JSON模式 - 具有相同数据类型的对象

时间:2017-12-14 09:05:25

标签: json node.js jsonschema

我生成了以下JSON:

{
 "someString" : "example",
 "obj1" : {
     "opt1" : 1,
     "opt2" : 1,
     "opt3" : "aaa"
 },
 "obj2" : {
     "opt1" : 55,
     "opt2" : 55,
     "opt3" : "bbb"
 }
}

并且会有更多具有相同数据类型的对象(obj1,obj2,obj3,obj4,...)(opt1,opt2,opt3)

现在我想为此创建架构,但我不知道如何在架构中组合所有这些对象。

编辑:

我创建了架构:

root: {
    "type" : "object",
    "oneOf" : [
        {
        "properties" : {
            "someString" : { "type" : "string" }
        },
        "patternProperties" : { "^.*$" : { "$ref" : "./schemas/myPatternProperties.json#" } },
        "additionalProperties" : false }
        }
    ]
}

和myPatternProperties.json看起来:

{
    "type" : "object",
    "properties" : {
        "opt1" : { "type" : "number" },
        "opt2" : { "type" : "number" },
        "opt3" : { "type" : "string" },
    }
    "required" : [ "opt1", "opt2", "opt3" ]
}

是否有任何错误,因为我生成的JSON仍未被识别为此架构类型。

据我所知,你的问题是describe object with a lot of properties with the same type and some naming rules。要解决此问题,您必须指定patternProperties部分

{
    "patternProperties": {
        "^(/[^/]+)+$": { "$ref": "http://some.site.somewhere/entry-schema#" }
}

该构造为属性指定pattern to match。示例how to use patternProperties详情请见specification

实际上,完整的方案必须是那样的

{
    "$schema": "http://json-schema.org/draft-06/schema#",
    "type": "object",
    "properties": {
        "someString": {
            "type": "string"
        }
    },
    "patternProperties": {
        "^obj([0-9]+)$": {
            "$ref": "#/definitions/objEntity"
        }
    },
    "additionalProperties": false,
    "required": [ "someString" ],

    "definitions": {
        "objEntity": {
            "type": "object",
            "properties": {
                "opt1": { "type": "number" },
                "opt2": { "type": "number" },
                "opt3": { "type": "string" }
            },
            "required": ["opt1", "opt2", "opt3"]
        }
    }
}

当然,您可以将该方案拆分为多个文件,并将链接更改为类型定义。
