可选属性json模式

Question

项目只需要order_type: ORDER，但我不能为特定情况下只需要这个属性的条件，也就是说，如果任何与ORDER不同的order_type没有项目，它可以被正确验证，但如果一个ORDER没有项目，我标记它是错误的。

试着在属性后面加上if来创建条件句，像这样

{
"$schema": "http://json-schema.org/draft-07/schema#",
"$id": "http://json-schema.org/draft-07/schema#",
"title": "Validaciones sobre el esquema Order",
"type": "object",
"properties": {
"warehouse_id": {
"type": [
"string"
]
},
"operation_type": {
"type": [
"string"
]
},
"order_id": {
"type": [
"number"
]
},
"items": {
"type": [
"array"
],
"minItems": 1,
"items": {
"type": [
"object"
],
"properties": {
"sku": {
"type": [
"string"
],
"minLength": 1,
"maxLength": 50
},
"quantity": {
"type": [
"integer"
],
"minimum": 1
}
},
"required": [
"sku",
"quantity"
],
"additionalProperties": false
}
},
"attributes": {
"type": [
"object"
],
"properties": {
"order_type": {
"type": [
"string"
],
"enum": [
"ORDER",
"TRANSFER",
"WITHDRAWAL",
"DISPOSAL",
"FRESH"
]
},
"etd": {
"type": [
"string"
],
"pattern": "^(\d{4})-(0[1-9]|1[0-2])-(0[1-9]|[12][0-9]|3[01])(?:T)(0[0-9]|1[0-9]|2[0-3]):(0[0-9]|1[0-9]|2[0-9]|3[0-9]|4[0-9]|5[0-9]):(0[0-9]|1[0-9]|2[0-9]|3[0-9]|4[0-9]|5[0-9])(?:Z)$"
},
"volume": {
"type": [
"integer", "null"
],
"minimum": 0
},
"typology": true
},
"required": [
"order_type"
],
"allOf": [
{
"if": {
"properties": {
"order_type": {
"const": "ORDER"
}
},
"required": [
"order_type",
"items"
]
},
"then": {
"properties": {
"order_type": true,
"etd": true,
"volume": true,
"typology": {
"type": [
"string", "null"
],
"enum": [
"CONVEYABLE",
"NON_CONVEYABLE"
]
}
},
"required": [
"order_type",
"etd"
],
"additionalProperties": false
}
},
{
"if": {
"properties": {
"order_type": {
"const": "TRANSFER"
}
},
"required": [
"order_type"
]
},
"then": {
"properties": {
"order_type": true,
"etd": true,
"volume": true
},
"required": [
"order_type",
"etd"
],
"additionalProperties": false
}
},
{
"if": {
"properties": {
"order_type": {
"const": "WITHDRAWAL"
}
},
"required": [
"order_type"
]
},
"then": {
"properties": {
"order_type": true,
"etd": true,
"volume": true
},
"required": [
"order_type",
"etd"
],
"additionalProperties": false
}
},
{
"if": {
"properties": {
"order_type": {
"const": "DISPOSAL"
}
},
"required": [
"order_type"
]
},
"then": {
"properties": {
"order_type": true,
"etd": true,
"volume": true
},
"required": [
"order_type",
"etd"
],
"additionalProperties": false
}
}
]
}
},
"allOf": [

{
"if": {
"properties": {
"order_type": {
"const": "ORDER"
}
},
"required": [
"order_type"
]
},
"then": {
"properties": {
"items": true,
"order_type": true,
"etd": true,
"volume": true
},
"required": [
"order_type",
"etd",
"items"
],
"additionalProperties": false
}
}

],
"required": [
"warehouse_id",
"operation_type",
"attributes"
],
"additionalProperties": false
}

这个请求应该被标记为不正确，因为没有任何必需的项目:

{
"warehouse_id": "ARTW01",
"operation_type": "outbound",
"order_id": 41789301078,
"attributes": {
"volume": 1350,
"etd": "2022-11-11T18:25:00Z",
"order_type": "ORDER"
}
}

下面是您所描述的删除了所有不相关部分的断言。关键在于if需要描述被检查值的嵌套路径。

{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"properties": {
"attributes": {
"type": "object",
"properties": {
"order_type": { "enum": ["ORDER", "TRANSFER", "WITHDRAWAL", "DISPOSAL", "FRESH"] }
},
"required": ["order_type"]
},
"items": { "type": "array" }
},
"allOf": [
{
"if": {
"type": "object",
"properties": {
"attributes": {
"type": "object",
"properties": {
"order_type": { "const": "ORDER" }
},
"required": ["order_type"]
}
},
"required": ["attributes"]
},
"then": { "required": ["items"] }
}
]
}
