How to create a class to get the json response of a service which returns in an structure like the f-CodePudding

The webservice return the following JSON string:

{"errorCode":0,"error":"","status":"OK","data":{"id":"1234A"}}

So to get a class that receives the response in a function like this that performs a post in Retrofit:

Call<UploadImageData> postData(@Header("Cookie") String sessionId, @Body UploadImageModal image);

I'd need to make a class like this;

public class UploadImageData {
    private int errorCode;
    private String error;
    private  String status;
}

But I'm lost in how I would have to declare the part that would take "data":{"id":"1234A"}, so it gets the data from there correctly.

How could I do this?

CodePudding user response：

Since data is a nested object within the surrounding json object, you can include it as another class in your UploadImageData class.

public class UploadImageData {
    private int errorCode;
    private String error;
    private String status;
    private MyDataClass data;
}

public class MyDataClass {
    private String id;
}

Don´t forget setter methods oder make fields public.

CodePudding user response：

import net.sf.json.JSONObject;

String json ="{\"errorCode\":0,\"error\":\"\",\"status\":\"OK\",\"data\":{\"id\":\"1234A\",\"id\":\"14A\"}} ";

private static void resolveJson(String json) {
    JSONObject jsonObj = JSONObject.fromObject(json);
    System.out.println(jsonObj.get("errorCode"));
    System.out.println(jsonObj.get("error"));
    System.out.println(jsonObj.get("status"));
    JSONObject data = jsonObj.getJSONObject("data");
    System.out.println(data.get("id"));
}

Output:

0

OK
["1234A","14A"]
