对数组内某些对象属性的JSON模式条件检查

Question

我想通过AJV-JSON Schema验证或自定义关键字来做的（最好是与此结合）：数组可以具有1个或2个JSON对象，类型分别为'admin'和'guest'。 “ type”：“ guest”对象将始终存在，并且“ type”：“ admin”对象是可选的。

额外说明：

-对象本身将来可能包含附加属性和嵌套对象

-其他有效枚举是superadmin，admin，user和guest

-数组中的类型顺序为：superadmin，admin，user和guest。是否可以检查顺序？ （尽管它是可选的）

-“ guest”类型的对象将始终存在，并且将存在唯一类型的对象。如果重新出现任何对象类型（例如superadmin，admin，user和guest），则其为错误

//这是模式：

{
"type": "object",
"properties": {
  "type": "array",
  "items": {
    "type": "object",
    "properties": {
      "type": { "enum": ["guest", "admin"]
    },
    "rights": {"type": "string"},
    "hyperLink": {"type": "string", "format": "uri"}
    }
  }
  }
}

我需要在json中的某处添加'checkTypeAndValue'标志，以便我可以获取完整的JSON对象和相应的属性以进行程序化检查？

const checkTypeAndValue = function (schema, completeJSONObj) {
 //
};

ajv.addKeyword('checkTypeAndValue', {
  validate: checkTypeAndValue,
  errors: true
});

这是一些有效和无效的示例：

/Valid 1: As type is 'admin' and so 'rights' SHOULD NOT be in 'guest' object
{
  [
    {
      "type":"admin",
      "hyperLink": "http://www.someguest.com",
      "rights":"all"
    },
    {
      "type":"guest",
      "hyperLink": "http://www.someadmin.com"
    }
  ]
}

//Valid 2: You can have a SINGLE 'guest' object. 'admin' object is not required all the time
{
  [
    {
      "type":"guest",
      "hyperLink": "http://www.someadmin.com",
      "rights": "limited" //MANDATORY or REQUIRED Attribute
    }
  ]
}

//InValid
{
  [
    {
      "type":"admin",
      "hyperLink": "http://www.someguest.com",
      "rights":"all"
    },
    {
      "type":"guest",
      "hyperLink": "http://www.someadmin.com",
      "rights":"limited"
      //Error ==> As rights=all is there in 1st object, you cannot set 'rights' to any value including blank even having 'rights' attribute is not valid.
    }
  ]
}

这里是我需要解决的其他条件：

//Assuming admin object exist with rights....
if( type == admin && rights != ""){
  if(type == guest && rights attribute is there && rights != ""){
    //The 'guest' object will always be there....
    //error: guest 'rights' cannot have a value if type is 'admin' and rights is 'all' or any other value.
  }
}else{
   //Assuming mandatory guest object exist with rights....
   if(guest.rights does not exist OR guest.rights == "")
    //Error: 'rights' is MANDATORY attribute in guest block and error if its empty
   else 
    //Everything is fine
}

还有什么方法可以检查数组中只有一对特定类型的对象？例如：只有一种“访客”，“管理员”类型。错误，如果“访客”或“管理员”的类型不只一种]

//完整示例

{
  [
    {
      "type":"superadmin",
      "hyperLink": "http://www.superadmin.com"      
    },
    {
      "type":"admin",
      "hyperLink": "http://www.admin.com",
      "rights":"all"
    },
    {
      "type":"user",
      "hyperLink": "http://www.user.com"
    },
    {
      "type":"guest",
      "hyperLink": "http://www.guest.com"
    }
  ]
}

使用JSON模式执行此操作似乎有些棘手，但有可能。
