如何在两个json数组上循环并用karate过滤结果

Question

我有2个JSON数组

a= [{"[{ "Id": "123","Types": "Dial"},{"Id": "963", "Types": "Post"},{"Id": "456","Types": "Dial"},
{ "Id": "569","Types": "Dial"}]

b= [{"Subject": {"Prog": [{"Type": "Identifier","Id": "123"}]}},
{"Subject": {"Prog": [{"Type": "Identifier" ,"Id": "569"}]}},
{"Subject": {"Prog": [{"Type": null,"Id": "963"}]}},
{"Subject": {"Prog": [{"Type": null,"Id": "963"}]}},
{"Subject": {"Prog": [{"Type": null,"Id": "963"}]}},
{"Subject": {"Prog": [{"Type": null,"Id": "963"}]}},
{"Subject": {"Prog": [{"Type": "Identifier","Id": "456"}]}}]

我想从"a"验证"；类型"；值为"0"；POST"；，对于相应的"；id"；在JSON中"；b"类型"；具有值"；空"；

请帮忙。

您可以通过使用Json路径集成和空手道来实现这一点，也可以使用过滤器功能。

* def IdArray = karate.jsonPath(a,"$..[?(@.Types=="Post")].Id")  
* def FilteredArray = call FilterFunction(IdArray,b)

您可以将过滤功能定义为

* def FilterFunction =
"""
function(arr,b)
{ var result = []
for(i=0;i<arr.length;i++)
{ var Mypath = "$..[?(@.Id==""+ arr[i] +"")].Type"
var newArr = karate.jsonPath(b,Mypath)
karate.apend(result,newArr)
}
return result
}
""""

这样filteredArray将包含所有空值。只需对该数组应用空值检查即可。
