google-cloud-functions - 对话流 : Posting attchment to Facebook via Fullfillment via Firebase (inline) Cloud functions

Question

我正在为我的 Facebook 页面设置聊天机器人，并使用 Google Dialogflow 处理对话。

对于特定的 Intent，我需要发送 2 个响应。

1. 包含用户名的常规语句。
2. 具有 3 个按钮的固定菜单

我了解，对于单个 Intent，我无法通过 Fulfillment 代码发送第一个响应，也无法通过 Dialogflow 控制台 UI 发送第二个响应设置。因此，我需要编写代码来发送这两个响应。

我能够发送第一个响应。但无法发送 Rich 消息内容。 DialogFlow 文档显示了代码片段，但不清楚来自不同页面的代码片段如何适合它。

这是我的代码(只是发布 actionHandlers)试图发送一个语句和一个音频(https://dialogflow.com/docs/rich-messages#custom_payload)

const actionHandlers = {
    'input.welcome': () => {

        const speechText = 'Hi ' + userProfile['first_name'] + ', This is Eva, digital assistant of LMES Academy. Since my people are busy working on the content for the next video, I\'d like to help you with your needs 😃';
        const responsePayload = {
            'speech': speechText,
            'outputContexts': [{
                'user-name': userProfile.first_name 
            }],
            "data": {
                "facebook": {
                    "attachment": {
                        "type": "audio",
                        "payload": {
                            "url": "http://incompetech.com/music/royalty-free/mp3-royaltyfree/Funk%20Game%20Loop.mp3"
                        }
                    }
                }
            }
        };

        sendResponse(responsePayload);
    },

    // The default fallback intent has been matched, try to recover (https://dialogflow.com/docs/intents#fallback_intents)
    'input.unknown': () => {
        sendResponse('I\'m having trouble, can you try that again?'); // Send simple response to user
    }

};

文本响应有效，但 Audio 无效。我做的对吗？任何帮助表示赞赏。

更新 1: 在更改 mp3 链接后，音频可以正常工作。但是文本响应不起作用。

发送到我的云函数中的 response.json() 的对象的日志。

{
    "speech": "Hi Saiyasodharan, This is Eva, digital assistant of LMES Academy. Since my people are busy working on the content for the next video, I'd like to help you with your needs 😃",
    "displayText": "Hi Saiyasodharan, This is Eva, digital assistant of LMES Academy. Since my people are busy working on the content for the next video, I'd like to help you with your needs 😃",
    "data": {
        "facebook": {
            "attachment": {
                "type": "audio",
                "payload": {
                    "url": "http://66.90.93.122/ost/death-note-original-soundtrack/bowkqzxs/01%20Death%20note.mp3"
                }
            }
        }
    },
    "contextOut": [{
        "user-name": "Saiyasodharan"
    }]
}

在上面的代码中，我期望

• displayText 立即显示 -> 不起作用
• audio 响应发生 -> 更改 mp3 链接后，现在可以正常工作了

我相信我需要通过 data 属性提供文本响应和音频响应。让我在这里尝试更新。

如果您对给定集成使用负载，则响应文本将被忽略。您需要将具有属性 text 的消息添加到 facebook 有效负载，以便它显示在 Facebook Messenger 中。例如:

{
  "contextOut": [
    {
      "user-name": "Saiyasodharan"
    }
  ],
  "data": {
    "facebook": {
      "attachment": {
        "payload": {
          "url": "http://66.90.93.122/ost/death-note-original-soundtrack/bowkqzxs/01%20Death%20note.mp3"
        },
        "type": "audio"
      },
      "text": "Hi Saiyasodharan, This is Eva, digital assistant of LMES Academy. Since my people are busy working on the content for the next video, I'd like to help you with your needs 😃"
    }
  },
  "displayText": "Hi Saiyasodharan, This is Eva, digital assistant of LMES Academy. Since my people are busy working on the content for the next video, I'd like to help you with your needs 😃",
  "speech": "Hi Saiyasodharan, This is Eva, digital assistant of LMES Academy. Since my people are busy working on the content for the next video, I'd like to help you with your needs 😃"
}
