请参考以下解析 json 响应的方法，如果您在字符串中获得响应，否则删除 JSONArray array = new JSONArray("res") 行，如果获取 json 数组。

try {
                    JSONArray array = new JSONArray("res");

                    for (int i = 0; i < array.length(); i++) {
                        JSONObject jsonObject = array.getJSONObject(i);

                        String vendor_name = jsonObject.getString("vendor_name");// same way parse all string


                        if(jsonObject.has("dish_description")){

                        String dish = jsonObject.getString("dish_description");

                        dish = dish.replaceAll("[\\W]", "");

                        JSONObject  jsonObject2 = new JSONObject(dish);

                        String  main = jsonObject2.getString("main");// same way get other one 


                        }


                    }
                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
