Actions on google 如何在Dialogflow中创建包含丰富消息的响应？

当前，当调用一个intent时，我调用一个webhook并从web服务获得一个响应，如下面的json结构所示

{
  "speech": "this text is spoken out loud if the platform supports voice interactions",
  "displayText": "this text is displayed visually"
}

这仅仅是文本。或者，我必须得到什么样的响应才能显示列表（例如）

---

我尝试了dialogflow文档的富消息部分。这些结构不起作用。

要在谷歌列表中添加一个动作作为回复的一部分，您需要在回复中使用

数据
字段，包括一个
richsresponse
，以及一个包含列表信息的
systemIntent

您可以在其网站上看到更多示例，但下面是一个用于显示列表的示例：

{
  "data": {
    "google": {
      "expectUserResponse": true,
      "richResponse": {
        "items": [
          {
            "simpleResponse": {
              "textToSpeech": "Choose an item"
            }
          }
        ]
      },
      "systemIntent": {
        "intent": "actions.intent.OPTION",
        "data": {
          "@type": "type.googleapis.com/google.actions.v2.OptionValueSpec",
          "listSelect": {
            "title": "Hello",
            "items": [
              {
                "optionInfo": {
                  "key": "first title"
                },
                "description": "first description",
                "image": {
                  "url": "https://developers.google.com/actions/images/badges/XPM_BADGING_GoogleAssistant_VER.png",
                  "accessibilityText": "first alt"
                },
                "title": "first title"
              },
              {
                "optionInfo": {
                  "key": "second"
                },
                "description": "second description",
                "image": {
                  "url": "https://lh3.googleusercontent.com/Nu3a6F80WfixUqf_ec_vgXy_c0-0r4VLJRXjVFF_X_CIilEu8B9fT35qyTEj_PEsKw",
                  "accessibilityText": "second alt"
                },
                "title": "second title"
              }
            ]
          }
        }
      }
    }
  }
}

每次DialogFlow匹配一个意图时，您都可以要求DialogFlow向特定端点发送请求。显然，您需要编写一个端点

这将允许您检索匹配的意图，以及匹配的参数和上下文，并对它们进行一些有用的工作



使用webhook的富消息示例

}

{
"fulfillmentMessages": [{
    "payload": {
        "message": "Object1",
        "platform": "",  // Example - Facebook, Slack...etc

      {
        "name": "Save Promo",
        "action": {
          "type": "quickReply",
          "payload": {
            "message": "text will be sent as message",
            "replyMetadata": {
              "key1": "value1"
            }
          }
        }
      },
      {
        "name": "Save Coupon",
        "action": {
          "type": "quickReply",
          "payload": {
            "message": "text will be sent as message",
            "replyMetadata": {
              "key1": "value1"
            }
          }
        }
      }
}, {
    "payload": {
        "message": "Object2",
        "platform": ""   // Example - Facebook, Slack...etc
    }
}]
