Question

我想验证一个JSON模式，其中嵌套JSON响应中的对象是可选的，但是如果该对象出现，则该对象中的键也应该出现。

样品响应：-

{
    "id" : "1234",
    "targetPhoneNumber" : "1234",
    "paid" : { //optional
      "units" : "asd", //mandatory if the paid object is coming
      "amount" : 12.00 //mandatory if the paid object is coming
    },
    "date" : "2019",
    "boolean" : false,
    "transactionId" : "1234"
  }

对于这些情况，我需要进行模式检查。

1）如果付费对象即将到来，则它应该是JSON对象，并且应包含字符串形式的单位和金额（必填）。 2）如果仍然没有付费对象，则模式验证应通过。

结合使用'self' validation expressions和karate.match(actual, expected) API提供了一些方法来实现这一目标，

这应该有效，

* def schema =
"""
{
      "boolean": "#boolean",
      "date": "#string",
      "id": "#string",
      "paid": "##object? karate.match(_,{\"amount\": \"#number\",\"units\": \"#string\"}).pass",
      "targetPhoneNumber": "#string",
      "transactionId": "#string"
}
"""

如果您不想内联添加subSchema /如果子模式太大，则可以尝试

* def passSchema =
"""
{
    "amount": "#number",
    "units": "#string"
}
"""
* def schema =
"""
{
    "boolean": "#boolean",
    "date": "#string",
    "id": "#string",
    "paid": "##object? karate.match(_,passSchema).pass",
    "targetPhoneNumber": "#string",
    "transactionId": "#string"
}
"""

简单的JSON模式：

{
      "boolean": "#boolean",
      "date": "#string",
      "id": "#string",
      "paid": "##object? karate.match(_,{\"amount\": \"#number\",\"units\": \"#string\"}).pass",
      "targetPhoneNumber": "#string",
      "transactionId": "#string"
}

有条件的话可以这样做：

* def outerMatcher =
"""
{
"id" : "#string",
"targetPhoneNumber" : "#string",
"paid" : "##object",
"date" : "#string",
"boolean" : "#boolean",
"transactionId" : "#string"
}
"""

* def paidMatcher =
"""
{
  "units": "#string",
  "amount": "#number"
}
"""

* def innerMatcher = karate.match(response.paid, "#object").pass ? paidMatcher : "#notpresent"

* match response == outerMatcher
* match response.paid == innerMatcher

空手道DSL：如何检查JSON对象是否可选，但是该对象是否来自该对象内的密钥应具有正确的架构？
