使用 python 调用 alexa 的定时器 api 不工作

Question

我尝试了以下代码通过 api 调用 alexa 的计时器：

timer = {
    "duration": "PT15S",
    "timerLabel": "Change name",
    "creationBehavior": {
        "displayExperience": {
            "visibility": "VISIBLE"
        }
    },
    "triggeringBehavior": {
        "operation": {
            "type": "ANNOUNCE", 
            "textToAnnounce": [
                {
                    "locale": "en-US",
                    "text": "Break time"
                }
            ]
        },
        "notificationConfig": {
            "playAudible": True 
        }
    }
}


class TimerHandler(AbstractRequestHandler):
    def can_handle(self, handler_input):
        return ask_utils.is_intent_name("TimerHandler")(handler_input)

    def handle(self, handler_input):
        request_envelope = handler_input.request_envelope
        permissions = request_envelope.context.system.user
       
        if not (permissions):        
            return (
                    handler_input.response_builder
                    .add_directive({
                        type: "Connections.SendRequest",
                        name: "AskFor",
                        payload: {
                        "@type": "AskForPermissionsConsentRequest",
                        "@version": "1",
                        "permissionScope": "alexa::alerts:timers:skill:readwrite"
                        },
                        token: "<string>"
                        })
                    .speak("This skill needs permission to access your timer")
                    .ask()
                    .response
                    )
        else:
            return requests.post("https://api.amazonalexa.com/v1/alerts/timers", timer),

requests.status_code

但是，我收到以下错误。

 Error received:
    [ERROR] AttributeError: 'Response' object has no attribute 'deserialized_types'
    Traceback (most recent call last):
      File "/var/task/ask_sdk_core/skill_builder.py", line 112, in wrapper
        return skill.serializer.serialize(response_envelope)  # type:ignore
      File "/var/task/ask_sdk_core/serialize.py", line 125, in serialize
        return {key: self.serialize(val) for key, val in iteritems(obj_dict)}
      File "/var/task/ask_sdk_core/serialize.py", line 125, in <dictcomp>
        return {key: self.serialize(val) for key, val in iteritems(obj_dict)}
      File "/var/task/ask_sdk_core/serialize.py", line 114, in serialize
        k: k for k in obj.deserialized_types.keys()

有人能帮帮我吗:(这对我来说真的很重要，因为我不知道是什么问题，也不知道是什么错误。

Answer 1

您的 handle 方法 return 结果类型错误。

它必须 return ask_sdk_model.response.Response 类型的实例，并且如果条件 if not permissions 为真，它会正确执行。但如果它是假的，它 returns requests.models.Response 实例。尽管这些类具有相同的名称，但它们来自不同的框架并且不兼容。

也许您需要处理此 POST 请求的响应，然后 return 需要的结果作为 ask_sdk_model.response.Response 实例，如下所示：

return handler_input.response_builder.response
