  "success_message": "Coupon applied successfully",
  "error_message": "Coupon not applicable"
}

现在这是我的功能文件代码，它加载 json 文件并尝试只修剪我想要的 json

Scenario: Json formatting
* def discountInput = read('Dis.json')
* remove discountInput.rules.AND[0]
* remove discountInput.rules.AND[2]
* remove discountInput.rules.AND[3]
* remove discountInput.rules.AND[4]
* remove discountInput.rules.AND[5]
* remove discountInput.rules.AND[6]
* remove discountInput.rules.AND[7]
* remove discountInput.rules.AND[8]
* remove discountInput.rules.AND[9]
* remove discountInput.rules.AND[10]
* remove discountInput.rules.AND[11]
* remove discountInput.rules.AND[12]
* print discountInput

当我打印这个时，只有 AND[0] 被删除，但我想删除除 AND[1] 之外的所有内容，我该如何在空手道中做到这一点？

还有比我目前做的更好的方法吗？

【问题讨论】：

我试过 * remove discountInput.rules.AND[0],discountInput.rules.AND[1],discountInput.rules.AND[2] ......但没用
我试过 * remove discountInput.rules.AND[0,2,3,4,5,6,7,8,9..] 没用

【解决方案1】：

快速回答：

Scenario: Json formatting 
    * def discountInput = read('Dis.json') 
    * def andNode = discountInput.rules.AND[1]
    * remove discountInput.rules
    * set discountInput.rules[0] = andNode

这可能不是一个好的解决方案，我只是想减少你的代码行

编辑：

再来一个答案，

您可以根据提供给 karate.filter 的条件过滤 json，而不是尝试删除数据

Scenario: json filter 
    * def discountInput = read('Dis.json') 
    * def filterCondition = function(x) { if(x.RULE){ return true;}} 
    * def allAND = $discountInput.rules.AND[*]
    * set discountInput.rules = karate.filter(allAND, filterCondition)

所有符合条件的数据都会从过滤器函数中返回为json数组

从上面的例子中，无论哪个 AND 节点都有一个规则，都会被返回

您还可以将上述任何答案与Scenario Outline: 一起使用，并从您的Examples: 传递索引/过滤条件

【讨论】：

谢谢！我个人认为使用 JS 手动创建 JSON 可能要容易得多！我现在很忙，但试试* if (condition) rules.AND[i] = { blah: '1' }
peter，删除不支持表的设置是否正确？
是的，没有要删除的表。这可能是karate.filter() 可以提供帮助的地方
Payload 将保持不变，只有规则会改变（在每个场景中，一些规则将从有效负载中删除）所以我想用这种方式实现，而不是通过 JS 构建整个 JSON。
那么上面的答案应该可以正常工作，而不是有多个场景，您可以在示例中使用带有规则索引的场景大纲。

【解决方案2】：

试试这个：

#{
#"RULE": {
#  "operator": "EQUALS_LT",
#  "attribute_name": "CHECKOUT",
#  "attribute_value": "16 Nov 2018",
#  "attribute_value_type": "DATE",
#  "status": "ACTIVE"
#}
#}
Scenario:
* def data = { op: 'EQUALS_LT' }
* set rule1
| path | 0 | 1 |
| RULE.operator | data.op | 'AND' |
| RULE.attribute_name | (null) | 'bbb' |
| RULE.attribute_valule | '16 Nov 2018' | 'ggg' |
| RULE.attribute_value_type | 'DATE' | 'ddd' |
| RULE.status | 'ACTIVE' | 'jjj' |

* print rule1
* set rule2
| path | 0 | 1 |
| RULE.operator | data.op | rule1 |
| RULE.attribute_name | (null) | 'bbb' |
| RULE.attribute_valule | '16 Nov 2018' | 'ggg' |
| RULE.attribute_value_type | 'DATE' | 'ddd' |
| RULE.status | 'ACTIVE' | 'jjj' |

* print rule2
