Я пытаюсь овладеть навыком Alexa, а он не работает с API. Что я делаю не так (python) - PullRequest

Я пытаюсь создать навык Alexa, который обращается к API и дает некоторую общую информацию о Коронавирусе. Почему я дохожу до этого намерения, он перестает работать. Я попытался прокомментировать материал API и написать простой Hello World, и это сработало. Однако часть API все еще не работает, и я не могу понять, почему. Я импортировал те же библиотеки, скопировал и вставил их в Mu-code, изменил speak_output на печать, и это сработало.

Вот цель API.

    """Handler for Hello World Intent."""
    def can_handle(self, handler_input):
        # type: (HandlerInput) -> bool
        return ask_utils.is_intent_name("GlobalInfoIntent")(handler_input)

    def handle(self, handler_input):
        # type: (HandlerInput) -> Response
        url = "https://api.covid19api.com/summary"
        response = requests.get(url)
        json_data = response.json()
       # print(data["Global"]["NewConfirmed"])
        speak_output = (json_data["Global"]["NewConfirmed"])

        return (
            handler_input.response_builder
                .speak(speak_output)
                # .ask("add a reprompt if you want to keep the session open for the user to respond")
                .response
        )

Вот мой полный код.

Не похоже, что вы скопировали / вставили свой код, так как ваш оператор печати на самом деле будет ошибкой (должен быть json_data не data). Тем не менее, предоставленный вами код выглядит неплохо.

Я предполагаю, что speak_output содержит некоторые небезопасные символы.

Самый простой тест - попытаться вывести более простую (известную) копию. Установить speak_output = "hello world". Если это сработает, как я предполагаю, это ваша копия API.

Далее, import html, затем экранируйте свою копию API ...

        speak_output = html.escape(json_data["Global"]["NewConfirmed"])
