无论我问什么，我的 Alexa 意图都没有定义槽

Question

我正在使用自定义 Lambda 函数来处理我的自定义 Alexa 技能。我有一个插槽，我想捕获它。不幸的是，意图槽从未填充任何值，而且似乎被忽略了，尽管在请求中。

这是我的代码（注意：JSON.stringify 可以帮助我调试）：

'use strict';
var Alexa = require("alexa-sdk");

exports.handler = function(event, context, callback) {
    var alexa = Alexa.handler(event, context);
    alexa.registerHandlers(handlers);
    alexa.execute();
};

var handlers = {
    'LaunchRequest': function () {
        this.emit('Snow');
    },
    'Snow': function () {
        var place = this.event.request.intent.slots.Place;

        var text = 'Over the next 9 days you can expect 12 centimeters of snowfall in '+ JSON.stringify(place) +'.  The upper piste has a depth of 75 centimeters and the lower piste has a depth of 35 centimeters.  All 19 lifts are currently open.';

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

我有一个名为 "Snow" 的 Intent 和一个名为 "Place" 的插槽。这是我的交互模型：

{
    "interactionModel": {
        "languageModel": {
            "invocationName": "ski club",
            "intents": [
                {
                    "name": "AMAZON.FallbackIntent",
                    "samples": []
                },
                {

                    "samples": []

                    "samples": []
                },
                {
                    "name": "AMAZON.NavigateHomeIntent",
                    "samples": []
                },
                {
                    "name": "Snow",
                    "slots": [
                        {
                            "name": "Place",
                            "type": "AMAZON.City"
                        }
                    ],
                    "samples": [
                        "how the powder is",
                        "what the powder is like",
                        "how the snow is",
                        "what the snow is like",
                        "snow conditions",

                        "snow fall",

                        "the snow"
                    ]
                }
            ],
            "types": []
        },
        "dialog": {
            "intents": [
                {
                    "name": "Snow",
                    "confirmationRequired": false,
                    "prompts": {},
                    "slots": [
                        {
                            "name": "Place",
                            "type": "AMAZON.City",
                            "confirmationRequired": false,
                            "elicitationRequired": true,
                            "prompts": {
                                "elicitation": "Elicit.Slot.115004419453.153941565683"
                            }
                        }
                    ]
                }
            ]
        },
        "prompts": [
            {
                "id": "Elicit.Slot.115004419453.153941565683",
                "variations": [
                    {
                        "type": "PlainText",
                        "value": "Where would you like to know about the snow?"
                    }
                ]
            }
        ]
    }
}

我希望能够问：

Alexa ask my app how the snow is in Morzine

而且我希望得到来自我的 Lambda 函数的静态文本的回复，包括插入的名称。但是，我得到以下信息：

{
    "body": {
        "version": "1.0",
        "response": {
            "outputSpeech": {
                "type": "SSML",
                "ssml": "<speak> Over the next 9 days you can expect 12 centimeters of snowfall in {\"name\":\"Place\",\"confirmationStatus\":\"NONE\"}.  The upper piste has a depth of 75 centimeters and the lower piste has a depth of 35 centimeters.  All 19 lists are currently open. </speak>"
            },
            "shouldEndSession": true
        },
        "sessionAttributes": {},
        "userAgent": "ask-nodejs/1.0.25 Node/v8.10.0"
    }
}

似乎Place从来没有value。

如果我完全省略 Place 插槽，我会得到完全相同的响应：

Alexa ask my app how the snow is

在这里我希望被要求提供一个位置。

这是来自 Alexa 的 JSON 输入（我编辑了一些键）：

Answer 1

我的意图需要包括广告位本身，它并不像我想的那样假设在那里。这是通过附加 {Place}.

来完成的

无论我问什么，我的 Alexa 意图都没有定义槽

My Alexa intent has no slot defined, no matter what I ask
