我试图通过构建一个验证两种不同对象类型的模式来弄清楚 oneOf 是如何工作的。例如一个人(名字、姓氏、运动)和车辆(类型、成本)。
以下是一些示例对象:
{"firstName":"John", "lastName":"Doe", "sport": "football"}
{"vehicle":"car", "price":20000}
问题是我做错了什么以及如何解决它。这是架构:
{
"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"}
}
]
}
}
当我尝试在这个解析器中验证它时:
https://json-schema-validator.herokuapp.com/
我收到以下错误:
[ {
"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"
} ]
最佳答案
试试这个:
{
"description" : "schema validating people and vehicles",
"type" : "object",
"oneOf" : [
{
"type" : "object",
"properties" : {
"firstName" : {
"type" : "string"
},
"lastName" : {
"type" : "string"
},
"sport" : {
"type" : "string"
}
}
},
{
"type" : "object",
"properties" : {
"vehicle" : {
"type" : "string"
},
"price" : {
"type" : "integer"
}
},
"additionalProperties":false
}
]
}
