Javascript 发布JSON时出现ValidationError

我为作者提供了以下模式：

module.exports = {
  "id": "Author",
  "properties": {
    "name": {
      "type": "string",
      "description": "The full name of the author"
    },
    "description": {
      "type": "string",
      "description": "A small bio of the author"
    },
    "books": {
      "type": "array",
      "description": "The list of books published on at least one of the stores by this author",
      "items": {
        "$ref": "Book"
      }
    },
    "website": {
      "type": "string",
      "description": "The website url of the author"
    },
    "avatar": {
      "type": "string",
      "description": "The url of the avatar of this author"
    }
  }
}

当我发布到以创建新作者时，出现以下错误：

错误：找到InternalServerError类型的错误：ValidationError:books:对路径books处的值['TheTwits'，'TheBFG']转换到数组失败

这是我发布的JSON

{
    "name": "Roald Dahl",
    "description": "Writes childrens novels",
    "books": [
        "The Twits",
        "The BFG"
    ],
    "website": "www.roalddahl.com",
    "avatar": "https://www.natgeokids.com/wp-content/uploads/2016/11/Roald-Dahl-1-1.jpg"
}

据我所知，这个JSON是正确的。该错误似乎表明books数组存在问题。是这样吗？如果是，我该如何解决

正在添加书本架构：

module.exports = {
  "id": "Book",
  "properties": {
    "title": {
      "type": "string",
      "descrtiption": "The title of the book"
    },
    "authors": {
      "type": "array",
      "description": "List of authors of the book",
      "items": {
        "$ref": "Author"
      }
    },
    "isbn_code": {
      "type": "string",
      "description": "The stores where clients can buy this book"
    },
    "stores": {
      "type": "array",
      "description": "The stores where clients can buy this book",
      "items": {
        "type": "object",
        "properties": {
          "store": {
            "$ref": "Store"
          },
          "copies": {
            "type": "integer"
          }
        }
      }
    },
    "genre": {
      "type": "string",
      "description": "Genre of the book",
    },
    "description": {
      "type": "string",
      "description": "Description of the book"
    },
    "reviews": {
      "type": "array",
      "items": {
        "$ref": "ClientReview"
      }
    },
    "price": {
      "type": "number",
      "minimum": 0,
      "description": "The price of this book"
    }
  }
}

您正在将JSON与books字段一起作为字符串数组发布，因此您的validator对象应该指定：

items: { type: "string" },

items:{$ref:Book}是什么意思？我使用在线工具进行测试，如果没有，数据是有效的$ref在JSON模式中非常好；假设一个Book对象有一个模式，那么OP在这里使用的ref表示数组将包含Book对象。但是在JSON文档中，OP使用的是字符串，而不是book对象。这段代码来自使用Node.js进行REST API开发的书籍。我正在学习，所以有一些事情我不确定$参考。记住这一点，我的JSON可能错误地在书中使用了字符串。假设它应该使用book对象，我将如何更改JSON以使用它？我需要先加书吗？
