我对JSONPath相当陌生,所以这可能是我的错,但是当我在在线评估器(https://jsonpath.com/)中尝试这个表达式时,它有效,但在空手道中无效。
$..entry[?(@.resource.resourceType == 'AllergyIntolerance' && @.resource.category=='food')].resource.code.coding.*.system
如果我使用索引,我可以取出第一个元素,但我想抓取与表达式匹配的所有元素,而不管它们的索引如何,以防数组中有更多项目而不是我的特定数据示例。
工作JSON路径:
$..entry[?(@.resource.resourceType == 'AllergyIntolerance' && @.resource.category[0]=='food')].resource.code.coding.*.system
我尝试使用通配符,但这似乎不起作用:
$..entry[?(@.resource.resourceType == 'AllergyIntolerance' && @.resource.category[*]=='food')].resource.code.coding.*.system

众所周知,JsonPath引擎在处理如此复杂的表达式时存在问题。请使用< code >空手道.过滤器()来代替,我相信你会同意这是更可读的:https://github.com/intuit/karate#json-transforms
* def resources = $..resource
* def fun = function(x){ return x.resourceType == 'AllergyIntolerance' && x.category[0] == 'food' }
* def temp = karate.filter(resources, fun)
