jsonschema – 合并两个Json Schemas

2019年7月21日 355次阅读

我是
JSON和
JSON模式验证的新手.

我有以下架构来验证单个员工对象：

{
    "$schema":"http://json-schema.org/draft-03/schema#",
    "title":"Employee Type Schema",
    "type":"object",
    "properties": 
    {
        "EmployeeID": {"type": "integer","minimum": 101,"maximum": 901,"required":true},
        "FirstName": {"type": "string","required":true},
        "LastName": {"type": "string","required":true},
        "JobTitle": {"type": "string"},
        "PhoneNumber": {"type": "string","required":true},
        "Email": {"type": "string","required":true},
        "Address": 
        {
            "type": "object",
            "properties": 
            {
                "AddressLine": {"type": "string","required":true},
                "City": {"type": "string","required":true},
                "PostalCode": {"type": "string","required":true},
                "StateProvinceName": {"type": "string","required":true}
            }
        },
        "CountryRegionName": {"type": "string"}
    }
}

我有以下架构来验证同一员工对象的数组：

{
    "$schema": "http://json-schema.org/draft-03/schema#",
    "title": "Employee set",
    "type": "array",
    "items": 
    {
        "type": "object",
        "properties": 
        {
            "EmployeeID": {"type": "integer","minimum": 101,"maximum": 301,"required":true},
            "FirstName": {"type": "string","required":true},
            "LastName": {"type": "string","required":true},
            "JobTitle": {"type": "string"},
            "PhoneNumber": {"type": "string","required":true},
            "Email": {"type": "string","required":true},
            "Address": 
            {
                "type": "object",
                "properties": 
                {
                    "AddressLine": {"type": "string","required":true},
                    "City": {"type": "string","required":true},
                    "PostalCode": {"type": "string","required":true},
                    "StateProvinceName": {"type": "string","required":true}
                }
            },
            "CountryRegionName": {"type": "string"}
        }
    }
}

你能告诉我如何合并它们,这样我就可以使用一个单一的模式来验证单个员工对象或整个集合.谢谢.

最佳答案 (注意：这个问题也在
JSON Schema Google Group上被问到,这个答案是从那里改编的.)

使用“$ref”,你可以为你的数组提供类似的东西：

{
    "type": "array",
    "items": {"$ref": "/schemas/path/to/employee"}
}

如果你想要一个数组或一个项目,那么你可以使用“oneOf”：

{
    "oneOf": [
        {"$ref": "/schemas/path/to/employee"}, // the root schema, defining the object
        {
            "type": "array", // the array schema.
            "items": {"$ref": "/schemas/path/to/employee"}
        }
    ]
}

最初的Google网上论坛答案还包含一些使用“定义”来组织模式的建议,因此所有这些变体都可以存在于同一个文件中.
