【问题标题】：JSON document fails validation on JSON SchemaJSON 文档在 JSON Schema 上的验证失败
【发布时间】：2017-01-30 15:19:51
【问题描述】：

下面的 Json 模式和 Json 文档都是有效的 json。只是我无法获得与 json 架构相关的有效 Json 文档。

我收到错误消息：不应该有其他属性

Json 架构

  "$schema": "http://json-schema.org/draft-04/schema#",

JSON 文档

[

    "title": "Kung Fu Panda",
    "release_date": "01-01-2001",
    "video": "",
    "IMDBURL": "link.com",

      "abc",
      "def"

    }
  }
]

【问题讨论】：

标签： json jsonschema json-schema-validator

【解决方案1】：

架构中缺少"users" 属性，因此它是一个附加属性，因此它违反了"additionalProperties": false 设置。

如果您在架构中定义 "users" 属性，那么您的文档将是有效的。

【讨论】：

请检查它是否存在，滚动到底部。
在您的 JSON 对象中，“用户”是“电影”的一部分，因此在您的架构中，您必须在电影架构中添加“用户”作为字段

【解决方案2】：

问题在于附加属性的位置。因为用户是具有大量对象的数组类型。假设项目的属性具有附加属性，而不是包装器“用户”：{}，而是“项目”：{}
