使用确认时的Alexa递归意向委托
使用确认时的Alexa递归意向委托
提问于 2020-07-11 22:26:33
我正在写一个阿列克谢对话与意图确认。当确认被拒绝时，我希望通过委托给这个对话框来重新启动相同的对话框。我正在进行类似于这堆栈溢出问题的描述。正如这个问题的解决方案所描述的那样，当dialogState仍然是IN_PROGRESS时，我进行委托。在我的例子中，Alexa总是用不太有意义的信息来回应，要求的技能的反应是有问题的。应用程序日志中没有错误消息。
我的技能模型和lambda代码如下：
{
"interactionModel": {
"languageModel": {
"invocationName": "hello",
"intents": [
{
"name": "UserIntent",
"slots": [
{
"name": "UserName",
"type": "AMAZON.FirstName",
"samples": [
"My name is {UserName}",
"I am {UserName}",
"{UserName}"
]
}
],
"samples": [
"My name is {UserName}",
"I am {UserName}"
]
}
],
"types": []
},
"dialog": {
"delegationStrategy": "SKILL_RESPONSE",
"intents": [
{
"name": "UserIntent",
"confirmationRequired": true,
"prompts": {
"confirmation": "Confirm.Intent.UserName"
},
"slots": [
{
"name": "UserName",
"type": "AMAZON.FirstName",
"confirmationRequired": false,
"elicitationRequired": true,
"prompts": {
"elicitation": "Elicit.Slot.UserName"
}
}
]
}
]
},
"prompts": [
{
"id": "Elicit.Slot.UserName",
"variations": [
{
"type": "PlainText",
"value": "What is your name?"
}
]
},
{
"id": "Confirm.Intent.UserName",
"variations": [
{
"type": "PlainText",
"value": "You are {UserName}. Is this right?"
}
]
}
]
}
}const DeniedUserIntentHandler = {
canHandle(handlerInput) {
const request = handlerInput.requestEnvelope.request;
return request.type === 'IntentRequest' &&
request.intent.name === 'UserIntent' &&
request.dialogState === 'IN_PROGRESS' &&
request.intent.confirmationStatus === 'DENIED';
},
async handle(handlerInput) {
const request = handlerInput.requestEnvelope.request;
const currentIntent = request.intent;
const userName = Alexa.getSlotValue(handlerInput.requestEnvelope, 'UserName');
console.log(`DeniedUserIntentHandler:
request.dialogState=${request.dialogState}, request.intent.confirmationStatus=${request.intent.confirmationStatus}, userName=${userName}`);
return handlerInput.responseBuilder
.speak('Username was not confirmed. Please try again.')
.addDelegateDirective({
name: 'UserIntent',
confirmationStatus: 'NONE',
slots: {}
})
.getResponse();
}
};我错过了什么？

您没有指定是否触发DeniedUserIntentHandler。如果错误是在DeniedUserIntentHandler内部生成的，那么它是由于Delegate Directive格式错误造成的。
您的回复应该是：
return handlerInput.responseBuilder
.speak('Username was not confirmed. Please try again.')
.addDelegateDirective({
"type": "Dialog.Delegate",
"updatedIntent": {
name:"UserIntent",
confirmationStatus:"NONE",
slots: {
UserName: {
name:"UserName",
confirmationStatus:"NONE",
source:"USER"
}
}
}
})
.getResponse();您删除意图的前一状态的原因，因为您希望从一开始就开始您的意图操作。
您也可以像这样使用代码:引用https://forums.developer.amazon.com/questions/92334/answering-no-to-intent-confirmation.html?childToView=206243#comment-206243
currentIntent.confirmationStatus = "NONE";
Object.keys(currentIntent.slots).forEach(
(slotName) => {
var slot = intent.slots[slotName];
delete slot.value;
slot.confirmationStatus = "NONE";
}
);
var delegatedirective = {"type": "Dialog.Delegate",
"updatedIntent": currentIntent};Stack Overflow用户

你现在面临的问题是真实的。亚马逊论坛中也提到了这个问题。但是，只要稍加修改，就可以实现类似的行为。为UserName激活时隙值确认，而为UserIntent激活删除确认。您的交互模型类似于如下所示：
{
"interactionModel": {
"languageModel": {
"invocationName": "demo app",
"intents": [
{
"name": "UserIntent",
"slots": [
{
"name": "UserName",
"type": "AMAZON.FirstName",
"samples": [
"My name is {UserName}",
"I am {UserName}",
"{UserName}"
]
}
],
"samples": [
"My name is {UserName}",
"I am {UserName}"
]
},
{
"name": "AMAZON.NavigateHomeIntent",
"samples": []
}
],
"types": []
},
"dialog": {
"intents": [
{
"name": "UserIntent",
"delegationStrategy": "SKILL_RESPONSE",
"confirmationRequired": false,
"prompts": {},
"slots": [
{
"name": "UserName",
"type": "AMAZON.FirstName",
"confirmationRequired": true,
"elicitationRequired": true,
"prompts": {
"confirmation": "Confirm.Slot.247378890994.1277345498514",
"elicitation": "Elicit.Slot.UserName"
}
}
]
}
],
"delegationStrategy": "ALWAYS"
},
"prompts": [
{
"id": "Elicit.Slot.UserName",
"variations": [
{
"type": "PlainText",
"value": "What is your name?"
}
]
},
{
"id": "Confirm.Slot.247378890994.1277345498514",
"variations": [
{
"type": "PlainText",
"value": "your name is {UserName} , right ?"
}
]
}
]
}
}您可以添加以下单个代码处理程序：
const UserIntenStartedHandler = {
canHandle(handlerInput) {
const request = handlerInput.requestEnvelope.request;
return request.type === 'IntentRequest' &&
request.intent.name === 'UserIntent';
},
async handle(handlerInput) {
const request = handlerInput.requestEnvelope.request;
const currentIntent = Alexa.getIntentName(handlerInput.requestEnvelope);
const slot = Alexa.getSlot(handlerInput.requestEnvelope, 'UserName');
if (slot.confirmationStatus !== 'CONFIRMED') {
return handlerInput.responseBuilder
.addDelegateDirective(request.intent)
.getResponse();
} else {
return handlerInput.responseBuilder
.speak('your Final name is ' + slot.value + '. cheers')
.withShouldEndSession(true)
.getResponse();
}
}

多亏了@tahiat的回复，我才能解决我最初的问题。在更新的意图中，时隙对象必须包含意图的插槽(没有值)。但是他的第一个代码片段包含一个错误。醚的使用
.addDirective({
"type": "Dialog.Delegate",
"updatedIntent": {
name:"UserIntent",
...
}
})或使用
.addDelegateDirective({
name:"UserIntent",
...
})因为addDelegateDirective希望有一个意图作为参数。
但现在我正面临着另一个问题。我在对话框中使用确认。在确认被拒绝后，当我回到UserIntent的初始状态时，我永远不会收到确认消息的提示。这是因为request.intent.confirmationStatus保留了它的值，即'DENIED'，尽管我在updateIntent中将它重置为'NONE'。
