所以我写了一个意图的处理程序，用户要求Alexa推荐一项服务，即“Alexa你能推荐一名水管工”。问题是，Alexa会触发其默认推荐操作。
对话如下：
用户：Alexa打开布加勒斯特的洞察力
Alexa：嗨，欢迎来到Bucharest Insight，你好吗？你可以问我关于当地新闻的问题或者向我询问推荐。
网友：我需要一个水管工
Alexa：这里有一些顶级的
我期待我的getRecommendationIntentHandler被触发，因为我已正确设置了意图（参见下面的JSON） - "I need a {serviceName}",
Alexa的结果似乎是响应中的构建，而不是下面的自定义intent处理程序：
const getRecommendationIntentHandler = {
canHandle(handlerInput) {
return handlerInput.requestEnvelope.request.type === 'IntentRequest'
&& handlerInput.requestEnvelope.request.intent.name === 'getRecommendationIntent';
},
handle(handlerInput) {
console.log('Called getRecommendationIntentHandler');
const responseBuilder = handlerInput.responseBuilder;
const filledSlots = handlerInput.requestEnvelope.request.intent.slots;
// Get the filled slots inputted by the user
const slotValues = getSlotValues(filledSlots);
console.log(JSON.stringify(slotValues));
const speechText = 'getRecommendationIntentHandler called';
return responseBuilder
.speak(speechText)
.getResponse();
},
};

您的第一个回复没有shouldEndSession参数。如果未提供，则默认为true。这意味着，一旦您的回复被阅读，Alexa将结束会话并关闭技能。你已不在技能范围内了。每当您希望Alexa等待用户响应时，通过将shouldEndSession参数设置为false来保持会话处于活动状态。
你的第一个回应应该是这样的：
{
"body": {
"version": "1.0",
"response": {
"outputSpeech": {
"type": "SSML",
"ssml": "<speak>Hi, welcome to Bucharest Insight, how are you ? you can ask me questions about the local news or ask me for a recommendation</speak>"
},
"shouldEndSession": false
},
"sessionAttributes": {},
"userAgent": "ask-node/2.0.5 Node/v8.10.0"
}
}
好处是，您不必手动设置此参数，SDK将负责处理。为此使用了一个责备。在您的回复中包含重新提示是一个很好的设计。
return responseBuilder
.speak(speechText)
.reprompt(repromptSpeechOutput)
.getResponse();
如果你不想使用reprompt，你可以使用withShouldEndSession(false)。
