json - 使用 Jolt 规范根据子属性的值重命名属性

Question

我需要更改 JSON 属性的名称，但前提是子属性的值是特定值。在下面的示例中，我想重命名data.relationships.policyHolder为，data.relationships.companies但前提是data.relationships.policyHolder.data.typeequals "companies"。颠簸可以做这样的事情吗？

输入

{
"data": {
    "type": "clients",
    "id": "U5QYNSHY27CPD6DBQL2PRV6EU2BIJZ6G6STH47Q-",
    "relationships": {
        "policyHolder": {
            "data": {
                "type": "companies",
                "id": "U5QYNSHY27CPD6DBQL2PRV6EU34NPSGEQKCOPRXUUZ7H4---"
            }
        },
        "persons": {
            "data": {
                "type": "persons",
                "id": "6H4IN45HMHCKN6MG27ZE5V6EU34NPRVD6GB6PEI-"
            }
        }
    }
}

}

输出

{
"data": {
    "type": "clients",
    "id": "U5QYNSHY27CPD6DBQL2PRV6EU2BIJZ6G6STH47Q-",
    "relationships": {
        "companies": {
            "data": {
                "type": "companies",
                "id": "U5QYNSHY27CPD6DBQL2PRV6EU34NPSGEQKCOPRXUUZ7H4---"
            }
        },
        "persons": {
            "data": {
                "type": "persons",
                "id": "6H4IN45HMHCKN6MG27ZE5V6EU34NPRVD6GB6PEI-"
            }
        }
    }
}
