Question

我目前正在研究使用Dialogflow构建聊天机器人的解决方案。在创建原型的过程中，我决定将我的GitHub存储库托管在heroku上。

但是，在这种情况下，如果我想使用 dialogflow-fillfillment库并在Nodejs中表达 ，它将无法正常工作。

请参见下面的代码

'use strict';
const { WebhookClient, Card, Suggestion } = require('dialogflow-fulfillment');   
const express = require('express');  
const app = express();
app.use( express.json() );
app.get('/', (req, res) => processWebhook( req, res ));
app.listen(process.env.PORT || 3000, () => console.log('App listening on port 3000!'));
var processWebhook = function( 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));
  response.send('Hello World');
};

这是package.json文件

 {
  "name": "FAQbot",
  "description": "",
  "version": "0.0.1",
  "private": true,
  "license": "",
  "author": "",
  "engines": {
    "node": ">=6.0"
  },
  "scripts": {
    "start": "node index.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "dependencies": {
    "express": "^4.16.3",
    "dialogflow": "^0.5.0",
    "dialogflow-fulfillment": "^0.5.0"
  }
}

这就是heroku日志的样子：

dialogflow-fillfillment库仅在Firebase环境上工作吗？

如何在heroku中为项目使用dialogflow实现库并使用nodejs进行表达？
