c# - Alexa Skill C#无法播放音频

Question

我有一种Alexa技能，想在发布时播放一首歌。我正在将VS2017与AWS Toolkit和AWS Lambda函数一起使用。我已经配置并构建了Alexa技能，并发布了Lambda函数，并通过Alexa Console测试和Alexa Echo进行了验证，所有这些都可以正常工作。

当我从在SkillResponse中返回文本更改为使用AudioPlayerPlay(从Alex.NET Nuget包中)返回音频指令时，我得到了看起来格式正确的JSON，但是Alexa Console测试表明其不受支持的设备和我的Alexa Echo什么也没做。

这是AWS Lambda测试中的JSON。

{
  "version": "1.0",
  "response": {
    "shouldEndSession": true,
    "directives": [
      {
        "playBehavior": "REPLACE_ALL",
        "audioItem": {
          "stream": {
            "url": "https://music.amazon.com/my/albums/You+Get+What+You+Give/YOU+GET+WHAT+YOU+GIVE/ZAC+BROWN+BAND?ie=UTF8&albumAsin=B00438BTJ6&playNow=1&trackAsin=B004386MMU",
            "token": "scrumstartsong",
            "expectedPreviousToken": null,
            "offsetInMilliseconds": 0
          }
        },
        "type": "AudioPlayer.Play"
      }
    ]
  }
}

这是Alexa Console测试中Directive:AudioPlayer.Play命令的条目

{
    "header": {
        "namespace": "AudioPlayer",
        "name": "Play",
        "messageId": "d0c18d3c-2403-4f56-a059-67f3855f4e47",

    },
    "payload": {
        "audioItem": {
            "audioItemId": "amzn1.as-ct.v1.ThirdPartySdkSpeechlet#ACRI#url#ACRI#{\"directedCustomerId\":\"amzn1.ask.account.AHGMQILIBZCL6YKVYSGTEOJGJ2B7I3FUTXBL7AZWBULBPMOA4CGW7JBRTO7AZXAWVLVDLEB4EP3XRPOZXAUVA64I66QCHGSZ5A3OK4GHP4TR6BOJVAEKXVGD7NTASS6AYD5RDCBS4JS3SH7EFGYBWS34F7TC7GFMDOWRICBA6EYYKISCVKURCUMFTSXXWZDXUVE7NG336KWDJHY\",\"modelKey\":\"amzn1.ask.skill.8e374b1d-05d8-4455-afc5-d701aed22b7d\",\"obfuscatedCustomerId\":\"A2JSZ6NNUSHRJJ\",\"token\":\"scrumstartsong\"}",
            "stream": {
                "offsetInMilliseconds": 0,
                "expiryTime": "2019-03-11T19:47:01+0000",
                "url": "https://music.amazon.com/my/albums/You+Get+What+You+Give/YOU+GET+WHAT+YOU+GIVE/ZAC+BROWN+BAND?ie=UTF8&albumAsin=B00438BTJ6&playNow=1&trackAsin=B004386MMU",
                "token": "amzn1.as-ct.v1.ThirdPartySdkSpeechlet#ACRI#url#ACRI#{\"directedCustomerId\":\"amzn1.ask.account.AHGMQILIBZCL6YKVYSGTEOJGJ2B7I3FUTXBL7AZWBULBPMOA4CGW7JBRTO7AZXAWVLVDLEB4EP3XRPOZXAUVA64I66QCHGSZ5A3OK4GHP4TR6BOJVAEKXVGD7NTASS6AYD5RDCBS4JS3SH7EFGYBWS34F7TC7GFMDOWRICBA6EYYKISCVKURCUMFTSXXWZDXUVE7NG336KWDJHY\",\"modelKey\":\"amzn1.ask.skill.8e374b1d-05d8-4455-afc5-d701aed22b7d\",\"obfuscatedCustomerId\":\"A2JSZ6NNUSHRJJ\",\"token\":\"scrumstartsong\"}"
            }
        },
        "playBehavior": "REPLACE_ALL"
    }
}

我为 token 尝试了其他(也没有)值。

我已验证是否可以让Alexa播放我在Echo上的歌曲。

我的感觉是您的代码上没有问题!到目前为止，我很高兴，Alexa开发人员控制台模拟器不支持Audio Player指令:(
