我具有以下模式,该模式“有效”,但并未强制执行所有必需的规则。
我得到带有一系列具有 templateType 和 data 属性的问题的JSON。每种类型都有不同的模板,并且类型必须适合该模板(否则客户端不知道如何布局数据)。
该模式将 templateType 验证为枚举,并且数据适合其中一个模板,但是类型和数据结构之间没有关联(例如,我可以获取 templateType yesNo和multiSelect的数据结构。
我希望它验证 templateType 是否与数据结构匹配。我无法更改生成的JSON的格式,只能更改可对其进行验证的架构。我看过的所有问题似乎都没有提供解决方案。
要获取帮助,可以将模式粘贴到http://jeremydorn.com/json-editor/的编辑器中,该编辑器根据选择和输入到表单中的数据从模式和JSON数据生成表单。

答案 0 :(得分:1)
您是否考虑过在架构中使用if
,then
,else
关键字?它们是JSON Schema draft-07
它看起来像这样:
{
"definitions": {
"question": {
"type": "array",
"title": "Question",
"items": {
"$ref": "#/definitions/template"
}
},
"template": {
"type": "object",
"title": "Question template",
"required": ["templateType","data"],
"properties": {
"templateType": {
"type": "string",
"enum": ["yesNo","multiSelect"]
},
"data": {
"if": { "properties": { "templateType": { "pattern": "^yesNo$" } } },
"then": { "$ref": "#/definitions/yesNo" },
"else": { "$ref": "#/definitions/multiSelect" }
}
}
},
"yesNo": {
"type": "object",
"title": "Yes/No question",
"additionalProperties": false,
"properties": {
"label": {
"type": "string"
}
}
},
"multiSelect": {
"type": "array",
"title": "Multi-select question",
"items": {
"type": "string",
"title": "Label for option",
"additionalProperties": false
}
}
},
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "array",
"items": {
"$ref": "#/definitions/question"
}
}
如果您的验证人不支持if/then/else
,则可以选择以下替代方法:
{
"definitions": {
"question": {
"type": "array",
"title": "Question",
"items": {
"$ref": "#/definitions/template"
}
},
"template": {
"type": "object",
"title": "Question template",
"required": ["templateType","data"],
"anyOf": [
{
"properties": {
"templateType": { "type": "string", "pattern": "yesNo" },
"data": { "$ref": "#/definitions/yesNo" }
}
},
{
"properties": {
"templateType": { "type": "string", "pattern": "multiSelect" },
"data": { "$ref": "#/definitions/multiSelect" }
}
}
]
},
"yesNo": {
"type": "object",
"title": "Yes/No question",
"additionalProperties": false,
"properties": {
"label": {
"type": "string"
}
}
},
"multiSelect": {
"type": "array",
"title": "Multi-select question",
"items": {
"type": "string",
"title": "Label for option",
"additionalProperties": false
}
}
},
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "array",
"items": {
"$ref": "#/definitions/question"
}
}
