您可以在执行方式中添加支持，以便用户提前安排自提和送餐。在执行方式中实现此支持之前，请先创建一个服务目录 Feed，以指定用户提前下单的时间，如商品目录 Feed 架构 (AdvanceServiceDeliveryHoursSpecification) 中所述。
提前订购时段
Google 建议根据餐厅或服务的履单时间（如 AdvanceServiceDeliveryHoursSpecification 中所定义），以 15 分钟为增量提前最多 7 天提前订餐。
如需检索建议的提前下单空档，请在结账时使用 FoodCartExtension 对象的 fulfillmentPreference 字段中的值：
PickupInfo.pickupTimeIso8601DeliveryInfo.deliveryTimeIso8601
在结账时采用提前下单
下表列出了用户尝试下单时，在结账时实现执行方式响应的可能方式。
| 场景 | 执行方式 |
|---|---|
| 可以为所请求的空档履行提前订单。 | 通过使用相同的槽位创建 ProposedOrder，接受 P0M（“尽快”）或 FUTURE_SLOT 购物车。如需查看接受空档的结账响应的示例，请参阅此代码段。 |
| 无法针对所请求的空档完成提前订单。 | 您的执行方式应执行以下操作：
如需查看有关建议替代空档的结账响应的示例，请参阅此代码段。 |
履单的其他空档
在结账时，如果 Google 建议的提前下单槽不合适，您的履单服务可以使用 CheckoutResponseMessage 对象建议替代品。
如需指定其他提前订购时段，请使用 FoodErrorExtension 响应结账请求，并设置以下值：
- 在
foodOrderErrors参数中，指定错误类型（例如UNAVAILABLE_SLOT、NO_CAPACITY或CLOSED）。 - 在
correctedProposedOrder参数中，通过availableFulfillmentOptions提供备用P0M或FUTURE_SLOT值。
替代空档应是下单后 7 天内的空档，包括可履行用户请求的购物车的所有空档。
例如，假设特价午餐仅在周一至周五上午 11 点到下午 1 点提供。然后，用户尝试将特惠午餐添加到购物车，但所选时段不可用。在这种情况下，您的履单服务应在购物车中保留特价午餐，并且在接下来的 7 天内仅返回上午 11 点到下午 1 点的空档
您应该在响应中省略 correctedProposedOrder.Cart.fulfillmentPreference 对象。
如果没有可用的空档，或者餐厅或服务不支持提前订餐，则无需提供 correctedProposedOrder。
请参阅下面的示例，了解在餐馆或服务可以接受预订的结账请求和提前订单响应流程中履单与 Google 之间的 JSON 消息。
示例：包含送货时段的 CheckoutRequest
以下代码段展示了包含提前下单配送时段的结账请求示例。

在提交订单时实施提前下单
在提交订单时，如果提前订单空档存在问题，则您的 SubmitOrderResponseMessage 应在 RejectionInfo 对象中包含原因（例如 UNAVAILABLE_SLOT 或 UNKNOWN）。
当提供商接受订单后，在 OrderState 对象中将订单状态从 CREATED 更新为 CONFIRMED。在发送给用户的确认电子邮件中包含所选时间段。
如果您的履单稍后会将订单发送给餐馆，请使用异步订单更新操作向 Google 发送更新。
在执行方式的提交订单响应或后续异步订单更新的 OrderUpdate 对象中，添加一个 estimatedFulfillmentTimeIso8601，其值设置如下：
- 当订单状态为
CREATED或CONFIRMED时，请将值设置为用户为其提前订购的送货或自提时间。 - 如果餐厅或服务能够提供更准确的预计送货时间，请将该值设置为预计送货或自提时间。

- 用户可以在 12 月 25 日下单并选择当天送达。
- 用户可以在 12 月 25 日提前下单，并安排在 12 月 27 日送达。
- 用户不能在 12 月 22 日提前下单，即安排在 12 月 25 日送达。
