Jmeter - JSON提取器

Question

我正在尝试创建一个json表达式路径，它在引用{" id ":" 00000000000000000000000004640254 "}时返回id。我已经尝试过

$.[?(@.Relationship[?(@.Ref.id=='00000000000000000000000004640254')])].id

但是它不返回数据

Json消息是

[
    {
        "id": "234567890234567890",
        "Relationship": [
            {
                "type": "Indirect",
                "Ref": {"id": "00000000000000000000000004640253_01"}
            },
            {
                "type": "Direct",
                "Ref": {"id": "00000000000000000000000004640254"}
            }
        ],
        "Specification": {"id": "Gold123AS"}
    },
    {
        "id": "234567890234567891",
        "Relationship": [
            {
                "type": "Indirect",
                "Ref": {"id": "00000000000000000000000004640253_02"}
            },
            {
                "type": "Direct",
                "Ref": {"id": "00000000000000000000000004640253"}
            }
        ],
        "Specification": {"id": "Gold123AS"}
    }
]

如果有人能帮我，谢谢

我不认为使用JSON Extractor可以做到这一点，因为返回父节点是not implemented by underlying JsonPath library

换成JSR223 PostProcessor和Groovy语言，相关代码应该是这样的：

def json = new groovy.json.JsonSlurper().parse(prev.getResponseData())

0.upto(json.size() -1 , { idx ->
    if (json.get(idx).Relationship.find { it.Ref.id.equals('00000000000000000000000004640254') } != null) {
        vars.put('id', json.get(idx).id as String)
        return
    }
})
