# 子路由配置
# resetful API 子路由
例如api子路由/user/getUserInfo.json，整合到主路由，加载到中间件后，请求的路径会是 http://www.example.com/api/user/getUserInfo.json
./demos/project/server/routers/api.js
/**
* restful api 子路由
*/
const router = require('koa-router')()
const userInfoController = require('./../controllers/user-info')
const routers = router
.get('/user/getUserInfo.json', userInfoController.getLoginUserInfo)
.post('/user/signIn.json', userInfoController.signIn)
.post('/user/signUp.json', userInfoController.signUp)
module.exports = routers

# 子路由汇总
./demos/project/server/routers/index.js
/**
* 整合所有子路由
*/
const router = require('koa-router')()
const home = require('./home')
const api = require('./api')
const admin = require('./admin')
const work = require('./work')
const error = require('./error')
router.use('/', home.routes(), home.allowedMethods())
router.use('/api', api.routes(), api.allowedMethods())
router.use('/admin', admin.routes(), admin.allowedMethods())
router.use('/work', work.routes(), work.allowedMethods())
router.use('/error', error.routes(), error.allowedMethods())
module.exports = router

# app.js加载路由中间件
./demos/project/server/app.js
const routers = require('./routers/index')
// 初始化路由中间件
app.use(routers.routes()).use(routers.allowedMethods())
