oneOf 对象的 Json Schema 示例

我试图通过构建一个验证两种不同对象类型的模式来了解其中一种是如何工作的.例如一个人(名字、姓氏、运动)和车辆(类型、成本).

Here are some sample objects:

{"firstName":"John", "lastName":"Doe", "sport": "football"}

{"vehicle":"car", "price":20000}

问题是我做错了什么，我该如何纠正它.以下是模式:

{
    "description": "schema validating people and vehicles", 
    "$schema": "http://json-schema.org/draft-04/schema#",
    "type": "object",
    "required": [ "oneOf" ],
    "properties": { "oneOf": [
        {
            "firstName": {"type": "string"}, 
            "lastName": {"type": "string"}, 
            "sport": {"type": "string"}
        }, 
        {
            "vehicle": {"type": "string"}, 
            "price":{"type": "integer"} 
        }
     ]
   }
}

当我try 在这个解析器中验证它时:

https://json-schema-validator.herokuapp.com/

I get the following error:

   [ {
  "level" : "fatal",
  "message" : "invalid JSON Schema, cannot continue\nSyntax errors:\n[ {\n  \"level\" : \"error\",\n  \"schema\" : {\n    \"loadingURI\" : \"#\",\n    \"pointer\" : \"/properties/oneOf\"\n  },\n  \"domain\" : \"syntax\",\n  \"message\" : \"JSON value is of type array, not a JSON Schema (expected an object)\",\n  \"found\" : \"array\"\n} ]",
  "info" : "other messages follow (if any)"
}, {
  "level" : "error",
  "schema" : {
    "loadingURI" : "#",
    "pointer" : "/properties/oneOf"
  },
  "domain" : "syntax",
  "message" : "JSON value is of type array, not a JSON Schema (expected an object)",
  "found" : "array"
} ]
