Node.js 如何在Express中使用dialogflow实现节点
我想在Express中使用dialogflow实现库 这是我的代码:Node.js 如何在Express中使用dialogflow实现节点,node.js,express,dialogflow-es,Node.js,Express,Dialogflow Es,我想在Express中使用dialogflow实现库 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()
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');
};
这就是错误所在
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)
你能帮我吗?
如何将dialogflow fulfillment nodejs库与Express一起使用?WebhookClient构造函数使用带有字段
request
和response
的option对象。您将它们命名为req
和res
考虑到必须使用的参数doActions()
,构造函数行应该是这样的:
您需要使用主体解析器。看看这个例子:谢谢,伙计。这就是我要找的
const agent = new WebhookClient({
request: req,
response: res
});
