是否可以播放音频文件或流?
Is it possible to play audio file or stream?
是否可以使用 actions-on-google-nodejs 库播放音频文件或流?
使用 SSML 您可以 return 长达 120 秒的音频剪辑。

如果要播放mp3文件的音频(超过120s),需要使用Media Responses
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: '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: 'Ocean view',
}),
}));
为了给 Nick 的回答再增加一点,您还可以构建一个媒体响应,它允许您播放一个长音频文件(我目前正在我的应用程序中播放 50 分钟的专辑)。
您可以在 Google 的文档 here.
上找到它
Node.js 中的一个简短示例可以是:
const richResponse = app.buildRichResponse()
.addSimpleResponse("Here's song one.")
.addMediaResponse(app.buildMediaResponse()
.addMediaObjects([
app.buildMediaObject("Song One", "https://....mp3")
.setDescription("Song One with description and large image.") // Optional
.setImage("https://....jpg", app.Media.ImageType.LARGE)
// Optional. Use app.Media.ImageType.ICON if displaying icon.
])
)
.addSuggestions(["other songs"]);
然后你就可以
app.ask(richResponse)
