Question

我在我的raspberry pi上运行一个Node.js mqtt订阅服务器，通过我的lambda aws代码监听已发布的事件。发布事件是通过Alexa Skill事件触发的。

实施例

＆＃34; Alexa，告诉电视转到第10频道＆＃34; - 然后我的Lambda代码将此意图识别为ChannelNumberIntent意图，然后将带有频道号的正确消息发布到我的Raspi上的mqtt服务器。然后Raspi执行更改通道逻辑。

我已经使用alexa-app-server在本地运行这个并且它完全正常。 Alexa的响应工作，mqtt服务器收到正确的数字/消息包。

当我在测试选项卡上使用开发人员技能门户中的Alexa技能进行测试时，会出现问题。它运行正常，从收到的lambda说消息返回响应，但mqtt用户从未收到通道数字/消息包？我相信在困扰我的lambda代码几个小时之后的某个地方搞砸了。这是我的代码;

LAMBDA AWS CODE

    'use strict';
module.change_code = 1;
var Alexa = require('alexa-app');
var skill = new Alexa.app('tvRemote');
var awsIot = require('aws-iot-device-sdk');
var deviceName = "tvRemote";
var _ = require('lodash');
var path = require('path');

var host = "randomletters.iot.us-east-1.amazonaws.com";

//App id is the skill being used.
var app_id = "amzn1.ask.skill.more random letters";

var thingShadows = awsIot.thingShadow({

    keyPath: path.join(__dirname, '/Raspi.private.key'),
    certPath: path.join(__dirname, '/Raspi.cert.pem'),
    caPath: path.join(__dirname, '/root-CA.crt'),
    clientId: deviceName,
    region: "us-east-1",
});

var reprompt = 'I didn\'t hear a channel, tell me a channel number or name to change to that channel';

skill.launch(function (request, response) {
    var prompt = 'To change channel, tell me a channel number.';
    response.say(prompt).reprompt(reprompt).shouldEndSession(true);
});

skill.intent('ChannelNumberIntent', {
        'slots': {
            'CHANNELNUMBER': 'CHANNELID'
        },
        'utterances': ['{|Change|put} {|the|on} {|channel} {|to} {-|CHANNELNUMBER}']
    },
    function (request, response) {
        var channelNumber = request.slot('CHANNELNUMBER');

        if (_.isEmpty(channelNumber)) {
            var prompt = 'I didn\'t hear a channel code. Tell me a channel code.';
            response.say(prompt).shouldEndSession(true);
            return true;
        } else {

            thingShadows.publish('lambda/channelNumber', channelNumber, function () {
                var prompt1 = 'Okay.';
                response.say(prompt1).shouldEndSession(false);
                return true;
            });


            return true;

        }


    }
);

module.exports = skill;

MQTT服务器

   'use strict'

var mqtt = require('mqtt')
var fs = require('fs')
var path = require('path')
var KEY = fs.readFileSync(path.join(__dirname, '/Raspi.private.key'))
var CERT = fs.readFileSync(path.join(__dirname, '/Raspi.cert.pem'))
var TRUSTED_CA_LIST = fs.readFileSync(path.join(__dirname, '/root-CA.crt'))

var PORT = Corretportnumber
var HOST = 'RASPIHOSTWORDSASDFSDF.iot.us-east-1.amazonaws.com'

var options = {
    port: PORT,
    host: HOST,
    key: KEY,
    cert: CERT,
    rejectUnauthorized: true,
    // The CA list will be used to determine if server is authorized
    ca: TRUSTED_CA_LIST
}

var client = mqtt.connect('mqtts://' + HOST, options)

client.subscribe('lambda/channelNumber')

client.on('connect', function () {
    console.log('Connected')
})

client.on('message', function (topic, message) {
    if (topic === 'lambda/channelNumber') {

      //  logic.changeChannelCode(message);

        console.log(message.toString());


    }
})

显然隐藏了主机和端口号

Alexa Skill在本地工作，但在技能开发人员门户中进行测试时则不行
