在Flask-Ask Alexa Echo Show中检测支持的接口

Question

我正在尝试建立一个回声显示屏幕启用和回声点音频仅语音技能。显然，响应指令必须根据设备进行更改，否则将导致"Alexa having trouble accessing the skill“。

如何确定Flask-ASK中支持的接口？

...
  "context": {
    "System": {
      "application": {
        "applicationId": "<value>"
      },
      "user": {
        "userId": "amzn1.ask.account.<value>"
      },
      "device": {
        "supportedInterfaces": {
          "Display": {},
          "AudioPlayer": {},
          "VideoApp": {}
        }
      }
    }
  },
...

Answer 1

像这样

def has_screen():
if context.System.device.supportedInterfaces.Display is None:
        return False
    else:
        return True
