如何管理多个JSON模式文件? [英] How to manage multiple JSON schema files?
问题描述
我正在尝试使用来自commonjs-utils的node.js + json-schema.js验证我的JSON API.只需一次验证就很容易,但是找不到正确的方法来管理多个架构文件以实现相互引用.
I'm trying to validate my JSON API using node.js + json-schema.js from commonjs-utils. Just single validation was easy but could not find right way how to manage multiple schema files to enable referencing each other.
假设我有两个模型&两个API.
Suppose that I got two Models & two APIs.
// book
{
"type": "object",
"properties": {
"title": { "type": "string" },
"author": { "type": "string" }
}
}
// author
{
"type": "object",
"properties": {
"first_name": { "type": "string" },
"last_name": { "type": "string" }
}
}
// authors API
{
"type": "array",
"items": { "$ref": "author" }
}
// books API: list of books written by same author
{
"type": "object",
"properties": {
"author": { "$ref": "author" }
"books": { "type": "array", "items": { "$ref": "book" } }
}
}
每个模式都应该划分为单独的文件并在线吗?还是可以合并为一个如下所示的单一架构文件?如果可能,如何引用本地架构?
Each schema should be divided in separate file and be online? Or Can I combine into single schema file like below? If it is possible, how can I reference local schema?
// single schema file {
"book": { ... },
"author": { ... },
"authors": { ... },
"books": { ... } }
推荐答案
在JSON模式中,您可以为每个文件放置一个模式,然后使用它们的URL(存储它们的位置)访问它们,或者使用
In JSON Schemas, you can either put a schema per file and then access them using their URL (where you stored them), or a big schema with id
tags.
这里是一个大文件:
{
"id": "#root",
"properties": {
"author": {
"id": "#author",
"properties": {
"first_name": {
"type": "string"
},
"last_name": {
"type": "string"
}
},
"type": "object"
},
// author
"author_api": {
"id": "#author_api",
"items": {
"$ref": "author"
},
"type": "array"
},
// authors API
"book": {
"id": "#book",
"properties": {
"author": {
"type": "string"
},
"title": {
"type": "string"
}
},
"type": "object"
},
// books API: list of books written by same author
"books_api": {
"id": "#books_api",
"properties": {
"author": {
"$ref": "author"
},
"books": {
"items": {
"$ref": "book"
},
"type": "array"
}
},
"type": "object"
}
}
}
然后,您可以将验证器引用到这些子模式之一(由id
定义).
You can then reference your validator to one of those sub schemas (which are defined with an id
).
从架构之外,这是
{ "$ref": "url://to/your/schema#root/properties/book" }
等效于此:
{ "$ref": "url://to/your/schema#book" }
…从内部等效于此:
… which is equivalent, from inside, to this:
{ "$ref": "#root/properties/book" }
或此(仍从内部):
{ "$ref": "#book" }
