Koa搭建本地测试服务器

1.在项目根目录安装

koa

、

koa-router

2.新建

server.js

文件

const Koa = require('koa')
const Router = require('koa-router')
const KoaBody = require('koa-body')
KoaBody({multipart: true})

const app = new Koa()
const router = new Router()

//首页————广告（超值特惠）
let homeAdData = require('./home/ad')
router.get('/api/homeAd', (ctx, next) => {
  ctx.body = homeAdData
})

//首页————推荐列表（猜你喜欢）
let homeListData = require('./home/list.js')
router.get('/api/homeList/:city/:page', function (ctx) {
  const params = ctx.params
  const paramsCity = params.city
  const paramsPage = params.page
  console.log(`当前城市：${paramsCity} 当前页数：${paramsPage}`)

  ctx.body = homeListData
})

// 搜索结果页————搜索结果 - 三个参数
let searchListData = require('./search/list.js')
router.get('/api/search/:page/:city/:category/:keyword', function (ctx) {
  const params = ctx.params
  const paramsPage = params.page
  const paramsCity = params.city
  const paramsCategory = params.category
  const paramsKeyword = params.keyword

  console.log(
    `当前页数：${paramsPage} 当前城市：${paramsCity} 当前类别：${paramsCategory} 关键字：${paramsKeyword}`)

  ctx.body = searchListData
})

// 搜索结果页————搜索结果 - 两个参数
router.get('/api/search/:page/:city/:category', function (ctx) {
  const params = ctx.params
  const paramsPage = params.page
  const paramsCity = params.city
  const paramsCategory = params.category

  console.log(`当前页数：${paramsPage} 当前城市：${paramsCity} 当前类别：${paramsCategory}`)

  ctx.body = searchListData
})

// 详情页————商户信息
let detailInfo = require('./detail/info.js')
router.get('/api/detail/info/:id', function (ctx) {
  const params = ctx.params
  const id = params.id

  ctx.body = detailInfo
})

// 详情页————用户评论
const detailComment = require('./detail/comment.js')
router.get('/api/detail/comment/:page/:id', function (ctx) {
  const params = ctx.params
  const page = params.page
  const id = params.id

  console.log(`商户id:${id} 当前页数:${page}`)

  ctx.body = detailComment
})

//订单列表
const orderList = require('./orderlist/orderList.js')
router.get('/api/orderList/:username', function (ctx) {
  const params = ctx.params
  const username = params.username

  console.log(`用户名：${username}`)

  ctx.body = orderList
})

//提交评论
router.post('/api/submitComment', function (ctx) {
  let data = ctx.request.body
  if (data.id && data.comment) {
    console.log(data.id, data.comment)
    ctx.body = {
      errno: ,
      msg: 'ok',
    }
  }
})

app.use(KoaBody()).use(router.routes()).use(router.allowedMethods())

app.listen(, () => {
  console.error(`服务器启动成功：localhost:${}`)
})

           

3.在package.json中scripts中添加运行命令

4.运行

npm run mock

即可开启本地测试服务器
