空手道中的 PolyglotException，当某些 json 键具有连字符“-”时

Question

当 json 对象中的键包含连字符时，可能会导致空手道出现问题。这是一个例子 -

{
  "id": "1234",
  "type": "FICTION",
  "attribute": {
    "bookPrice": "10",
    "authorName": {
      "firstName": "Dean",
      "lastName": "Jones"
    },
    "links": {
      "get-book-by-id": {
        "href": "/v1/books/1234",
        "title": "get-book-by-id"
      }
    }
  }
}

在此示例中，键“get-book-by-id”由连字符分隔，当我尝试遍历此元素时，我收到如下错误 -

org.graalvm.polyglot.PolyglotException: ReferenceError: 'book' is not defined.
