一个竞价响应可包含多个 SeatBid 对象，每个代表一个不同的竞价方席位（bidder seat），各含一条或多条独立出价。若请求中呈现了多个展示，可用 group 属性指明该席位是愿意接受其能赢下的任何展示（默认），还是只有在能整组赢下时才感兴趣。译稿校对中ENA bid response can contain multiple SeatBid objects, each on behalf of a different bidder seat and each containing one or more individual bids. If multiple impressions are presented in the request, the group attribute can be used to specify if a seat is willing to accept any impressions that it can win (default) or if it is only interested in winning any if it can win them all as a group.
| Attribute | Type | Description |
|---|---|---|
| bid required | object[] | 1 个及以上 Bid 对象（参见第 4.2.3 节）的数组，每个 Bid 关联一个展示。多个 Bid 可以关联同一个展示。译稿校对中ENArray of 1+ Bid objects (Section 4.2.3) each related to an impression. Multiple bids can relate to the same impression. |
| seat | string | 本出价所代表的买方席位（buyer seat，如广告主、代理商）的 ID。译稿校对中ENID of the buyer seat (e.g., advertiser, agency) on whose behalf this bid is made. |
| group default 0 | integer | 0 = 各展示可逐一赢标；1 = 各展示必须作为整体同赢或同输。译稿校对中EN0 = impressions can be won individually; 1 = impressions must be won or lost as a group. |
| ext | object | 供竞价方（bidder）对 OpenRTB 进行专属扩展（bidder-specific extensions）的占位对象。译稿校对中ENPlaceholder for bidder-specific extensions to OpenRTB. |
译注
译者注SeatBid 的席位组织：一个响应可含多个 SeatBid，各代表一个买方席位；同一席位的多条出价可指向同一展示（创意轮换/价位试探），由交易平台裁决。译稿校对中
group 的整组语义：group = 1 即“全赢或全输”（all-or-nothing），适用于整页包段（road-blocking）等需要独占上下文的采买；交易平台需支持整组裁决，否则该标志无法兑现。译稿校对中
