Getting an Alexa Slot value out of an intent

Question

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:

"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:

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.)

Does anyone know how I go about accessing individual slot values in an Alexa skill?

I'm using NodeJS for this skill by the way.

Answer 1

Since I had a lot of trouble with this, a more concrete answer (now) is:

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

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

With this intent schema:

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