node.js - Google Actions sdk 不使用 MediaObject 播放音频
问题描述
我尝试使用 MediaObject 播放音频,MediaObject 没有播放给定的 mp3 音频文件,但我收到以下错误消息“必须设置 MalformedResponse 'final_response'。”
'use strict';
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const {
dialogflow,
BasicCard,
BrowseCarousel,
BrowseCarouselItem,
Button,
Carousel,
LinkOutSuggestion,
List,
MediaObject,
Suggestions,
SimpleResponse,
} = require('actions-on-google');
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
function welcome(agent) {
agent.add(`Welcome to my agent!`);
}
function fallback(agent) {
agent.add(`I didn't understand`);
agent.add(`I'm sorry, can you try again?`);
}
// // Uncomment and edit to make your own intent handler
// // uncomment `intentMap.set('your intent name here', yourFunctionHandler);`
// // below to get this function to be run when a Dialogflow intent is matched
function yourFunctionHandler(agent) {
agent.add(`This message is from Dialogflow's Cloud Functions for Firebase editor!`);
let conv = agent.conv();
conv.ask(new Suggestions('Suggestion Chips'));
conv.close(new MediaObject({
name: 'Jazz in Paris',
url: 'https://storage.googleapis.com/automotive-media/Jazz_In_Paris.mp3',
description: 'A funky Jazz tune',
icon: new Image({
url: 'https://storage.googleapis.com/automotive-media/album_art.jpg',
alt: 'Media icon',
}),
}));
conv.ask(new Suggestions(['suggestion 1', 'suggestion 2']));
}
// Run the proper function handler based on the matched Dialogflow intent name
let intentMap = new Map();
//intentMap.set('Default Welcome Intent', welcome);
//intentMap.set('Default Fallback Intent', fallback);
intentMap.set('PlaySongIntents', yourFunctionHandler);
// intentMap.set('your intent name here', googleAssistantHandler);
agent.handleRequest(intentMap);
});
我得到以下回应
"responseMetadata": {
"status": {
"code": 10,
"message": "Failed to parse Dialogflow response into AppResponse because of empty speech response",
"details": [

"@type": "type.googleapis.com/google.protobuf.Value",

}
]
}
}
}
解决方案
错误消息表明,除了要播放的音频之外,您没有包含应该说的消息。需要SimpleResponse
在音频中包含一个。
您正在混合 Dialogflow 响应和 Actions on Google 响应,这可能会混淆响应解析器。您应该将 a 添加SimpleResponse
到conv
对象作为响应的一部分。所以这部分代码可能看起来像这样:
function yourFunctionHandler(agent) {
let conv = agent.conv();
conv.ask(new SimpleResponse("Here is a funky Jazz tune"));
conv.ask(new Suggestions(['suggestion 1', 'suggestion 2']));
conv.close(new MediaObject({
name: 'Jazz in Paris',
url: 'https://storage.googleapis.com/automotive-media/Jazz_In_Paris.mp3',
description: 'A funky Jazz tune',
icon: new Image({
url: 'https://storage.googleapis.com/automotive-media/album_art.jpg',
alt: 'Media icon',
}),
}));
}
此外,您不会将Image
对象作为 . 的一部分导入require('actions-on-google')
,这就是函数运行时导致错误的原因。确保您将所有需要的对象作为require
.
