我有一個帶有陣列的 JSON 配置"specs"，具有許多不同型別的"path"屬性。該"kind"屬性是變體的選擇器。
我想限制驗證不允許添加屬性。在 JSON 示例中，屬性"noAllowedInt"和"notAllowedObject" 必須報告驗證錯誤。
如何將此規則添加到 JSON 架構？
{
"specs": [
{
"id": 12,
"label": "Serial",
"path": {
"kind": "serial",
"speed": 9600,
"parity": "even"
}
},
{
"id": 13,
"label": "Memory",
"path": {
"kind": "memory",
"storage": "permanent",
"location": "external"
},
"noAllowedInt": 42,
"notAllowedObject": {
"value": 3.1415
}
}
]
}
有兩個 Json Schema 來驗證這一點，一個簡單的一個和一個"definitions"
簡單的 JSON 模式：
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"additionalProperties": false,
"properties": {
"specs": {
"type": "array",
"items": {
"type": "object",
"additionalProperties": true,
"properties": {
"id": {
"type": "integer"
},
"label": {
"type": "string"
}
},
"required": [
"id",
"label"
],
"oneOf": [
{
"type": "object",
"properties": {
"path": {
"type": "object",
"additionalProperties": false,
"properties": {
"kind": {
"type": "string",
"enum": [
"serial"
]
},
"speed": {
"type": "integer"
},
"parity": {
"type": "string"
}
},
"required": [
"kind"
]
}
}
},
{
"type": "object",
"properties": {
"path": {
"type": "object",
"additionalProperties": false,
"properties": {
"kind": {
"type": "string",
"enum": [
"memory"
]
},
"storage": {
"type": "string"
},
"location": {
"type": "string"
}
},
"required": [
"kind"
]
}
}
}
]
}
}
},
"required": [
"specs"
]
}
JSON模式與"definitions"
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"additionalProperties": false,
"properties": {
"specs": {
"type": "array",
"items": {
"type": "object",
"additionalProperties": true,
"properties": {
"id": {
"type": "integer"
},
"label": {
"type": "string"
}
},
"required": [
"id",
"label"
],
"oneOf": [
{
"$ref": "#/definitions/PathKindSerialType"
},
{
"$ref": "#/definitions/PathKindMemory"
}
]
}
}
},
"required": [
"specs"
],
"definitions": {
"PathKindSerialType": {
"type": "object",
"additionalProperties": true,
"properties": {
"path": {
"type": "object",
"additionalProperties": false,
"properties": {
"kind": {
"type": "string",
"enum": [
"serial"
]
},
"speed": {
"type": "integer"
},
"parity": {
"type": "string"
}
},
"required": [
"kind"
]
}
}
},
"PathKindMemory": {
"type": "object",
"additionalProperties": true,
"properties": {
"path": {
"type": "object",
"additionalProperties": false,
"properties": {
"kind": {
"type": "string",
"enum": [
"memory"
]
},
"storage": {
"type": "string"
},
"location": {
"type": "string"
}
},
"required": [
"kind"
]
}
}
}
}
}
uj5u.com熱心網友回復：
我想您需要將路徑定義作為屬性保留在 specs 陣列級別。這將是我的建議：
{
"$schema": "http://json-schema.org/draft-04/schema#",
"description": "JSON schema generated with JSONBuddy https://www.json-buddy.com",
"type": "object",
"additionalProperties": false,
"properties": {
"specs": {
"type": "array",
"items": {
"type": "object",
"additionalProperties": false,
"properties": {
"id": {
"type": "integer"
},
"label": {
"type": "string"
},
"path": {
"oneOf": [
{
"$ref": "#/definitions/PathKindSerialType"
},
{
"$ref": "#/definitions/PathKindMemory"
}
]
}
},
"required": [ "id", "label" ]
}
}
},
"required": [ "specs" ],
"definitions": {
"PathKindSerialType": {
"type": "object",
"additionalProperties": false,
"properties": {
"kind": {
"type": "string",
"enum": [ "serial" ]
},
"speed": {
"type": "integer"
},
"parity": {
"type": "string"
}
},
"required": [ "kind" ]
},
"PathKindMemory": {
"type": "object",
"additionalProperties": false,
"properties": {
"kind": {
"type": "string",
"enum": [ "memory" ]
},
"storage": {
"type": "string"
},
"location": {
"type": "string"
}
},
"required": [ "kind" ]
}
}
}
