Question

我正在使用nodejs中的REST Web服务器，我正在考虑使用Collection+JSON作为超媒体类型来实现它。

但是我不明白是否有可能在集合1到n的关系中表示。所以，例如，如果我有一个收集篮子，可以让篮子内的物品指向其他定义的收藏品吗？

Answer 1

您可以使用collection link relation，其描述为：

指代表示其集合的资源当前资源是会员。

这似乎符合您的需要。

使用传统的电子商务示例，以下是如何构建产品的集合-JSON端点。请注意，您的客户端应按rel-tag分组。您的rel标签列表是您的合同＆＃34;与您的客户。＆＃34;此rel标签始终表示。＆＃34;

"collection":
{
  "href": "/products/1234.json",
  "items":
  [
    {
      "name": "name",
      "value": "10 Speed Bike"
    }
    {
      "name": "manufacturer",
      "value": "Schwin"
    }
    {
      "name": "price",
      "value": 150.00
    }
  ],
  "links":
  [
    {
      "href": "/products/1234/attachments/flier.pdf",
      "rel": "attachment",
      "prompt": "Flier from the Manufacturer",
      "render": "link"
    },
    {
      "href": "/products/1234/attachments/specs.pdf",
      "rel": "attachment",
      "prompt": "Spec Sheet from Manufacturer",
      "render": "link"
    },
    {
      "href": "/products/1234/attachments/warranty.pdf",
      "rel": "attachment",
      "prompt": "Limited Lifetime Warranty",
      "render": "link"
    },
    {
      "href": "/store/attachments/returns.pdf",
      "rel": "attachment",
      "prompt": "Our Return Policy",
      "render": "link"
    },
    {
      "href": "/images/1235478324.png",
      "rel": "product-image",
      "prompt": "A Schwin 10-speed bike in red",
      "render": "image"
    },
    {
      "href": "/images/1235478355.png",
      "rel": "product-image",
      "prompt": "A girl riding a 10-speed bike.",
      "render": "image"
    },
    {
      "href": "/images/1235478385.png",
      "rel": "product-image",
      "prompt": "A grandma watching grandkids ride bicycles.",
      "render": "image"
    },
    {
      "href": "/images/1235478545.png",
      "rel": "swatch",
      "prompt": "Radiant Red",
      "render": "image"
    },
    {
      "href": "/images/1235478545.png",
      "rel": "swatch",
      "prompt": "Brilliant Blue",
      "render": "image"
    },
    {
      "href": "/images/1235478588.png",
      "rel": "swatch",
      "prompt": "Stunning Silver",
      "render": "image"
    },
    {
      "href": "/blog/2014/07/26",
      "rel": "content",
      "prompt": "Our store now sells Schwin bicycles!",
      "render": "link"
    },
    {
      "href": "/manufacturers/schwin",
      "rel": "manufacturer",
      "prompt": "Schwin",
      "render": "link"
    },      ]
}

在这个例子中，客户端会知道＆＃34; swatch＆＃34; rel-tag意味着它应该显示颜色样本部分...每个＆＃34; rel-tag的一个样本。＆＃34;如果有1个样本与许多样本，您的客户甚至可能会以不同的方式呈现。

你想要扩展集合+ JSON（I've extended it extensively）可能会被原谅。集合+ JSON的详细语法，我最初认为是一个问题，实际上提供了一种很好的方法来扩展，同时保持向后兼容性。

Collection + JSON项链接到其他集合的项目
