问题描述
我最近开始为我们的一个项目探索 JSON Schema。用例非常简单,经过大量谷歌搜索后,我仍然无法使其工作。其实我在这里有点失落。 .这是我试过的https://json-schema.org/understanding-json-schema/structuring.html
我的common_data_schema.json
{
"deFinitions": {
"sp_common_data": {
"type": "object","properties": {
"os_ip": {
"type": "string","format": "ipv4"
},"os_user": {
"type": "string"
},"os_pwd": {
"type": "string"
},"remote_os": {
"default": "Windows","enum": [
"Linux","Windows"
]
}
},"required": [
"os_ip","os_user","os_pwd","remote_os"
]
} },"type": "object","properties": {
"sp_must_data":{ "$ref": "#/deFinitions/sp_common_data" }
}
}
现在我的 server_update.json
架构,我想在其中验证 common_data_schema
+ new
properties
{
"$schema": "http://json-schema.org/draft-07/schema#","properties": {
"sp_must_data":{"$ref": "common_data_schema.json#sp_common_data"},"file": {
"type": "string"
}
}
}
但是当我尝试使用 server_update.json
https://python-jsonschema.readthedocs.io/en/stable/ 验证 jsonschema
架构时,它不考虑 $ref
架构 common_data_schema.json
定义
schema loader
逻辑很简单,我所有的架构都驻留在 artifacts
文件夹中
import json
from pathlib import Path
# Location for the test artifacts
artifacts = Path(__file__).parent.parent.joinpath("artifacts").resolve()
def load_schema(filename):
data = open(Path(artifacts).joinpath(filename),"r").read()
return json.loads(data)
下面的 json schema
验证逻辑
from typing import Dict,List
from jsonschema import Draft7Validator,exceptions
def validate(schema: Dict,instance: Dict) -> List[exceptions.ValidationError]:
"""
Validate the instance using the specified schema
:param schema: Schema object
:param instance: instance Object
:return: List of errors during validation
"""
validator = Draft7Validator(schema=schema)
return list(validator.iter_errors(instance))
