将数组中任何json对象的键值的类型从字符串更改为浮点型/双精度型 [英] Change type from string to float/double for a key value of any json object in an array

问题描述

我有一个json，如下所示：

* 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}]

我想比较这两个，但失败了，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。

请建议如何在First中将类型从字符串更改为数字？ 我尝试了https://github.com/intuit/karate#floats-and-integers

但它不适用于对象数组。

推荐答案

示例代码：

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
