我想使用JOLT转换库重命名嵌套在另一个数组中的数组中的字段。 1.要重命名的一个字段是数组中的顶级字段 2.要重命名的两个字段位于嵌套数组
中我尝试过使用通配符,但是他们没有给我预期的输出。我使用的是JOLT 0.0.22版本。
输入JSON:
{
"country": "usa",
"state": [
{
"stateName": "TX",
"location": "south",
"cities": [
{
"name": "Austin",
"pop": "1M"
},
{
"name": "Dallas",
"pop": "2M"
}
]
},
{
"stateName": "CA",
"location": "west",
"cities": [
{
"name": "SanFran",
"pop": "3M"
},
{
"name": "LosAngeles",
"pop": "4M"
}
]
}
]
}
预期产出:
{
"country": "usa",
"state": [
{
"stateName": "TX",
"locatedIn": "south", // name change here
"cities": [
{
"cityname": "Austin", // name change here
"citypopulation": "1M" // name change here
},
{
"cityname": "Dallas",
"citypopulation": "2M"
}
]
},
{
"stateName": "CA",
"locatedIn": "west",
"cities": [
{
"cityname": "SanFran",
"pop": "3M"
},
{
"cityname": "LosAngeles",
"citypopulation": "4M"
}
]
}
]
}

为了比较,这是JSLT中的解决方案。
{
"state" : [for (.state) . | {
"locatedIn" : .location,
"cities" : [for (.cities) {
"cityname" : .name,
"citypopulation" : .pop
}],
* : .
}],
* : .
}
