DialogFlow：通过Firebase（内联）云功能通过Fulfillment发布附件到Facebook

Question

我正在为我的Facebook页面设置一个Chatbot，Google Dialogflow处理对话。

对于特定的Intent，我需要发送2个响应。

1. 放入用户姓名的常规声明。
2. 带3个按钮的持久菜单

我理解，对于单个Intent，我无法通过Fulfillment代码发送第一个响应，并通过Dialogflow控制台UI发送第二个响应。因此，我需要编写代码来发送两个响应。

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，但不清楚不同页面的代码片段是如何适合它的。

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
    }

};

文本响应正在起作用，但Audio不是。我做得对吗？任何帮助赞赏。

更新1：更改mp3链接后，音频正在运行。但是文本响应不起作用。

在我的Cloud函数中发送到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，我期待

• displayText立即显示 - >哪个不起作用
• audio响应发生 - >现在正在改变mp3链接

我相信我需要通过data属性给出文本响应和音频响应。让我试试这里更新。

如果对给定的集成使用有效负载，则将忽略响应的文本。您需要将带有text属性的消息添加到facebook有效负载中，以便在Facebook Messenger中显示它。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 😃"
}
