问题描述
大家好，我正在使用WebHook作为后端，使用Dialogflow作为前端，我正在使用node js中的Dialogflow实施库，我知道如何利用丰富的响应消息，如使用Dialogflow前端的按钮，但如何从WebHook代码使用它，可能使用一些JSON？我想用建议筹码 目前，我知道如何使用这张卡见下面的代码，现在我想用建议芯片回应一下怎么做？//agent.add(new Card({
//title: `RDF Graph Visualization`,
//buttonText: 'open website',
//buttonUrl: 'https://xxherokuapp.com/visualize/' + graphId
//})
// )
推荐答案
我以WebHook的身份尝试了以下代码，并在Dialogflow Messenger上进行了测试。响应包含带有链接的建议筹码。
Index.js：
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const { Payload } = require("dialogflow-fulfillment");
process.env.DEBUG = 'dialogflow:debug';
exports.myfunction = 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(`Welcome to my agent!`);
}
function fallback(agent) {
agent.add(`I didn't understand`);
agent.add(`I'm sorry, can you try again?`);
}
function pet(agent){
agent.add(`which one u want`);
const payload = {
"richContent":[
[
{
"type":"chips",
"options":[
{
"text":"Dog",
"link" : "https://en.wikipedia.org/wiki/Dog"
},
{
"text":"Cat",
"link":"https://en.wikipedia.org/wiki/Cat"
},
{
"text":"Rabbit",
"link" : "https://en.wikipedia.org/wiki/Rabbit"
}
]
}
]
]
};
agent.add(new Payload(agent.UNSPECIFIED, payload, {rawPayload: true, sendAsMessage: true}));
}
let intentMap = new Map();
intentMap.set('Default Welcome Intent', welcome);
intentMap.set('Default Fallback Intent', fallback);
intentMap.set('mypet',pet);
agent.handleRequest(intentMap);
});
Package.json：
"name": "myfunction",
"description": "This is the webhook",
"version": "0.0.1",
"private": true,
"license": "Apache Version 2.0",
