根据收到的错误， @type 的URI值似乎是不正确
由于您已经在构建 ProposedObject ，因此您需要使用 @在（请注意URI中的订单）。根据您提到的文档，的 ProposedObject 扩展名字段内输入type.googleapis.com/google.actions.v2.orders.GenericExtension GenericExtension 将具有一个位置数组，其中将包含一个 OrderLocation 类型的对象指定送货地址。
扩展的最终JSON如下：
扩展名：{
@type： type.googleapis.com/google.actions.v2.orders.GenericExtension，
位置：[
{
类型：交付，
位置：{
postalAddress：{
regionCode： USA，
收件人：[
我
]，
}，
phoneNumber： 123456789
}
}
]
}
ProposedOrder 其余字段与你的例子
请在官方示例以获取更多详细信息。
I want to create a chatbot with Dialogflow and Google Assistant along with Google Transactions API for enabling a user to order some items. For now my agent contains the following four intents:
Default Welcome Intent (text response: Hello, do you want to buy a chocolate box?)Default Fallback IntentInt3 (training phrase: Yes, I want, fulfilment: enabled webhook)Int4 (event: actions_intent_TRANSACTION_DECISION, fulfilment: enabled webhook)I am using Dialogflow Json instead of Node.js to connect my agent with Transactions API. I want to build a cart and an order for the user by using finally that the user meets the transaction requirements by using the actions.intent.TRANSACTION_DECISION action of Google actions. For this reason, following Google docs, when Int3 is triggered I am using a webhook which connect Google Assistant my back-end which sends back the following json to trigger actions.intent.TRANSACTION_DECISION.
As a result, the preview of the order is presented to the user on Google Assistant (on mobile phone). However, the delivery address details are not presented on this order preview as at the photo below.
Let me note that I have already gone to Google Assistant app -> Settings -> Payments and there I filled in my address details. As a result, when I trigger the actions.intent.DELIVERY_ADDRESS intent then as expected I get the delivery address of Google Assistant app -> Settings -> Payments as this is shown at this image: Image. Therefore, it is not that I anticipated that my delivery address will appear on the order preview out of nowhere without having set it first of all.
I have the impression that this can be done by adding the extension object to the whole structure of ProposedOrder object which is the following:
{ "id": string,
"cart": {
object(Cart) },
"otherItems": [
{
object(LineItem)
} ], "image": {
object(Image) },
"termsOfServiceUrl": string,
"totalPrice": {
object(Price) },
"extension": {
"@type": string,
field1: ...,
... } }
So the whole json response through my webhook to trigger actions.intent.TRANSACTION_DECISION is the following:
{
"fulfillmentText": "This is your order preview:",
"payload": {
"google": {
"expectUserResponse": true,
"isSsml": false,
"noInputPrompts": [],
"systemIntent": {
"data": {
"@type": "type.googleapis.com/google.actions.v2.TransactionDecisionValueSpec",
"orderOptions": {
"requestDeliveryAddress": true
},
"paymentOptions": {
"actionProvidedOptions": {
"displayName": "VISA **** **** **** 3235",
"paymentType": "PAYMENT_CARD"
}
},
"proposedOrder": {
"cart": {
"lineItems": [
{
"description": "Book",
"id": "1",
"name": "Book",
"price": {
"amount": {
"currencyCode": "USD",
"nanos": 0,
"units": 31
},
"type": "ACTUAL"
},
"quantity": 2,
"subLines": [],
"type": "REGULAR"
}
],
"merchant": {
"id": "Amazon",
"name": "Amazon"
},
"otherItems": []
},
"extension": {
"@type": "type.googleapis.com/google.actions.v2.orders.GenericExtension",
"locations": [
{
"location": {
"phoneNumber": "123456789",
"postalAddress": {
"recipients": [
"Me"
],
"regionCode": "USA"
}
},
"type": "DELIVERY"
}
]
},
"id": "<UNIQUE_ORDER_ID>",
"otherItems": [],
"totalPrice": {
"amount": {
"currencyCode": "USD",
"units": 31
},
"type": "ACTUAL"
}
}
},
"intent": "actions.intent.TRANSACTION_DECISION"
}
}
}
}
but then I am getting this error on the Google Assistant simulator:
Sorry, something went wrong. Please try again later.
So I cannot really understand if I am not doing something right regarding the type and the format of the extension object.
The logs at Google Assistant in this case are the following:

How to add the delivery address details to the order preview?
This is an example of an order preview from Google docs which includes delivery address details:
P.S. The object(Cart) contains the "notes": string which can add a section at the final order preview exactly where the Delivery address section is placed at the order preview at the photo above. Therefore, I can add
"notes": "Lola\n1950 Charleston Road\nMountain View, CA 94043\n415 789 8934"
or my personal address details to the object(Cart) and then I can display the delivery details to the final order preview as it is shown at this image: Image.
However in this way the title of this section at the order preview is Notes while I want obviously Delivery address as the title as it it shown at the photo above.
Based on the error you're getting, it looks like the URI value for @type is incorrect.
Since you're already building a ProposedObject, you will need to use a @type: type.googleapis.com/google.actions.v2.orders.GenericExtension inside of the extension field of the ProposedObject (note orders in the URI). Per the docs you mentioned, GenericExtension will have a locations array that will contain an object of type OrderLocation where you can specify the delivery address.
The final JSON for an extension will look like:
"extension": {
"@type": "type.googleapis.com/google.actions.v2.orders.GenericExtension",
"locations": [
{
type: 'DELIVERY',
location: {
"postalAddress": {
"regionCode": "USA",
"recipients": [
"Me"
],
},
"phoneNumber": "123456789"
}
}
]
}
The rest of ProposedOrder fields will be the same as in your example.
Please see an example of using Transactions API in the official sample for more details.
