映射菜单 Feed 与履单购物车商品
当客户将菜单 Feed 中的商品添加到购物车并结账时，Google 会将这些商品发送到您的执行方式端点，以验证其价格和库存状况。验证价格和库存状况后，客户就可以下单了。本部分介绍了如何将菜单 Feed 项映射到履单购物车项。
本部分中的示例是菜单 Feed 和购物车架构的精简版本。系统仅会显示与菜单 Feed 和购物车对象之间的对应关系的相关字段。如需了解完整架构，请参阅 Menu 和 Cart。
Menu Feed 中添加到购物车的商品会通过 Cart 对象发送，以便结账和订单提交。
- 简单的
MenuItem在lineItems数组中表示为LineItem，其中offerId是所选菜单项在菜单 Feed 中的offer.id。 - 具有必需
MenuItemOption的MenuItem在lineItems数组中表示为LineItem，其中offerId是菜单 Feed 中所选菜单项选项的offer.id。 LineItem的AddOnMenuItem在FoodItemExtension的options数组中表示为FoodItemOption。每个选项都有一个offerId，对应于菜单 Feed 中所选插件菜单项的offer.id。请注意，AddOnMenuItem 还可以包含嵌套的 AddOnMenuItem，它们在每个选项内表示为subOptions。
以下示例在菜单 Feed 和履单购物车之间映射菜单项。

处理错误
如果您在处理 CheckoutRequestMessage 时遇到问题，可以使用包含 FoodErrorExtension 的 CheckoutResponseMessage 进行响应，而不是使用 CheckoutResponse。您可以使用此响应来识别处理期间发生的一个或多个错误。
您可以通过以下 2 种方式处理这些错误：
- 可恢复的错误：用户无需修改购物车即可提交订单。例如，如果您确定
Cart中的某件商品有价格变动，可以使用错误类型为PRICE_CHANGED的FoodOrderError以及correctedProposedOrder和paymentOptions进行响应。Google 会通知用户相应更改，但允许用户使用correctedProposedOrder提交。如果需要，用户还可以返回并修改购物车。您将收到一个新的CheckoutRequestMessage或SubmitOrderRequestMessage。 - 不可恢复的错误：用户必须先修改购物车，然后才能提交订单。例如，如果您确定餐馆已停业，可以做出响应，返回错误类型为
CLOSED的FoodOrderError。Google 通知用户并管理互动，以便更新到新餐馆。您将收到适用于新购物车的新CheckoutRequestMessage。
一般来说，应将购物车级错误和商品级错误设置为不可恢复。如需查看错误类型及其含义的完整列表，请参阅 FoodOrderError。
处理价格变动
结账时价格会发生变动
如果您在处理客户的 checkout 请求时遇到价格问题，请执行以下操作：
- 使用包含
FoodErrorExtension的CheckoutResponseMessage响应CheckoutRequestMessage，如处理错误中所述。 - 在错误响应中，使用
correctedProposedOrder.cart将价格更新为正确的值。Google 收到更正后的订单，并可能会发出新的CheckoutRequestMessage。
结账后，无论 ProposedOrder 是否发生更改，Google 都会向最终用户显示订单确认页面。
如果 ProposedOrder 已更正，Google 可能会显示其他警告，以通知用户相关更改。如果用户同意下单，将不再有结账请求。该流程会继续按已更正的 ProposedOrder 提交提交请求。
不过，用户随时可以改变主意，再次修改购物车。当他们的购物车以这种方式更新时，Google 会发送新的 CheckoutRequestMessage。
提交订单期间价格发生变动
如果您在处理订单提交（触发了 actions.intent.TRANSACTION_DECISION intent）时遇到价格问题，请不要返回错误，也不要在响应中更新价格。如果 SubmitOrderRequestMessage 中的价格、数量或其他详细信息与您的数据不对应，请在响应时将 orderState 设置为 REJECTED，以指明无法按照要求下单。
然后，如果订单和付款信息有效，请将 orderState 设置为 CREATED 或 CONFIRMED。此外，请添加 actionOrderId 以表示系统中的订单 ID。发送后续更新时必须使用此 ID。
如果您无法处理付款并且已经发送了 SubmitOrderRequestMessage，则可以发送 AsyncOrderUpdateRequestMessage 并将 orderState 设置为 REJECTED，让用户知道订单将无法完成。
提交订单后价格发生变动
如果您确定某个价格已不同于客户提交订单时使用的价格，则可以发出采用新价格的 AsyncOrderUpdateRequestMessage（如实现异步订单更新中所述）。
如需使用异步订单更新来更新价格，请执行以下操作：
- 请更改
lineItemUpdates[x].price的价格。此值反映的是商品的总成本（包括附加费）乘以数量。（如需了解详情，请参阅LineItem的price字段的说明。） - 在
lineItemUpdates[x].reason中输入说明。 - 将
lineItemUpdates[x].orderState设置为CONFIRMED。
您可以自行决定，在发送 AsyncOrderUpdateRequestMessage 之前或之后尝试通过付款方式扣款。如果交易失败（可能因为价格增量过高），请发送一条 AsyncOrderUpdateRequestMessage，在 OrderUpdate 中包含以下设置，告知 Google 失败情况：
- 将
orderState设为REJECTED。 - 在
label字段中描述失败情况。
结账验证
如第 4 步：实现结账中所述，您的执行方式端点应对每个传入的 CheckoutRequestMessage 执行验证，并使用 CheckoutResponseMessage 进行响应。
以下示例展示了成功验证的 CheckoutResponseMessage：
| 使用场景 | 如何实现 |
|---|---|
| 用例 1：验证成功 | 返回 CheckoutResponse。它必须具有 ProposedOrder 和 PaymentOptions。ProposedOrder 包含税费、费用和购物车总价。 |

提交订单验证
如第 7 步：实现提交订单中所述，您的执行方式端点应对每个传入的 SubmitOrderRequestMessage 执行验证，并使用 SubmitOrderResponseMessage 进行响应。
以下示例展示了成功验证的 SubmitOrderResponseMessage：
| 使用场景 | 如何实现 |
|---|---|
| 用例 1：成功创建订单 | 订单状态为 CREATED 的 SubmitOrderResponseMessage。它必须具有 actionOrderId、userVisibleId、orderManagementActions 和 estimatedFulfillmentTime。 |
| 情形 2：订单因付款问题被拒 | 订单状态为 REJECTED 的 SubmitOrderResponseMessage。它必须具有 actionOrderId、userVisibleId、orderManagementActions 和类型为 PAYMENT_DECLINED 的 rejectionInfo。 |
| 用例 3：用户的订单已被拒绝，且用户被标记为已禁 | 订单状态为 REJECTED 的 SubmitOrderResponseMessage。它必须具有 actionOrderId、userVisibleId、orderManagementActions 和类型为 INELIGIBLE 的 rejectionInfo。 |
| 用例 4：订单因用户信息不完整或无效而被拒 | 订单状态为 REJECTED 的 SubmitOrderResponseMessage。它必须具有 actionOrderId、userVisibleId、orderManagementActions 和类型为 INELIGIBLE 的 rejectionInfo。 |
| 情形 5：订单因未知原因而遭拒 | 订单状态为 REJECTED 的 SubmitOrderResponseMessage。它必须具有 actionOrderId、userVisibleId、orderManagementActions 和类型为 UNKNOWN 的 rejectionInfo。 |
