这是我的JSON模式和JSON，如下面底部所示，并使用ajv验证程序支持json规范草稿7。
默认情况下，“科学”对象必须表示为：
//Default science object
{"type": "science", "rule": {"sciencePattern": {}}}
必须存在“规则”和“ sciencePattern”的位置。
但是，如果“ sciencePattern”即将包含其他属性（根据架构），则应执行以下验证：
{ "type": "science", "rule":{"sciencePattern":{"marks":{"scored":[10]}}} }
然后就不需要“艺术”对象中的“得分”属性。换句话说，如果有人在“艺术”对象中指定“得分”属性，则模式验证应该抱怨，因为“科学”对象中存在“得分”属性。
