如何使用 dialogflow 创建个性化响应？

Question

我正在尝试使用 dialogflow 构建一个聊天机器人，它能够为用户提供书籍建议。但我真的找不到如何在 python 文件中构建响应。我的意思是，我希望如果意图是 "search-book"，那么它会根据用户所说的性别发送几本书。实际上，我的 python 文件在那里：

            text = parameters.get('text')
            Gender = parameters.get('Gender')

            print (
                'text: %s, Gender: %s' %
                (
                    text if text else "null",
                    Gender if Gender else "null",
                )
            )


if __name__ == '__main__':
  main()

对于 Google 本书 API 我找到了这个，它正在运行： https://github.com/hoffmann/googlebooks

我已经创建了一个名为 "gender" 的实体和一个名为 "search-book" 的意图

您需要做的是为您的意图实施 webhook（网络服务）。

在此处将 url 设置为您的 webhook

然后转到您的意图并为该意图启用 webhook

因此，当有人查询您的意图时，您的 webhook 将收到一个 post 带有 bellow josn body

的请求

{
  "responseId": "ea3d77e8-ae27-41a4-9e1d-174bd461b68c",
  "session": "projects/your-agents-project-id/agent/sessions/88d13aa8-2999-4f71-b233-39cbf3a824a0",
  "queryResult": {
    "queryText": "user's original query to your agent",
    "parameters": {
      "param": "param value"
    },
    "allRequiredParamsPresent": true,
    "fulfillmentText": "Text defined in Dialogflow's console for the intent that was matched",
    "fulfillmentMessages": [
      {
        "text": {
          "text": [
            "Text defined in Dialogflow's console for the intent that was matched"
          ]
        }
      }
    ],
    "outputContexts": [
      {
        "name": "projects/your-agents-project-id/agent/sessions/88d13aa8-2999-4f71-b233-39cbf3a824a0/contexts/generic",
        "lifespanCount": 5,
        "parameters": {
          "param": "param value"
        }
      }
    ],
    "intent": {
      "name": "projects/your-agents-project-id/agent/intents/29bcd7f8-f717-4261-a8fd-2d3e451b8af8",
      "displayName": "Matched Intent Name"
    },
    "intentDetectionConfidence": 1,
    "diagnosticInfo": {},
    "languageCode": "en"
  },
  "originalDetectIntentRequest": {}
}

你可以得到意图名称

body.queryResult.intent.displayName

也可以获取参数

body.queryResult.parameters

因为现在你有了你需要的参数，你可以调用你的 googlebooks api 并将结果发送回 google dialogflow

响应 json 应该是这样的

{
  "fulfillmentText": "This is a text response",
  "fulfillmentMessages": [
    {
      "card": {
        "title": "card title",
        "subtitle": "card text",
        "imageUri": "https://assistant.google.com/static/images/molecule/Molecule-Formation-stop.png",
        "buttons": [
          {
            "text": "button text",
            "postback": "https://assistant.google.com/"
          }
        ]
      }
    }
  ],
  "source": "example.com",
  "payload": {
    "google": {
      "expectUserResponse": true,
      "richResponse": {
        "items": [
          {
            "simpleResponse": {
              "textToSpeech": "this is a simple response"
            }
          }
        ]
      }
    },
    "facebook": {
      "text": "Hello, Facebook!"
    },
    "slack": {
      "text": "This is a text response for Slack."
    }
  },
  "outputContexts": [
    {
      "name": "projects/${PROJECT_ID}/agent/sessions/${SESSION_ID}/contexts/context name",
      "lifespanCount": 5,
      "parameters": {
        "param": "param value"
      }
    }
  ],
  "followupEventInput": {
    "name": "event name",
    "languageCode": "en-US",
    "parameters": {
      "param": "param value"
    }
  }
}

我用 node js 做了一些事情

 'use strict';
 const http = require('http');

 exports.bookWebhook = (req, res) => {

     if (req.body.queryResult.intent.displayName == "search-book") {
         res.json({
             'fulfillmentText': getbookDetails(req.body.queryResult.parameters.gender)
         });
     }
 };


 function getbookDetails(gender) {
     //do you api search for book here

     return "heard this book is gooooood";
 }

在 getbookDetails 函数中，您可以调用 api 获取书籍并格式化字符串和 return 字符串.. 同样应该应用于 python 和我们一样。只是语法会有所不同。
