我有一个如下所示的 json 响应..
[{
"views": [{
"groups": [{
"type": "static",
"tiles": [{
"context": "event",
"collection": "selo",
"tile_type": "static"
}
]
}
]
}, {
"groups": [{
"type": "static",
"tiles": [{
"context": "event",
"collection": "nitic",
"tile_type": "static"
}
]
}
]
}, {
"groups": [{
"type": "scrollable",
"tiles": [{
"name": "loca",
"location": "cal",
"tile_type": "person"
}, {
"name": "tom",
"location": "toc",
"tile_type": "person"
}
]
}
]
}
]
}
]
在这里，我必须验证每个 group 数组中的 tile 对象。基于 group 中的 type 键code> object tile 中的大小和关键元素
对象不同。例如，如果 type 键是 static，则 tile 对象的大小是 1，如果它的值为scrollable 它包含多个
tile 项。除此之外，tile 元素也不同。
对于 static tile，我必须验证以下关键元素的存在
"context"
"collection"
"tile_type"
对于 scrollable tile 我必须验证以下关键元素的存在
"name"
"location"
"tile_type"
基于这些，我已经使用这样的开关定义了一个模式，但模式验证不起作用。我也尝试使用 anyOf 而不是 switch 关键字。(Iam使用 draft7 版本)
模式定义
"switch": [
{
"if": {
"properties": {
"tile_type": {
"enum": [
"static"
]
}
},
"required": [
"context",
"collection",
"tile_type"
]
}
},
{
"if": {
"properties": {
"tile_type": {
"enum": [
"person"
]
}
},
"required": [
"name",
"location",
"tile_type"
]
}
}
]
尝试过 anyOF
"anyOf": [{
"properties": {
"tile_type": {
"enum": [
"static"
]
}
},
"required": [
"context",
"collection",
"tile_type"
]
}, {
"properties": {
"tile_type": {
"enum": [
"person"
]
}
},
"required": [
"name",
"location",
"tile_type"
]
}
]
使用 anyOf 时观察到的错误
Found 2 error(s)
Message:
Required properties are missing from object: context, collection.
Schema path:

执行此操作的任何解决方案？
下面是更新的部分
在响应中，有时一些 tile 数据包含键 errorText 和 errorCode 。
[{
"views": [{
"groups": [{
"type": "static",
"tiles": [{
"context": "event",
"tile_type": "static"
}
]
}
]
}, {
"groups": [{
"type": "static",
"tiles": [{
"context": "event",
"collection": "nitic",
"tile_type": "static"
}
]
}
]
}, {
"groups": [{
"type": "scrollable",
"tiles": [{
"name": "loca",
"location": "cal",
"tile_type": "person"
}, {
"errorText":"Tile failure",
"errorCode":1,
"tile_type": "person"
},
{
"errorText":"Tile not generated",
"errorCode":2,
"tile_type": "person"
}
]
}
]
}
]
}
]
在这种情况下，我在现有的 oneOf 数组中添加了一个额外的属性，如下所示。
但它不起作用。我的模式定义有什么问题
{
"properties": {
"type": {
"const": "scrollable"
},
"tiles": {
"type": "array",
"minItems": 2,
"items": {
"properties": {
"errorText": {
"const": ["Tile failure", "Tile not generated"]
}
},
"required": [
"errorText",
"errorCode",
"tile_type"
]
}
}
}
}
进行架构验证时的错误消息:
Message:
Value "static" does not match const.
Schema path:
#/items/properties/views/items/properties/groups/items/oneOf/2/properties/type/const
Message:
Value "static" does not match const.
Schema path:
#/items/properties/views/items/properties/groups/items/oneOf/1/properties/type/const
最佳答案
这是一个适用于您给定的 JSON 实例的架构，具有以下验证规则:
类型可以是static 或 scrollable
如果类型是static，tiles 数组中最多一个项目，并且对象属性必须是context、collection 和tile_type.
如果类型是scrollable，tiles数组中至少有两项，对象属性必须是name，location 和 tile_type。
可滚动 磁贴中的项目必须是唯一的。
In addition to this the tile elemnts also different
抱歉，JSON Schema 无法做到这一点。
还使用与您使用的相同的在线验证器进行了测试。
