我正在尝试播放播客的mp3剧集,并根据此页面上有关媒体响应的说明添加图片。 https://developers.google.com/actions/assistant/responses#media_responses
错误与云功能有关,如下所示。
The deployment of your Cloud Function failed:
Function load error: Code in file index.js can't be loaded.
Is there a syntax error in your code?

我是Google上的炬新手,我不知道从哪里开始排除故障。我的理解是,我可以使用Fulfillment中的内联编辑器调用和播放此文件。
下面是我当前在内联编辑器中的代码。
非常感谢任何关于从这里去的地方的意见。谢谢道格
'use strict';
const {dialogflow} = require('actions-on-google');
const functions = require('firebase-functions');
const app = dialogflow({debug: true});
if (!conv.surface.capabilities.has('actions.capability.MEDIA_RESPONSE_AUDIO')) {
conv.ask('Sorry, this device does not support audio playback.');
return;
}
conv.ask(new MediaObject({
name: 'The Wiggins Personality Model',
url: 'https://storage.googleapis.com/voicemarketing-assets02/v01/media/Ep001-VoiceMarketing-WigginsPersonalityModel.mp3',
description: 'How Clifford Nass used the Wiggins Personality Model for voice.',
icon: new Image({
url: 'https://storage.googleapis.com/voicemarketing-assets02/v01/media/Ep001-VoiceMarketing-EpKeyart-1400x933-brain.png',
alt: 'Media icon',
}),
}));
app.intent('play.episode', (conv) => {
const mediaStatus = conv.arguments.get('MEDIA_STATUS');
let response = 'Unknown media status received.';
if (mediaStatus && mediaStatus.status === 'FINISHED') {
response = 'Hope you enjoyed the tunes!';
}
conv.ask(response);
});
exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app);
如堆栈跟踪所示:
Detailed stack trace: ReferenceError: conv is not defined
conv
作为对象仅存在于app.intent
的范围内,作为回调的一部分。
作为初始webhook设置的一部分,您在该范围之外调用conv.ask
。任何会话位都应该封装在app.intent
中,这样它们只有在触发给定意图时才会运行。在这里,您可以看到您的代码段已移至intent处理程序中。
app.intent('play-media', conv => {
if (!conv.surface.capabilities.has('actions.capability.MEDIA_RESPONSE_AUDIO')) {
conv.ask('Sorry, this device does not support audio playback.');
return;
}
conv.ask(new MediaObject({
name: 'The Wiggins Personality Model',
url: 'https://storage.googleapis.com/voicemarketing-assets02/v01/media/Ep001-VoiceMarketing-WigginsPersonalityModel.mp3',
description: 'How Clifford Nass used the Wiggins Personality Model for voice.',
icon: new Image({
url: 'https://storage.googleapis.com/voicemarketing-assets02/v01/media/Ep001-VoiceMarketing-EpKeyart-1400x933-brain.png',
