使用Alexa流音频的最简单示例 [英] Simplest example for streaming audio with Alexa

问题描述

我正在尝试使用新的流音频API。以下回应有效吗？在设备上进行测试时，出现技能有问题错误。

I'm trying to get the new streaming audio API going. Is the following response valid? I'm getting a "there was a problem with the skill" error when I test it on my device.

这是我的AWS-lambda函数的代码：

Here is the code for my AWS-lambda function:

def lambda_handler(event, context):
    return {
        "response": {
            "directives": [
                {
                    "type": "AudioPlayer.Play",
                    "playBehavior": "REPLACE_ALL",
                    "audioItem": {
                        "stream": {
                            "token": "12345",
                            "url": "http://emit-media-production.s3.amazonaws.com/pbs/the-afterglow/2016/08/24/1700/201608241700_the-afterglow_64.m4a",
                            "offsetInMilliseconds": 0
                        }
                    }
                }
            ],
            "shouldEndSession": True
        }
    }

推荐答案

以下代码对我有用：

def lambda_handler(event, context):
    return {
        "response": {
            "directives": [
                {
                    "type": "AudioPlayer.Play",
                    "playBehavior": "REPLACE_ALL",
                    "audioItem": {
                        "stream": {
                            "token": "12345",
                            "url": "https://emit-media-production.s3.amazonaws.com/pbs/the-afterglow/2016/08/24/1700/201608241700_the-afterglow_64.m4a",
                            "offsetInMilliseconds": 0
                        }
                    }
                }
            ],
            "shouldEndSession": True
        }
    }
]

唯一的区别是URL是https而不是http。

The only difference is that the URL is https rather than http.

请勿放置如果在技能模拟器中不起作用，请关闭。尚未升级，无法与流音频一起使用。您甚至在那里都看不到指令。但是，当与您的设备一起使用时，它应该可以工作。

Don't be put off if it doesn't work in the skill simulator. That hasn't been upgraded yet to work with streaming audio. You won't even see your directives there. But it should work when used with your device.
