将websockets与Alexa技能包结合使用

Question

我有一个用node js编写的hello world alexa技能，并将其部署在heroku中。我必须使用websockets将响应发送到web ui(比如我本地机器中的html页面).Is这是可能的吗？

我的服务器代码-server.js

'use strict';

var AlexaAppServer = require( 'alexa-app-server' );

var server = new AlexaAppServer( {
 httpsEnabled: false,
 port: 8080
} );

server.start();

下面是index.js

 module.change_code = 1;
  'use strict';

var alexa = require( 'alexa-app' );
var app = new alexa.app('Helloworld');


 app.launch( function( request, response ) {
console.log(app);
//console.log(request);
response.say( 'Welcome to Welcome to helloworld.' );

});

app.error = function( exception, request, response ) {
 console.log(exception)
 console.log(request);
 console.log(response); 
 response.say( 'Sorry an error occured ' + error.message);
};

app.intent('Helloworld',
{
 "slots":[]
 ,"utterances":[ 
    "hello alexa",
    "hi alexa",
    "how are you?"]
},
function(request,response) {

  response.say("welcome user");
//send this same response to a webpage using socket

}
);


module.exports = app;

你是否正在尝试做html页面与alexa的互动。如果你是对的，你必须使用websocket，但你可以尝试AWS本身提供的API网关，在API网关中，你可以调用它到你的html页面，这个链接可能会对你有所帮助。https://blog.prototypr.io/using-voice-commands-to-control-a-website-with-amazon-echo-alexa-part-1-6-a35edbfef405
