Json String无法使用json-simple toolkit java进行解码

Question

JSON-Simple

JSON-Simple Example

String login = "{\"result\":[104192,42068],\"id\":1}";

Object obj = JSONValue.parse(login);

JSONArray array = (JSONArray)obj;

This throw a exception

Exception in thread "main" java.lang.ClassCastException: org.json.simple.JSONObject cannot be cast to org.json.simple.JSONArray

What is the problem in this code ?

Answer 1

在这种情况下，解析后的结果是JSONObject因此您需要将其JSONObject为JSONObject 。

Answer 2

I had this problem and I have fixed it. Here is my code snippet:

Object obj = JSONValue.parse(response.getBody());
JSONObject jsonObject = (JSONObject) obj;
Object gu_obj = jsonObject.get("guid");

I got the yahoo user guid from the request body. Hope this helps :)

Answer 3

You are trying to cast an object into an array. Try adding the object to the array instead.
