使用任意键进行JSON模式验证 [英] JSON schema validation with arbitrary keys

问题描述

我正在使用validictory来验证附加的JSON数据和架构. 到目前为止工作.

I am using validictory for validating the attached JSON data and schema. Working so far.

但是，数据字典可以具有任意字符串键(但'bp'除外).模式中的键"bp"是硬编码的，它可以是给定列表中的字符串(字符串枚举).如何在此处为字典的第一级"添加枚举定义.

However the data dictionary can have arbitrary string keys (others than 'bp' but). The key 'bp' in the schema here is hard-coded...it can be a string from a given list (enum of string). How do I add the enum definition here for the "first level" of the dict.

import json
import validictory

data = {'bp': [{'category': 'bp',
         'created': '2013-03-08T09:14:48.148000',
         'day': '2013-03-11T00:00:00',
         'id': 'dc049c0e-d19a-4e3e-93ea-66438a239712',
         'unit': 'mmHg',
         'value': 147.0,
         'value2': 43.0}]}


schema = {
    "type":"object",
    "properties":{
        "bp": {
            "type":"array",
            "required":False,
            "items":
                {
                    "type":"object",
                    "required":False,
                    "properties":{
                        "category": {
                            "type":"string",
                            "default": "bp",
                            "required":False
                        },
                        "created": {
                            "type":"string",
                            "default": "2013-03-08T09:14:48.148000",
                            "required":False
                        },
                        "day": {
                            "type":"string",
                            "default": "2013-03-11T00:00:00",
                            "required":False
                        },
                        "id": {
                            "type":"string",
                            "default": "dc049c0e-d19a-4e3e-93ea-66438a239712",
                            "required":False
                        },
                        "unit": {
                            "type":"string",
                            "default": "mmHg",
                            "required":False
                        },
                        "value2": {
                            "type":"number",
                            "default":43,
                            "required":False
                        },
                        "value": {
                            "type":"number",
                            "default":147,
                            "required":False
                        }
                    }
                }


        }
    }
}

validictory.validate(data,schema)

推荐答案

这完全取决于您要执行的操作.

It depends on exactly what you're trying to do.

如果您希望使用相同的规范，但要获得一系列属性，则可以抽象出定义:

If you want the same specification, but for a range of properties, you can abstract out the definition:

{
    "type": "object",
    "properties": {
        "bp": {"$ref": "#/definitions/categoryList"},
        "foo": {"$ref": "#/definitions/categoryList"},
        "bar": {"$ref": "#/definitions/categoryList"}
    },
    "definitions": {
        "categoryList": {...}
    }
}

如果希望任何属性遵循该架构，则可以使用additionalProperties:

If you want any properties to follow that schema, you can use additionalProperties:

{
    "type": "object",
    "additionalProperties": {...}
}

或一系列属性(由模式匹配)-例如，任何小写字母:

Or a range of properties (matched by a pattern) - for instance, anything lower-case:

{
    "type": "object",
    "patternProperties": {
        "^[a-z]+$": {...}
    }
}

如果要限制可以定义的属性的数量，则可以使用"maxProperties"(仅标准版v4):

If you want to limit the number of properties that can be defined, then you can use "maxProperties" (v4 of the standard only):

{
    "type": "object",
    "additionalProperties": {...},
    "maxProperties": 1
}

P.S. -在标准的v4中，必需"是一个数组.实际上，即使在v3中，"required"也默认为false，因此您的示例根本不需要它.

P.S. - in v4 of the standard, "required" is an array. In fact, even in v3, "required" defaults to false, so your example doesn't need it at all
