只允许在JSON模式中声明的属性 [英] Only allow properties that are declared in JSON schema

问题描述

我正在使用json-schema，并且只想允许在此文件中声明的属性通过验证.例如，如果用户在其json对象中传递名称"属性，则该模式将失败，因为此处没有将名称"作为属性列出.

I am using json-schema and wanting to only allow properties that are declared in this file to pass validation. For instance if a user passes a "name" property in their json object it will fail this schema because "name" is not listed here as a property.

是否有一些类似于"required"的功能仅允许列出的属性通过?

Is there some function similar to "required" that will only allow the listed properties to pass?

{
"$schema": "http://json-schema.org/draft-04/schema#",
"title": "Accounting Resource - Add Item",
"type": "object",
"properties": {
    "itemNumber": {
        "type":"string",
        "minimum": 3
    },
    "title": {
        "type":"string",
        "minimum": 5
    },
    "description": {
        "type":"string",
        "minimum": 5
    }
},
"required": [
    "itemNumber",
    "title",
    "description"
]
}

推荐答案

我相信将additionalProperties设置为false可以实现此目的.请参见此处

I believe what you need to do to achieve this is set additionalProperties to false. See the specification here
