在Dialogflow中为TELEGRAM添加自定义JSON负载，以使用户共享他们的电话号码

Question

下面的功能被认为是提供share_your_phone_number意图的实现。当调用意图时，将以电报的形式向用户显示共享您的电话号码键盘。

function share_your_phone_number(agent) {
agent.add(`Welcome.`);
agent.add(new Payload("telegram", {
    "text": "Please click on button below to share your number",
    "reply_markup": {
      "one_time_keyboard": true,
      "resize_keyboard": true,
      "keyboard": [
        [
          {
            "text": "Share my phone number",
            "callback_data": "phone",
            "request_contact": true
          }
        ],
        [
          {
            "text": "Cancel",
            "callback_data": "Cancel"
          }
        ]
      ]
    }
  }
 ));
} 

当我在内联编辑器中部署API时，在电报机器人聊天中只返回"Welcome“字符串。未显示键盘按钮。

我需要一个线索来解决这个问题。

Answer 1

在将Payload对象的构造函数创建为文档here时，platform和payload参数是必需的。

new Payload(platform, payload)

platform参数是WebhookClient对象的属性，假设webhookClient已实例化并存储在agent中，则应按此属性进行定义(agent.SLACK、agent.TELEGRAM等

示例：

agent.add(new Payload(agent.ACTIONS_ON_GOOGLE, {/*your Google payload here*/}); agent.add(new Payload(agent.SLACK, {/*your Slack payload here*/});

agent.add(new Payload(agent.TELEGRAM, {/*your telegram payload here*/});

参考：https://blog.dialogflow.com/post/fulfillment-library-beta/。

对于问题中概述的用例，这是我的完整解决方案：

    // See https://github.com/dialogflow/dialogflow-fulfillment-nodejs
    // for Dialogflow fulfillment library docs, samples, and to report issues
    'use strict';

    const functions = require('firebase-functions');
    const {WebhookClient} = require('dialogflow-fulfillment');
    const {Text, Card, Image, Suggestion, Payload} = require('dialogflow-fulfillment'); 
    process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements

    exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
    const agent = new WebhookClient({ request, response });
    console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
    console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

    function welcome(agent) {
      agent.add(new Payload(agent.TELEGRAM, {

        "text": "Please click on button below to share your number",
        "reply_markup": {
          "one_time_keyboard": true,
          "resize_keyboard": true,
          "keyboard": [
            [
              {
                "text": "Share my phone number",
                "callback_data": "phone",
                "request_contact": true
              }
            ],
            [
              {
                "text": "Cancel",
                "callback_data": "Cancel"
              }
            ]
          ]
        }
       }));
      }

      // Run the proper function handler based on the matched Dialogflow intent name
      let intentMap = new Map();
      intentMap.set('Default Welcome Intent', welcome);
      agent.handleRequest(intentMap);
    });

这是我的结果：

  function welcome(agent) {
    const payload = {
      "text": "Pick a color",
      "reply_markup": {
        "inline_keyboard": [
          [
            {
              "text": "Yellow",
              "callback_data": "Yellow"
            }
          ],
          [
            {
              "text": "Blue",
              "callback_data": "Blue"
            }
          ]
        ]
      }
    };

    console.log('queryText ' + JSON.stringify(agent.request_.body.queryResult.queryText));
    console.log('displayName ' + JSON.stringify(agent.request_.body.queryResult.intent.displayName)

    agent.add(
      new Payload(agent.TELEGRAM, payload, {rawPayload: false, sendAsMessage: true})
    );
  }

此外，您必须将package.json中的dialogflow-fulfillment版本更新为最新版本。现在我有了这个版本- "dialogflow-fulfillment": "^0.6.1"
