验证架构中的嵌套 JSON 属性

Question

这是我的 JSON 架构和 JSON 如下图底部所示，并使用 ajv 验证器支持 json 规范草案 7。

默认情况下，'science' 对象必须表示为：

//Default science object
{"type": "science", "rule": {"sciencePattern": {}}}

'rule' 和 'sciencePattern' 必须在那里。

但是，如果 'sciencePattern' 将包含其他属性（根据架构），则应启动以下验证：

如果存在默认科学对象，则 "arts" 对象中的 "scored" 属性应该是必需的。
如果 NESTED "scored" 数组属性存在于规则中：

{ "type": "science", "rule":{"sciencePattern":{"marks":{"scored":[10]}}} }

那么 "arts" 对象中的 "scored" 属性不应该是必需的。换句话说，如果有人在 "arts" 对象中指定 "scored" 属性，模式验证应该会报错，因为 "science" 对象中有一个 "scored" 属性可用。

        }
      }
    },
    {
      "type": "arts",
      "scored": 10 //This should complain as 'scored' is available above in science
    }
  ]
