改造地图作为主体 - 如何使用内部 json 对象发布地图

Question

Retrofit2 我将如何使用具有内部 json 的地图 json 主体发布。让我给你举个例子：

{
    "id_invoice": 1234,
    "action": "viewed",
    "data": {
        "id_object": 88,
        "id_store": 43,
        "type": "payment"
     }
}

注意“数据”JSON 对象如何具有内部 JSON。如何将所有这些放入地图中，以便使用以下服务端点将其发送到改造：

public interface Api {
    @NonNull
    @POST("cart/payment")
    @Headers({"Content-Type:application/json"})
    Observable<ResponseBody> postPaymentEvent(@Body Map<String, Object> body);
}

我尝试了以下方法：

Map<String, Object> map = new HashMap<>();
JSONObject json = new JSONObject();
json.put("id_object", 88);
json.put("id_store", 43);
json.put("type", "payment");
map.put("action", "view");
map.put("id_invoice", 1234);
map.put("data", json); //this is wrong. it creates the following response with a nameValuePairs field, which is not what i want:

正文：

{
    "action": "page_view",
    "id_invoice": "1234",
    "data": {
        "nameValuePairs": {
            "id_object": 88,
            "id_store": 43,
            "type": "view"
         }
    }
}

Answer 1

这样做：

 JSONObject dataJson = new JSONObject();
            try {
                JSONObject parentJson = new JSONObject();

                dataJson.accumulate("id_object", 88);
                dataJson.accumulate("id_store", 43);
                dataJson.accumulate("type", "payment");


                parentJson.accumulate("id_invoice",1234);
                parentJson.accumulate("action","viewed");
                parentJson.put("data",dataJson);



                Log.d("Main Screen ",parentJson.toString());
            } catch (JSONException e) {
                e.printStackTrace();
            }

它会生成这个：

{
  "id_invoice": 1234,
  "action": "viewed",
  "data": {
    "id_object": 88,
    "id_store": 43,
    "type": "payment"
  }
}
