Python 3.6 和 Flask-Ask
我似乎无法让 Alexa 为我当前的爱好项目（http://github.com/michaeljdietz/jukebox）流式传输音频。
我可以通过网络浏览器手动流式传输音频，我的响应对象中的 https 流 URL 没有问题。Alexa 和 AVS 服务模拟器都以正确的语音和文本响应请求。无论如何，据我所知，该指令的格式似乎对我来说是正确的。
这是对 Alexa 的响应，应该会触发播放：
{
"version": "1.0",
"response": {
"outputSpeech": {
"text": "Playing the album The Bends by Radiohead on your jukebox",
"type": "PlainText"
},
"speechletResponse": {
"outputSpeech": {
"text": "Playing the album The Bends by Radiohead on your jukebox"
},
"directives": [
{
"playBehavior": "REPLACE_ALL",
"type": "AudioPlayer.Play",
"audioItem": {
"stream": {
"token": "334f1e7e-938d-4dea-a732-45884c6f6db9",
"url": "https://michaeljdietz.me/songs/1426",
"offsetInMilliseconds": 0
}
}
}
],
"shouldEndSession": true
}
},
"sessionAttributes": {}
}更新：对于同一个流 URL，它似乎确实有十分之 1 的工作。以下是 Alexa 失败时的响应。
