是否有可能让RequestInterceptor根据RequestInterceptor内部的某种逻辑来中止会话?
我有一个例程来验证用户的有效性。如果有效性检查失败,我想向用户播放一条消息并中止会话。
我看到的是,即使我尝试杀死RequestInterceptor中的连接,LaunchRequest仍然运行
简化版本如下
const Alexa = require('ask-sdk-core');
const requestInterceptor = {
var isUserOk = false;
if(!isUserOk){
process(handlerInput) {
return handlerInput.responseBuilder
.speak("You are inside the Request Interceptor")
.withShouldEndSession(true)
.getResponse();
}
}
}
const launchRequestHandler = {
canHandle(handlerInput) {
return (handlerInput.requestEnvelope.session.new &&
handlerInput.requestEnvelope.request.type === 'LaunchRequest');
},
handle(handlerInput) {
return handlerInput.responseBuilder
.speak("Hi, welcome to the test skill. What is your name?")
.reprompt("You did not respond. Please tell me your name")
.getResponse();
}
};
const skillBuilder = Alexa.SkillBuilders.custom();
exports.handler = skillBuilder
.addRequestHandlers(
launchRequestHandler,
)
.addRequestInterceptors(
requestInterceptor
)
.lambda();
有人可以告诉我是否有可能让RequestInterceptor中的逻辑杀死Session并阻止LaunchRequest处理程序运行吗?
谢谢

这是行不通的,因为拦截器不会返回响应(请注意,拦截器方法称为process()
而不是handle()
)在拦截器中,不要尝试关闭会话,而应使用{ {1}}设置名为例如的会话属性handlerInput
:
validUser
现在创建一个launchRequestBadUserHandler,在let attributes = handlerInput.attributesManager.getSessionAttributes();
attributes.validUser = isUserOk(); //call your user check function here
handlerInput.attributesManager.setSessionAttributes(attributes);
中,您要求该会话属性为false:
canHandle()
在此处理程序const attributes = handlerInput.attributesManager.getSessionAttributes();
const isUserOk = attributes.validUser;
canHandle(handlerInput) {
return (handlerInput.requestEnvelope.session.new &&
handlerInput.requestEnvelope.request.type === 'LaunchRequest' &&
!isUserOk);
函数中,发送您最初为拦截器计划的响应。不要忘记在handle()
