NodeJS JSON 模式验证不工作

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
    }
  }
}

因此，正如您所见，"original_image" 中的 "url" 属性不存在，但验证 returns 为真！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。

它似乎工作正常。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));

Answer 2

如果您将条件设置为 required:["url","temp_id","scale"] ，则有效负载中需要所有三个属性，但您的有效负载中似乎缺少 url 。如果你希望 url 是可选的，那么，不要把它放在 required 约束中。如果是这种情况，验证器还会返回错误 message.It returns missing parameters/properties。
