(jsonObject);
JSONObject json = new JSONObject();
json.put("id", obj);
But this produces something like: 但这会产生类似以下内容:
{
"listId":
[
{"id":"c02bc683-fcd7-47a5-b157-853e26ed099e"},
{"id":"f8e1c9d7-ae45-4433-a315-726c1d912d09"}
]
}
Thanks 谢谢
You've got your array creation a bit mixed up. 您的数组创建有些混乱。 What you really want is an object holding an array of string, but what you're doing is creating an array of
JSONObject
. 您真正想要的是一个包含字符串数组的对象,但是您正在做的是创建
JSONObject
数组。
Try this instead: 尝试以下方法:
String[] arr = { "c02bc683-fcd7-47a5-b157-853e26ed099e", "f8e1c9d7-ae45-4433-a315-726c1d912d09" };
JSONArray jsonArray = new JSONArray(arr);
JSONObject json = new JSONObject();
json.put("listId", jsonArray);
System.out.println(json); // {"listId":["c02bc683-fcd7-47a5-b157-853e26ed099e","f8e1c9d7-ae45-4433-a315-726c1d912d09"]}
