阿列克谢技能在developer.amazon工作，但不在设备上？

Question

好的，这需要详细说明：首先，当我问“出发地点”的意图时，developer.amazon.com它工作得很好。当我使用真正的设备时，它称之为“unHandledIntent”。其次，当它被重新提示时，它确实工作，比如：“嘿，阿列克谢，问调用名。”在它回复未处理的消息之前，不要说任何话。然后我可以正常地说出话语，它会有反应。第三也是最后一点，它正在与“便利位置”的意图一起工作。我不确定发生了什么或者有什么不同。这是代码。谢谢！

var doc = require('dynamodb-doc');
var db = new doc.DynamoDB();

我不知道您是否仍在寻求解决方案，但我认为您的问题在于代码的嵌套。试着把东西和出口分开。正如AWS lambda指南所说，它更清洁、更易于使用。所以试试这个：

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

然后在不同的操纵者下面

var handlers = {
        'sessionStartedRequest' : function(){
            this.emit(':talk', "welcome.")
        },
        'AMAZON.StopIntent': function() {
            this.emit(':tell', "Goodbye!");
        },
        'AMAZON.CancelIntent': function() {
            this.emit(':tell', "Goodbye!");
        },
        'Unhandled': function() {
            this.emit(':ask', "I'm sorry. I didn't get that. Could you repeat it?", "Ask me a question.");
        },
        'SessionEndedRequest': function() {
            this.emit(":tell", "Goodbye!");
        },
'DepartmentLocationIntent': function () {
            var name = "";

            if (this.event.request.intent.slots.department.value) {
                name = this.event.request.intent.slots.department.value.toLowerCase().trim();
            }

            var key = {
                'name': name
            };
            var tableName = "Department";
            var params = {
                TableName: tableName,
                Key: key,
                ProjectionExpression: 'loc'
            };

            db.getItem(params, function (err, data) {
                //alexa.emit(":tell", name);
                if (err) {
                    console.log(err);
                    //alexa.emit(':tell', "Sorry! I did not catch that!");
                    alexa.emit(':tell', err);
                } else {
                    var loc = JSON.stringify(data.Item.loc);
                    alexa.emit(':tell', "The " + name + " department is in " + loc);
                }
            }, context.done);
        },

        'FacilityLocationIntent': function() {
            var name = "";
            if (this.event.request.intent.slots.facility.value) {
                name = this.event.request.intent.slots.facility.value.toLowerCase().trim();
            }
            var key = {
                'name': name
            };
            var tableName = "Facility";
            var params = {
                TableName: tableName,
                Key: key,
                ProjectionExpression: 'loc'
            };
            db.getItem(params, function(err, data) {
                if (err) {
                    console.log(err);
                    alexa.emit(':tell', "Sorry! This facility does not exist!");
                } else {
                    var response = JSON.stringify(data.Item.loc);
                    alexa.emit(':tell', name + " is located in " + response);
                }
            }, context.done);
        }
    };

希望这能解决你的问题。
