Question

我想用Dialogflow和Google智能助理以及Google Transactions API创建一个聊天机器人，以便用户订购一些商品。现在我的代理包含以下四个意图：

Default Welcome Intent（文字回复：你好，你想买一个巧克力盒吗？）
Default Fallback Intent
Int3（培训短语：是的，我想要，履行：启用webhook）
Int4（事件：actions_intent_TRANSACTION_DECISION，履行：已启用webhook）

我使用Dialogflow Json而不是Node.js将我的代理与Transactions API连接起来。我想通过使用Google操作的actions.intent.TRANSACTION_DECISION操作最终使用用户满足交易要求，为用户构建购物车和订单。出于这个原因，在Google文档之后，当Int3被触发时，我正在使用webhook连接Google Assistant我的后端，后端发回以下json以触发actions.intent.TRANSACTION_DECISION。

因此，订单的预览会在Google智能助理（手机）上显示给用户。但是，此订单预览中未显示送货地址详细信息，如下图所示。

请注意，我已经前往Google Assistant app - ＆gt; Settings - ＆gt; Payments我填写了我的地址详细信息。因此，当我按预期触发actions.intent.DELIVERY_ADDRESS意图时，我会收到Google Assistant app - ＆gt;的送达地址。 Settings - ＆gt; Payments，如下图所示：Image。因此，我并没有预料到我的送货地址会出现在订单预览中，而不是首先设置它。

我的印象是，可以通过将extension object添加到ProposedOrder object的整个结构中来完成此操作，如下所示：

{   "id": string,   
"cart": {
        object(Cart)   },  
 "otherItems": [
        {
          object(LineItem)
        }   ],   "image": {
        object(Image)   },   
"termsOfServiceUrl": string,   
"totalPrice": {
        object(Price)   },   
"extension": {
        "@type": string,
        field1: ...,
        ...   } }

因此，通过我的webhook触发actions.intent.TRANSACTION_DECISION的整个json响应如下：

{
    "fulfillmentText": "This is your order preview:",
    "payload": {
        "google": {
            "expectUserResponse": true,

                "intent": "actions.intent.TRANSACTION_DECISION"
            }
        }
    }
}

但是我在Google智能助理模拟器上收到此错误：

Sorry, something went wrong. Please try again later.

所以我无法理解我是否在extension object的类型和格式方面做得不对。

在这种情况下，Google智能助理的日志如下：

如何将送货地址详细信息添加到订单预览中？

这是Google文档订单预览的示例，其中包含送货地址详细信息：

P.S。 object(Cart)包含"notes": string，可以在最终订单预览中添加一个部分，确切地将交货地址部分放置在上面照片的订单预览处。因此，我可以添加

"notes": "Lola\n1950 Charleston Road\nMountain View, CA 94043\n415 789 8934"

或我的个人地址详细信息到object(Cart)然后我可以将交付详细信息显示在最终订单预览中，如下图所示：Image。 < / p>

然而，通过这种方式，订单预览中此部分的标题为Notes，而我显然希望Delivery address作为上面照片中显示的标题。

Answer 1

根据您获得的错误，@type的URI值看起来不正确。

由于您已经构建了ProposedObject，因此您需要在@type: type.googleapis.com/google.actions.v2.orders.GenericExtension的{{1}}字段内使用extension（注意订单< / strong>在URI中）。根据您提到的docs，ProposedObject将有一个GenericExtension数组，其中包含locations类型的对象，您可以在其中指定传递地址。

扩展程序的最终JSON将如下所示：

OrderLocation

其他"extension": { "@type": "type.googleapis.com/google.actions.v2.orders.GenericExtension", "locations": [ { type: 'DELIVERY', location: { "postalAddress": { "regionCode": "USA", "recipients": [ "Me" ], }, "phoneNumber": "123456789" } } ] }字段与示例中的字段相同。

有关详细信息，请参阅official sample中使用Transactions API的示例。
