第一技能，只是errorHandler

问题描述 投票：1回答：1

我想编写我的第一个Alexa技能，但是我的初衷并不是正常工作。错误处理程序进入并响应：“ Sorry，...”

我想做一个飞镖计算器，第一个意图应该返回：

"Ok ${spieleranzahl} Spieler, wie viele Punkte sollen gespielt werden?"

英语：

"Ok ${numerOfPlayers} players, how many points are we going to play?"

这是我的js代码，有人可以告诉我我做错了吗？ （请不要介意JSON的间距问题）

您正在注销失败原因的堆栈跟踪，是否尝试过在cloudwatch日志中查找错误，因为它会缩小范围？

虽然可以立即使用，但我可以看到您的插槽称为Spieleranzahl，但是在您尝试访问它的代码中，您可以使用spieleranzahl

这里是正确的处理程序：

//ErfasseSpieleranzahlHandler
const ErfasseSpieleranzahlHandler = {
    canHandle(handlerInput) {
        return Alexa.getRequestType(handlerInput.requestEnvelope) === 'IntentRequest'
            && Alexa.getIntentName(handlerInput.requestEnvelope) === 'ErfasseSpieleranzahl';
    },
    handle(handlerInput) {
        const spieleranzahl = handlerInput.requestEnvelope.request.intent.slots.Spieleranzahl.value;

        const speakOutput = `Ok ${spieleranzahl} Spieler, wie viele Punkte sollen gespielt werden?`;
        return handlerInput.responseBuilder
            .speak(speakOutput)
            //.reprompt(repromtText)
            .getResponse();
    }
};

我遇到同样的问题。我想跟进。我确定我也出了点问题。
