我只是想做一个Alexa技能，而不是API。我做错了什么（python）

Question

我想做一个Alexa技巧，调用API并提供一些关于冠状病毒的一般信息。为什么我要达到这个目的？它停止工作了。我试着对API的内容进行评论，并让write编写一个简单的Hello World，这很有效。然而，API部分仍然没有，我不明白为什么。我导入了相同的库，复制并粘贴到Mu代码中，将speak_输出更改为print，它工作了

下面是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
        )

这是我的全部代码

Answer 1

看起来您没有复制/粘贴代码，因为print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"。如果这样做有效的话，正如我猜的那样，那就是你的API拷贝了

接下来，import html，然后转义您的API副本

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