如何从HATEOAS中的集合中删除链接的资源？

Question

如何使用HATEOAS从对象集合中删除资源？

PUT将设置集合。补丁将允许部分更新/添加。

但是我怎么做部分更新/删除呢？

我真的需要发布整个uri-list减去1才能删除单个项目吗？

以此对象为例：

{
  "name": "Bob Test",
  "description": "this is the descript",
  "_links": {
    "self": {
      "href": "http://localhost/example/1"
    },
    "example": {
      "href": "http://localhost/example/1"
    },
    "citations": {
      "href": "http://localhost/example/1/citations"
    },
   }
}

该对象有许多引用(集合)：

{
  "_embedded": {
    "citations": [
      {
        "content": "asdfasdf",
        "anchor": null,
        "_links": {
          "self": {
            "href": "http://localhost/citations/1"
          },
          "citation": {
            "href": "http://localhost/citations/1"
          },
          "bioMarker": {
            "href": "http://localhost/citations/1/example"
          }
        }
      },
      {
        "content": "c2",
        "anchor": "prf",
        "_links": {
          "self": {
            "href": "http://localhost/citations/2"
          },
          "citation": {
            "href": "http://localhost/citations/2"
          },
          "bioMarker": {
            "href": "http://localhost/citations/2/example"
          }
        }
      }
    ]
  },
  "_links": {
    "self": {
      "href": "http://localhost/example/1/citations"
    }
  }
}

现在假设我想要删除http://localhost/citations/2，如何从http://localhost/example/1/citations集合中删除此特定项？

从响应中获取内容类型，并在请求头部"Accept“中发送。通常是"application/xxxxx+json“
