问题 I'm trying to migrate an old project to Retrofit library and this project has quite tricky API.

How would my pojo class look like and what can i use to parse this dynamic json? 回答1: For your case you can use Call<JsonElement> as response type and parse it in response: call.enqueue(new Callback<JsonElement>() { @Override public void onResponse(Call<JsonElement> call,
