将数组中任何 json 对象的键值的类型从字符串更改为浮点/双精度

Question

我有一个 JSON 如下：

* def first = [{"country":"X","code":"XY","cityName":"XYZN","city":"XYZ","timezone":"XYZT","latitude":"57.0928","name":"XYZN","longitude":"9.8492"}, {"country":"A","code":"AB","cityName":"ABCN","city":"ABC","timezone":"ABCT","latitude":"1.234","name":"ABCN","longitude":"29.8482"}]
def second = [{"country":"X","code":"XY","cityName":"XYZN","city":"XYZ","timezone":"XYZT","latitude":57.0928,"name":"XYZN","longitude":9.8492}, {"country":"A","code":"AB","cityName":"ABCN","city":"ABC","timezone":"ABCT","latitude":1.234,"name":"ABCN","longitude":29.8482}]

我想比较这两者，但它失败了，因为第一个 JSON 将经度和纬度作为字符串，而第二个 JSON 将它们作为数字。

另外，我不想更改第二个json，必须按原样使用。

请建议如何先将类型从字符串更改为数字？ 我试过 https://github.com/intuit/karate#floats-and-integers

但它不适用于对象数组。

Scenario:
* def first = [{"country":"X","code":"XY","cityName":"XYZN","city":"XYZ","timezone":"XYZT","latitude":"57.0928","name":"XYZN","longitude":"9.8492"}, {"country":"A","code":"AB","cityName":"ABCN","city":"ABC","timezone":"ABCT","latitude":"1.234","name":"ABCN","longitude":"29.8482"}]
* def second = [{"country":"X","code":"XY","cityName":"XYZN","city":"XYZ","timezone":"XYZT","latitude":57.0928,"name":"XYZN","longitude":9.8492}, {"country":"A","code":"AB","cityName":"ABCN","city":"ABC","timezone":"ABCT","latitude":1.234,"name":"ABCN","longitude":29.8482}]
* def first_formatted = []
* def fun = function(x){x.latitude = Number(x.latitude); x.longitude = Number(x.longitude); karate.appendTo(first_formatted, x); }
* karate.forEach(first, fun)
* print first_formatted
* match first_formatted == second
