facebook-messenger-bot - Dialogflow V2 Messenger 与多条消息的集成

Question

我正在尝试在对 Dialogflow 的一个 Webhook 调用中发送多条消息，这些消息应传递给 Messenger。现在我的 Webhook 响应一个有问题的 JSON 正文:

{
    'fulfillmentText': "Text",
    'fulfillmentMessages': [{
        "platform": "facebook",
        "text": [{
            "text": "Text"
        }]
    }],
    'source': "facebook"
}

当我通过 Messenger 测试 Webhook 时，我看到了 is typing 符号，但从未收到 Text 消息。从 Dialogflow 控制台测试相同的 Webhook 时，我得到了

Webhook execution successful

回来了。我想我缺少一些 JSON 字段来告诉 Dialogflow 必须以哪种格式将 JSON 发送给 Messenger API。有人对如何解决这个问题有任何线索吗？

编辑:我最近的无效试用...

{
  "fulfillmentText": "Hola!",
  "fulfillmentMessages": [
    {
      "text": {
        "text": [
          "Title: this is a title"
        ]
      },
      "platform": "FACEBOOK"
    },
    {
      "text": {
        "text": [
          "Title: this is a title"
        ]
      },
      "platform": "FACEBOOK"
    }
  ]
}

Answer 1

如果您只发送文本，则只需向 fulfillmentText 提供一个字符串，而不必提供 fulfillmentMessages 属性。

如果您确实为目标平台提供了 fulfillmentMessages 属性，Dialogflow 会将您的负载发送到 Facebook。在这种情况下，如果有效负载无效，则实际上不会在 Facebook 中显示任何消息。删除响应 JSON 的 fulfillmentMessages 属性，您的机器人应该响应。

如果您想在回复中添加一张卡片，您可以发送以下回复:

{
  "fulfillmentMessages": [
    {
      "platform": "FACEBOOK",
      "card": {
        "title": "Title: this is a title",
        "subtitle": "This is an subtitle.  Text can include unicode characters including emoji 📱.",
        "imageUri": "https://developers.google.com/actions/images/badges/XPM_BADGING_GoogleAssistant_VER.png",
        "buttons": [
          {
            "text": "This is a button",
            "postback": "https://assistant.google.com/"
          }
        ]
      }
    }
  ]
}

编辑:如果您想发送多条消息，您可以通过发送这样的响应来实现(此 JSON 将发送两张相同的卡片，但您可以根据 this documentation 更改消息类型(卡片/文本/等)):

{
  "fulfillmentMessages": [
    {
      "platform": "FACEBOOK",
      "card": {
        "title": "Title: this is a title",
        "subtitle": "This is an subtitle.  Text can include unicode characters including emoji 📱.",
        "imageUri": "https://developers.google.com/actions/images/badges/XPM_BADGING_GoogleAssistant_VER.png",
        "buttons": [
          {
            "text": "This is a button",
            "postback": "https://assistant.google.com/"
          }
        ]
      }
    },
    {
      "platform": "FACEBOOK",
      "card": {
        "title": "Title: this is a title",
        "subtitle": "This is an subtitle.  Text can include unicode characters including emoji 📱.",
        "imageUri": "https://developers.google.com/actions/images/badges/XPM_BADGING_GoogleAssistant_VER.png",
        "buttons": [
          {
            "text": "This is a button",
            "postback": "https://assistant.google.com/"
          }
        ]
      }
    }
  ]
}
