Native§3.2.9 · Bid Request

该对象表示原生（native）类型的展示。原生广告单元旨在与周围内容无缝融合（如 Twitter 或 Facebook 上的赞助帖子），因此响应必须结构良好，以便发布方对渲染实施细粒度控制。Native 小组委员会（Native Subcommittee）制定了一份名为 Dynamic Native Ads API 的 OpenRTB 伴生规范，定义原生广告单元的请求参数与响应标记结构；本对象提供了将请求参数以不透明字符串传输的手段，使具体参数可在该规范的管辖下独立演进，下发的广告标记同样遵循其结构。Native 作为 Imp 的子对象出现，即表示该展示以原生类型提供；经发布方许可，同一展示还可通过在 Imp 下并列包含 Banner、Video 和/或 Audio 类型对象的方式同时以这些类型提供，但针对该展示的任一具体出价，只能符合所供类型中的一种。译稿校对中ENThis object represents a native type impression. Native ad units are intended to blend seamlessly into the surrounding content (e.g., a sponsored Twitter or Facebook post). As such, the response must be well-structured to afford the publisher fine-grained control over rendering. The Native Subcommittee has developed a companion specification to OpenRTB called the Dynamic Native Ads API. It defines the request parameters and response markup structure of native ad units. This object provides the means of transporting request parameters as an opaque string so that the specific parameters can evolve separately under the auspices of the Dynamic Native Ads API. Similarly, the ad markup served will be structured according to that specification. The presence of a Native as a subordinate of the Imp object indicates that this impression is offered as a native type impression. At the publisher’s discretion, that same impression may also be offered as Banner, Video, and/or Audio by also including as Imp subordinates objects of those types. However, any given bid for the impression must conform to one of the offered types.
