求助：Azure Logic Apps中跨域依赖属性的JSON Schema验证方案

以下是满足验证规则的JSON Schema，适配Azure Logic Apps的验证场景：

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "customFields": {
      "type": "object",
      "properties": {
        "paymentMethods": {
          "type": "array",
          "items": {
            "type": "object",
            "properties": {
              "tokenizedCard": { "type": "string" },
              "cardNumber": { "type": "string" }
            },
            "required": ["tokenizedCard"]
          }
        }
      },
      "required": ["paymentMethods"]
    },
    "paymentDetails": {
      "type": "object",
      "properties": {
        "method": {
          "type": "array",
          "items": {
            "type": "object",
            "properties": {
              "paymentType": { "type": "string", "enum": ["CREDIT_CARD", "UPI"] },
              "tokenizedCard": { "type": "string" }
            },
            "required": ["paymentType", "tokenizedCard"]
          }
        }
      },
      "required": ["method"]
    }
  },
  "required": ["customFields", "paymentDetails"],
  "allOf": [
    {
      "if": {
        "properties": {
          "paymentDetails": {
            "properties": {
              "method": {
                "contains": {
                  "properties": {
                    "paymentType": { "const": "CREDIT_CARD" }
                  }
                }
              }
            }
          }
        }
      },
      "then": {
        "properties": {
          "customFields": {
            "properties": {
              "paymentMethods": {
                "allOf": [
                  {
                    "items": {
                      "if": {
                        "properties": {
                          "tokenizedCard": {
                            "enum": {
                              "$data": "/paymentDetails/method[?(@.paymentType == 'CREDIT_CARD')].tokenizedCard"
                            }
                          }
                        }
                      },
                      "then": {
                        "required": ["cardNumber"]
                      }
                    }
                  },
                  {
                    "contains": {
                      "properties": {
                        "tokenizedCard": {
                          "enum": {
                            "$data": "/paymentDetails/method[?(@.paymentType == 'CREDIT_CARD')].tokenizedCard"
                          }
                        }
                      }
                    }
                  }
                ]
              }
            }
          }
        }
      }
    }
  ]
}

关键规则说明 #

• 基础结构验证：定义JSON的核心结构，确保customFields.paymentMethods和paymentDetails.method为必填数组，且数组项的基础字段（如tokenizedCard）必填。
• 条件触发逻辑：通过if判断paymentDetails.method中是否存在paymentType为CREDIT_CARD的项，触发后续验证规则。
• 匹配与必填验证：
  1. 使用$data引用提取paymentDetails.method中所有paymentType为CREDIT_CARD的tokenizedCard值。
  2. 对customFields.paymentMethods中的每一项，若其tokenizedCard属于上述提取的集合，则强制要求cardNumber为必填项。
  3. 额外验证customFields.paymentMethods中必须包含匹配的tokenizedCard项，避免CREDIT_CARD的token在paymentMethods中不存在的情况。

注意事项 #

若Azure Logic Apps当前环境不支持$data关键字，可改用以下替代方案（仅当token值可提前枚举时适用）：
