6. 错误响应体 (Error Response Body)

某些非应答响应可能返回包含更具描述性信息的实体主体。

该响应的基本结构是一个对象类，包含一个必需的错误代码号（对应于 HTTP 响应代码），后跟一个名为 "title" 的可选字符串和一个名为 "description" 的可选字符串数组。

这是常见响应体的示例。

{
  "errorCode": 418,
  "title": "Your Beverage Choice is Not Available",
  "description":
  [
    "I know coffee has more ummppphhh.",
    "Sorry, dude!"
  ]
}

这是包含 rdapConformance 和 notices 数据结构的常见响应体示例：

{
  "rdapConformance" :
  [
    "rdap_level_0"
  ],
  "notices" :
  [
    {
      "title" : "Beverage Policy",
      "description" :
      [
        "Beverages with caffeine for keeping horses awake."
      ],
      "links" :
      [
        {
          "value" : "https://example.net/ip/192.0.2.0/24",
          "rel" : "alternate",
          "type" : "text/html",
          "href" : "https://www.example.com/redaction_policy.html"
        }
      ]
    }
  ],
  "lang" : "en",
  "errorCode": 418,
  "title": "Your beverage choice is not available",
  "description":
  [
    "I know coffee has more ummppphhh.",
    "Sorry, dude!"
  ]
}
