从意图中获取Alexa Slot值-Java 学习之路

我正在努力构建一个Alexa技能，并且在将我的插槽值从intent对象中取出时遇到了障碍 . 意图对象JSON如下所示：

"intent": {
    "name": "string",
    "slots": {
      "string": {
        "name": "string",
        "value": "string"
      }
   }
}

我的问题是，第一个“字符串”值将用于识别插槽？文档包含：

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.

这是否意味着获取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 - 所以如果通过名称访问特定插槽的方式，名称参数将多余（您已经知道访问插槽的名称 . ）

有谁知道如何访问Alexa技能中的各个槽值？

顺便说一句，我正在使用NodeJS来获得这项技能 .

让我们假设我们在交互模型中有一个名称创建 Session 请求的意图 .

"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"
        ]
    }
]

而你想用lambda代码访问它 . 您可以使用以下行 .

'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
},

this 是Object包含来自alexa的完整JSON请求 . 所以你可以使用slotname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

由于我遇到了很多麻烦，一个更具体的答案（现在）是：

'PersonIntent': function () {
    var text = 'Hello ' + this.event.request.intent.slots.FirstPerson.value;

    this.emit(':tell', text);
},

使用此意图架构：

{
    "intents": [
        {
            "intent": "PersonIntent",
            "slots": [
                {
                    "name": "FirstPerson",
                    "type": "AMAZON.DE_FIRST_NAME"
                }
            ]
        }
    ]
}

这是您的结构意图的示例：
```
"intent": {
    "name": "MovieIntent",
    "slots": {
     "string": {
        "name": "Movie",
        "value": "Titanic"
     }
  }
}
```
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） . 你将以这种方式获得 Value ：
```
var movieSlot = intent.slots.Movie.value;
```
