我正在尝试制作 Alexa 技能，但它不能与 API 一起使用。我在做什么错（python）

Question

我正在尝试制作一个调用 API 并提供有关冠状病毒的一般信息的 Alexa 技能。为什么我达到这个意图它停止工作。我尝试注释掉 API 的东西，并编写一个简单的 Hello World 并且成功了。但是 API 部分仍然没有，我不知道为什么。我导入了相同的库，将其复制粘贴到 Mu-code 中，将 speak_output 更改为 print，它就可以工作了。

这是 API 的意图。

    """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
        )

这是我的完整代码。

看起来您没有复制/粘贴代码，因为您的打印语句实际上会出错（应该是 json_data 而不是 data）。也就是说，您提供的代码看起来不错。

我的猜测是speak_output 包含一些不安全的字符。

最简单的测试是尝试输出更简单（已知）的副本。设置speak_output = "hello world"。如果这行得通，正如我猜测的那样，它就是你的 API 副本。

接下来，import html，然后转义您的 API 副本...

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