node.js - NodeJS JSON 架构验证不起作用

Question

我是 JSON Schema Validator 的新手，但我认为它非常强大。但是，我无法验证一个 JSON。

这是我的架构

 {
  title: "Example  Schema",
  type: "object",
  properties: {
    original_image:{
      type: "object",
      properties: {
        temp_id: {type: "string"},
        url: {type: "string"},
        scale:{
          type: "object",
          properties:{
            new_width: {type: "number"},
            new_height: {type: "number"}
          },
          required:["new_width","new_height"]
        }
      },
      required:["url","temp_id","scale"]
    }
  },
  required:["image"]
}

这是实际的 JSON:

{
  "original_image": {
    "temp_id": "this is my id",
    "scale": {
      "new_width": null,
      "new_height": 329
    }
  }
}

如您所见，“original_image”中的“url”属性不存在，但验证返回 true!而且，对于“new_width”，我将值设置为 null...并再次通过验证，所以我不知道我做错了什么。

看起来运行良好。控制台正确记录错误。这是我的 index.js

var Validator = require('jsonschema').Validator;
var v = new Validator();
var instance = {
  "original_image": {
    "temp_id": "this is my id",
    "scale": {
      "new_width": null,
      "new_height": 329
    }
  }
};
var schema = {
  title: "Example  Schema",
  type: "object",
  properties: {
    original_image:{
      type: "object",
      properties: {
        temp_id: {type: "string"},
        url: {type: "string"},
        scale:{
          type: "object",
          properties:{
            new_width: {type: "number"},
            new_height: {type: "number"}
          },
          required:["new_width","new_height"]
        }
      },
      required:["url","temp_id","scale"]
    }
  },
  required:["image"]
};
console.log(v.validate(instance, schema));
