Question

我正在使用提供给我的API，以学习用于声明JSON响应的常规脚本。

API是

https://api.nasa.gov/neo/rest/v1/feed?start_date=2019-06-10&end_date=2019-06-16&api_key= *************

您可以从此处获取密钥：https://api.nasa.gov/index.html#apply-for-an-api-key

这是json响应的一小部分：

当天文学的每个对象（在这种情况下为每个流星）与上述API的天文miss_distance大于0.05时，如何断言is_potentially_hazardous_asteroid是假的

我知道如何使用JsonSlurper解析响应，但是我不知道如何在每个对象中进行比较。抱歉，我是groovy和json的新手。

我尝试了以下方法，但还是没有运气

    import groovy.json.JsonSlurper
    def ResponseMessage = messageExchange.response.responseContent
    def obj = new JsonSlurper().parseText(ResponseMessage)
    obj.near_earth_objects.each{
        date,objects->objects.each{
            Object neo = it
            neo.close_approach_data.each{
                if((it.miss_distance.astronomical as Double)>0.05){
                    assert (neo.is_potentially_hazardous_asteroid == false)
                }
            }
        }
    }

我得到的错误：

   assert (neo.is_potentially_hazardous_asteroid == false) | | | | true

我应该提到我是在soapui上通过添加脚本断言来实现的

Answer 1

据我所知，您的代码可以正常工作...

我对您的脚本进行了一些调整，并得到了相同的结果（有效证明）...

obj.near_earth_objects.each { date, objects ->
  objects.each { neo ->
    if (neo.close_approach_data.find { it.miss_distance.astronomical.toDouble() > 0.05 }) {
      assert !neo.is_potentially_hazardous_asteroid
    }
  }
}
