如何解析此 JSON object 以获取我可以使用的配方对象列表？

Question

So I am incredibly new to Java and am needing help parsing a JSON response. I already have the method in which I am using to do so, but need help figuring out what exactly I am doing wrong.

I am using an API to retrieve recipes from a site. I am trying to get a list of recipes ("hits" in this case I assume?) that I can then show to the user.

Obviously I need the recipe name ("label" in this case) and other information. Can anyone help me?

Here is the response api response I am getting:

{
   "q": "chicken",
   "from": 0,
   "to": 10,
   "more": true,
   "count": 168106,

This is currently the method I am using to parse the JSON object:

public void onResponse(Call call, Response response) throws IOException {

                    if (response.isSuccessful()) {
                        final String myResponse = response.body().string();
                        getActivity().runOnUiThread(new Runnable() {
                            private Object Date;

                            @Override
                            public void run() {
                                String jsonData = myResponse;
                                query_result.setText(myResponse);
                                Log.d("response5", myResponse);
                                //JSONObject jsonData1 = new JSONObject(myResponse);
                                JSONObject Jobject = null;
                                try {
                                    Jobject = new JSONObject(jsonData);
                                    Log.d("jobject", Jobject.toString());
                                } catch (JSONException e) {
                                    e.printStackTrace();
                                }
                                JSONArray Jarray = null;
                                try {
                                    Jarray = Jobject.getJSONArray("hits");
                                } catch (JSONException e) {
                                    e.printStackTrace();
                                }

                                for (int i = 0; i < Jarray.length(); i++) {
                                    JSONObject object;
                                    try {
                                        object = Jarray.getJSONObject(i);
                                        try {
                                            JSONArray Recipe = object.getJSONArray("recipe");
                                        }catch (JSONException e){
                                            e.printStackTrace();
                                        }
                                        for (int j = 0; j < Jarray.length(); j++){
                                            JSONObject object2 = null;
                                            try {
                                                object2 = Jarray.getJSONObject(j);
                                                String Name = object2.getString("label");
                                                String Photo = object2.getString("image");
                                                Log.d("rec_query", " " + Photo);
                                            }catch (JSONException e){
                                                e.printStackTrace();
                                                Log.d("response6:", e.toString());
                                            }
                                        }

                                    } catch (JSONException e) {
                                        e.printStackTrace();
                                    }
                                }

                            }
                        });
                    }
                }
            });

            return null;
        }
    }

NOTE THE {} {} are just different recipes...it wouldnt fit the whole response

At the moment, when I try to print my variables in the Log, I am getting a message that says the variable is empty (the variable that i used to store the different recipes/"hits".

Answer 1

Your response seems incomplete, it's not in the correct JSON format，Provide the right format and I'll try to help you

Answer 2

     String s = "{\n" +
            "    \"a1\":\"1\",\n" +
            "    \"b2\":[\n" +
            "        {\n" +
            "            \"b21\":\"vb21\"\n" +
            "        },\n" +
            "        {\n" +
            "            \"b22\":\"vb22\"\n" +
            "        }\n" +
            "    ]\n" +
            "}";
    JSONObject object = JSON.parseObject(s);
    String vb21 = object.getJSONArray("b2").getJSONObject(0).getString("b21");

like this,and neep to import com.alibaba.fastjson But i dont`t know if you can use fastjson
