Question

我有多个设备将音频流式传输到我的服务器。

我的服务器正在将音频发送到我的自定义技能

如何将关于设备所在房间的额外状态传递给适配器，例如“房间名称”？

我的多部分请求包括：

{
    'context': [
        {
            'header': {
                'namespace': 'AudioPlayer',
                'name': 'PlaybackState'
            },
            'payload': {
                'token': '',
                'offsetInMilliseconds': 0,
                'playerActivity': 'IDLE'
            }
        },
        {
            'header': {
                'namespace': 'Speaker',
                'name': 'VolumeState'
            },
            'payload': {
                'volume': 100,
                'muted': False,
            }
        },
        {
            'header': {
                'namespace': 'SpeechSynthesizer',
                'name': 'SpeechState'
            },
            'payload': {
                'token': '',
                'offsetInMilliseconds': 0,
                'playerActivity': 'FINISHED'
            }
        }
    ],
    'event': {
        'header': {
            'namespace': 'SpeechRecognizer',
            'name': 'Recognize',
            'messageId': 'my-messageId',
            'dialogRequestId': 'my-dialogRequestId',
        },
        'payload': {
            'profile': 'CLOSE_TALK',
            'format': 'AUDIO_L16_RATE_16000_CHANNELS_1'
        }
    }
}

我尝试在上下文中传递任意额外的标题，例如，

[
    'header': {
        'namespace': 'MyCustomSkill',
        'name': 'RoomState'
    },
    'payload': {
        'name': 'kitchen',
        'temperature': '40'
    }
]

但适配器无法访问这些额外的标头。请求如下所示：

                              }
                           }
                        ],
                        "status": {

                        }
                     }
                  ]
               },
               "name": "ROOM",
               "confirmationStatus": "NONE"
            }
         },

      }
   },
   "context": {
      "AudioPlayer": {
         "playerActivity": "IDLE"
      },
      "System": {

            "supportedInterfaces": {
               "AudioPlayer": {}
            }
         },
         "application": {
            "applicationId": "my-application-id"
         }
      }
   },
   "version": "1.0",
   "session": {
      "user": {
         "userId": "my-user-id"
      },
      "sessionId": "amzn1.echo-api.session.8c3e0d80-69e3-49ad-a981-d1073e0100b2",
      "new": true,
      "application": {
         "applicationId": my-application-id"
      }
   }
}

这可以用上下文来实现吗？

Answer 1

如果您希望有上下文，可以创建状态处理程序

或者你可以简单地使用

this.attributes存储您所需的信息。
