Question

我正在为Amazon Alexa建立一项技能，该技能可以从网站检索播客并播放。播客正在正常播放并停止播放，但是尝试停止并恢复播放时出现问题。

首先，亚马逊说我可以说“ Alexa，暂停”或“ Alexa，恢复”来暂停和恢复音频。但是在我的代码中，这会导致技能响应出错，因此我必须使用调用名称才能使它们起作用。

我的第二个问题是，当我暂停音频流时，它停止了。但是当我恢复它时，它从LaunchRequest开始。它不只是从头开始流式传输。看起来Alexa认为调用“ open mySkill”和“ resume mySkill”是同一件事。但是“恢复”应该是从流媒体暂停之前开始的声音。

我尝试更改参数“ shouldEndSession”，但这不是我想要的，因为它使Alexa等待新的响应，而不是流音频。

这是我的代码的一部分。

SimplePlayer.prototype.handle = function () {
var requestType = this.event.request.type;
var userId = this.event.context ? this.event.context.System.user.userId : this.event.session.user.userId;
var epId = this.id_episode;
//variabile per gestire i diversi linguaggi della richiesta
var requestLang = this.event.request.locale;


// On launch, we tell the user what they can do (Play audio :-))
if (requestType === "LaunchRequest") {
    if(requestLang === "en-US")
        this.say("Welcome to the commonsense radio. Say Start to play some audio!", "You can say Start");
    else if(requestLang === "it-IT")
        this.say("Benvenuto nella Radio del Buonsenso. Puoi dire avvia per ascoltare l'ultimo programma!", "You can say Play");
// Handle Intents here - Play, Pause and Resume is all for now
} else if (requestType === "IntentRequest") {
    var intent = this.event.request.intent;
    if (intent.name === "AvviaRadioIntent") {
        this.play(podcastURL + epId + "/play", 0);

    } else if (intent.name === "AMAZON.StopIntent") {
        // When we receive a Pause Intent, we need to issue a stop directive
        //  Otherwise, it will resume playing - essentially, we are confirming the user's action
        //this.say("stop", "stop");
        if(requestLang === "it-IT")
            this.stop("Sto terminando la riproduzione come richiesto", "Termino la riproduzione");
        else if(requestLang === "en-US")
            this.stop("I'm closing the audio stream as requested. ", "Closing the audio stream.");
    } else if (intent.name === "AMAZON.PauseIntent") {
            this.stop("","");
            this.attributes.offsetInMills = this.event.request.offsetInMilliseconds;
    } else if (intent.name === "AMAZON.ResumeIntent") {
            this.play(podcastURL + epId + "/play", this.attributes.offsetInMills);
    } else if (intent.name === "AMAZON.StartOverIntent") {
        var lastPlayed = this.loadLastPlayed(userId);
        var offsetInMilliseconds = 0;
        if (lastPlayed !== null) {
            offsetInMilliseconds = lastPlayed.request.offsetInMilliseconds;
        }

        this.play(podcastURL, offsetInMilliseconds);
    } else if (intent.name === "AMAZON.HelpIntent") {
        if(requestLang === "en-US")
            this.say("Welcome to the Radio del Buonsenso. Say Play to play some audio!", "You can say Play");
        else if(requestLang === "it-IT")
            this.say("Puoi dire avvia per ascoltare l'ultimo programma!. Invece puoi dire stop radio del buonsenso per interrompere la riproduzione", "Puoi dire avvia per avviare, stop radio del buonsenso per chiudere.");



    }
};

这些是我已经实现的播放和停止指令。

SimplePlayer.prototype.play = function (audioURL, offsetInMilliseconds) {
var response = {
    version: "1.0",
    response: {
        shouldEndSession: true,
        directives: [
            {
                type: "AudioPlayer.Play",
                playBehavior: "REPLACE_ALL", // Setting to REPLACE_ALL means that this track will start playing immediately
                audioItem: {
                    stream: {
                        url: audioURL,
                        token: "0", // Unique token for the track - needed when queueing multiple tracks
                        expectedPreviousToken: null, // The expected previous token - when using queues, ensures safety
                        offsetInMilliseconds: offsetInMilliseconds
                    }
                }
            }
        ]
    }
};

this.context.succeed(response);
};

// Stops the playback of Audio
SimplePlayer.prototype.stop = function (message, repromptMessage) {
var response = {
    version: "1.0",
    response: {
        shouldEndSession: true,
        outputSpeech: {
            type: "SSML",
            ssml: "<speak> " + message + " </speak>"
        },
        reprompt: {
            outputSpeech: {
                type: "SSML",
                ssml: "<speak> " + repromptMessage + " </speak>"
            }
        },
        directives: [
            {
                type: "AudioPlayer.Stop"
            }
        ]
    }
};

this.context.succeed(response);
};

当说“ Alexa，暂停”时，如何使技能停止音频？如何从说“ Alexa，恢复”时暂停的状态恢复流？

如何在音频播放器技能中正确实现AMAZON.ResumeIntent和AMAZON.PauseIntent
