Question

我试图返回"dependentPreferences“中的"description”值，其中响应满足两个条件:首先，检查名称是否为"John“，然后检查首选项中的”图像“是否等于"papaya.jpg”。

响应机构如下：

[    
    {
        "id": 1,
        "name": "John Smith",
        "description": null,
        "shortDescription": "No recorded interests.",
        "alias": "JS",
        "preferences": [
            {
                "id": 1,
                "description": "likes candy and papaya",
                "image": "papaya.jpg",
                "name": "Papaya",
                "dependentPreferences": [
                    {
                        "id": 1,
                        "description": "Fruit must be ripe",
                        "image": "ripe-papaya.jpg",
                        "name": "pap"
                    }
                ]
            }
         ]
    },
    {
        "id": 2,
        "name": "Jane Smith",
        "description": null,
        "shortDescription": "No recorded interests.",
        "alias": "JS",
        "preferences": [
            {
                "id": 1,
                "description": "likes candy and papaya",
                "image": "papaya.jpg",
                "name": "Papaya",
                "dependentPreferences": [
                    {
                        "id": 1,
                        "description": "Candy must be Skittles",
                        "image": "Skittles.jpg",
                        "name": "skt"
                    }
                ]
            }
         ]
    }
]

到目前为止，我已经尝试过这样的方法：

response.jsonPath().getString("find { it.name == 'John Smith' }.preferences.find {it.image == 'papaya.jpg'}.dependentPreferences.description 

但这是在抱怨语法。我知道这部分代码可以找到图像：

response.jsonPath().getString("find { it.name == 'John Smith' }.preferences.image

但我在构造第二个条件时遇到了困难。任何帮助都将不胜感激。

工作示例这里。这对我来说很管用：

def endpoint = "http://localhost:3130/ids.json"
def jsonResponse = get(endpoint).then().contentType(ContentType.JSON).extract().response()
def path = jsonResponse.jsonPath()

def result = path.getString("find { it.name == 'John Smith' }.preferences.find {it.image == 'papaya.jpg'}.dependentPreferences.description")

不过老实说:在JSON中，dependentPreferences是--对象的数组，所以如果数据与显示的数据不同，就有可能出错。
