router.use('/', (req, res, next) => {
    console.log(req.body)
    next() // will run next middleware
})

router.use('/', (req, res, next) => {)
    res.body = {hello: 'world'} // res.body will sending to request client
    res.end() // tell app to stop middleware and send response data
}

router.use(router)

const router = new Router()
router.use('abc', (req, res, next)=>{
    res.body = {success: 1}
    res.end()
})

const router2 = new Router()

router2.use('test', router)


// now , clients can request 'SERVICENAME/test/abc' and
got response '{"success": 1}'

app.use(router)

app.connect(options)

app.connect({

})

app.request(url, requestBody)

// write in async/await
const response = app.request('/account/profile', {userId: 1})
console.log(response.body) // {profile: {name: 'hansel', gender: 'man'}}

// write in Promise
app.request('/account/profile', {userId: 1})
    .then((response)=>{
        console.log(response.body)
    })

// account means app's appName, defined in key. sea demo/data/service
// /profile means app's router, defined in app

hub.start()
