JSON模式验证oneOf两个或allOf [英] JSON schema validate oneOf two or allOf

问题描述

我要验证以下json模式，我使用的是Ajv npm软件包.

i want to validate following json schema, i am using Ajv npm package.

{
    "email": "[e-mail]",
    "phone": "1112223334",
    "country_code": "91"
}

我只希望电子邮件，或者仅电话和国家/地区代码，或者应该有三个所有属性.

i want either email only, or phone and country_code only, or all of three properties should be there.

我尝试过oneOf，allOf，anyOf也尝试过嵌套主题，但是在某些情况下它可以工作，在某些情况下它不能工作.

i have tried oneOf, allOf, anyOf also have tried nested of theme but in some conditions its working and in some condidions its not working.

我尝试了以下代码

{
    "type": "object",
    "properties": {
        "email": {
            "type": "string",
            "format": "email",
            "maxLength": constants.LENGTHS.EMAIL.MAX
        },
        "phone": {
            "type": "string",
            "pattern": constants.REGEX.PHONE,
            "maxLength": constants.LENGTHS.PHONE.MAX
        },
        "country_code": {
            "type": "string",
            "pattern": constants.REGEX.COUNTRY_CODE,
            "maxLength": constants.LENGTHS.COUNTRY_CODE.MAX
        }
    },
    "anyOf": [
        {
            "required": ["email"],
        },
        {
            "required": ["phone", "country_code"],
        },
        {
            "required": ["email", "phone", "country_code"]
        },
    ],
    "additionalProperties": false

}

推荐答案

您需要:

"anyOf": [
    {
        "required": ["phone", "country_code"]
    },
    {
        "required": ["email"],
        "not": {
            "anyOf": [
                { "required": ["phone"] },
                { "required": ["country_code"] }
            ]
        }
    }
]

第一个子模式允许存在和不存在的电子邮件，这就是您想要的.

The first sub-schema allows for email both present and absent, which is what you want.

使用添加到JSON模式-06草稿(即将发布，将在Ajv 5.0.1-beta中提供)的关键字"propertyNames"关键字，您可以使其更简单(更易于阅读):

Using keyword "propertyNames" keyword that is added to JSON-schema draft-06 (to be published soon, available in Ajv 5.0.1-beta) you can make it a bit simpler (and easier to read):

"anyOf": [
    {
        "required": ["phone", "country_code"]
    },
    {
        "required": ["email"],
        "propertyNames": {"not": {"enum": ["phone", "country_code"] } }
    }
]

或者您可以使用 ajv-关键字(参见 https://github.com/json-schema-org /json-schema-spec/issues/213 ):

Or you can use custom keyword "prohibited" defined in ajv-keywords (see https://github.com/json-schema-org/json-schema-spec/issues/213):

"anyOf": [
    {
        "required": ["phone", "country_code"]
    },
    {
        "required": ["email"],
        "prohibited": ["phone", "country_code"]
    }
]
