如何在Dialogflow v2 WebhookResponse中发送FulfillmentMessages？ [英] How to send FulfillmentMessages as part of Dialogflow v2 WebhookResponse?

问题描述

我正在尝试将实现消息作为Dialogflow v2 API WebhookResponse的一部分发送回去。

I'm trying to send back fulfillment messages as part of Dialogflow's v2 API WebhookResponse.

这可行：

仅发送 FulfillmentText 作为我的响应的一部分就可以正常工作（在 Google模拟器上的操作中测试应用，并以正确的 FulfillmentText value）：

Sending only a FulfillmentText as part of my response works fine (Testing the app in the Actions on Google Simulator replies with the proper FulfillmentText value) :

func random(c *gin.Context, wr dialogflow.WebhookRequest)  {
    log.Println("Random action detected")

    fullfillment := dialogflow.WebhookResponse{
        FulfillmentText: "foobar",
    }

    c.JSON(http.StatusOK, fullfillment)
}

返回的JSON：

{"fulfillment_text":"foobar"}

模拟器中的响应：

{
    "conversationToken": "[]",
    "finalResponse": {
    "richResponse": {
        "items": [
            {
                "simpleResponse": {
                    "textToSpeech": "foobar"
                }
            }
        ]
    }
},
    "responseMetadata": {
    "status": {
        "message": "Success (200)"
    },
    "queryMatchInfo": {
        "queryMatched": true,
            "intent": "24db2044-f2fb-4607-9897-1de757990622"
    }
}
}

这不是：

但是我尝试发回任何实际消息（文本消息，基本卡，简单响应等）作为 FulfillmentMessages 的一部分，则测试失败：

But as soon as I try to send back any actual messages (Text Message, Basic Card, Simple Response, etc.) as part of FulfillmentMessages, the test fails:

func random(c *gin.Context, wr dialogflow.WebhookRequest)  {
    log.Println("Random action detected")

    textMessage := dialogflow.Intent_Message_Text{
        Text: []string{"foo", "bar"},
    }

    fullfillment := dialogflow.WebhookResponse{
        FulfillmentText: "foobar",
        FulfillmentMessages: []*dialogflow.Intent_Message{
            {
                Message: &dialogflow.Intent_Message_Text_{
                    Text: &textMessage,
                },
            },
        },
    }

    c.JSON(http.StatusOK, fullfillment)
}

正在发送回JSON：

{
    "fulfillment_text":"foobar",
    "fulfillment_messages":[
        {
            "Message":{
                "Text":{
                    "text":[
                        "foo",
                        "bar"
                    ]
                }
            }
        }
    ]
}

模拟器中的响应：

{
    "responseMetadata": {
    "status": {
        "code": 10,
            "message": "Failed to parse Dialogflow response into AppResponse because of empty speech response",
            "details": [
            {
                "@type": "type.googleapis.com/google.protobuf.Value",
                "value": "{\"id\":\"917d8ac3-3f0f-4953-b556-4dec27b8bbb8\",\"timestamp\":\"2018-10-22T09:00:45.488Z\",\"lang\":\"en-us\",\"result\":{},\"alternateResult\":{},\"status\":{\"code\":206,\"errorType\":\"partial_content\",\"errorDetails\":\"Webhook call failed. Error: Failed to parse webhook JSON response: Cannot find field: Message in message google.cloud.dialogflow.v2.Intent.Message.\"},\"sessionId\":\"ABwppHHSbrqOCPRp_DAPDLepL6YjSNpbzQ61CIBDTMl99rtRqfaWq-y0HtExb1--k6bcaL4CACQMeiVF3p-x5qk\"}"
            }
        ]
    }
}
}

我假设我的Web服务发送回的JSON错误，因为它返回 ...找不到字段：Message ... 作为其响应的一部分。
我正在为Dialogflow使用正确的Golang SDK（ https://godoc.org/google.golang.org/genproto/googleapis/cloud/dialogflow/v2#WebhookResponse ）

I am assuming that the JSON that my web service sends back is wrong, since it returns ... Cannot find field: Message ... as part of its response. I am using the proper Golang SDK for Dialogflow though (https://godoc.org/google.golang.org/genproto/googleapis/cloud/dialogflow/v2#WebhookResponse)

这是在Google模拟器上的Actions上进行了测试，以及在Pixel 2上运行了实际的Google Assistant。

This was tested on Actions on Google's Simulator as well as running the actual Google Assistant on a Pixel 2.

有人能指出我正确的方向吗？

Can anybody point me in the right direction what I am doing wrong?

推荐答案

正如您所说，问题出在响应的json结构上。以下是有效的webhook响应

As you said, the issue is with the json structure of the response. Below is a working webhook response

{
"fulfillmentMessages": [
    {
        "text": {
            "text": [
                "foo",
                "bar"
            ]
        }
    }
],
"fulfillmentText": "foobar",
"source": "Test"
}

1. 消息在实际结构中不存在。


2. fullfillment_text 应该是 fulfillmentText


3. 外部 Text 应该是 text


4. fullfillment_messages 应该是 fulfillmentMessages

1. Messages is not present in the actual structure.
2. fullfillment_text should be fulfillmentText
3. Outer Text should be text
4. fullfillment_messages should be fulfillmentMessages
