Asset Response§5.2 · Bid Response
对应请求中的 `Asset Request` 对象。交易平台（exchange）代表渲染客户端所请求或支持的每个资产的主容器对象。必需的对象须显式标记。每个对象中 {title,img,video,data} 只应存在其一，其余应为 null/absent。id 在资产数组内须唯一，以便响应可以对齐。译稿校对中ENCorresponds to the Asset Object in the request. The main container object for each asset requested or supported by Exchange on behalf of the rendering client. Any object that is required is to be flagged as such. Only one of the {title,img,video,data} objects should be present in each object. All others should be null/absent. The id is to be unique within the AssetObject array so that the response can be aligned.
| 属性 | 类型 | 必填性 | 默认值 | 描述 |
|---|---|---|---|---|
| id | integer | 必填 | — | 唯一资产 ID，由交易平台分配，必须匹配请求中的某个资产 ID。译稿校对中ENUnique asset ID, assigned by exchange, must match one of the asset IDs in request. |
| required | integer | 可选 | 0 | 若该资产为必需（出价方要求其被展示）则置 1。译稿校对中ENSet to 1 if asset is required. (bidder requires it to be displayed). |
| title | object | 可选 | — | 标题资产的 `Title Response` 对象；见 TitleObject 定义。译稿校对中ENTitle object for title assets. See TitleObject definition. |
| img | object | 可选 | — | 图像资产的 `Image Response` 对象；见 ImageObject 定义。译稿校对中ENImage object for image assets. See ImageObject definition. |
| video | object | 可选 | — | 视频资产的 `Video Response` 对象；见 Video 响应对象定义。注意插播类视频广告不属于 Native；Native 广告可以将视频作为广告创意本身包含。译稿校对中ENVideo object for video assets. See Video response object definition. Note that in-stream video ads are not part of Native. Native ads may contain a video as the ad creative itself. |
| data | object | 可选 | — | 评分、价格等的 `Data Response` 对象。译稿校对中ENData object for ratings, prices etc. |
| link | object | 可选 | — | 行动号召（call to action）的 link 对象。当该资产条目被激活（点击）时适用；若资产上没有 link 对象，则适用竞价响应上的父级 link 对象。译稿校对中ENLink object for call to actions. The link object applies if the asset item is activated (clicked). If there is no link object on the asset, the parent link object on the bid response applies. |
| ext | object | 可选 | — | 占位对象，可包含双方约定的自定义 JSON，以支持超出本规范所定标准的灵活性。译稿校对中ENThis object is a placeholder that may contain custom JSON agreed to by the parties to support flexibility beyond the standard defined in this specification |
