Question

假设我有这个流行的数据样本。

{
    "store": {
        "book": [
            {
                "category": "reference",
                "author": "Nigel Rees",
                "title": "Sayings of the Century",
                "price": 8.95
            },
            {
                "category": "fiction",
                "author": "Evelyn Waugh",
                "color": "red", 
                "title": "Sword of Honour",
                "price": 12.99
            },
            {
                "category": "fiction",
                "author": "Herman Melville",
                "color": "blue", 
                "title": "Moby Dick",
                "isbn": "0-553-21311-3",
                "price": 8.99
            },
            {
                "category": "fiction",
                "author": "J. R. R. Tolkien",
                "title": "The Lord of the Rings",
                "isbn": "0-395-19395-8",
                "price": 22.99
            }
        ],
        "bicycle": {
            "color": "red",
            "price": 19.95
        }
    },
    "expensive": 10
}

我想要的是book所有category == fiction以及所有bicycle color == red。

就是说，我想要，

   {
        "category": "fiction",
        "author": "Evelyn Waugh",
        "color": "red", 
        "title": "Sword of Honour",
        "price": 12.99
    },
    {
        "category": "fiction",
        "author": "Herman Melville",
        "color": "blue", 
        "title": "Moby Dick",
        "isbn": "0-553-21311-3",
        "price": 8.99
    },
    {
        "category": "fiction",
        "author": "J. R. R. Tolkien",
        "title": "The Lord of the Rings",
        "isbn": "0-395-19395-8",
        "price": 22.99
    },
    "bicycle": {
         "color": "red",
         "price": 19.95
    }

我知道，我可以使用$.store.book[?(@.category == "fiction")]来实现目标书籍，$.store.bicycle[?(@.color == 'red')]来实现目标自行车。

但我怎样才能一次性实现这两个目标？

Answer 1

您可以使用&&和||运营商。

$.store.*[?(@.color== 'red' || @.category == 'fiction')]

将根据需要获取结果

Answer 2

我建议您使用JSR223 PostProcessor和Groovy language来实施您的方案。从过滤后的数据中提取元素和构建新JSON的示例代码如下所示：

import groovy.json.JsonBuilder
import groovy.json.JsonSlurper

def json = new JsonSlurper().parseText(prev.getResponseDataAsString())

def fictionBooks = json.store.book.findAll {it.category == "fiction"}
def redBikes = json.store.bicycle.findAll{it.color="red"}

JsonBuilder builder = new JsonBuilder(fictionBooks + redBikes)

prev.setResponseData(builder.toPrettyString())

以上代码将使用筛选的JSON

替换父采样器响应数据

要退还书籍和自行车，您需要：

ValidateLogin(e)
{
    if(this.state.formValid)
    {
        let userid = this.state.userId;
        let password = this.state.password;
         let url = "http://localhost:3727/api/Login/ValidateUser";
            fetch(url, {
            method: "POST",
            mode: 'no-cors',
            body : "userid=" + userid +"&password=" +  password
            }).then((response) => console.Log(respose));
    }
};

对于颜色为==红色或类别==小说的书籍，您需要：

$..*[?(@.color== 'red' || @.category == 'fiction')]

如何在jmeter的json路径提取器中连接两个json路径查询？
