如何使用动态字段名称断言空手道响应

Question

API 响应示例：

{
    "topic1": [
        {"fieldName2": "value2",fieldName1": "value1"}
    ],
    "topic2": [
        {"fieldName2": "value2","fieldName1": "value1"},
        {"fieldName2":"anotherValue2","fieldName1": "anotherValue1"}
    ]
}

这会起作用：

Then match response.topic1 == [{"fieldName2": "value2",fieldName1": "value1"}]
And match response == {"topic1":[{"fieldName2": "value2",fieldName1": "value1"}]}

但我需要将“topic1”放在这样的变量中，但无法找到使其工作的方法。

Then match response.TOPIC_NAME== [{"fieldName2": "value2",fieldName1": "value1"}]

也只尝试了 response.<TOPIC_NAME> 和 match response contains 消息，但也没有用。

    * print "KAFKA_TOPIC: ", KAFKA_TOPIC
    * print "response.KAFKA_TOPIC:", response.KAFKA_TOPIC
    * print "response.topic1: ", response.topic1

日志：

11:47:47.946 [main]  INFO  com.intuit.karate - [print] KAFKA_TOPIC: topic1
11:47:47.949 [main]  INFO  com.intuit.karate - [print] response.KAFKA_TOPIC: null
11:47:47.951 [main]  INFO  com.intuit.karate - [print] response.topic1:  [
  {
    "fieldName1": "value1",
    "fieldName2": "value2",
    "fieldName2": "value3"
  }
]

现在尝试探索 https://github.com/karatelabs/karate#json-transforms 如果没有直接的方法。

您可以使用如下动态键访问 JSON：object[keyName]。这只是幕后的 JS。这个例子应该让你的选择更清楚：

* def response =
"""
{
  "topic1": [
    {
      "field1": "value1"
    }
  ]
}
"""
* def key1 = 'topic1'
* def val1 = response[key1]
* match val1 == [{ field1: 'value1' }]
# to do this in one line
* match (response[key1]) == [{ field1: 'value1' }]
