如何在Express中使用dialogflow-fulfillment-nodejs [英] How use dialogflow-fulfillment-nodejs with Express

问题描述

我想在Express中使用对话框流程实现库

I want use dialogflow fulfillment library into Express

这是我的代码：

import * as express from 'express';
import * as bodyParser from 'body-parser';
import * as dialogflowController from './controllers/dialogflow';

const app: express.Application = express();
app.use(bodyParser.json());
app.post('/echo', dialogflowController.doActions);
const http = require('http');
const httpServer = http.createServer(app);
httpServer.listen(80, function () { // ascolta sulla porta 80 per comando: ngrok http 80
  console.log('HTTP Started!');
});



// dialogflowController controller unit

import { Request, Response, NextFunction } from 'express';
const { WebhookClient, Card, Suggestion } = require('dialogflow-fulfillment');


export let doActions = (req: Request, res: Response, next: NextFunction) => {
  console.log('here it works');
  const agent = new WebhookClient({ req, res });
  console.log('crashes to the previous line');
};

这是错误

Error: Request can NOT be empty.
[Node]     at new WebhookClient (D:\Progetti\node_modules\dialogflow-fulfillment\src\dialogflow-fulfillment.js:58:13)
[Node]     at exports.doActions (D:\Progetti\dist\controllers\dialogflow.js:14:19)
[Node]     at Layer.handle [as handle_request] (D:\Progetti\node_modules\express\lib\router\layer.js:95:5)

推荐答案

WebhookClient 构造函数采用一个选项对象，该对象具有字段 request 和 response 。您将它们命名为 req 和 res 。

The WebhookClient constructor takes an option object with fields request and response. You named them req and res.

构造函数给定您必须 doActions（）的参数，该行应类似于以下内容：

The constructor line should look something like this given the parameters you have to doActions():

const agent = new WebhookClient({
  request: req,
  response: res
});
