PHP Json验证之一给出错误的Json，其中两个属性必须存在

Question

我无法根据模式验证json:

模式如下:

{
"type":"object",
"$schema": "http://json-schema.org/draft-03/schema",
"required":true,
"properties":{
    "tagId": {
            "type":"string",
            "id": "tagId",
            "required":true
    },
    "data_library": {
        "type":"object",
        "id": "data_library",
        "properties":{
            "info": {
                "type":"object",

                        "id": "contact",
                        "required":true
                    }                           
                }
            },
            "videos": {

            },
            "images": {
                "type":"array",

                "id": "info_book",
                "properties":{

                        "required":true

                        "id": "description",
                        "required":true
                    },
                    "agegroup": {
                        "type":"string",
                        "id": "agegroup",
                        "required":true
                    },
                    "author": {

                        "required":true
                    },
                    "publisher": {
                        "type":"string",
                        "id": "publisher",
                        "required":true
                    }       
                }
            },
            "videos": {
                "type":"array",
                "minitems": "0",
                "id": "videos",
                "items":
                {
                    "type":"string",
                    "required":true
                }
            },
            "images": {
                "type":"array",
                "minitems": "0",
                "id": "images",
                "items":
                {
                    "type":"string",
                    "required":true
                }
            }
        },
        "additionalProperties": false,
        "minProperties": 1
    }
},
"oneOf": [
    {"required": ["data_library"]},
    {"required": ["data_book"]}
]

}

现在的要求是在json文件中支持data_library或data_book。但是，当我尝试验证以下数据时:

{
    "tagId" : "DFGDASERTGSDG",
    "data_book" : {
            "info" :        {
                    "name" : "Pagdandi",
                    "location" : "Kaccha",
                    "description" : "..",
                    "starttime" : "..",
                    "endtime" : "..",
                    "contact" : ".."
            },
            "videos" :      [
                    "https://..."
            ],
            "images" :      [
                    "https://..."
            ]
    }

}

我得到以下错误:

Property: data_book.info.genre Msg:Is missing and it is requiredProperty: data_book.info.agegroup Msg:Is missing and it is requiredProperty: data_book.info.author Msg:Is missing and it is requiredProperty: data_book.info.publisher Msg:Is missing and it is required

我做错了什么?

Answer 1

您已经声明您正在使用JSON Schema Draft 3，但是oneOf和required在oneOf块中的使用是Draft 4。

如果您将所有的required关键字语句转换为Draft 4格式，那么您的模式将使用Draft 4验证器进行验证。

我不知道怎样才能使草案3中的所有东西都工作。我甚至不确定这是否可能。我认为在Draft 4中添加了oneOf这样的关键字和required这样的新格式，所以我们可以这样表达情况。

这是可以工作的Draft 4版本
