jsonpath响应的断言问题 [英] Assertion Issue of jsonpath response

问题描述

我正在用Karate的bdd方法编写api测试自动化代码.
断言部分使我很难受.我的回答如下所示，当我调用该路径$.data.subscribers[0].products时，这给了我空空数组，这是由 http检查的://jsonpath.herokuapp.com/网站.但是，当我运行小黄瓜空手道功能时，它给我的响应为null，它仍然给我错误声明.它说的是实际的:

I'm writing api test automated codes with bdd method by Karate.
Assertion part pushes me hard. My response is like below, and when I called that path $.data.subscribers[0].products this gives me empty-null array as I checked by http://jsonpath.herokuapp.com/ website. However, when I run my gherkin Karate feature then It gave me the response as null, It still gives me error assertion. It says actual:

空，预期:空...

null, expected: null...

我看不到任何错误，该如何解决?是bug还是有任何方法可以解决?

I couldn't see any error, how can I fix this? Is it a bug or Is there any method to handle it?

我的答复:

{
  "meta": {
    "return_code": 0,
    "message": "success"
  },
  "data": {
    "sbs": [
      {
        "sbs_id": 32432432,
        "dt": "OTT",
        "pt": []
      },
      {
        "sbs_id": 455654445,
        "dt": "IPTV",
        "pt": []
      }
    ]
  }
}

我写的JsonPath:

JsonPath that I wrote:

$.data.sbs[0].pt[0]

空手道给予的断言:

com.intuit.karate.exception.KarateException: base-tvpp-cases.feature:316 
- path: $[0], actual: null, expected: null, reason: actual json-path does 
not exist

我在功能文件中编写的小黄瓜空手道代码: 我在下面都尝试过

Gherkin-Karate- code that I wrote in feature file: I tried both below

And match response.data.subscribers[0].products[0] == null
And match response.data.subscribers[0].products[0] == '#null'

推荐答案

只需使用JsonPath通配符(..或*).请注意，当您使用通配符时-结果总是 为JSON数组.这是您的解决方案:

Just use a JsonPath wildcard (.. or *). Note that when you use a wildcard - the result will always be a JSON array. Here is your solution:

* match response.data..subscribers[0].products[0] == []
