如何在Dialogflow NodeJS客户端中设置自定义平台 [英] How to set a custom platform in Dialogflow NodeJS Client

问题描述

我已经使用 dialogflow-fulfillment 创建了一个Webhook，以正确地返回不同的数据，具体取决于在平台上，包括我为另一项服务创建的自定义项。我已经测试过Webhook，并且知道如果将 originalDetectIntentRequest.source 更改为自定义有效负载中使用的平台，它将可以正常工作。

I have created a webhook using dialogflow-fulfillment to correctly return different data depending on the platform, including a custom one I created for another service. I've tested my webhook and know that if I change the originalDetectIntentRequest.source to the platform used in my custom payload it works.

{
    "payload": {
        "jokes-api": {
            "success": true,
            "text": "These are some jokes",
        }
    },
    "outputContexts": []
}

我能够使用 dialogflow-nodejs-client-v2 的 sessions.detectIntent 可以获取响应，但是全功能返回平台设置为 PLATFORM_UNSPECIFIED ，而不是我想要的自定义有效负载。

I am able to use dialogflow-nodejs-client-v2's sessions.detectIntent to get a response, but the fullfilment comes back with the platform set as PLATFORM_UNSPECIFIED, and not the custom payloads I want.

[{
    "responseId": "c56c462f-bb3b-434a-b318-3739f58e6f6d",
    "queryResult": {
        "fulfillmentMessages": [{
            "platform": "PLATFORM_UNSPECIFIED",
            "card": {
                "buttons": [],
                "title": "Jokes",
                "subtitle": "These are some jokes",
                "imageUri": ""
            },
            "message": "card"
        }],
        "queryText": "tell me a joke",
        /* ... */
        "intent": {
            "name": "projects/my-jokes/agent/intents/56887375-3047-4993-8e14-53b20dd02697",
            "displayName": "Jokes",
            /* ... */
        },
        "intentDetectionConfidence": 0.8999999761581421,
    }
}]

查看我的Webhook日志，可以看到存在 originalDetectIntentRequest 对象，但没有源组。

Looking at the logs for my webhook, I can see that the originalDetectIntentRequest object is present, but source is not set.

{
  "responseId": "c56c462f-bb3b-434a-b318-3739f58e6f6d",
  "queryResult": {
    "queryText": "tell me a joke",
    "speechRecognitionConfidence": 0.9602501,
    /* ... */
    "intent": {
      "name": "projects/my-jokes/agent/intents/56887375-3047-4993-8e14-53b20dd02697",
      "displayName": "Jokes"
    },
    /* ... */
  },
  "originalDetectIntentRequest": {
    "payload": {
    }
  },
  "session": "projects/my-jokes/agent/sessions/12345"
}

我该如何

推荐答案

sessions.detectIntent API具有 queryParams 参数，该参数具有名为 payload 的字段。这就是原始有效载荷的来源。平台的名称进入该结构的 source 字段。因此，您的 detectIntent 调用应如下所示：

sessions.detectIntent API has queryParams parameter which has a field called payload. That's where the "original payload" goes. The name of the platform goes into the source field of that structure. So your detectIntent call should look something like this:

sessionClient.detectIntent({
    session: sessionClient.sessionPath('<project_id>', '<session_id>'),
    queryInput: {
        text: {
            text: '<query>',
            languageCode: 'en-US'
        }
    },
    queryParams: {
        payload: {
            fields: {
                source: {
                    stringValue: '<platform>',
                    kind: 'stringValue'
                }
            }
        }
    }
})

我能够通过使用'slack'作为平台名称来模拟Slack集成调用。我还能够为自定义平台名称返回自定义有效负载。有效负载在 queryResult.webhookPayload 字段中返回。

I was able to simulate Slack integration call by using 'slack' as a platform name. I was also able to return a custom payload for a custom platform name. The payload is returned in queryResult.webhookPayload field.
