Getting an Alexa Slot value out of an intent
提问by Bill L
I'm working to build an Alexa skill and have run into a roadblock on getting my slot values out of the intent object. The intent object JSON looks like so:
我正在努力构建 Alexa 技能，但在从意图对象中获取我的槽值时遇到了障碍。意图对象 JSON 如下所示：
"intent": {
"name": "string",
"slots": {
"string": {
"name": "string",
"value": "string"
}
}
}
My question is what will that first "string" value be to identify the slots? The documentation has this:
我的问题是第一个“字符串”值是什么来标识插槽？文档有这个：
A map of key-value pairs that further describes what the user meant based on a predefined intent schema. The map can be empty.
The key is a string that describes the name of the slot. Type: string.
The value is an object of type slot. Type: object. See Slot Object.
Does this mean the key to get the slot is the name I set in the Interaction Model? The only reason I'm hesitant to think that is because we already have a name object in the slot, which is definitely the name of the slot -- so if the way to access a specific slot was via the name, the name parameter would be redundant (you already know the name from accessing the slot.)
这是否意味着获得插槽的关键是我在交互模型中设置的名称？我犹豫不决的唯一原因是因为我们已经在插槽中有一个名称对象，这绝对是插槽的名称——所以如果访问特定插槽的方式是通过名称，则名称参数将是多余的（您已经通过访问插槽知道了名称。）
Does anyone know how I go about accessing individual slot values in an Alexa skill?
有谁知道我如何访问 Alexa 技能中的各个插槽值？
I'm using NodeJS for this skill by the way.
顺便说一下，我正在使用 NodeJS 来完成这项技能。

Since I had a lot of trouble with this, a more concrete answer (now) is:
由于我在这方面遇到了很多麻烦，更具体的答案（现在）是：
'PersonIntent': function () {
var text = 'Hello ' + this.event.request.intent.slots.FirstPerson.value;
this.emit(':tell', text);
},
With this intent schema:
有了这个意图架构：
{
"intents": [
{
"intent": "PersonIntent",
"slots": [
{
"name": "FirstPerson",
"type": "AMAZON.DE_FIRST_NAME"
}
]
}
]
}

This is an example of an intent with your structure:
这是您的结构意图的示例：
"intent": {
"name": "MovieIntent",
"slots": {
"string": {
"name": "Movie",
"value": "Titanic"
}
}
}
So, this means that the Intent you are using is named: Movie Intent (the one you set in your Interaction Model). And you will get the value this way:
因此，这意味着您使用的 Intent 被命名为：Movie Intent（您在交互模型中设置的那个）。您将通过以下方式获得价值：
var movieSlot = intent.slots.Movie.value;

As of Jul, 2019: You can access it in your intent handler as follows
截至 2019 年 7 月：您可以在您的意图处理程序中访问它，如下所示
if (handlerInput.requestEnvelope.request.intent.slots.SLOTNAME === undefined) {
text = 'Hello! SLOTNAME not identified';
} else {
text = 'Hello!, SLOTNAME identified: ' + handlerInput.requestEnvelope.request.intent.slots.SLOTNAME.value;
}
Replace SLOTNAMEwith your slot name.
It is also very important that undefinedis just as it is as an object, and not undefined
替换SLOTNAME为您的插槽名称。同样非常重要的undefined是，就像作为一个对象一样，而不是undefined

Lets assume we have a intent with name create meeting request in interaction model.
让我们假设我们有一个意图，在交互模型中创建会议请求。
"intents": [
{
"name": "CreateMeetingRequest",
"slots": [
{
"name": "meetingdate",
"type": "AMAZON.DATE",
"samples": [
"{meetingdate} at {meetingTime} for {duration}",
"{meetingdate} at {meetingTime}",
"{meetingdate} and {meetingTime}",
"{meetingdate}"
]
},
{
"name": "meetingTime",
"type": "AMAZON.TIME",
"samples": [
"{meetingTime} for {duration}",
"{meetingTime}"
]
},
{
"name": "duration",
"type": "AMAZON.DURATION",
"samples": [
"{duration}"
]
},
{
"name": "subject",
"type": "AMAZON.SearchQuery",
"samples": [
"{subject}"
]
},
{
"name": "toName",
"type": "AMAZON.US_FIRST_NAME",
"samples": [
"{toName}"
]
}
],
"samples": [
"meeting invite",
"set up meeting",
"setup meeting",
"{meetingdate} at {meetingTime}",
"create meeting with {toName}",
"schedule a meeting with {toName} on {meetingdate} at {meetingTime} for {duration}",
"Setup meeting with {toName}",
"create meeting",
"Setup meeting on {meetingdate} at {meetingTime}",
"Setup new meeting",
"create meeting request"
]
}
]
And you wanna access it in lambda code. You can use below lines.
你想在 lambda 代码中访问它。您可以使用以下几行。
'CreateMeetingRequest': function () {
const toName = (this.event.request.intent.slots.toName.value ? this.event.request.intent.slots.toName.value.toLowerCase() : null);
const subject = (this.event.request.intent.slots.subject.value ? this.event.request.intent.slots.subject.value.toLowerCase() : null);
const meetingdate = (this.event.request.intent.slots.meetingdate.value ? this.event.request.intent.slots.meetingdate.value : null);
const meetingTime = (this.event.request.intent.slots.meetingTime.value ? this.event.request.intent.slots.meetingTime.value : null);
const duration = (this.event.request.intent.slots.duration.value ? this.event.request.intent.slots.duration.value : null);
console.log("toName:",toName,", meetingdate:",meetingdate,", meetingTime:", meetingTime);
//your business logic
},
thisis the Object contains complete JSON request from alexa. So you can access any slot by using slotname
Eg: if we want to access subject slotthen we can use this.event.request.intent.slots.subject.value
this是包含来自 alexa 的完整 JSON 请求的对象。所以你可以通过使用 slotname 来访问任何插槽 例如：如果我们想访问subject slot那么我们可以使用this.event.request.intent.slots.subject.value
