如何解决Alexa Skill S3 在参数中缺少必需的密钥桶
我正在尝试根据 Cake Time Tutorial 创建一项技能,但是每当我尝试调用我的技能时,我都会遇到一个我不知道为什么的错误。
const LaunchRequestHandler = {
canHandle(handlerInput) {
console.log(`Can Handle Launch Request ${(Alexa.getRequestType(handlerInput.requestEnvelope) === "LaunchRequest")}`);
return (
Alexa.getRequestType(handlerInput.requestEnvelope) === "LaunchRequest"
);
},handle(handlerInput) {
const speakOutput =
"Bem vindo,que série vai assistir hoje?";
console.log("handling launch request");
console.log(speakOutput);
return handlerInput.responseBuilder
.speak(speakOutput)
.reprompt(speakOutput)
.getResponse();
},};
它应该只提示一条葡萄牙语的消息“Bem vindo,que série vaiassisir hoje?”但它出于某种原因尝试访问 amazon S3 存储桶并在控制台上打印此错误。

}
----------------------
我从堆栈错误中删除了一些 ID 信息,但我认为它们与目的无关。
我能想到的唯一调用是当我在 alexa Skill Builder 中添加 S3 适配器时。
exports.handler = Alexa.SkillBuilders.custom()
.withapiclient(new Alexa.Defaultapiclient())
.withPersistenceAdapter(
new persistenceAdapter.S3PersistenceAdapter({
bucketName: process.env.S3_PERSISTENCE_BUCKET,})
)
.addRequestHandlers(
LaunchRequestHandler,marcaEpisodioIntentHandler,HelpIntentHandler,CancelAndStopIntentHandler,SessionEndedRequestHandler,IntentReflectorHandler // make sure IntentReflectorHandler is last so it doesn't override your custom intent handlers
)
.addRequestInterceptors(marcaEpisodioInterceptor)
.addErrorHandlers(ErrorHandler)
.lambda();
这些是我创建的 Intent Intents
这是应该处理它们的函数。
const Alexa = require("ask-sdk-core");
const persistenceAdapter = require("ask-sdk-s3-persistence-adapter");
const intentName = "marcaEpisodioIntent";
const marcaEpisodioIntentHandler = {
canHandle(handlerInput) {
console.log("Trying to handle wiht marca episodio intent");
return (
Alexa.getRequestType(handlerInput.requestEnvelope) !== "LaunchRequest" &&
Alexa.getRequestType(handlerInput.requestEnvelope) === "IntentRequest" &&
Alexa.getIntentName(handlerInput.requestEnvelope) === intentName
);
},async chandle(handlerInput) {
const serie = handlerInput.requestEnvelope.request.intent.slots.serie.value;
const episodio =
handlerInput.requestEnvelope.request.intent.slots.episodio.value;
const temporada =
handlerInput.requestEnvelope.request.intent.slots.temporada.value;
const attributesManager = handlerInput.attributesManager;
const serieMark = {
serie: serie,episodio: episodio,temporada: temporada,};
attributesManager.setPersistentAttributes(serieMark);
await attributesManager.savePersistentAttributes();
const speakOutput = `${serie} marcada no episódio ${episodio} da temporada ${temporada}`;
return handlerInput.responseBuilder.speak(speakOutput).getResponse();
},};
module.exports = marcaEpisodioIntentHandler;
任何帮助将不胜感激。
解决方法
相反,它出于某种原因尝试访问 amazon S3 存储桶
首先,在轮询意图处理程序的 canHandle
函数之前,每次使用时都会加载和配置持久性适配器。然后在轮询它们中的任何一个之前,在 RequestInterceptor
中使用持久性适配器。
如果那里有问题,它会在您到达 LaunchRequestHandler
之前中断,这就是正在发生的事情。
其次,您是在 Alexa 开发者控制台中构建 Alexa 托管的技能还是通过 AWS 托管自己的 Lambda?
Alexa 托管会为您创建大量资源,包括 Amazon S3 存储桶和 Amazon DynamoDb 表,然后确保它为您创建的 AWS Lambda 具有必要的角色设置和其环境变量中的正确信息。
>如果您通过 AWS 托管自己的,您的 Lambda 将需要一个对您的 S3 资源具有读/写权限的角色,并且您需要将存储持久值的存储桶设置为您的环境变量Lambda(或将 process.env.S3_PERSISTENCE_BUCKET
替换为包含存储桶名称的字符串)。
