Asset Request§4.2 · Bid Request
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（官方原文如此），其余应为 null/absent。id 在 `Asset Request` 数组内须唯一，以便响应可以对齐。译稿校对中ENThe 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，通常为数组下标计数。译稿校对中ENUnique asset ID, assigned by exchange. Typically a counter for the array. |
| required | integer | 可选 | 0 | 若该资产为必需（缺少它交易平台将不接受出价）则置 1。译稿校对中ENSet to 1 if asset is required (exchange will not accept a bid without it) |
| title | object | 可选 | — | 标题资产的 `Title Request` 对象；见 Title 对象定义。译稿校对中ENTitle object for title assets. See Title Object definition. |
| img | object | 可选 | — | 图像资产的 `Image Request` 对象；见 Image 对象定义。译稿校对中ENImage object for image assets. See Image Object definition. |
| video | object | 可选 | — | 视频资产的 `Video Request` 对象；见 Video 对象定义。注意插播类（in-stream）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 the Video 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 Request` 对象；见 Data 对象定义。译稿校对中ENData object for ratings, prices etc. See Data Object definition. |
| 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 |
注记
对象描述中 '{title,,img,video,data}' 的双逗号为官方原文（忠实保留）。
