我刚刚使用Dialogflow。我在nodejs中有一个webhook,当用户询问信息时,它会向用户发送响应,如果用户使用电报、脸书、电话线,我会发送不同的响应。。。到现在为止,我总是发送相同的邮件。这是我的webhook:

"use strict";

const express = require("express");
const bodyParser = require("body-parser");
const restService = express();

restService.use(
    bodyParser.urlencoded({
        extended: true
})
);

restService.use(bodyParser.json());

restService.post("/webhook", function(req, res) {
var speech =
req.body.result &&
req.body.result.parameters &&
req.body.result.parameters.tipo
  ? response(req.body.result.parameters.tipo.toLowerCase())
  : "Ups... ha habido algÃºn problema con nuestra comunicaciÃ³n, sorry!";
return res.json({
    speech: speech,
    displayText: speech,
    source: "webhook-echo-sample"
 });
});

let response = function(tipo){
   let response;
   switch(tipo){
       case 'daw':  response = 'http://moodle.iesgrancapitan.org/course/index.php?categoryid=7'; break;
       case 'asir':  response = 'http://moodle.iesgrancapitan.org/course/index.php?categoryid=4'; break;
       default: response = 'Vaya... Creo que algo fue mal'; break;
  }
  return response;
}

restService.listen(process.env.PORT || 8000, function() {
   console.log("Server up and listening");
});

有两种方法可以添加特定于平台的响应:

根据您的意愿,向下滚动至响应。在默认值旁边,有一个加号按钮,您可以选择要为哪个平台添加富消息。如果您随后进入“添加响应”,您可以从下拉菜单中选择您的丰富响应(madia、建议芯片等),然后在那里添加所需的所有信息。
通过添加自定义负载,从您的实现中。我已经附上了下面的片段,但要了解更多信息,您可以访问此链接 https://dialogflow.com/docs/fulfillment 。当然,不要忘记实现该目的:)
