为了通过 webhook 路由多个意图,您将需要一个带有 express 路由器的 handler.js 文件...
const def = require('./intents/default')
const compression = require('compression')
const serverless = require('serverless-http')
const bodyParser = require('body-parser')
const { WebhookClient } = require('dialogflow-fulfillment')
const express = require('express')
const app = express()
// register middleware
app.use(bodyParser.json({ strict: false }))
app.use(function (err, req, res, next) {
res.status(500)
res.send(err)
})
app.use(compression())
app.post('/', async function (req, res) {
// Instantiate agent
const agent = new WebhookClient({ request: req, response: res })
const intentMap = new Map()
intentMap.set('Default Welcome Intent', def.defaultWelcome)
await agent.handleRequest(intentMap)
})
module.exports.server = serverless(app)
如你所见,这个 handler.js 使用 serverless-http 和 express。
您的 intent.js 函数可能看起来像这样......
module.exports.defaultWelcome = async function DefaultWelcome (agent) {
const responses = [
'Hi! How are you doing?',
'Hello! How can I help you?',
'Good day! What can I do for you today?',
'Hello, welcoming to the Dining Bot. Would you like to know what\'s being served? Example: \'What\'s for lunch at cronkhite?\'',
'Greetings from Dining Bot, what can I do for you?(Hint, you can ask things like: \'What\'s for breakfast at Annenberg etc..\' or \'What time is breakfast at Anennberg?\')',
'greetings',
'hey',
'long time no see',
'hello',
"lovely day isn't it"
]
const index = Math.floor((Math.random() * responses.length) + 1)
console.log(responses[index].text)
agent.add(responses[index].text)
}
这为您提供了通过 webhook 路由多个请求的基本框架。希望这会有所帮助。
