为什么我应该在Google Node.js客户端库中的Actions中的actionsdk（）之上使用dialogflow（）

Question

Based on the V1 to V2 Node.js Client Library Migration guide there are two ways of listening to conversations

so the following code from V1

const {DialogflowApp } = require('actions-on-google');

const actionMap = new Map();

actionMap.set('input.welcome', app => {   app.ask('How are you?'); });

...

can be replaced with either the dialogflow module

const { dialogflow } = require('actions-on-google');
const app = dialogflow();

app.intent('Default Welcome Intent', conv => {   conv.ask('How are you?'); });

or Actions SDK module

const { actionssdk } = require('actions-on-google');
const app = actionssdk();

app.intent('actions.intent.MAIN', conv => {   conv.ask('How are you?'); });

In the first case (dialogflow) you recongize the Intent by its name but at the second (actionSdk) you recognize it from the actions name.

Why should I use one over the other and what are the benefits and limitations of each method?

Answer 1

Both libraries will deliver the transcription of what the user of your Action has said. Which library you use depends on how you intend to understand the text - to make sense of it and react accordingly. If you plan to parse it in a bespoke manner or if you have your own natural language processor (aka NLP/NLU) you use the Actions SDK. If you don't you can use Dialog Flow as the NLP and its library.
