无法从Java中的JsonNode获取值

Question

I have a json string as below :

"{\"event\":\"PremiumAdsViews\",\"data\":{\"id\":12,\"category_id\":12,\"category_gid\":11,\"adStyle\":\"T\"}}"

When I am trying to convert it into JsonNode, I get the JsonNode as below and I am not able to access any value from get method of JsonNode

{"_value":"{\"event\":\"PremiumAdsViews\",\"data\":{\"id\":12,\"category_id\":12,\"category_gid\":11,\"adStyle\":\"T\"}}"}

How can we parse the json string with double quotes on rear end into pure jsonNode ?

Answer 1

 JSONParser jsonParser = new JSONParser();
 JSONObject jsonObject = (JSONObject) jsonParser.parse(tmpStr);
 System.out.println("NodeValue:" + (String) jsonObject.get("event"));

you can try this
