引用json模式数组中的多个类型

Question

我试图在json模式v7中定义对象的数组属性，但验证不起作用。如何正确引用要在数组中使用的多个类型定义？在这里，目录的数组可以包含更多的目录或路由：

{
"$schema": "http://json-schema.org/draft-07/schema#",
"$id": "RootDirectory",
"title": "Directory",
"description": "Build a directory for javascript app routing.",
"type": "object",
"definitions": {
"Route": {
"type": "object",
"description": "A simple endpoint declaration.",
"additionalProperties": false,
"properties": {
"path": {
"type": "string",
"description": "An endpoint without forward slashes.",
"examples": ["welcome"],
"minLength": 1
},
"variableSuffix": {
"description": "A string that is appended to the path variable name during build.",
"type": "string"
}
},
"required": ["path"]
},
"Directory": {
"type": "object",
"description": "Contains child directories or routes for recursive tree building.",
"additionalProperties": false,
"properties": {
"path": {
"type": "string",
"description": "An endpoint without forward slashes.",
"examples": ["welcome"],
"minLength": 1
},
"variableSuffix": {
"description": "A string that is appended to the path variable name during build.",
"type": "string"
},
"childNodes": {
"minItems": 1,
"type": "array",
"description": "An array of routes, linkedRoutes, subDirectories, or linkedSubDirectories.",
"contains": {
"type": "object",
"oneOf": [
{"$ref": "#/definitions/Route"},
{"$ref": "#/definitions/Directory"}
]
}
}
},
"required": ["path", "childNodes"]
},
},
"properties": {
"directories":{
"type": "array",
"contains": {
"type": "object",
"allOf": [{"$ref": "#/definitions/Directory"}]
},
"minItems": 1
},
"rootPath": {
"type": "string",
"default": ""
}
},
"required": ["directories"]
}

例如，这是有效的，不应该是，因为它包含一个具有无效属性的对象：

{
"rootPath": "api",
"directories": [
{
"path": "a",
"childNodes": [
{
"path": "a",
"variableSuffix": "s"
},
{
"invalidProperty" : "a"
}
]
}
]
}

是否存在不允许使用属性/directories/0/childNodes/1/invalidProperty的问题？架构并没有声明childNodes中的所有数组项都必须有效——它只指定childNodes必须包含一个有效项，而项#0确实有效，因此整个架构有效。

要断言childNodes中的所有项必须有效，请将/definitions/Directory/properties/childNodes/contains处的contains更改为items——items关键字指定必须针对全部数组项验证的架构，而contains仅断言必须验证至少一个数组项。
