Karate 空手道-获取一个值，该值以char开头，从json响应的最后一个出现

我试图获取此json中存在的值'F20210518060000'

[{
    "name": "F20210518000000",
    "timestamp": "2021-05-18T00:00:00Z",
    "forecast_from": "2021-05-18T00:00:00Z",
    "forecast_to": "2021-05-27T00:00:00Z"
},
{
    "name": "T20210518000000",
    "timestamp": "2021-05-18T00:00:00Z",
    "forecast_from": "2021-05-18T00:00:00Z",
    "forecast_to": "2021-05-18T06:00:00Z"
},
{
    "name": "T20210518060000",
    "timestamp": "2021-05-18T06:00:00Z",
    "forecast_from": "2021-05-18T06:00:00Z",
    "forecast_to": "2021-05-18T12:00:00Z"
},
{
    "name": "F20210518060000",
    "timestamp": "2021-05-18T06:00:00Z",
    "forecast_from": "2021-05-18T06:00:00Z",
    "forecast_to": "2021-05-27T06:00:00Z"
},
{
    "name": "T20210518120000",
    "timestamp": "2021-05-18T12:00:00Z",
    "forecast_from": "2021-05-18T12:00:00Z",
    "forecast_to": "2021-05-18T18:00:00Z"
},
{
    "name": "T20210518180000",
    "timestamp": "2021-05-18T18:00:00Z",
    "forecast_from": "2021-05-18T18:00:00Z",
    "forecast_to": "2021-05-19T00:00:00Z"
}]

条件： 获取JSON中以“F”开头的最后一项

到目前为止我的代码： 尝试了不同的方法，但仍然没有得到想要的响应

输出：

有关于如何进一步的提示吗？

给你：

* def temp = null;
* def fun = function(x){ if (x.name.startsWith('F')) karate.set('temp', x.name) }
* karate.forEach(response, fun)
* match temp == 'F20210518060000'

有时最好避免使用JsonPath，请阅读以下内容：

我只是好奇，如果我想要得到第二个姓氏，当我有100+个这样的值时，应该使用什么样的正确方法？@Dhamo easy，使用

karate.filter（）

就可以得到长度。如果不清楚，一定要问另一个问题

* def temp = null;
* def fun = function(x){ if (x.name.startsWith('F')) karate.set('temp', x.name) }
* karate.forEach(response, fun)
* match temp == 'F20210518060000'
