JSON校验提示重复对象键错误，请求修正示例JSON

你的JSON出现重复键错误，是因为JSON对象不允许存在重复的键名，解析器会直接忽略重复的键，导致数据丢失或报错。核心问题及修正方案如下：

• 原recipes数组内的单个对象重复了mr_id和ingredients，需将两个食谱拆分为recipes数组的两个独立元素；
• 每个ingredients数组内的单个对象重复了食材相关字段，需将每个食材作为ingredients数组的独立对象。

修正后的JSON代码：

{
    "recipes": [
        {
            "mr_id": 1,
            "ingredients": [
                {
                    "ingredient_id": 2,
                    "quantity": 4,
                    "unit": "g",
                    "nutrients": [
                        {
                            "nutrient_id": 1,
                            "quantity": 2,
                            "unit": "g"
                        }
                    ]
                },
                {
                    "ingredient_id": 3,

                        }
